x264 and Sony PSP? [Archive]

http://x264.nl/psp/ (this link is really made for browing with your psp)

Grab: http://x264.nl/psp/x264-psp.exe (self extracting 7zip)

You basically just use the Default x264 settings.
But the PSP requires 15fps or 29.97 to run!

These few files allow you to simply encode with your .avs to a PSP compatible file (also the .mp4 file is edited else it won't play, Atomchanger, http://pspvideo9.com, does this)

readme.txt

This is experimental version 0.00001 or 0.000001, and encodes with these x264 settings:
--progress --bitrate <bitrate here> --analyse p8x8,b8x8,i4x4 --output video.264 psp.avs (Default profile)

1: place your AAC file as audio.aac into the x264-psp dir
2: modify psp.avs, can be your own .avs <-- JUST READ THE NOTES in psp.avs!
3: place the latest x264.exe in the x264-psp dir
4: edit psp.bat and set the bitrate
5: run psp.bat
6: output file: MAQ00264.MP4 copy to PSP:\MP_ROOT\100ANV01\

psp.avs

# ... your normal .avs contents here, just note:
# - AviSource("movie.avi", false, fourCC="XVID") - sample how to re-encode your divx/xvid movie to x264-psp
LanczosResize(368,208) # note the PSP resolution (this is widescreen), 320x240 for fullscreen
ChangeFPS(29.97) # note the FPS change to 29.97, needed for PSP AVC playback (remove when your video is already 29.97 FPS)

psp.bat

start /belownormal /b /w x264.exe --progress --bitrate <bitrate> --analyse p8x8,b8x8,i4x4 --output video.264 psp.avs
start /belownormal /b /w MP4Box.exe -fps 29.97 -add video.264 output.mp4
start /belownormal /b /w MP4Box.exe -fps 29.97 -add audio.aac output.mp4
start /belownormal /b /w ATOMChanger.exe output.mp4 MAQ00264.MP4 AtomAVC.ini

This is all very basic, but works fine.
If you have used megui with the latest mp4box to create your AAC file in the .mp4 container, you can just do: MP4Box.exe -fps 29.97 -add video.264 megui_audio.mp4 and remove the add audio part!

@MuTeK thx for the link

@bob0r Thx for the very quick answer and for this very fine guide....I am on for testing ;)

:thanks:

Gunhed

hmmm

with every encoding done that way my PSP locks up and I have to push the power button for several seconds...

could someone give me a hint?

I used x264 v291 and v292 ... always the same...

What is your PSP Firmware?
Post your .avs file if used
Post your x264.exe settings
Is the video 29.97 FPS?

New to try:
Your audio file, is it AAC LC? <-- i forgot to mention but your PSP AAC LC file MUST BE 48KHz (48000Hz) (sorry will update it in readme.txt and psp.avs later :o)

Gunhed

17th September 2005, 06:54

Thx for your info

you were right.....the audio was my problem...
I used MeGUI before...

I converted the audio again with belightgui ... selected the aac-lc profile and now it works :)

many thx ;)

Am playing with this now, as there are some DVD's I am trying to convert, that suffer from lipsync issues, when I use my previous tool (PSPVideo9).

I have my VOB files on my HDD, and using MeGUI, and x264 (latest). My avisynth script is as follows:

DirectShowSource("I:\Ripped\Pheonix Nights S1\VTS_02_1.VOB")
LanczosResize(368,208)
ChangeFPS(29.97)
ConvertToYV12()

I run the resulting file through AtomChanger, and it reports to have changed the atom. The resulting file appears to be unplayable. VideoLAN crashes, Quicktime 7 does not play it, PSP says it's corrupted. I have tried the unAtomchanged version, with the same results (so it's not that).

What is slightly confusing, some peiple seem to be splitting the audio and then encoding the video and audio seperately, and then re-joining, I am not doing this (reading from the VOB), is this my problem???

Gunhed

19th September 2005, 20:16

yes you have to split it.

convert the video with x264 and the audio with besweet...then join them with mp4mux as bob0r said.

I use x264 now to 2pass my Video files... nice quality on the PSP :devil:

Doom9

19th September 2005, 21:37

is there a complete set of video and audio specs for the PSP all in one place? I should be getting one by the end of the week so I might add a flag to the settings that disabled non PSP compliant options / enforces them (I'm not fully decided on how to implement it yet) in MeGUI.
Also one thing, what do you guys do with 25fps content if the PSP can only handle 29.97fps?

Gunhed

19th September 2005, 23:20

we have to use ChangeFPS(29.97) in our avs script.

bob0r

19th September 2005, 23:57

DirectShowSource("I:\Ripped\Pheonix Nights S1\VTS_02_1.VOB")

ConvertToYV12()

Why ConvertToYV12() ??? (never used it, for all the samples i tried)

Scarpad

20th September 2005, 05:19

Has anyone written a Guide to follow using this method? Especially in the area of using the synth script ?

Doom9

20th September 2005, 08:05

uhh.. but ChangeFPS only takes care of the video so you'll end up having an audio problem, won't you? Wouldn't you have to perform a proper PAL -> NTSC conversion, including slowing down, pulldown and stretching the audio to make it work properly?

bill_baroud

20th September 2005, 10:01

ChangeFPS changes the frame rate by deleting or duplicating frames.

Looks like it doesn't change the video duration, so audio should mostly be in sync, no ?

Doom9

20th September 2005, 10:27

eww.. duplicating frames? EWWWWWW, evil, bad, nasty, ugly, °@°#§°@#§°#@§

jonny

20th September 2005, 12:51

there is also ConvertFPS (yuy2 only)
it will blend adjacent video frames, the video is smooth (compared to ChangeFPS), but there is some ghosting and lower compressibility

PSP also support 14.985 :D

Doom9

20th September 2005, 13:52

so basically the only proper way to do it is a proper format conversion. How do other psp encoders handle this? It might give me a movitational boost if I were the only one to do it right, but if there's plenty of tools already I don't see the point in spending a lot of time for a really small audience.

bill_baroud

20th September 2005, 16:13

I don't think i'm the most aware (JCVD style :D), but seeing all those big company crap or the "total l33t enl4rgement m3gA s0ftW4rE" out there for PSP, i don't think any of them have bothered to deal properly with this.
A clean Doom9 solution would be a Good Thing™ imho.

Scarpad

20th September 2005, 16:18

The Locked Framerate is the PSP's main nemesis, even the capped resolution limit of 76000 pixels would look ok on it's screen if it offered 23.97 compatibility. The 29.97 setting causes red colored fringing around the image and a certain ghosting element. This is less noticible in AVC but it's still there. I'm not sure if there's a solution short of a firmware change that removes the limitation. The results are not terrible, but the screen could do better.

jonny

20th September 2005, 16:21

I use ConvertFPS or ChangeFPS via AviSynth.
From what i see PSP Video 9 (and all the other tools based on FFMPEG) let FFMPEG doing the conversion (maybe i'm wrong but seems to me something similar to ChangeFPS).

I'm a noob on framerate conversions, is there a better way to convert progressive 25fps (or 23.976fps) to progressive 29.97fps (so without getting some interlaced frames or blending or duplicated frames)?

Scarpad

20th September 2005, 21:22

29.97 is what the Framrate needs to be I'm not sure what the ChangeFPS setting would accomplish

jonny

20th September 2005, 21:26

little OT

i've tryed PerfectMotion ( http://www.goodervideo.com/index.html )
it generates frames! quite amazing, and seems there are no big artifacts
(but it's not free, slow and pratically not usable without a big HD)

I have been using x264 to encode AVC movies for my PSP for long, but this little x264-psp package should still help most starters I suppose, heh.

Note that PSP does support 30fps as well. So there is no need to change 30fps video to 29.97fps.

What a pity that, it seems even by using the latest version of x264 and mp4box, the annoying "sticky frame" problem (2 frames skipped just before an I-frame) still presists. This problem may not be that noticeable sometimes though, depending on the motion nature of the movie, and how often and when an I-frame is used.

so basically the only proper way to do it is a proper format conversion. How do other psp encoders handle this? It might give me a movitational boost if I were the only one to do it right, but if there's plenty of tools already I don't see the point in spending a lot of time for a really small audience.

The only FREE PSP AVC encoder out there is PSP Video 9. It does a pretty good job on format conversion, since it is FFMPEG-based. However, I suppose using x264 "wrapped" inside FFMPEG should have some limtations, and probably may not work as well as using x264 directly. The most obvious problem is that PSP Video 9 does NOT (and probably will NOT) support AVC 2-pass encoding, simply because FFMPEG itself does not support this feature.

is the video progressive or interlaced?
turning 25fps progressive into 29.97 i with 3:2 pulldown, while annoying, certainly is doable, but 29.97 progressive? sure you could pulldown then deinterlace but that's kinda pointless.

jonny

21st September 2005, 20:51

video must be progressive, interlaced material is show on PSP like on a PC monitor (and i don't think you can set an "interlaced flag" in the mp4 file and expect the PSP doing deinterlacing in realtime)

sure you could pulldown then deinterlace but that's kinda pointless.

yep probably you'll obtain something like ConvertFPS

29.97 is quite annoying :devil:
sony take care of us :sly:

I guess I gotta write a pretty destructive review of that device once I get it. Handheld console seen from a video enthusiast's point of view, that ought to be more interesting than the usual raving. With game prices higher than PC prices (even though PC games are harder to develop because they have to work on a gazillion different PCs and not just a simple platform), UMD discs that cannot be copied and are more expensive than DVDs, the company that once sold us MiniDisc recorders as complements for our audio CD now not doing the same for video, there's tons of things that are wrong about this. I know why I like my PC, and why my one and only non portable console was only interesting for about 3 weeks (then I got a PC and I haven't looked back since, and I'll be laughing at people spending money on the new XBox or PS3 as two months later the next gen PC GFX card is going to blow them to pieces).

How about testing the device and form an opinion once you get it?

As a handheld device seen from a "video enthusiast's point of view" i can easily say that it's number one, even given the stupid limits and flaws that Sony more or less made by choice. UMD movies looks pretty impressive (no i wouldn't buy one because i can buy a DVD instead and convert it to "almost" UMD quality) but from a pure "video enthusiast's point of view" nothing comes to mind that beats this handheld device when it plays UMD, and i can't think of anything that beats it when it plays it's nerf'd AVC format either.

And your PC vs Console comments are not something i would expect from someone whos insightfull writing and sharp opinions has impressed me constantly since you launched this site. They are so short sighted and one sighted that it reminds me of MPAA and RIAA arguments :-)

The console owns the gaming market for many reasons, but some of the exact reasons you mention as a plus for PC's are the exact reason why people by Consoles. Who wants to pay 500$ for the best graphics card? who wants to constantly upgrade their computer to play 50$ games? And who wants to fight Microsoft software,drivers and copyprotection in order to play a game you BOUGHT, not that many actually, we/they are a rare breed. Console owners insert the disc and plays.

And even today old consoles with 32/64 mb memory still deliveres impressive games that more than often leaves PC games in the dust, i wouldn't live without my PC but i sure as hell couldn't say no to the fantastic games my consoles give me.

And now to the important part, there isn't any really good software solutions for DVD to PSP conversion. PSPVIDEO9 is nice, but not nearly good enough, not enough control over sharpness colors etc, and the DVD conversion sucks. The best seems to be Nero Recode but it doesn't support PSP AVC, and it's expensive.

I've been checking doom9 for the solution ever since i got mine PSP, after all this is the place where video enthusiast's go when they wonna have fun.

Doom9 here are basic specs that need to be filled in order for the movie to play on the PSP.

Resolution pixels < or = to 76800
Resolution must be in multiples of 16
29.97 FPS
AVC can only be played when it goes through atomchanger

That is really it. It is basically a normal AVC that just needs to go through atomchanger.

Tweak(sat=1.2) is for more vivid colors and Sharpen(0.3) to get a bit more details...otherwise the picture is too blurry....in my opinion

any suggestions?

22nd September 2005, 07:26

@tintin1001: It's not a smart thing to argue with the admin of a board if your points don't live up to the expectations. For instance, you can play AVC on a pocket PC, without any of the limitations of the PSP. You are also not restricted to use Sony sanctioned memory sticks, Pocket PCs often offer even two means of storage extension, both of them both cheaper than Sony's memory stick, and offering a higher maximum capacity (I'm talking about CF and SD), and that have the additional benefit that you can also use them in most of today's digital cameras (CF used to be pretty much the standard but now I'm seeing some convergence towards SD, probably due to size constraints). The PSP has the capability screen and processor wise to beat everything there is hands down, but Sony crippled it. This is even more frustrating than if the device actually had the limitations they placed upon external content, but I'm quite convinced playing 24 or 25fps content would be no problem, and neither would using the full screen resolution, or using specs compliant container for that matter rather than some perversion of the specs along with filenames that make no sense. Strip away all the nonsense limitations, kick out the stupid memory stick for SD, and you'd have a kickass video player, but as it is now, it's a disgrace.. all that potential going to waste.

And your PC vs Console comments are not something i would expect from someone whos insightfull writing and sharp opinions has impressed me constantly since you launched this site. They are so short sighted and one sighted that it reminds me of MPAA and RIAA arguments :-)Are you trying to get striked? Everything I said is true and has been proven over and over again. Your points about price are well taken and just as true, but the two do not conflict in any way or form.
And who wants to fight Microsoft software,drivers and copyprotection in order to play a game you BOUGHT, not that many actually, we/they are a rare breed. Console owners insert the disc and plays.The Xbox would be Microsoft, too ;) And copy protection? Give me a break.. consoles are protected up the Himalayas and people actually get sentenced to stiff fees for unlocking consoles.. imagine prison for somebody who buys a PC game in the US to play it in Europe (oh wait, you can't that because of region codes). You actually need to open up your console and start soldering in many instances to get around copy protection.. on a PC you fire up CloneCD and that's that.

I can add this to the "specs" (i hope is valid for firmware < 2.0 only):

Using mpeg4 sp (i can't check for avc):

witdh = 208 | 336 | 464 gives artifacts and are not usable
height = 272 basically smash the bottom of the picture
i've forgot to mention that the PSP's resizer s***s

we shouldn't forget bugs when we talk about limitations :D

It seems PSP can play 25fps just fine, the problem is just you HAVE to set the 29.97fps(or other compatible fps) flag for the .mp4 file(which then causes desynced audio).

if you can set 14.x and 15, 29.x and 30 fps, just like 48000Hz audio, it surely is true the PSP is limited only by cheap number limitations, and not by its contents.

Doom9

22nd September 2005, 19:36

the biggest problem with the PSP imho is that with all the raving reviews, nobody bothered to properly check out the video capabilities and call Sony on their BS. The PSP technically is the Ferrari of pocket fitting portable media players, but Sony artificially crippled it (framerate, resolution, not specs compliant and last but not least picking an expensive and size limited expansion module technology (to use Steve Job's words: this is greedy, they obviously make money off licensing fees with Memory Stick)) and turned it into a Fiat 500 when playback of your own content is concerned. It could do so much better, all the components are there, and Sony already unlocked AVC on memory stick, so it's all corporate policy. Sony, unlock the darned thing, we want our high resolution AVC at proper framerates!! (yes, we, I got mine today)

jonny

22nd September 2005, 20:25

average people will think they need to buy UMDs to tecnically unlock the full power.

23rd September 2005, 16:38

Well they never stated the PSP would have been able to open and playback AVC in standard mp4 container. They also never stated the PSP would had a full and unlimited AVC playback with no restrictions.
Sony, as every major company, have experince in advertising products but what they did was obviously a marketing move.
Customers (including me) should learn to not trust anyone when buying a product but only multiple and unbiased reviews.

24th September 2005, 14:17

We all know Sony is losing money on every PSP they sell. Right now they rely solely on the sales of UMDs to cover the cost and earn money. So from their perspective, it is quite understandable why they would impose restrictions on the Memory Stick movie playback. Unrestricted playback of Memory Stick movies will obviously affect the sales of UMD movies, and there will be people who buy PSP mainly (or solely) for the movie playback capabilities, and in such case, their game sales will be affected as well. You want unrestricted AV playback on PSP at the first hand? Sure, but you need to expect a much more expensive PSP, to a point where Sony loses nothing or even earns money for every PSP they sell.

I think eventually the current restrictions on Memory Stick movie playback will be gone. Starting from 2.0, they allow AVC on Memory Stick. The next step will probably be flexible frame rate support. As the cost of manufacturing PSP drops, eventually they may even allow full-resolution AV playback on Memory Stick.

yep probably it's only a question of time (and hackers may be faster than sony on unlocking fullres)

the frame skip problem is even more serious on nero avc encoded files(1 ref, all additional option off), only Elecard and SONY IC2+'s file is not sufferd from the problem(and both encoder results low quality pictures), i really curious that why x264 and nero produced MP4 would get frame skip when played on PSP.

azsd

25th September 2005, 09:06

have you tried remux the x264/nero avc files using elecard muxer?

I think Large GOP size can't really solved this problem

- only Main Profile
- only cabac
- max 3 reference frame
- no weighted (bi)prediction
- no reordered frames (b-pyramid)
- no multiple slices

Hi,
a few days ago i tried to convert one of my PAL DVDs. I used ChangeFPS in my AviSynth Script. The first pass was encoded with normal speed, 27.xx fps but the second only with 1.xx fps. 14 hours for the second pass is long.:D Is that normal?!? I never had to change the framerate before.

thx

bill_baroud

26th September 2005, 10:40

rofl :D
Encoding speed has nothing to do with the actual speed of the video ;)
X264 is just a slow codec, if you have a not so fast processor (like 2ghz) 14h for the 2nd pass is just standard...

Okay...than there is something wrong. :) I have an Athlon XP 3200+. Realtime encoding or even more is no problem with a resolution suitable for the PSP or even PocketPC. But if i change the FPS of the video, it's getting very slow.

I'm not new to this stuff but i never had to change the framerate before, that's why i ask. I was surprised. :D

@tintin1001: It's not a smart thing to argue with the admin of a board if your points don't live up to the expectations. For instance, you can play AVC on a pocket PC, without any of the limitations of the PSP. You are also not restricted to use Sony sanctioned memory sticks, Pocket PCs often offer even two means of storage extension, both of them both cheaper than Sony's memory stick, and offering a higher maximum capacity (I'm talking about CF and SD), and that have the additional benefit that you can also use them in most of today's digital cameras (CF used to be pretty much the standard but now I'm seeing some convergence towards SD, probably due to size constraints). The PSP has the capability screen and processor wise to beat everything there is hands down, but Sony crippled it. This is even more frustrating than if the device actually had the limitations they placed upon external content, but I'm quite convinced playing 24 or 25fps content would be no problem, and neither would using the full screen resolution, or using specs compliant container for that matter rather than some perversion of the specs along with filenames that make no sense. Strip away all the nonsense limitations, kick out the stupid memory stick for SD, and you'd have a kickass video player, but as it is now, it's a disgrace.. all that potential going to waste.

Are you trying to get striked? Everything I said is true and has been proven over and over again. Your points about price are well taken and just as true, but the two do not conflict in any way or form.
The Xbox would be Microsoft, too ;) And copy protection? Give me a break.. consoles are protected up the Himalayas and people actually get sentenced to stiff fees for unlocking consoles.. imagine prison for somebody who buys a PC game in the US to play it in Europe (oh wait, you can't that because of region codes). You actually need to open up your console and start soldering in many instances to get around copy protection.. on a PC you fire up CloneCD and that's that.

I own a Pocket PC and am unaware of a program that plays AVC content, TCMP formally Betaplayer is probably the best PPC Player and it does not support AVC. And even on my Axim 30 with 624 Mhz processor, Playback on Nero's really bad Showtime PPC version of it's AVC format leads to a slideshow like presentation.

PSP = Portable Shit Player... :D
however sony told us the console capabilities from the beginning and all customers knew them before buying their PSP.
So IMHO we shouldnt blame sony for not giving us what we want, but we should blame ourselves coz we bought a product in the hope it could be what we wanted it to be, but it's obviously not... and we knew it before buying it...

PMP's are just starting to come into their own so something to pass up the PSP is going to be released. From My reading of the reviews so Far Creative's Zen Vision has a nice albeit Non Widescreen 640x480 screen on it with a 30 meg drive and Xvid and Divx capabilities for $399. And Archos AV500 has a PSP resolution Screen but is more expensive. The PSP if we can get past the Memory stick limitations would be nice if a 4 meg Storage card could come out cheaply. It's still the most inexpensive solution. I dig UMD videos and if Demand can force the Prices under $10 I'm cool with that. Still I own 1200 DVD's and if I could get my own on there with good results I would love it.

THe problem with most encoders out there right now is that there's not a "Gordian Knot" of the PSP world that allows more control. Also most of the encoders User FFmpeg with less than steller results. I'd like an encoder built around X264, especially built for the tweaker.

I think Large GOP size can't really solved this problem

Large GOP size definitely doesn't solve the problem. You just see sticky frames less often.

Elecard muxer doesn't work on my PC as I don't have enough components to run it. If someone has this muxer working, please try and let us know if this will help solve the sticky frame problem.

your computer is slow. x164 encoding s slow because the settings are much more complex than divx6 or xvid. Therefore the encoding will naturally be slower.
encoding speed has nothing to do with framerate(although increasing the framerate increases the number of frames processed requiring more time but doesn't change the fps of the encoding process.) The speed should be unaffected whether the clip is 23fps or 120fps.

To make it short - my computer is not slow. :) I have an Athlon XP 3200+ 1GB Ram, should by enough.

I know that x264 encoding is slow but not with resolution suitable for PSP. Without frameconversion i can encode with 20-30 fps in both passes. With conversion it starts with 20-30 fps and ends after hours with 1 or less fps. That's the problem. If it would be constantly slow, ok. But it is not. I use Animatrix - Final Flight of the Osiris (16 min PAL, 25 FPS) for my tests.

As i said, DivX6 works and i know DivX not an MPEG4-AVC codec. :)

I'm german. Perhaps i have some problems to explain my what i want. :)

A lot of PPC talk here.
It works with my Axim X30 an TCPMP but you need the AAC plugin from RareWares, too. But as you said, it's like a slideshow and the processor is working at 624 Mhz.

Do not judge the PPC's AVC decoding potential based on this!!
TCPMP is currently not optimized for AVC playback. The ffmpeg plugin as a whole is also not optimized nearly to the extent that is the ASP decoder. Work is in progress on a decent AVC decoder, but if you don't have a GPU, you might still be lagging slightly at full resolution, full framerate AVC playback.

Ever try to play XviD files with Qpel/GMC on a PPC? Compare it to the decoding speed of the same file without Qpel or GMC. It's over twice as fast without them--even more of a difference if you are using a PPC with a GPU. Why? TCPMP resorts to the ffmpeg's ASP decoder for content with Qpel and GMC, so this tremednous speed difference is just a taste of the optimization likely to come out of a real AVC decoder plugin. Over twice as fast in a new release? Maybe ;)

That is all.

If you play/encode H.264/AVC movies for PSP, you should update your PSP to 2.50.

If you have experience in encoding AVC movies, you should know that there is a "sticky frame" problem (2 frames skipped before every key frame) for any movies encoded with PSPVideo 9 and any encoder other than the official IC2+. Out of surprise, I notice that this sticky-frame problem is GONE in PSP 2.50! I have tried all my previous movies encoded in x264, and they all play PERFECTLY! If you are serious about quality and smoothness of your AVC movies, upgrade now!

Yeah I know those are the options psp.bat has chosen by default. I thought, perhaps, you may know what other options are usable.

Though I've never used the cli encoder without a GUI, it would seem that max ref frames are not set, no b-frames, sub pixel refinment is not chosen, same goes for motion estimation. What are the defaults? (yes i searched)

I'm using Megui aswell to encode movie for the psp, but I"m having issues playing them back.

From what I understand the psp supports main profile but not high profile.

But does it support B-frames? The deblocking filter?

Every video i seem to put in the psp, even if it doesn't play when i press information it tells me it's 768kbps video and 128 kbps audio. Does that mean i have to use those settings or will lower bitrates play fine?

I'm using what bob0r linked to but reomving the encoding command from the .bat scrip.
2 ref
2 B-frames (seems no limitation)
most of the tools are supported, like CABAC, weighted b, deblocking etc.(although many of them are not used in the official tool encoded AVC MP4.)
and with firmware 2.5, the GOP problem is solved, so there's no need to set a large GOP now.
the displayed information is read from the uuid head in the MP4 which is not related to the real bitrate.

Modified
I've tested 2 ref and 4 b-frames Nero AVC. it can be played without any problem on psp(FW2.5). 3 ref will cause "unable to play" so I think 2 ref is the limitation.

UPDATE:
Ok, when i use the same settings with MeGUI 2Pass Encoding, my problem with the slowing down second pass is back :(

I'll test a few more settings.

UPDATE 2:
No matter what settings for b-frames, weighted prediction or things like that i use, in combination with 2pass encoding and changing the framerate from 25 to 29.97, results in a second pass which is getting slower and slower. From 30 fps at the beginning to 1 fps or even lower at the end.

Can someone confirm this? Is it normal?

Imho the best way to get video onto a PSP is with a v1.50 and a homebrew decoder. Currently under development is PSP Media Player v0.0.5. While it is still very early days it looks promising, it plays back AVI/OGG/WMA/MP3/XviD/DivX. While not perfect, as there are sync problems (for the higher res clips) it does remove the Sony limits. Hopefully it can do the decoding of normal XivD encodes with a resize to the pixel display on the unit. I’d put my money on something like this before a Sony authorise player, also with a 4GB hard disk in the works as an add on it could become very tempting.

Forget about ever seeing a homebrew player that can play SMOOTH full-screen movies. PSP's CPU is NOT as powerful as you may think. It simply CANNOT handle pure-software full-screen decoding. AVC playback is smooth on PSP simply because it is hardware-accelerated, something which practically CAN'T be used by homebrew for technical reasons.

I've tested 2 ref and 4 b-frames Nero AVC. it can be played without any problem on psp(FW2.5). 3 ref will cause "unable to play" so I think 2 ref is the limitation.

You can use 3 ref. You just can't use any b-frames at the same time.

I disagree, while this is probably true for avc (atm), imho smooth 480x272 xvid @24-25 fps is already possible. The CPU alone can't do this, but using the second CPU (the ME) some chunks of code can be pushed to 2x (things are moving fast, ME & VFPU are already *in some ways* usable ^^).
I think optimizing the color space conversion and the idct could be enough for a really big speed improvement on PSP Media Player (experimenting i've already got yv12 to rgb working in this way).

As far as I know, the average FPS the existing homebrew players can achieve is below 15. Some movies with high bitrate and complex motions are even slower. You may overclock the CPU to yield better results, but what's the point if the battery will run out in like 2 hours?

i'm testing video only atm, 480x272 mpeg4 sp @ ~800-900 kpbs, with the current player should give 17-19 fps.

All of this with the cpu @ 333 mhz

I'm not quite sure. I'm using avisynth 2.5.5 but my script is very simple:

I updated to 2.5.6 nothing changed...again :)

Avisource(".../GunXsword.avi")
BilinearResize(368,208)
ChangeFPS(29.97)

It's something like that I can copy the exact script when I'm back home.

Have you tried filtering in vdub and outputing it as an uncompressed file then running it through megui? Or did you use the VFW codec?

I used the VFW codec. I will try to compress an avi, too.

Hi! I am using the x264-psp pack and I have some questions! Is there any problem if I make a 2 pass encode instead of 1? Can I use a resolution that is not 368x208 and 320x240? Can I use reference frames and b-frames?

Thanks!

DryFire

23rd October 2005, 20:05

2 pass will work fine. As for the resolutions, you can go smaller however, I don't think full resolution is supported.

as for reference frames 2 is the max with 1 b frame or 3 w/o a b frame (according to the posts above).

I invested some hours of encoding and found following settings working:

x264.exe --progress --bitrate 384 --ref 2 --mixed-refs --bframes 16 --subme 7 --b-rdo --weightb --trellis 2 --analyse p8x8,b8x8,i4x4,p4x4 --me esa --merange 64 --no-psnr --output c:\psp\video.264 c:\psp\psp.avs

IMHO it's the highest possible setting.
and sloooow...
remove "-me esa --merange 64" for faster encodes

PSP can't handle more than 2 ref-frames and can't handle pyramid-b-frames.
High Profile isn't useable too.

I was having fits trying to figure out what I was doing wrong with this. I ended up figuring out that my PSP is very picky on the AAC encoder used. It finally worked when I used BeLight to convert the ripped audio track via AAC FAAC encoder engine with output sampling rate of 48000, and options of wrap aac stream in MP4 and profile LC. Hopefully this insight will help anyone with files that were locking up thier PSPs. My PSP firmware is 2.60 and it works fine.

I used this psp.bat:
start /belownormal /b /w x264.exe --progress --bitrate 384 --ref 2 --mixed-refs --bframes 16 --subme 7 --b-rdo --weightb --trellis 2 --analyse p8x8,b8x8,i4x4,p4x4 --me esa --merange 64 --no-psnr --output video.264 psp.avs
start /belownormal /b /w MP4Box.exe -fps 29.97 -add video.264 audio.mp4
start /belownormal /b /w ATOMChanger.exe audio.mp4 MAQ10001.MP4 AtomAVC.ini

The one problem I see is that --bframes 16, try put 2 or 3. Actually, I tried with 4 and it works too, but seeing 4 bframes in a row is a rarity, and 16... well...

btw add this last line

ffmpeg.exe -an -y -t 0:0:0.005 -i psp.avs -f image2 -s 160x120 MAQ10001.THM

for a psp thumbnail ;-)))

make sure to choose the rigth frame to export ... (-t 0:0:0.005 is timeset... ) ...

for me i follow these steps :

- make avs with resizing (16/9 - 4/3 - 2.35)
- extract audio as wave
- encode wave to lc-aac via faac (not sure he-aac is supported)
- encode video to mp4 via x264.exe
- mux aac and mp4 into new mp4 via mp4muxer.exe
- change header of mp4 with atomchanger.exe
- generate thumbnails

i make a little soft to use it since i want to make also mpeg4-asp mp4 ;)

ffmpeg can directly make audio/video mp4 files with lc-aac and xvid as codec...and can resize also so i wonder if it can encode using h264 codec...there's still the problem to update h264 encoder when using fffmpeg ;-)

EDIT:I did a little searching.Is MEGUI the one i should use?What bitrate do you guys use for avc,and is there a way to put subtitles?

Hyper Shinchan

16th December 2005, 17:52

Well, you need Atom changer (included in this link http://www.x264.nl/psp/x264-psp.exe) and then you have to hack your MP4 with this tool (you can use it with commandline or editing the batch, I prefer to use it with command line).
About the settings I use almost all the Main Profile L3 features excluding Pyramid B-frame and I set 2 B and 2 Reference frames (but you can rise B frames lowering Reference and viceversa, but I'm not sure about it). For the bitrate I suggest something like 300kbps or 400kbps but AVC is really powerful and with anime contents you can use really low bitrate (I don't know about movies because I watch only anime).
Anyway that .exe include a batch with low settings that you can modife as you wish, i think that it's good for a newbbie.Or you can use 3GPP Converter, but it's not so good, imo, also if it uses X264 libraries with FFMPEG.
C'ya.
EDIT: keep in mind that your AAC must be 48 khz and your video frame rate 29.97 fps, but maybe you've noticed it.

qyqgpower

17th December 2005, 13:59

with 2.6 firmware you can play 24fps(and 23.98 etc.) AVC now. just use x264 bundled ffmpeg to encode a 24fps clip and give a try.
if you use x264 or ND to create a 24fps clip and go through psp video 9's atomchanger to get a psp-playable AVC, you need edit 0x00A0~0x00A7 to 00 17 F9 DC 00 17 F9 DC to get a sync clip.

so I have compiled an atomchanger which won't fix FPS to 29.97 but depends on the input file's FPS.
Use this INI file with this atomchanger:

I have been reading through this discussion for some time and I have had some problems.
#All this happened under Linux #
I have been able to make PSP videos using ffmpeg on my PSP Fimware 1.51. But after upgrading to Firmware 2.0 I have not been able to do any of that. How do i encode videoes under ffmpeg or anyother application under Linux to play on my PSP with firmware 2.00.
I have been playing around with ffmpeg and I compiled as such.

./configure --enable-mp3lame --enable-faac --enable-faad --enable-amr_nb --enable-amr_wb --disable-ffplay --enable-small --enable-memalign-hack --enable-gpl --enable-xvid --enable-dts --enable-a52 --disable-vhook --enable-x264 --enable-pthreads

And when I encode a video in h264 format

fmpeg -i SOME.avi -b 384 -vcodec h264 -acodec aac -ac 2 -ar 48000 -ab 48 -vol 256 -f psp -r 29.97 -s 320x240 -bufsize 256 -g 250 -coder 1 ~/M4V00022.MP4

#Please note I got this cmd line from the pspvideo9 debug console output.

The psp cannot read it. It says the file cannot be played.

Is there anyway to make video into PSP format with out running on PSPvideo9 under windows?

I personally think the PSP firmware is being very picky in looking at the files and seeing if it is not compliant it will drop the file.

So in short does anyone have any ideas how to convert an xvid avi file into a PSP MP4; with AVC encoding ; under linux. Or do I just need to upgrade my firmware?

Yes, everytime before I update I uninstall MeGUI and x264. I only convert PAL 25 FPS DVDs (mpeg2source) to MP4/264. Normaly I encode directly to 264. If i forget to switch and i get an MP4 file, i extract the video. In the end i always have an 264 file.

I uses this line to demux the video "mp4box.exe -raw 1 Video.mp4"

Versions:
GKnot: latest available to create an avs file
AviSynth: 2.5.6
MeGUI: latest version

this atomchanger will write the fps flag according to the input file, so it will work with any file in any fps. but since 2.6 psp only supports 15, 24, 23.98, 23.976, 29.97 and 30 fps, of course you can not get a sync 25 fps playback.

The only way to play it again is to reset the PSP and fast forward to where I was last watching! Also if i try using the go to function, it completely freezes the PSP and once again I must reset. I used to encode .avcs with PSPVideo9 and they did not have this problem. My current process is avi-MeGui-MP4Box-Atomchanger. Any ideas what the problem might be?

Bah, first it's "can't play AVC from memorystick", then it's "only plays AVC at a limited framerate", now it's "only plays AVC at NTSC framerates", but the PSP has no problem playing full resolution AVC at higher bitrates (http://www.engadget.com/2005/11/30/psps-2-60-firmware-does-480-x-270-video/#comments) and I suspect that supporting 25 fps is also only a political question, but what do you expect from a company that takes over your computer?

To be fair it is getting better. 23.976fps is a god send. The problem I'm having right now isn't resolution dependant though! Any avc's I am putting on the PSP are reacting in the same way. This is definately a new thing though and I don't know whether the problem is with the new firmware 2.60, or with the encoding process. When I get home I will try encoding an avc with PSPVideo9 and see what happens. In the meantime, could someone who has the 2.60 firmware just check whether they are able to come out of the movie and then back in to it succesfully?

4. Switching back to last episode

= Starts again from the beginning

Futurama filename: MAQ30001.MP4
Chappelle Filename: MAQ40001.MP4 - MAQ40007.MP4

Perhaps the behavior (starting or not starting) has something to do with the filename? My encodes are a little older. Tomorrow i'll encode a new movie.

to the "can't resume/jump to problem":
it only happens on 2.6 psp,use only these settings for ref and bframe:
1ref + 1bframe
2ref without bframe
3ref without bframe

all other settings will cause "can't resume/jump to problem".
the reason is 2.6 have changed some methods in these function. in previuos version you can only resume/jump-to at the nearest I frame, but in 2.6 you can resume/jump-to at any frame. so a new bug in decoding multiple bframes clip have occured. hope will fix it in future version.

assumefps will change playback speed, and of course will out of sync.
i think changefps won't cause ghost effects(convertfps does), it only deletes or duplicates frames, it is recommended for anime. convertfps is recommended for real life footages.

Clown shoes

26th December 2005, 02:31

The best way to go from 25fps to 23.976fps is by slowing down as you do not make any alteration to the frames themselves. Both Besweet and Belight have a simple tick box to convert audio from 25fps to 23.976fps. If you are genuinely into upmost picture quality (and who isn't) then this has to be the only option. Try it. I don't think you will be dissapointed.

--me esaPlease don't use that unless you're running a contest of which AVC encoder is the slowest.

And why the low bitrate? the PSP ought to be able to handle higher bitrates, does it not?

Even though I have a PSP (recently flashed to the 2.60 firmware even.. but that's the only thing I've done with it since the day I got it) I can't help with your problems.

yep, thats sorted the threads thing, thanks :)

i am just testing things at the moment, but i actually found the stuff wasnt too bad at all at around 200 as im going more for quanitity than quality. have a lot of flight from london to dallas/sf and wanted to make sure i had plenty of stuff to keep me going for the long flights.

oh, and i shall make sure --me esa is taken off, thanks

with 2.6 firmware you can play 24fps(and 23.98 etc.) AVC now. just use x264 bundled ffmpeg to encode a 24fps clip and give a try.
if you use x264 or ND to create a 24fps clip and go through psp video 9's atomchanger to get a psp-playable AVC, you need edit 0x00A0~0x00A7 to 00 17 F9 DC 00 17 F9 DC to get a sync clip.

so I have compiled an atomchanger which won't fix FPS to 29.97 but depends on the input file's FPS.
Use this INI file with this atomchanger:

this is good news and i have made my first 23.97 clip which played, but suffered from audio out of sync. could you tell me what you mean by this:

you need edit 0x00A0~0x00A7 to 00 17 F9 DC 00 17 F9 DC to get a sync clip.

i guess as it means nothing to me, its probably out of my limited scope :D but i am willing to learn :)

Hey Deets, should I presume your sources are 25fps? If so, all you need to do is slow the audio in Besweet. There is a very simple 25 to 23.976 tickbox you can use.

All my PSP material is now 23.976 and it looks great! All we need now is for them to unlock the full resolution for us, which is definately do-able as Doom9 pointed out earlier in this thread (http://www.engadget.com/2005/11/30/...video/#comments)

weird locking up problem....

i dont just get videos that say cant be played, i get some that dont give the message and the screen goes black and the only way to get the psp back is to tak out the battery...

heres the megui log of a test i just did:

"C:\Program Files\x264\x264.exe" --bitrate 220 --keyint 300 --ref 2 --bframes 3 --subme 7 --weightb --analyse p8x8,b8x8,i4x4,p4x4 --qpstep 1 --me esa --threads 2 --progress --no-psnr --output "C:\psp\psp.264" "C:\psp\psp.avs"

mux it using the same mux bat i use for all other clips, but the clip causes a hard lock up...

also, i say 1 thread in megui but it always puts 2 anyway

I was just looking at your MeGUI log and I noticed you have 2 refs and 3 bframes. That could well be one of your problems. It was definately causing problems for me such as crashing when using the seek and no way to resume once stopped without restarting the PSP. Qyqgpower mentioned earlier;

on 2.6 psp,use only these settings for ref and bframe:
1ref + 1bframe
2ref without bframe
3ref without bframe

Hope this is of some help mate.

indeed, the psp is keeping me up ;) i have since found out my computer doesnt like x264 with 2 threads and that was the main issue, all encodes now work just fine. although your right, i did get the seek issue for messing with the b frames, i was just trying all options as i didnt know it was the 2 threads causing me grief!

and sharktooth, I did try your profile first but it crashed, but I only just worked out its my setup and not megui or the profiles :) thanks for them though, ill just stick to yours from now on, make my life much easier ;)

else if strAspectRatio = '4/3' then

else

but in pspenc software it seems the author add black borders in order to use
classical 16/9 resolution (ie : 368,208)

looks the same for me...except that the black borders are less black that no borders lol

5th January 2006, 19:18

I have followed this thread for a while now. I am having trouble with the last step of a 23.976fps AVC file. When I used the atomchanger.ini posted on page 6 of the thread, the PSP (FW 2.60) would say "corrupd data" or something similar. Comparing the original ini with the new one, I added the line codec=2 to the new ini (leaving all other lines the same) and the files now play, but are out of sinc severely. They play fine on the computer. The files are Nero Digital AVC with 48Khz audio. Other than needing to use the extra line "codec=2". I can see no difference to what others are doing.

Any suggestions?

deets

5th January 2006, 19:26

did you use the atomchanger in the zip in the post as well as the new ini?

nrx][Natas

5th January 2006, 19:26

For me it works without the extra line but, did you change the audio framerate, too?

willie1

5th January 2006, 19:42

I tried several combinations of atomchanger and the ini. Maybe I will clear the folder and use the atomchanger from the link with the ini provided and see if that works. I did not change anything from the Nero Digital file in the audio. It is playing about 25% too slow. It does not appear that the video plays too fast, but that the audio is slowed down. I'll post back if clearing the folder works.

willie1

5th January 2006, 20:03

The ini now works without the extra line, but the audio is still out of sinc grossly. What app do I use to edit the audio in as per the post on page 6? :

"with 2.6 firmware you can play 24fps(and 23.98 etc.) AVC now. just use x264 bundled ffmpeg to encode a 24fps clip and give a try.
if you use x264 or ND to create a 24fps clip and go through psp video 9's atomchanger to get a psp-playable AVC, you need edit 0x00A0~0x00A7 to 00 17 F9 DC 00 17 F9 DC to get a sync clip.

so I have compiled an atomchanger which won't fix FPS to 29.97 but depends on the input file's FPS.
Use this INI file with this atomchanger:"

I am not sure where I can edit this line.

5th January 2006, 20:33

whats the original fps, 23.97?

try using besweet/belight to convert your audio to aac

willie1

5th January 2006, 20:52

Thanx for the suggestion, but I have done that with the same problem. I used belight with the NAAC settings. The original file is SW episode III- legally purchased dvd- and 23.976 fps.

Problem fixed: I used YAMB1.4 and remuxed the video with the video set at 23.976fps, and the audio set at 29.97fps. Perfect sinc and stutter free playback. This must be a peculiarity of the Nero Digital muxing since others aren't posting the same problem with the MeGUI encodes.

Thanx for all the suggestions.

deets

5th January 2006, 20:58

yeah thats very weird...

i use besweet beta 8 with the nero digital encoder engine and then mux using megui, works like a charm :D

sevEren^^

6th January 2006, 23:43

Would it be possible for megui's bitrate calculator and muxer (YAMB frontend) to take the framerate/length of the clip from the avisynth script rather than the actual avi file being used? Whenever I use the "assumefps()" command, and open the avs, the length in the bitrate calculator needs manually adjusting, and also it's necessary to mux using the raw .264 video and manually specify framerate, otherewise the resulting mp4 file has the original avi framerate instead of the one specified in the avs file, and there is a sync issue. I normally open the avs in virtualdub and check the file properties which gives the correct length/framerate.

Encoding avi files without doing anything to change the framerate works fine obviously.

Other than this tiny point, I think megui/x264/naac is the best psp video solution around, and the results with 2 or 3 pass encoding are fantastic. Well worth the little extra time spent tweaking to get a "perfect" encode, than use a single-click solution (e.g. PSPVideo9) which lacks the more advanced features. Thanks very much to all the devs who might be reading. :) Great tools.

willie1

7th January 2006, 04:58

I agree, this is a great set of tools, but it takes a little bit of tweaking to get things to work right. (I just noticed the "new" limitation on b- and reference frames with 2.60fw.) I still like the Nero Digital AVC image a bit better, but x264 is very good.

Hyper Shinchan

7th January 2006, 05:07

I personally prefer X264, I don't knwo it looks better at lower bitrate for me. Anyway what do you use (PAL users) to conver fps from 25>24? I've tried convert fps but it looks bad, at least with anime source, generally I use change fps, but you will lost frames.... Sony's shit.....
P.S.: But I don't have any problem with audio/video sync.
EDIT: @Hyper Shinchan:

7th January 2006, 13:22

Would it be possible for megui's bitrate calculator and muxer (YAMB frontend) to take the framerate/length of the clip from the avisynth script rather than the actual avi file being used?Umm.. MeGUI takes it from the script. And what is your beef with the AVI? There are no AVIs in MeGUI unless you decide to output some.

Here's a little experiment I ran: my usual codec comparison matrix clip at 23.976 fps. I open the avs in MeGUI, then open the bitrate calculator. Number of frames: 196159
FPS: 23.976
Length: 2:16:21

Then I edit the script and add assumefps(25.00), open it again and go to the bitrate calculator again. Now it shows:
Number of frames: 196159
Framerate: 25
Length: 2:10:46

So, as you can see, making the change in the script is picked up by MeGUI.. the number of frames is obviously the same, but changing the fps also changes the movie's length.
The same goes for muxing.. in automated mode MeGUI takes the fps from the source (so 25fps once I added assumefps) and plugs that into the muxer.

deets

7th January 2006, 15:53

edit: oops, missed willie1 reply saying the same thing!

as others said earlier in this thread, i use assumefps(24.000) and then in besweet i slow the audio down from 25 to 24 in the advanced settings section.

as said, it doenst mess around with any of the frames so is the smoothest option and the change in speed wont be noticeable :)

looks great :D

i converted my memento dvd the other day, 190mb for the 2 hour film! looks great, sounds okay

sevEren^^

7th January 2006, 22:33

So, as you can see, making the change in the script is picked up by MeGUI.. the number of frames is obviously the same, but changing the fps also changes the movie's length.
The same goes for muxing.. in automated mode MeGUI takes the fps from the source (so 25fps once I added assumefps) and plugs that into the muxer.

Hmm, this must be something I'm doing wrong then, as the bitrate calculator is picking up the original file's framerate rather than the value I enter after the AssumeFPS command in the avs. I'm using the AssumeFrameBased command. Could this be messing it up perhaps? My apologies anyway, I assumed it was megui causing this, but it's obviously something unique to my setup. I'll try and find out what is causing it. Thanks for your help. :)

edit: This is only happening when I specify 23.976 as my framerate in the avs file. If I specify AssumeFPS(30), (25), or (24), megui's bitrate calculator picks it up fine as the correect value. When I use AssumeFPS(23.976) though, it always shows up as 25fps in the calculator. If I open the avs file in VirtualDub, and go to "File Information", it shows up as 23.976 with the correct time. My fault for not using 24fps I guess.

Hyper Shinchan

8th January 2006, 01:05

Have you assume fps then slow the audio in besweet with the OTA track adjustments? This will leave you with all original frames and no playback problems. The disserence in speed is not significant enough to be a distraction, and is actually how film is converted to PAL.
I was thinking about it and I'll try it now, blending frame really mess up things with animes (maybe also with movie, but who cares about movie???).

The new psp profile (sharktooth) has 2 reference frames and no b-frames as default. Someone posted previously that they could get 1-b and 1-ref frame to work with FW2.60. I have been unable to do so. Are there any other changes that need to be made to the profile to get it to work with b and ref frames? It seems to me using b-frames would greatly help the compressibility.

Well, I have a 2.0 psp and I can play videos with 2 refs and as many bframes as I want (I have been able to play a video with 7 consecutive bframes). I am not sure if the bframes cause dropped frames or whatever (I will eventually try), but I think that bframes were removed because they were causing problems with the seek/resume functions in 2.6 (I have no seek resume problems with 2.0).

willie1

10th January 2006, 07:32

I don't think its something to do with the b-frames anymore- None of my x264 encodes work. I have tried no b-frames and they still don't play. My Nero Digital avc's are fine Its not audio related as I'm using the same audio settings for all of my encodes, x264 or Nero. The default profile isn't working and the default minus b-frames and even 1 reference frame isn't working. I disabled p4x4 which is enabled by default, no help. The only options I'm using are CABAC,I4x4, P8x9, B8x8 deblocking, and 1 reference frame. I've got main profile, and unrestricted level selected. The PSP recognizes the files, but locks up as soon as they are played. My muxing options should be fine as the Nero AVC is muxed the same way- Yamb1.4 and MP4Box.

Here is the command line:
"x264.exe" --pass 2 --bitrate 250 --stats ".stats" --ref 2 --analyse p8x8,b8x8,i4x4 --direct none --progress --no-psnr --output "D:\x264-psp\test1.mp4" "D:\x264-psp\test1.avs"

Any thoughts?????

10th January 2006, 12:31

Dear Willie1, try to upgrade to the latest x264 build and use the included psp profile with the megui-x264. Or maybe you changed something in the audio? Or maybe you passed something strange to mp4box? Good luck!

10th January 2006, 12:57

As I posted, I have working files from Nero Digital AVC with belight encoded audio, muxed with Yamb. I know the correct framerates,filenames, and framesizes. I have working files(ND AVC), and even recognized x264 files, but they lock up. I am using x264 396D, downloaded this last Saturday.

Could you share the x264 command lines you are using, or better yet, try the megui with the standard psp profile and post the log (that is, if the video still doesn't work)? (and maybe also post the avs file, the mp4box command, and so on)

@Bond: I have working AVS files on the psp so I do know how to do the atomchanger thing. To get a working Nero digital, I encode the avs in Nero, encode the audio with belight, mux the audio/video with Yamb(mp4box), then atomchanger, and finally copy to PSP with the appropriate file structure. I have both 23.976fps and 29.97fps Nero AVC/ belight/ Yamb(mp4box)/ atomchanger files working. The MeGui files are recognized by the psp, but in the properties it sees th4e video at 768kbps, and if selected, the PSP locks up.

try changing --threads 2 to --threads 1

i know it sounds weird, try it with a short clip and see if it works. my psp locked up when i used 2 threads in x264 even though the file played fine on the pc etc.

in megui goto tools-settings and untick "automatically set number of threads" as this puts in 2 automatically if you have a HT or dual core cpu

I'm only using 1 thread. Thanx anyway.

11th January 2006, 02:32

I'm only using 1 thread. Thanx anyway.

not according to that log you posted...

"C:\Program Files\x264\x264.exe" --pass 2 --bitrate 250 --stats "D:\x264-psp\test1.stats" --ref 2 --analyse p8x8,b8x8 --direct none --threads 2 --progress --no-psnr --output "D:\x264-psp\test1.mp4" "D:\x264-psp\test1.avs"

you may only be putting one thread in x264, but megui will change that to two if it detects a HT or multi core CPU, you need to manually turn that off as i suggested.

just try it on a 1 minute clip...

11th January 2006, 04:08

Thanx Deets, I had previously unchecked that box (at least I remember doing that) and setting it to one thread, but when I went back, it was set again to auto. (probably when I reinstalled everything.) The file you provided worked, so that's probably the problem. I am going to try a test encode of my own now. Thanx again.

12th January 2006, 18:43

@sevEren^^: I've made the same findings regarding the framerate reported.. no idea though why this happens.. I'm still using AVIFile to read the framerate. I'll have to step through the debugger once.. I'm having some nasty thoughs why this is happening.. I suspect the framerate returned isn't 29700/1000 and 23976/1000 (which would be properly mapped) but something in that range only, and so it will not be picked up because I look at an exact match in the dropdown.. not some kind of closest match. If there's none found, the calculator defaults to the default fps which is 25.

Glad you were able to recreate this problem, as I was beginning to suspect it was a software component on my machine that was to blame. I look forward to a fix in a future build of megui. I didn't realise that 25fps was the default value that is used when an exact match isn't found, I thought it was picking up that number from the original avi file somehow (which was from PAL source 25fps). doh. :) Tbh though, it's a tiny bug and it's fairly simple to workaround anyway. :)

Hi there all,

Could somebody tell me if there is any Mac way to get a ripped PAL DVD .vob file onto the PSP at 23.98fps which is now supported. I want to buy a PSP but won't until I know this is possible as I can't stand the sticky/duplicated frames seen when I use iPSP, PSPware, ffmpegX to convert movies.

Really frustrating. No-one seems to have written any updates for any of these programs which will allow playback at this framerate. Anyone kind enough to help?

The audio seems to give me the most trouble. I put this in my psp.bat:

x264.exe --pass 1 --bitrate %2 --stats ".stats" --ref 2 --mixed-refs --bframes 3 --b-rdo --weightb --subme 6 --trellis 1 --analyse p8x8,b8x8,i4x4,p4x4 --threads 2 --progress --no-psnr --output %1.mp4 %1.avs
x264.exe --pass 2 --bitrate %2 --stats ".stats" --ref 2 --mixed-refs --bframes 3 --b-rdo --weightb --subme 6 --trellis 1 --analyse p8x8,b8x8,i4x4,p4x4 --threads 2 --progress --no-psnr --output %1.mp4 %1.avs

This allows me to type psp.bat <filename> <bitrate>, and the script will then run against <filename>.avs, creating <filename.mp4> at <bitrate> Kbps. Originally, I had the batch file do everything to get me the MAQ00264.MP4 file, but I kept getting bad files. Sometimes, they would yield "unsupported format," others, the PSP would freeze. I finally converted the WAV file I had (which was 44100) to 48000 using Besweet. I deleted the original wav file. First, I tried belight, and still got the lockup. Then I tried the same settings on dbpoweramp using Nero AAC (which is what I had been using with Belight) (LC, High Quality, Radio VBR). dbpoweramp worked, and Besweet did not. I had been working on this thing for 3 hours before I finally got a working file onto the PSP, and the problem seems to be the audio. I think this could be an area which could use some serious work.

I spoke too soon. The clip played once. I stopped it before it was finished and tried to play it again, and it doesn't play. It also doesn't lock up my PSP, though.

cbr, lc, 48khz

seems my psp2.5 don't support 44.1khz only 48khz

and with cbr no audio/video desync or pb

lc profile of course :-(

for anime 64kbits
for music or better quality 128kbits -- no more since i listen via headphones..

style have pb sometimes with jh264 when i don't put the maxbitate at 768kbits and you?

Okay, I've been hacking around with this thing for a while now. Here are my program versions:

My psp-encode.bat script contains the following:

x264.exe --pass 1 --bitrate %2 --stats ".stats" --ref 2 --mixed-refs --bframes 0 --b-rdo --weightb --subme 6 --trellis 1 --analyse p8x8,b8x8,i4x4,p4x4 --threads 1 --progress --no-psnr --output %1.264 %1.avs

start /belownormal /b /w ATOMChanger.exe %1.mp4 MAQ00264.MP4 "C:\Program Files\x264\AtomAVC.ini"

Before I encode, I demux the audio from my AVI or AViSynth script using VobSubMod. I then use besweet to convert whatever the audio to a 48000Hz wav file. Once I have crafted my avs file, using psp.avs as a template, I name it something without spaces, let's say, in this case SW_EpIII.avs. I name the wav file above SW_EpIII.wav. Then I run
psp-encode.bat SW_EpIII 256

The script runs against the avs file to create the video, and converts a .wav file of the same name (which you created in the manner above).
I put \program files\x264 into my path, and put atomchanger, naacenc and any other command line tools I use into that directory. The resulting file played multiple times on my psp. I just pulled a short clip so I could verify settings. I will experiment with other quality settings now that I have a basic setting which works. I hope this helps someone out there who was a frustrated as I was. I found naacenc.exe at rarewares.org, BTW.

i found megui to be the best tool to mess around with PSP encodes for video and besweet using my nero dll's to encode the audio.

then i mux with megui and batch it through atomchanger.

my sig contains a basic page with all the info gleamed off this long topic from all the geniuses on here :)

Nice guide you have setup on that site in your signature. I followed it and got beatiful results from my encodes (256kbps video bitraite, nero aac radio vbr profile for audio (75-80kbps)). I was just wondering how one would do this with VOB files instead of transcoding AVI's?

I guess i should use dvd decrypter to stream copy the main movie and audio soundtrack i want, and turn off the file-splitting option so that i get only 1 vob file? Then use DGIndex to demux the audio and create a .d2v, open this in the avisynth creator in MeGUI and choose deinterlacing if the dvd has that, add the avisynth options i want myself, then just encode as usual? After that use BeLight to transcode the .ac3 and then mux the files to a MP4?

Does this sound about right, or am i missing something?

EDIT: Decided to use Gordian Knot to create the avisynth script file, cut away the credits and such. Then just opened the avisynth in notepad, added the options i wanted myself (resize to 368,208, Tweak(sat=1.2), Sharpen(0.3) and assumefps(24.000) (since this is a 25fps pal dvd)). and it seems like its going good (megui-x264 started on second pass now, although it seems like it's going a bit slower than when i transcode avi's, but i guess that's normal, since this dvd needs to be deinterlaced).

EDIT 2: And it worked perfectly :) Although i have to re-encode it, since i tirmmed off the credits in the movie, but i didn't consider that the audio would be totally untouched, so... hehe.

I've started to attempt this venture with one problem: Audio! The video plays perfectly. When I use faac (whether via besweet or faac.exe bia megui), the audio plays about half as fast as it should. If I use Nero or the Winamp AAC plugins (via besweet), the PSP freezes as soon as the video starts.. I've read up and down the threads and was looking for some help.

Edit:
Let me give some specifics
The video is 23.976 FPS
I use BeLight to convert the audio to AAC (always at 64 kbps) and make the output sample rate 48000.

deets

29th April 2006, 19:17

have a look at my sig for some audio info

damrod

30th April 2006, 10:22

have the same problem...was thinking too high bitrate for video
(x264@500 but the max bitrate is around 2000) + audio faac 64kb 48khz)

firmware 2.5

handtruck

1st May 2006, 13:44

Thanks, deets.. Actually used your site as a guideline before you responded but I still have the same problem.. Used a trial of one of those "all-in-one" converters (which I think used ffmpeg for video) and still the audio is too slow.. Is this a firmware issue?
It's weird because
-the file plays perfectly on the computer
-the video plays perfectly on the PSP
-the audio plays on the PSP, but at about half the speed.

It may be important to note that even though the audio is 64kbps, if you look at the information on the PSP, it says 128kpbs. I also tried 128kbps audio with the same problem.

handtruck

1st May 2006, 18:16

Ok, some more information.
I sped up the audio in besweet to be double the original (which incidentally makes the file half as large obviously and half the duration). And this actually works on the PSP. The audio and video match up. However, scrolling and resuming put the audio out of sync (for obvious reasons). This proves that the audio is playing at EXACTLY half the speed. Does this have to do with the 48000 Hz the audio MUST be at for AVC? Is there a way to make the file "LOOK" like it's at 48000 but actually be 24000, the speed it's apparently being played at?

deets

1st May 2006, 19:40

whats the fps of the video?

i personally use nero dll's via besweet and belight and all works great

handtruck

1st May 2006, 20:14

This has happened for both 23.976 video and 29.97 video. I would rather try to use the open source (and free) faac to make this happen if possible, but I'll see if I can make it work with Nero (if I can somehow "obtain" the .dll's)

But this audio issue is just driving me nuts!!!

handtruck

1st May 2006, 22:49

OK, just tried my files on a firmware 2.5 psp a friend has, and they ALL work. This is clearly a firmware issue (I have 2.7). Any ideas?

damrod

11th May 2006, 22:58

maybe a problem with container of audio before final muxing?

i have a strange thing on my pc...

audio encoded in he-aac with winamp codec...property in mpc give 24khz same source with latest neroaudio codec...48khz....both he-aac in 64kb so maybe the psp have the same problem and bug....

presonally i prefer x264@500 than xvid@768kb for my psp since i have only one 1GB MSPro :)

unmei

12th May 2006, 02:26

an AAC decoder that doesn't understand the SBR part of a HE-AAC will only see the "nomally" encoded part, that happens to be at half the samplerate (thus it sees 24kHz for a 48kHz file). I don't have a PSP but from this behaviour and also because other posters mentioned LC i suspect the PSP, or a particular firmware version, cannot decode the SBR part, so don't use HE-AAC but LC-AAC and look if that fixes your problems.

Clown shoes

12th May 2006, 14:13

To the best of my knowledge the PSP will only accept aac as LC. I thought that had always been the case. I am supprised to hear HE worked on any firmware!

hey i jsut got a psp and i have alwyas liked using x264 but for some reason any movie i encode using it for psp it plays for 4 secs then says video cannot played why is this anyone know why??..

i ust the latest x264 codec and use the command line interface encoder.. then use bewseet for audio and mux using mp4mux then run it throught atomchanger.. althought the atomchanger confused me abit cuz i keep reading about these long commands ppl type with 29 fps when mines are 23fps :(..

Hello All,

I'm new on this board as a writer (because I often read this forum and it's very cool!)

I'm currently trying to convert my .mp4 (x264, AAC, 25fps) to psp mp4 (firmware 2.71).

I've tried Deets method on his site, but my psp keeps to say me that my video is not compatible.
In fact I'm asking for help...:):) (thank you in advance)

Here is my method :
VIDEO : Compression through AVS (29.97fps) and command line x264 (last update, no particular option at 768 kps and size of 320*240)
AUDIO : I extract wav from my mp4 original file, then I use Nero digital CLI (free one). I encode with lc at 64000 kps.
I'm muxing with mp4box.
At the end, I'm using atomchanger.

Thanks a lot for your help.

MarcParis

5th June 2006, 20:17

In order to help, here are my parameters : based on what I've found in this thread...thanks to their author!!

start /belownormal /b /w ATOMChanger.exe output.mp4 M4V80021.mp4 AtomAVC.ini

The result is perfect on my computer, but unreadeable on my psp (firmware 2.71).
Moreover the sound, alone, is readable on psp.

Thank you for your help!

Ok thank you for your answer Deets.

1- You're right about MeGui. I've always put 2 threads. I'll compress using command line directly.

2-About the name of the file. When I rename it MAQ00419.MP4, I can't see it any more on my psp. I put this file to the following folder : J:\MP_ROOT\100MNV01
Is it a different folder?

Thank you a lot for your precious help Deets!

MarcParis

5th June 2006, 23:55

Ok I've found the correct folder 100ANV01.
With only 1 thread at compression it works perfectly!!

use megui, its great and can also do your aac using the nero CLI. just change the settings as per the page above about the threads

MarcParis

6th June 2006, 09:05

Ok thank you for the tip!
It would be easier in fact...:)
Otherwise, do you know the simpliest way to convert audio from my original .mp4 file to AAC LC?
Currently I'm using an avs script to open my mp4 file in virtualdubmod and there I extract a wav file that I convert to AAC lc with nero cli...:):) I'm sure there a quicker way to do it...:)

Then muxed with YAMB, and converted with ATOMCHANGER.
Plays fine on the PC with QT but when placed on the PSP its out of sync, i,am not sure what i have done wrong, as i have been using this for awhile now with FPS as 29.97 and had no problems.
Anyone got an idea whats going on? Thanks.

This is really pi**ing me off now...29.97fps is out of sync now as well.

http://jonny.leffe.dnsalias.com/pmp_mod_avc/index.htm at least we have 480x272 now, still some hurdles to take before we reach full UMD res tough but it progresses nice to see :)
btw did one of yeah heared something about the Author of another ffmpeg decoder based Player called PSPlayer MT, seems he vanished ?

Jonny the PSP optimized ffmpeg h.264 decoder how fast is it compared to Sony's (is it optimized @ all or only ported ? )
BetaBoy allready said that Picard is working on porting CoreAVC to the PSP this could be very interesting in the Future too :)

heres my first test 480x272x24p 788 kbps
http://www.filefactory.com/get/v3/f2.php?f=c411ee

Playback is smooth no problems but the combo 788 kbps avc (deblocking) + 320 kbps mp3 seems to suck on the battery alot

Some chat about the patches with the X264 Devs

(pengvado): x264-info_file.diff: no, I won't allow extra output files. if there isn't any good way to get that info, then write a 10 line C program to grab it directly from avisynth.
(Jarod): how does that help changing .mp4 output?
(pengvado): not at all
(pengvado): I don't see why that patch was written in the first place
(Jarod): to play on the psp?
(Jarod): or should the muxer do it you mean?
(pengvado): x264-info_file.diff doesn't change muxing at all
(Jarod): hmm
(Jarod): so, its useless?
(pengvado): yes
(pengvado): the main patch, x264-pictiming-magik.diff makes the following unacceptable changes:
(pengvado): sets IDR-frames to "low priority" (should be "highest", like it was before)
(pengvado): removes x264's identifacion and settings userdata-sei
(pengvado): and the following errors:
(pengvado): writes low_delay_hrd_flag unconditionally (should appear only when hrd_settings is present)
(CruNcher): pengvado im not sure but maybe that's the way Sony want's the bitstream to be to work on the PSP ?
(Jarod): i doubt that
(pengvado): 4th error: I have to flame the author for calling it x264 v1.0

Bug Reports:
B-frames doesn't work couseing a "avc_get: sceMpegAvcDecode failed" error, but only if --ref is <1 else the decoding of b-frames is out of order seems it displays the encoding order instead of the displaying order (warping)

we are using the psp avc decoding api (the only libavcodec part used is the mp3 decoding now)
at 222mhz, the psp can decode 480x272 @ ~180fps!
(on the player the speed is around 67fps, software mp3 decoding slow down stuffs alot)
probably in successive versions i'll downclock the psp to 111mhz

ffmpeg h264 goes really slow on psp atm (a lot of work would be required to get full speed in software)

interesting infos about bframes (i was assuming bframes totally not working)

about the x264 modifications, my info_file patch is used by my pmp muxer (so it's useful for me and for everyone using the muxer)
the pictiming patch is done by magiK, i don't know 100% the details, but the psp don't decode the stream (or crash) without it (this patch was made analyzing the avc stream inside pmf files and streams produced with the elecard codec)

EDIT:
if some x264 developer is interested, this is the thread where all it's started:

(as you can see, at the start, only the elecard codec was working)

I guess so, but I'm not expert with this license... anyway you've just re-build it and patched it, right? If I'm not wrong the LGPL don't allow you to take portion of code and include them in your own program (but I repeat, I don't have confidence with these stuffs).

GPL => can only be incorporated into other GPL software, any other license must be switched to GPL first.
LGPL => can be incorporated into any software. Technically, it also has to be backward-compatible with itself, to keep apps from breaking if a library is upgraded.

Either way you must supply the source if someone asks (an offsite link is sufficient, or you can just package it too), and the license has to be included with the binary. But that's about it afaik.

I've developed a vlc client called "PMP VLC" for Sony PSP.
(http://forums.ps2dev.org/viewtopic.php?t=6053)

With the app PSP users can view video streams via wlan. The transcoding is done in real-time by vlc 0.8.5 on a PC.

Currently a good quality can be achieved with following transcode params:
Code:

:sout=#transcode{vcodec=DIV3,vb=700,width=360,height=272,fps=25,acodec=mp3,ab=48,channels=2}:duplicate{dst=std{access=http,mux=ogg,url=0.0.0.0:1234}}

Since the PSP can do H264 decoding with dsp hw, I have started doing experiments with x264 (vcodec=h264). However, I have 2 problems:
1. it pushes my AMD 2400 cpu to 100% and the pc is not responsive anymore
2. the only http stream container for h264+mp3 which works seems to be .ts

My questions are therefore:
1. what x264 video encode settings can you recommend to reach a decent quality similar to DIV3@700kbs (360x272, 25fps) and a cpu load well under 100% (e.g. like with DIV3 around 60%)
2. can the ogg container work for http streaming? if not now perhaps in the future? is there another container which may work?

Thx in advance!
===========================
EDIT:
After a long search I found the answers in this thread:

http://forum.doom9.org/showthread.php?t=111925

What do you mean with "http streaming"? I'm not an expert, but I think that you mean progressive download... as long as I know it's not possible to stream over http, you have to use rtsp or something else.
Anyway it's an interesting software, but I canot use it unfortunaltely... you have to use 1.50 firmware, right? and I don't have a wi-fi connection with my PC....

I have tried to use mencoder to encode to PSP/AVC format. The patched MP4 by atomchanger (psp video version) can be played by PSP (firmware 2.6) successfully. But when I seek after 90 seconds of the movie, or fast forward beynond 90 seconds. The playing video cannot be stopped, or cannot play properly.

I have tried additional encoding parameters, such as
bframes=1:frameref=1
bframes=0:frameref=2

The seeking problem is still existing.

I have updated my PSP firmware to 2.80 today (I know, I probably shouldn't have ;-)).
I have tested the video support with the updated version and I found the following:

- Videos can now be placed directly under the "VIDEO" directory of the Memory stick root. (I know, this is part of the official changelog but it's still worth mentioning).

- Videos in the "VIDEO" directory can have any naming you want !!! (no more MAQ*.mp4 naming required !!). However, the title of the video that appears on the PSP is now based on the file name and not on the information inside the file anymore and the thumbnail (.thm file) didn't work anymore in the "VIDEO" directory.

- Atomchanger is not required anymore !! I've been able to create valid files using only megui and avisynth. I've tested with 2 videos (25fps 320x240 with 48kHz sound and 25fps 368x208 with 44kHz sound) and they both worked fine.

- The PSP seems to do a check on the reported Profile/Level. I've found that "Main Profile - Level 2.1" and "Baseline Profile - Level 1.3" worked but I haven't had any success with anything else. By example, "Main Profile - Level 1.3", "Baseline Profile - Level 2.1" or "Main Profile - Unrestricted Level" didn't work.
EDIT: I've done some further testing and it seems some cases that didn't work were because of a problem in my x264 settings at the time of the test. Actually, for the Main Profile, any level set <= 2.1 seems to work. I've tried exactly the same settings (PD-PSP profile from megui) with level set a 1.3, 2, 2.1, 2.2 and Unrestricted. Files with level set at 1.3, 2 and 2.1 worked.

WARNING: These are only my personal findings and if someone could confirm them, it would be good. Since I haven't spent too much time testing, I may have missed some new things and the removed limits may not work in 100% case.

NOTE: I've only tested with files placed in the "VIDEO" directory. I don't know what happens with files in the old directories.

28th July 2006, 20:56

I've done some more testing and I've found another small "hidden" feature:

- Files with .m4v extension works. It seems that files can use either .mp4 or m4v extension.

This may not look very interesting, but the way I found it is much more interesting:

- I've downloaded a few Movie Trailers encoded for the iPod from QuickTime website. I've renamed them .mp4 and simply copied the files on my PSP and they played fine (correct audio/video synchronisation, correct aspect ratio, ...) !!! I then simply tried to keep the original .m4v extension and they worked as well.

Here are some examples I've tried to play on my PSP:
- "Ratatouille" Teaser, 320x132 AVC @ 23.976fps Video, 44100kHz AAC Audio
- "A Scanner Darkly" Trailer, 320x172 AVC @ 24.000fps Video, 44100kHz AAC Audio
You can get both trailers directly from QuickTime website.

It wouldn't surprise me if the compatibility with videos encoded for the iPod was the main reason Sony implemented these new features...
EDIT: Just a note explaining why Sony may have implemented these features: by supporting videos encoded for iPod (as well as removing the file name limits and adding video file saving from RSS... ) this allows the PSP to use most of the already existing video podcasts.

480x272 is not full PSP resolution Display Yes but not full content resolution Studio UMD's are encoded @ DVD Resolution with 1500 kbps, the guy who develops PMP is long time Doom9 Member Jonny hmm you could use XviD4PSP or Mediacoder for easy encoding :)

interesting stuff ghim, im gonna keep messing about with stuff and update my site!

can any psp owners with a dual core cpu get files to play when they select more than one thread? i originally thought it might be my old cpu, p4 3.2HT that was the problem. Sadly, i get the same problem on my dual core centrino, which is a shame as i get much faster speeds with 2 threads.

if anyone could test their dual core setup with their psp, that would be great :)

You don't need a dual core CPU to try the multithread encoding. I've encoded a few files using 2 threads (on my single core CPU) and the PSP can't decode those files.

Files encoded with multiple thread are quite different from files encoded using a single thread (multiple slices per frame if I'm not mistaken).
I know quite a few cases where such files are not supported so it does surprise me that the PSP decoder doesn't support them either.

Ghim

29th July 2006, 11:23

As I mentioned in a previous post, the new 2.80 firmware performs a check on the H.264 Level reported in the H.264 bitstream. For Main Profile, all levels > 2.1 are rejected.

This new limitation is not a problem for reading newly encoded videos or videos that were aready using a correct level.

However, I've just found out that the PSP videos that can be downloaded from "Google Video" website reports a level of 5.1 and are rejected by the PSP.

NOTE: I've only tried with videos in the "VIDEO" directory of the root. I haven't used the old file naming (old directories and file naming) since I've updated to 2.80 so I don't know if videos using the old naming are affected by these changes.

I have some AVC files encoded by myself which work under the MP_ROOT folder. I have installed 2.80, and now when I put them under the "VIDEO" folder, they don't play anymore. I guess the H.264 level reported by my AVC files is unsupported by PSP under the "VIDEO" folder... as mentioned by Ghim.

Is there any way to edit the header of an AVC file to change the reported H.264 level....? I want to make my old AVC files work under the "VIDEO" folder, since I want to include them in my RSS Channel... and they have to be in the "VIDEO" folder.

Hello all,
Just wondering if anyone else has the same problem.
Ive updated to v2.80 and have encoded some PAL video (am in Ireland) but although it plays ok, the video is kind of jerky.
Its as if it plays ok for 20 frames of the 25 but the last 5 frames kind of speed up.
Some im thinking, is it the psp hardware actually decodes the video framerate, as in its in built, but the firmware merely tries to correct the hardware on a software level. Anybody have any thoughts??

I currently now use Xvid4PSP as am encoding PMP,s, but oddly enough MeGUI and X264 encodes look better (not res wise) most if all the ghosting have been cut out as well as the halo you get from red colours.
If only the PMP container was added to MeGUI, along with Jonnys modified version of x264, you would be making truly remarkable encodes.

foxyshadis

7th August 2006, 20:26

I'd like a little more information on this:

1. What is PMP exactly, and how does it compare to MP4? Or is it based on another container?
2. What can you mux from to get PMP? MP4? Raw? With what tools?
3. What modifications were made to x264? MeGUI will never package an x264 that breaks something, but if it's just a PMP output module, you could probably send to sharktooth for inclusion in his builds.

8th August 2006, 14:35

I've read the H.264 standard and it should be possible to do. However, I don't know any tool available at the moment to do it.

I have finally figured out a way to modify the AVC level so that PSP can recognize it under the "VIDEO" folder :D

After some searchings on the Interent, I know that the AVC profile/level information is stored in something called "profile-level-id", a 3-byte header which stores the information in the format of

profile(1 byte):constraint flags(1 byte):level(1 byte)

I don't know much about "constraint flags", but it appears to be usually "00". So for a AVC Main Profile Level 5.1 file (encoded with x264), the "profile-level-id" should be

4D0033

What you need to do is search for this hex value and replace them with

4D0015

which changes the level from 5.1 to 2.1.

I tried this on some of my previously encoded (x264) AVC videos, as well as a few Google AVC vidoes, and after the changes, they all played in "Video" folder on PSP.

Note that this header is either at the beginning or at the end of the AVC file, and it appears TWICE nearby (I change both).

CruNcher

8th August 2006, 15:58

its not hard to integrate into Megui you can do it by yourselves by useing profiles and the custom command in Megui very easy stuff but you have to keep the x264 patched all the time and with the rapid development of x264 the patch becomes fast invalid and needs to be reworked also pengvado doesn't like what it does with the stream he allready said in its current state he wont bring it in the rep.

I have read this entire thread, tried numerous settings on my own, and have finally given up hope of doing this without help. Every video I create with x264 that is listed correctly in the PSP displays the message "This video cannot be played." when I try to play it.

1. In firmware 2.80, I make a folder called "VIDEO" in:
a.) the root of the memory stick?
b.) the MP_ROOT directory of the memory stick?
c.) or the PSP directory of the memory stick?

2. A file name like "Invader Zim.mp4" is allowed in that folder, right?

3. What is the maximum total bitrate (video + audio) allowed for an x264 created video on the PSP with firmware 2.80?

*3. Could someone please post their entire PD-PSP profile that has been CONFIRMED to work in firmware 2.80?

Thank you guys sooo much!

*Extremely important, because the latest PD-PSP profile has a few settings set that are confimed not to work on the PSP. God knows what other settings are incorrect.

To answer your questions:
1.)
a)Yes, you do create the VIDEO folder in the root of your memory stick

2.) That filename should be allowed, yes.
3.) Videos in the VIDEO folder must be no more than Level 2.1@Main profile or the PSP will not play them. I don't think there is an audio bitrate limitation, however.

Here are the x264 two profiles I use along with two nero aac profiles:

According to Sony's official specifications for the VIDEO folder, the maximum video bitrate is 768kbps and the maximum audio bitrate is 128kbps (I haven't tested however so I don't know if higher bitrates are rejected or not).

If you can read Japanese, here is the link describing the exact features:
http://www.jp.playstation.com/psp/pdf/RSSChannel-J_2.80.pdf (The Appendix is the most interesting part for the supported Video and Audio)

For my x264 profile, I use the PD-PSP with only 3 modifications compared to the default version:
- level set to 2.1 (instead of Unrestricted)
- B-frames set to 1
- Number of Reference Frames set to 1

I did a quick test now using x264 ABR 768 Kb/s & nero aac at q=1 (~400+ Kb/s), and it played fine on my psp, so i guess there isn't an audio bitrate limitation.

The zip file seems to be corrupt. The audio profiles extract fine, but the video profiles do not.

For my x264 profile, I use the PD-PSP with only 3 modifications compared to the default version:
- level set to 2.1 (instead of Unrestricted)
- B-frames set to 1
- Number of Reference Frames set to 1

I closed MeGUI completely, downloaded the profiles from http://mirror05.x264.nl/Sharktooth/?dir=./MeGUI/profiles, overwrited the PD-PSP profile to get back to the defaults, changed to level 2.1, B-frames to 1, reference frames to 1, Bitrate to 384, and VBV Maximum Bitrate to 768.

Here is my AVISynth script:

DGDecode_mpeg2source("blah blah blah.d2v",info=3)
ColorMatrix(hints=true)
tfm().tdecimate(mode=1,hybrid=3)
Crop(6,0,-6,0)
Undot()
LanczosResize(320,240)

Here are my Nero Digital AAC settings:
_ Force Decoding via DirectShow
Output Channels: Keep Original Channels
X Increase Volume Automatically
X Improve Accuracy using 32bit & Float computations
_ Delay Correction
X Constant Bitrate @ 128kbit/s
AAC Profile: AAC-LC
_ Create hint track (for streaming server)

I hit AutoEncode, select Average Bitrate to 384 kbit/s, click Queue, then start the queue. The video ends up being 320x240 at 23.98fps with 48000Hz Stereo.

"This video cannot be played."

Umm, just a thought but how many threads is your Megui set to use? If your machine is dual processor/multi core/hyperthreaded the encode will not work. You must set Megui to use only one thread. Good luck mate.

Hi everybody,

(Clown shoes no news about HD DVD...)
I have a PSP and a LocationFree Box. The last firmware, 2.8, of PSP
can play AVC but with some restrictions.

I test lot of options, there is a big restriction no more than one "Slice".
The resolution is locked at 320x240 :mad:
The bitrate can be ABR, VBR and CBR ( up to 4000Kbps !!! :eek: ).
PSP support all bitrate between 50kbps to 4000kbps

All Google video for PSP are encoded by x264 with VLC program !!!!!
And the manual hex patch (4D0033 replace by 4D0015) work fine on PSP :p

Nobody know how I can read the LocationFree video stream
with other player than Sony software player on PSP or on PC
(LocationFree Box is a realtime hardware video stream
in Xvid, ???, -> I see TV channel from my home DVB receiver on my PSP
in my home or in my work via web connection with Wifi :D ).

does megui have "automatically set number of threads" ticked in settings? if so, it will over ride your selection of 1 thread and will make the video not work.

Ghim, can i pick your brains mate?
I did what you said about using the default PD-PSP profile and then changing the three settings, ie the restriction level to 2.1, b-frames set to 1 and ref frames set to 1.
Except when the video is encoded, the bitrate is too high. Roughly about 1300kbps. Ive changed the bitrate to 384 and the vbv max bitrate to 768 but still its too high. Did you have any problems with this?
Id appreciate your help cos im close to pulling my hair out!! :angry:

Ghim

13th August 2006, 21:06

I've never had such a problem.

For the VBV Max Bitrate, I'm using the default setting of the PD-PSP profile (4000) and for the bitrate I'm using 500kbps.

After encoding, I get exactly what I asked for (500kbps).

How do you start your encoding ?
Do you use the "AutoEncode" button ? If that's the case, make sure you set the "Size and Bitrate" setting to "No Target Size".

13th August 2006, 21:59

Any chance you could post that profile Ghim?
Ive tried that and still getting to high a bitrate. Ive changed the bitrate to 768 which is what i want and the strange thing is the video will play if i put it in the VIDEO folder but i dont want so high a bitrate. It still exports the video at about 50meg for a three minute clip!! What the heck am i doing wrong?!!

PSP can read AMR, AAC LC and AAC HE audio (on MP4 or 3GP container)

Lot of options of H264 are accepted:
Weighed Prediction, Half Pixel, Chroma ME, Quarter Pixel, Partitions.

GOP up to 30 frames (I don't test more)

I only purchased a PSP recently, primarily to play videos. I am not a gamer. Firmeware is 2.0.

Searching around the first choice to convert videos I found was PSPVideo9. It's pretty much plug and play and getting TV shows or DVD's onto the PSP was pretty easy. I am encoding in AVC format.

But I am finding that the shows I encode (versus the one UMD I have) have annoying red blotches occuring in dark areas (like in the open mouth of somebody) plus some smearing. I think the smearing is a hardware limitation but the red blotches are probably not.

I have gone through this entire thread and while I understand most of it, I am wondering does the use of X264 plus various audio encoding techniques (which are of course not relevant to the video problem) create an improved picture? Can you get rid of those red blotches?

Sorry if these questions seem simple but I just could not find an answer reading the thread.

As as aside I tried to use belite to encode audio and it failed looking for a coupole of aac DLL's which I cannot find. I presume they are the Nero AAC pack which you have to purchase? I did find an AAC plugin for Adobe Audition (which I do have) and while that's not a CLI solution, at least I can take the extracted wav file from the video and encode that in PSP compliant AAC format (I hope!)

Thanks for any assistance

Well nobody replied but I managed to solve the problem myself :)

As usual it was the audio which was the problem. I had tried faac, belight and even neraacenc but for some reason could not generate a compatible audio file. In the end used the plugin for Adobe Audition and created an aac file that was compatible and when muxed with the video created with x264 made playable mp4 files. The additional avisynth filter also has removed the red splotches which is godsend. The additional effort over using PSPVideo9 is worth the removal of those things which were quite distracting.

Having to use Audition means it can't all be done in batch but at least it works

If somebody can provide a command line sequence for neroaacenc that works or even faac I would be grateful

Making good progress on using x264 and mp4box to create video for the PSP. Have gotten to the point where I can convert divx and DVD fine. And thanks to a hint from Deeks, have reduced the red splotch problem.

In an earlier post somebody talked about the problem where there are sticky frames - 2 frames skipped just before an I-frame. I think I see this manifest itself as jumpy video every now and then. Interestingly it occurs both on converted PAL DVD and NTSC divx.

Reading through this thread it seems the only way to fix this is to upgrade to 2.8 firmware which allows different framerates to be played? Is this correct? I am on 2.0 but would happily upgrade to 2.8 if that fixed the problem.

Just going back to what you were saying about the ghosting.
I had the same problem too but apparently, according to sony, the ghosting will occurr when the psp just starts up and you have to give the components a chance to heat up in order for the video to play ok.
I tried this and it does work. I let the video play for about 45 minutes and it seemed fine.
Anyway just to let you know in case you continue to pull your hair out trying to figure it out, like me!! :D

Hi

The ghosting is pretty minimal now and I really happy with applying the avisynth filter that the red blotches are also gone.

When I get the chance I plan to upgrade to firmware 2.8 and see if that can get rid of the sticky frame problem

I had a shot at encoding a movie at 23.98. Source is NTSC xvid. Changed the mp4box command to -fps 23.98 and removed the ChangeFPS(29.97) in the avisynth script. Movie encoded okay and plays fine in QT which shows the rate as being 23.98. Of course, can't check if it will play in the PSP until I upgrade the firmware :)

Anything that plays on 2.0 will surely play on 2.8 as well, as long as you put the movies in the old folder structure.

If you want to put them in the new "VIDEO" folder, you may need some simple header changes.

Thx, but that works for videos in the MPROOT/ directories. I have another problem. I put standard .mp4 files in the root [VIDEO] directory (new possibility of firmware 2.8). The megui encoded video work fine but I'm searching for the trick to tell the PSP there's a thumnail associated with VIDEO/video.mp4. I tried with a 160x120 jpeg file (e.g. VIDEO/video.jpg) with the same name as the .mp4 but no succes.

If I run atomchanger on the standard .mp4, I can have thumnails but some bug makes that the video stops a few seconds before the end while audio continues (for long videos and when no fast forward/backward is performed, just playback) :( . The standard .mp4 in [VIDEO] works fine.

26th August 2006, 07:09

Still on firmware 2.0 since I want to make sure all is well before upgrading. Can't use megui since this requires .net 2.0 and the machine is a bit flaky for that.

Anyway have been successfully converting files fine using x264 and Adobe Audition with aac plugin.

Decided to get belight a whirl since it looked less of a hassle. So the process is

1. encode video with x264
2. create wav file from original video
3. encode wav file in MP4 file (AAC on the container) using belight and Nero Digital
4. Mux the files together with mp4box

The resulting mp4 file plays fine using QT. But to get it to a compatible PSP format I have to run atomchanger.

This works well for files created in my usual process, but once the MP4 created from mp4box is processed by atomchanger, the resulting file loses audio after about 1 minute (both on QT and in the PSP) and eventually the PSP notes the file is invalid.

This is all that's in my atomavc.ini file

I used Atomchanger from http://www.bontragerphotography.com/psp/ for processing 25fps video and 44KHz audio encoding. A small video of five minutes plays fine (if number of ref frames = 1 and number of B-frames = 1) under firmware 2.8. The strange thing I encountered is with longer sequences (15 and 25 minutes). The video freezes just before the end while the audio continues. I also tried with PSPvideo9 Atomchanger and the same bug (??) happened. Remark that when during playback, the movie is fast forwarded, backwinded or paused, the movie plays correctly until the end. As a result, I now put the megui standard mp4 file in the VIDEO directory where they play fine. Therefore I suspect some bug is triggered in playback on PSP with firmware 2.8 is current Atomchanger if used. I will try 48KHz instead of 44KHz aac-lc, maybe that will circumvent the bug?

you using the recompiled atomchanger from my site?

why not just make your life so much easier and upgrade to 2.80 :) i personally would strongly reccomend it if your going to be using video, AAC HE+ps is ideal for the PSP when file size is so important. and somehow get net 2.0 working, megui is the PSP owners best friend :P

I am using the unrestricted atomchanger. Can't work out why the process of applying atomchanger breaks the audio since the file after muxing is fine. I should upgrade to 2.8 at some time. I just want to find out why this process is not working.

As for .net 2.0 - well might have to bite that bullet also :(

I wouldnt upgrade, i would downgrade, currently i,am playing 480x272 AVC movies on my 1.50, (which i downgraded from 2.60) and i can tell you this, you,ll not get better on 2.80, infact you,ll not get better until Sony takes the res restrictions off its player.

How do play 480x272 movies? Sounds like you have to use a different player? I am reasonably happy with PQ on the PSP. It's not my main video platform or course - just for when I am in the mall waiting for the wife or waiting for the kids during their various lessons :) Also for when I travel on planes (assuming these days I could take it on the plane!)

But would like the sticky frame problem fixed which I understand was fixed in 2.5?

Thats right mate, its a third party player for a 1.50 PSP called PMPMOD AVC http://jonny.leffe.dnsalias.com/pmp_mod_avc/index.htm
The native player on the PSP has restrictions on the resolution, no more than 76000 pixels (around that), now with PMPMOD AVC you can play 480x272 res movies which works out at 130560 pixels and looks super sharp.
I did use MeGUI but when i downgraded it was of no use, as you need a modified version of X264 to encode which is also available from the same site.
So which would you rather? 76000 or 130560...not much of a contest is it? :)

Well solved the problem sort of. Encoded the mp4 file using neroaacenc instead of belight and the Nero DLL's and the audio is fine on the PSP. The only annoying factor is, the wav file that neroaacenc needs to be processed has to be completely uncompressed - it won't read a wav file with MP3 or other internal formats. So that's another step in the process.

2.8 is looking more attractive :)

From what I have read downgrading from 2.0 to 1.5 if not done properly can render your PSP a brick (is that the term?). I guess I don't quite have the nerve to do that quite yet :(

HI, I just downgraded from 2.71 and first thing to try was PMP AVC. I have to admit its really nice piece of homebrew and it works fine. I would like to ask, what possible features of h264 can be set for this. I just tried my ordinary profiles in Megui (using modified x264 of course) and it didnt work, then tried the examples on the homepage and they expextedly did work. But they are pretty simple...I was wondering if it wouldnt be able to cope with other features of x264 (at least some of them). I would like to know which ones....the example megui profile would be the best. Thanks a lot and also my big thaks to the creators of PMP AVC.

jonny

6th September 2006, 09:55

@gabbon:

Main profile, level 3, no bframes.
Every option trigging an higher profile will not work.
Also using more than one encoding thread break compatibility (in this case frames are divided in slices and this is not supported).
We are using the internal psp decoder and there are no rooms for improvements (the only thing that could be still added is a limited bframes support)

gabbon

@Jonny

Doesnt really matter anymore, I tried 2-pass 768kBit/s with few sample anime episodes and it looks absolutelly marveluos even without other features - nothing to improve :). Compared to my old encodes in 368*208 its much sharper (well that was to be expected) but even more importantly no "fucked up edges of red/crimson objects" (probably present thanks to "ingenius" PSP resizing filter)!!! So I am more than satisfied now.
Thx a lot for this very useful program :thanks:

VobSub() and TextSub(), both part of VSFilter, which can be loaded into avisynth as a plugin.

"avis [error]: unsupported input format (DIB )

My aviscript looks like this:

DIB is not wrong colorspace, it's the avisynth error colorspace. Changing the colorspace won't help. You always have to load it into virtualdub and see what error shows up, until x264 gets avisynth error handling. (On the todo list.)

I'm kinda late to this thread, but I've been having some issues encoding in AVC for my PSP. I've used the PD-PSP profile and made the necessary changes to it to make it compatible with the PSP. (main profile 2.1, 1 bframe, 1 reference frame) I've also unchecked the option to have megui automatically control the amount of threads during encode. Now here's my problem. I'm able to make an encode of a 5 minute video clip work on the PSP. But when using the exact same settings, an encode of an hour-long video gives me the "unsupported format" message, and is unplayable on the PSP. I'm using firmware 2.81 and have been placing the videos in a "VIDEO" folder on the root of the memory stick. Like I said, shorter video clips seem to work, while longer ones fail, even at the same settings.

Hmm, I don't think it's the audio settings, cause I can play the audio if I put it in the music folder. But I use Besweet with the Nero AAC encoder, using LC AAC at 96kbps. The weird thing is, a short 5 minute video clip will work, while a longer 1 hour video clip won't even be recognized as a playable format by the PSP, using the same settings. It will only show that "broken" thumbnail, saying it is an unrecognized format. That's really what's bothering me.

Oh, and by the way, how would I go about making an Xvid file compliant for the PSP. I tried making one, and while the PSP would show it in the video tab, it would tell me that the file couldn't be played when I select it. I'm suspecting that I need to set the profile to simple in the config settings, but I can't find where to do that in megui.

Question, has support for higher resolutions been added to newer firmware (2.80+)?

Aside from homebrew programs, has anyone been able to create full resolution video playable on the PSP using x264?

This might be a bit off-topic but still of interest.

My brother has a Japanese PSP and I was able to use the P-TV service to download a couple of free (albeit DRMed) clips. It was saved in \MPE_ROOT\100AEV01\ with a .MGV extension and is accompanied by a license file. File naming is the same as for AVC pre-fw 2.80 (e.g. MAQ12345).

Here are the details for one of the clips.

Self-synchronizedIt would seem that the thumbnail is embedded the clip. I wasn't able to play the video nor audio, although I was able to extract both using Yamb. Playing both the original and extracted clips with MPC and ffdshow just gave me an error. With VLC, it shows the time and the bar moves but I don't see or hear anything.

While the clip is reported as 480x270, I'm not sure if it's all that accurate. Although, assuming a macroblock size of 16x16, it would still fall well within the boundaries of Main Profile @ Level 2.1. The PSP reported it to have a video bitrate of 1000kbps and an audio bitrate of 128kbps. It might be interesting to note that the video also played on my US PSP when I put in my brother's memory stick, although it did ask me to set the time using "Set via internet" option. I haven't yet tried transferring the clip to a different memory stick and playing it from there.

full res video is available since 2.8 with
Video: MJPEG
Audio:LPCM or μ-Law
in standard avi container.
no fps, sample rate, bitrate limitations so far.

place the file in VIDEO folder and you can play it from video menu.

also notice that VIDEO folder can accept standard MP4 files, no need to change the header, or rename the file to some special name anymore.

full res video in SP and AVC might be open to user in future according to software development director.

18th December 2006, 21:53

How do you encode MPEG-4 SP instead of AVC with x264? Or better yet, are there any megui profiles for SP that works on the PSP? I know Sharktooth created the PD-PSP profile and that works GREAT for me, but I can't seem to figure out a way to create a proper SP encode w/o the PSP telling me it's unsupported.

If you guys have any profiles I could grab, I'd really appreciate it:)

P.S. It's for anime...

Sudds

18th December 2006, 23:07

Why do you want to encode to MPEG4-SP?
MPEG4-AVC is a much better codec, quality and compression wise.

foxyshadis

18th December 2006, 23:38

If you want SP, you'd use an (A)SP codec! Xvid, nero digital, divx, take your pick, but not x264 and not this forum.

I'd also assume you'd want to use the best codec that works. Is it a battery life issue, or something?

nahpxela

19th December 2006, 01:04

Well, I'm just encoding for someone else and they don't want the high quality. In this case though, the main reason is that the source is at 24000hz, and when *I* tried to convert it to 48000hz (I don't know anything technical so I tried it), the sound was all sped up. I'm assuming I can't do that so I'm forced to stick with 24000hz.

From what I read, SP and AVC requires 24000hz and 48000hz audio, respectively. Feel free to correct me if I'm wrong:) The source isn't all that great anyways, but people can't really complain about quality when it's free for them:p

And no, not necessarily has to be the best codec, but knowing which one is (isn't asking for the "best" on here not allowed? :p) wouldn't hurt. Whichever one that will encode SP (PSP doesn't support ASP does it?) that will work on the PSP and ipods will do.

Thanks for the info so far!

Edit: Trying out PSPenc...but if there's any additional sources I should read up on, please let me know:p

I've read this thread in it's entirety and I'm still having trouble. The only way I've gotten video to work on my PSP is by using PSPVideo9 (uses ffmpeg). I would prefer to use MeGui like I do for everything else. I keep getting "Unsupported Data" errors. I used the PD-PSP profile (even tried with Threads=1 instead of auto) and used nero cli to create my audio (naac.exe -he -q 0.15 -if "POTC T01 3_2ch 448Kbps DELAY -227ms.wav" -of POTC.mp4), still no luck. I keep seeing that people are getting their stuff to work but no go for me. I have a PSP that cannot be homebrewed (TA-082 or whatever) and I have fw 3.02. Is there a page that lists some common "gotchas" or something for me to start with?

Maybe I should add more...I have been taking my DVD->MKV Avisynth script which looks like this:

MPEG2Source("POTC.d2v", info=3)
ColorMatrix(hints=true)
Crop(0,60,0,-66)
LanczosResize(720,288)

and just use the "convert.bat" that I found in this thread (modified a bit). I pass this avisynth script in and it does the rest creating a new AVS, then I feed this into avisynth, I've even done the command line stuff from the batch file but no luck.

well 2.71 cant handle 25fps, only 2.80 onwards.

so if your source material is pal DVD then you will either need to change the fps of your audio and video or update to a newer firmware.

if your source is 23.97 or 29 then try a profile from my site and see what that does.
unfortunately not work for me.I have try also 29.970 fps, but not work.My source is Avi/Divx 25fps.
I have also followed your guide,(assume 24fps etc.) but not work.
Only soundtouch/Tempo correction with Belight work, but during the seeking all go outsync
anyway thanks...

hmm, i can't get my psp to detect any videos at all in my 'VIDEO' folder, with my psp saying "There are no videos." i'm not sure if that's because of an encoding issue, or something else.

i've tried encoding videos at various bitrates from 300 to 700, trying different fourcc codes, turning turbo on/off, multithreading on/off..but no luck. i've also tried using deets' profiles, as well as modifying the regular PD-PSP profile.

currently, my encoded video is at 320x240, 23.976 fps, ~300 kbps, with aac-lc audio at 48 khz and ~107 kbps. as far as i know, with firmwares 2.80+ (i'm on 3.03), the filename does not matter, and all you need is to place it in a 'VIDEO' folder within the 'PSP' folder.

any help would be greatly appreciated.

Here's an interesting post on PSP Fanboy: Downloading free hi-res videos from P-TV (http://www.pspfanboy.com/2007/01/04/downloading-free-hi-res-videos-from-p-tv/)

Apparently there's a Japanese site (P-TV (http://www.p-tv.jp/genre.cgi?genre=ct11)) where you can download videos for the PSP and they use the full resolution.

Perhaps there's a way someone can try to download one or some of the free 16x9 videos (they have ones you can pay for and ones you can buy) and try to figure out how they're encoding them or what magic bits they're adding.

It sounds like they're DRM'd though as the videos expire after 7 days.

Edit: OK I tried it out. Not only does it do fullscreen video but there's also video thumbnails! Here's a MediaInfo dump from the video file:

Hmm maybe we can add thumbnails to the video by adding an MJPEG stream with proper dimensions into the MP4 container? This is looking exciting :)

CruNcher

5th January 2007, 06:12

Jep that could work (excited) but the other question is will the Sony Parser accept it in .mp4 as it does for .mgv and also from the normal VIDEO dir or only MPE_ROOT, if yes this has a very good chance to work (without firmware modification) the video thumbnail part at least, still we have to find out where the mechanisms inside the PSP firmware are that controll the 320x240/368x208 (pixel limit and final bitrate restriction) for the XMB, but also that is just a matter of time, thx Schrade for that really interesting info on the Online Content we all slowly get behind how Sony restricted the PSP for their own good :)

Incidentally, they have a site set up on P-TV specifically for the PSP. Rather than using IE to download the file, I just loaded up their PSP website (http://www.p-tv.jp/psp/) and downloaded via that. The menus were switched to dropdown menus but studying the characters in the pictures it was easy to match them up and download the content directly via the PSP's web browser.

I've downloaded both 16:9 and 4:3 videos from that site now and ran MediaInfo on them. I've put the 16:9 video dump above, so here's the 4:3 video here:

Notice how they're keeping the aspect ratio at 16/9 and using black bars for the 4:3 content? Also take note that all vertical resolutions are 270. (3 out of the 3 videos I downloaded had this..)

So I wonder if just making a video with 480x270 dimensions will work? Just guessing though.. I don't know much about how the PSP's firmware is restricting it.

I am sorry, but isn't it known already that you can go full res on a PSP using MJPEG? http://pspupdates.qj.net/2-80-plays-480x272-if-it-s-Motion-JPEG/pg/49/aid/72373

Edit: Or http://forum.doom9.org/showthread.php?p=906603#post906603

Yes, it's very well known. We're talking about full res AVC though, as this is in the MPEG-4 AVC forum in a thread about the same thing for PSP. The MJPEG referenced in my posts are for the thumbnail that shows up in the Video Cross Media Bar menu.

CruNcher

5th January 2007, 20:34

Some tip if you wan't to have thumbnails for folders in the Music dir you can just use a normal thumbnail as for videos just put it in the dir of the Album, but the dimensions have to be a little smaller i think (not sure tough) im searching for alot of such stuff, gonna publish everything soon what i found, im not @ home currently. Their are actually 3 pictures you can use 1. The Folder Picture (smallest) 2. The Properties Info Picture (little bigger) and 3rd the Cover in the Player Picture.

I've downloaded one of those video files from the www.p-tv.jp site. One of the things I noticed right after the file finished was a screen that said "downloading license file". So it seems to me that a license is required to play the file...I've attached the file, it's binary with a few strings that you can recognize...I'll play with it and see what I can make happen.

Some good news guys for those running DA custom firmware..3.03 OE-B will be able to play 480x272 resolution from its native player!
Happy Days are here! (soon) :D

Ok, I just got it and I cannot play the new 480x272 files I created. I used the same x264 options I used for the regular 368x208 but no cigar... I will try to lower the number of bframes and ref frames next...

Edit: Still no success using x264, but the files produced by the 3gp converted (using the profiles of the readme 303oeb) do work! Too bad they only have these settings

11th January 2007, 03:17

Well I managed to get it WORKING.

Use the regular options for 368*208.

Here's me settings copied from MeGUI,

--crf 20 --level 2.1 --ref 2 --mixed-refs --no-fast-pskip --bframes 1 --b-rdo --bime --weightb --direct auto --filter -1,-1 --subme 7 --trellis 2 --analyse p8x8,b8x8,i4x4,p4x4 --me umh --threads auto --thread-input --progress --no-psnr --no-ssim --output "E:\Video\Movies\English\Clerks.2[2006]DvDrip[Eng]-aXXo\scriptv.mp4" "E:\Video\Movies\English\Clerks.2[2006]DvDrip[Eng]-aXXo\script.avs"

But the audio needs to be AAC LC (like those in Firmware 2.71).

LASTLY, the resulting file needs to be atomchanged then renamed to MAQXXXXX.MP4. You have to use the atomchanger that supports all fps....Atomchange will automatically renamed it to MAQXXXXX.MP4

Then put in the previous (2.71 and below) folder structure MS:\MP_ROOT\101ANV01.

You can also use the .THM thumbnail file this time.

I tried with 29.90 fps and 23.976 fps video...I'll try a 25 fps video later.

Well, Thanks D_A.....if he ever reads this post is...

Hope this helps all the 3.03 OE-B out there...

I think what he meant was the pain of the stupid atom changing, filename naming and thumbnail generating.

I'm currently trying to track down how P-TV does their thing.

Apparently, they are using Sony Image Converter 2 Plus to create 480x270 MPEG4-AVC videos and then adding DRM to them (and also the MJPEG thumbnail contained in the .mp4 container)

Notice that the videos from P-TV match the specs listed here:

http://www.memorystick.com/en/ms/variety1.html#avc

(768kbps/1000kbps, 480x270, 30fps)

Anyone have a Sony VAIO Computer? It seems some of them shipped with Image Converter 2 on their discs so you could give it a try.

Just updated and tested it. Only plays from the \MP_ROOT\101ANV01\ folder and you have to use the crappy MAQxxxxx.MP4/MAQxxxxx.THM again. Oh well.. cool deal to be able to do it at least.

One more thing.. madruscoe has released a modified PMP Mod AVC that has lots of additional features and tweaks to it.

Im sucessefully encoded 480x272 mp4 files, which are playable at 3.03 OE-B firmware, thanks to info in this thread. But when Im trying to encode some 4:3 AR videos into 368x272 files, they played on PSP stretched out to 16:9 (however, on PC its all right). And AR switching into PSP doing nothing at all.
Am I totally wrong with 368x272 resolution? Or maybe final AR depends on some headers, which PSP reads differently from PC?
Does Atomchanger write videoAR flags?

(Im encoding clips with x264 into MP4, muxing with MP4Box then Atomchange. All resizing done inside AVS script.)

Yes, files would need to use the old naming pattern. Yes, you can use a different player provided your PSP is homebrew-capable. It only supports MPEG4 AVC at full res, Dark_Alex didn't bother modifying the MPEG4 SP profile since "AVC is better", from the readme, not mine.

Dark_AleX does it again. He has released another version of his custom firmware, 3.03 OE-C.

This time he's unlocked the bitrate of the videos. He's raised the max bitrate to 16384 Kbps. That's just what he set it to as the max and it goes along well with his previous 3.03 OE-B release of unlocking the resolution of videos.

AR not use the encoding
Directly Resize（368x272）
Then when the playback Adjusted original mode Can
After test,3.03oec 64x64 from the Minimum To 480x272 maximum,Middle original mode can be used as long as mod16
(For example : 352x64,64x144,……)
If the output encoding into 480x272 adding "--sar 1:1 "
Will be playback shielding zoom, fullscreen, normal, Only original 4:3 two mode

However, I have some doubts, which in the end can do anamorphic psp playback???
Have done precise 320x240 to 426x240, it can playback on the psp, But there has been no adjustment to the primitive 426x240

I'm guessing the problem is with the audio. For some reason, your output file has a sample rate of 32000. MPEG4 AVC profile for PSP requires 48000. Maybe you can try a different audio encoder such as Nero or even iTunes?

I'm a newbie at this. Is x264 the "best" AVC codec to encode with right now? Which GUI can I pair with x264 to encode to 480x272 which is the native resolution of the PSP.

Since DVD's natural resolution is 720x480, can I just downsize the DVD's resolution to 480x272 with no loss in aspect ratio? Or I'm going to have to use a different resolution and not achieve a full screen playback? Thanks!

ilovejedd

20th February 2007, 13:54

What other free AVC encoders are available? Even ffmpeg uses x264. I haven't used any GUIs for x264 as I find ffmpeg much easier for this job (built-in atomchanger) but I think MeGUI's recommended by most.

It really depends on your DVD. Even if the resolution for the VOB files is 720x480, actual content can be different aspect ratios. Some examples:

Package Label: Widescreen 1.85
VOB resolution: 720x480, letterboxed
AR signal: 4:3

Package Label: Enhanced Widescreen 1.85
VOB resolution: 720x480
AR signal: 16:9

Package Label: Widescreen 2.35
VOB resolution: 720x480, letterboxed
AR signal: 16:9

For the first example, you have to crop the black bars first then resize to 480x272. For the second example, you can go straight ahead to resizing to 480x272. For the third example, you can also go straight ahead to resizing to 480x272 but encoding the black bars is a waste so you might want to crop it first then resize (480x204) or resize (480x272) then crop (480x204).

Is this the "best" setting for to obtain the "best" video quality for MP4 downloads? I have a 4GB memory stick duo pro and my PSP is flashed with Dark Alex's custom firmware. My goal right now is to find the ideal settings for the best encodes. File sizes are obviously important too and I want a right balance with a tilt towards video quality.

22nd February 2007, 10:40

Certainly not the best (closer to worst) since ffmpeg's default x264 settings are bad for this purpose. There is a good ffmpeg-x264 encoding guide by Robert Swain here: http://rob.opendot.cl/index.php/useful-stuff/ffmpeg-x264-encoding-guide/ (and more discussion about it on a doom9 thread (http://forum.doom9.org/showthread.php?t=121429)).

The PSP part of the guide is not yet finished, but you should be able to find out about the restrictions elsewhere (like the MeGUI profile) and apply them to the parameters.

Bitrate and resolution might be hacked but the rest still applies. Also, I'm not sure if the PSP can work with VBR audio. I think I read somewhere that it doesn't, or at the very least, it's problematic.

There are already several HQ PSP profiles available. All you have to do is change the resolution in the profiles to 480x272 and bitrate to whatever you want and you're set. Keep in mind that the additional options are there to compensate for limitations in bitrate so if you throw enough bitrate at it, even the base x264 settings of ffmpeg will be suffice.

Not everyone is comfortable using hacked firmware. Most will still use official firmware from Sony (although, imho, they're missing out a lot with regards to the PS1 emu ;)) so you can't expect the guide to cater solely to those using hacked firmware. Besides, you can still use the options detailed in the guide, you just don't have the same limitations when it comes to resolution, bitrate and x264 profile level.

For better control use x264, a separate AAC encoder, mp4box and AtomChanger. There are numerous guides on this thread alone. I just use ffmpeg because its built-in AtomChanger for encoding PSP videos is just so darned convenient. Not to mention it's akin to a SwissKnife for media transcoding.

Currently, I prefer PMPModAVC to the Sony player. I can use x264 level 3 encoding at any bitrate, and VBR mp3 for the audio.
In Dark_Alex's 3.10 OE-A' (AKA OE-A2) he has unlocked the bitrate as well so there's no worry in that.

I prefer having AAC as the audio too vs. MP3.

Currently the only reason I can see to use PMPModAVC is if you want Subtitles, want more battery conservation or if you already have pre-encoded movies.

Well, one issue is that even though you are now allowed to use full resolution, if you do, it won't start in full-screen mode. Second, it's a pain doing multiple audio tracks with most PSP MP4 converters. PMPMod(AVC) starts in full-screen mode, and multiple audio tracks are as simple as just adding more mp3s in the muxer. Also, I think that VBR MP3 sounds better than CBR AAC.

But, everyone has their own preference, which is why the lastest custom firmware is so nice - you can make full resolution videos with >768 kbps for the XMB now, whereas before you were STUCK with PMPMod(AVC) if you wanted that, whether you liked it or not.

MediaCoder now supports producing both PSP and PMP MOD files with x264. Instead of using AVS, MediaCoder retrieves yv12 data from MPlayer via a pipe and feed x264 via stdin. Besides encoding, MediaCoder generates thumbnail and can automatically transfer encoded files to PSP.

There has got to be a way to get it working. If you go back several posts in this thread you'll see me talking about P-TV and how the videos there have their thumbnails embedded in their MP4 container as a JPEG image. I muxed a JPEG image into a plain mp4 video but it wasn't picked up in the Video folder. It might just be an Atom thing though and we just have to find out if it needs a specific Atom on it for it to show up as a thumbnail.

Thumbnails are 160x120 JPEG files with a .THM extension. It's usable with the original folder method. The thumbnail must be in the same folder as the video and must have the same (base) filename.

Hmm, regarding embedded thumbs, don't P-TV videos follow the old naming conventions? I downloaded one from my brother's PSP (JP)

http://jonny.leffe.dnsalias.com/pmp_mod_avc/index.htm

General HowTo:
rip DVD with DVDDecrypter (or other ripper)
Use GordianKnot to make d2v and avs files (hint, use TomsMoComp for deinterlacing). use the following for output resolutions:
4:3 = 368x272
16:9 = 480x272
2.35:1 = 480x208
Use BeLight to transcode ac3 audio to mp3.
Use x264 to transcode avs to h.264. Here's the commands I use for two pass:

x264.exe --pass 1 --bitrate 750 -A all --level 3 --pictiming --aud --no-psnr --thread-input --progress --output NUL ep6.avs

x264.exe --pass 2 --bitrate 750 -A all --level 3 --pictiming --aud --no-psnr --thread-input --progress --output ep6.264 ep6.avs

Finally, use pmpmodavc_muxer to make the pmp file. This makes excellent looking and sounding videos.

My AMD X2 4600+ gets about 62 FPS while encoding using the above settings (61 FPS on pass 1, and 63 FPS on pass 2). :)

What's the disadvantage of using PMP Mod? I heard something about restarting the PSP? I'm not sure how that works and if you can explain that to me that would be great.

Also, are your settings high quality settings? Why are you not using AAC? If I want to add subtitles, does it "burn" the subtitles on to the video frame or it's like a DVD in which the subtitles itself is on a separate file and not "burned" on to the movie?

Is there a demuxer for the PMP format? For example in the future, I might want to switch to another format. Thanks!

The main PMPMod site is here (http://jonny.leffe.dnsalias.com/). The thread link under PMPMod leads to a ps2dev forum thread where PMPMod and PMPModAVC are discussed. They are just about to release a new version of all the different PMP software from the look of things. From posts at ps2dev, it looks like the new version will support aac.

You can get a version of PMPMod(AVC) that supports subtitles here (http://www.fx-world.org/wordpress/?cat=2). MicroDVD and SubRip format are supported. These are softsubs, not hardsubs.

PMPMod(AVC) works like other homebrew - you run it from the games menu in the xmb. When it runs, it gives you a list of all the .pmp files found in ms0:\PSP\VIDEO\. Press X or O to play the selected file, and triangle to exit back to the xmb.

I use BeLight to encode the audio as 192kbps ABR MP3 at 44.1kHz (high quality for a PSP). Like I said, the new version they're testing now looks to play aac. The x264 settings are high quality... probably overkill on the bitrate, but that bitrate guarantees me high quality episodes with the whole series fitting on one DVD-R. 750kbps video and 192kbps audio yields a 24m38s episode of 168MB. They look and sound awesome.

Thanks for the information, but I have some more questions right now.

Does the PSP support VBR though? I rather do a 2-pass VBR and let the encoding programs determine the approriate bitrate for both the video and audio. I don't have a problem using MP3 for the audio since it's a 2-channel solution anyways.

So the muxing will not "damage" the video and audio files at all? If I demux it in the future, the video and audio will still be the same?

Which subtitle format do you recommend? Which one is the most commonly used? What do you by soft sub and hard sub?

I thought someone said that using the PMP mod will require the PSP to restart or something like that?

ilovejedd

7th March 2007, 06:40

If you do a 2-pass, video is VBR. What you have specified is average bitrate so complex parts are allotted more bitrate and simple ones less. You don't need PMPMod for that as it's supported by original firmware.

Do you mean you want to do a quality-based encode? You can do that, too, especially now that the resolution and bitrate limits have been lifted from custom firmware.

Muxing does not damage audio and video. Yes, the demuxed video and audio will still be the same.

I'm not sure what subtitle formats PMPMod uses. Most likely .srt or .ssa. I've never used the SUB version as when I first tried the original iteration, the native video player was much better interface-wise. Since I'm re-encoding videos either way, and I won't be viewing the encodes on anything other than my PSP, it was easier to just convert videos to the format PSP natively supports, even with hard subs.

hard subs = subtitles are written directly on to the video and cannot be removed without damage to video
soft subs = subtitles are not part of video stream and can be turned on or off at will

Hmm, think:
hard subs = text written with MS Paint (replaces pixels in orig pic)
soft subs = text added with PhotoShop (separate layer independent of orig pic)

PMP is homebrew and runs like any regular homebrew application. There's no reason why you'd need to turn off your PSP to run it if you don't need to do the same for, say, File Assistant.

Two pass video is VBR. I also encode the audio as ABR, which is VBR that tries to make the overall average about the same as the rate you select. PMPModAVC handles VBR video and audio just fine.

So the muxing will not "damage" the video and audio files at all? If I demux it in the future, the video and audio will still be the same?

Yes. Muxing is simply a way of mixing all the data streams together into a single file. None of the streams are altered.

Which subtitle format do you recommend? Which one is the most commonly used? What do you by soft sub and hard sub?

When I do subtitles, I do soft-subs in SRT format. SRT is probably most common.

Soft-subs - a separate text file with the subtitles, and timing info. Requires an OCR program that converts the VOB subtitles into text (like SubRipper). Pros: small text file makes it easy to store and edit. Player program can use high-quality fonts to display the subtitles, making them easy to read. Cons: player program must support soft-subs, and it takes time to draw subtitles over the video frames.

Hard-subs - the subtitles are rendered into the frame before it's encoded. Pros: works with any player, no slow down to display subtitles. No OCRing needed. Cons: makes frames harder to encode, thus decreasing quality just slightly. Stuck with font used when encoding the frame (and some subbing groups use LOUSY fonts at stupid sizes).

I thought someone said that using the PMP mod will require the PSP to restart or something like that?

Not anymore than any other game causes the PSP to "restart". After watching the vid, you exit PMPModAVC and you're back at the XMB like after exiting any other game or program.

No, that's constant quality, another form of VBR. Multi-pass VBR tends to be called ABR (Average Bit Rate) because it tries to make the work as a whole have an average bitrate close to what the user specified. In the case of the example command lines I gave, I specified an average bitrate for the whole clip of 750 kbps.

CBR - Constant bitrate. The media encodes at a constant bitrate, giving a fixed size, but a constantly changing quality. For constant bitrate with x264, use the "--bitrate" option (for example, --bitrate 512 ) without using the "--pass" option.

VBR - Variable bitrate. Has two main variants:
CQ - Constant quality. The media encodes at a set quality level, giving a completely variable bitrate and size. For constant quality with x264, specify the "--crf" option (for example, --crf 25). The higher the number, the higher the quality. Another way is to specify a constant quantizer using the "--qp" option (for example, --qp 18).

ABR - Average bitrate. Bits are shuffled from parts of the clip that don't need them to other parts that do. This gives a fairly fixed size and a fairly constant quality, but the bitrate changes constantly. ABR can be done with a single pass, but isn't nearly as good as multiple passes. For average bitrate with x264, use the "--bitrate" option along with the "--pass" option as shown in my examples several posts up.

Multi-pass VBR tends to be called ABR (Average Bit Rate) because it tries to make the work as a whole have an average bitrate close to what the user specified. In the case of the example command lines I gave, I specified an average bitrate for the whole clip of 750 kbps.

CBR - Constant bitrate. The media encodes at a constant bitrate, giving a fixed size, but a constantly changing quality. For constant bitrate with x264, use the "--bitrate" option (for example, --bitrate 512 ) without using the "--pass" option.

VBR - Variable bitrate. Has two main variants:
CQ - Constant quality. The media encodes at a set quality level, giving a completely variable bitrate and size. For constant quality with x264, specify the "--crf" option (for example, --crf 25). The higher the number, the higher the quality. Another way is to specify a constant quantizer using the "--qp" option (for example, --qp 18).

ABR - Average bitrate. Bits are shuffled from parts of the clip that don't need them to other parts that do. This gives a fairly fixed size and a fairly constant quality, but the bitrate changes constantly. ABR can be done with a single pass, but isn't nearly as good as multiple passes. For average bitrate with x264, use the "--bitrate" option along with the "--pass" option as shown in my examples several posts up.

Does Autonot Gordian have an option to determine the best VBR or ABR bitrate for the encode?

Also, how can I determine which bitrate to use for VBR to ensure that it has a reasonably quality to size ratio? How did you come to the conclusion that 750kb/s is too much for PSP resolution?

Autonot Gordian - haven't heard of. AutoGordianKnot, I believe, has options for Constant Quality or ABR (given target size) encodes.

How do you define "reasonable quality to size ratio"? For my encodes, I use x264 2-pass 300kbps for video (anime eps, 320x240). One episode usually falls around 60MB so I can cram two 26-episode anime series on my 4GB stick with room for some music. Videos are not perfect but they're good enough for me. In my case, I opted for size rather than quality and I consider the trade-off reasonable. For live action, I usually use 400-500kbps. For the rare titles that I want in near perfect video (in my eyes), I use a bitrate of 768kbps.

Regarding 750kbps being overkill given the PSP's screen resolution, it really depends on you (and your eyes) whether the quality is acceptable or not. I suggest converting a couple of short clips to PSP format using various bitrates and/or quantizers and watch them on your PSP.

Isn't there a bitrate calculator for h.264 content? I remember there was a bitrate calculator for xvid.

Basically I just want to let the programs determine the ideal bitrate to use to encode. Is that possible or I need to determine that myself?

ilovejedd

14th March 2007, 16:25

Bitrate calculator for either is the same as what bitrate calculators do is just ask you how long your video is and how big you want your file to be. You can do the calculations manually:
video bitrate = target filesize/total time - audio bitrate
*target file size in kilobits, e.g. 4gb is 4*1024*1024*8
**total time in seconds
but thankfully, bitrate calculators are there to make your life easier.

Ideal bitrate for what? Quality? Encoders won't know if the quality of a certain video is good enough for you. File size of encode? That they do, and that's what they're made for. So if you want to cram all three Lord of the Rings movies onto say a 2GB memory stick, a bitrate calculator will tell you what bitrate you should use. However, it is questionable whether the encodes will look good (although I reckon they'd probably be passable, maybe VCD quality or so).

(Auto)Gordian Knot has settings for bitrate and quality, but I never worry about them as I just use GK to generate the avs file. I do the encoding via command line (as shown earlier) which specifies the bitrate.

The best way to know what bitrates to use is experience. Encode different material at different rates and see how they turn out. Do 5 to 10 minute clips so that it doesn't take too long. You can tell when you're getting close to the proper bitrate - you start getting block noise in the dark parts of scenes. Dark scenes normally have the most bits stolen in multi-pass encoding since the eye isn't as discriminating at low light levels. When too many bits are stolen, you start to see blocks in the darkest part.

For example, most of the episodes of Cowboy Bebop I encoded at 750 kbps show little to no noise. However, a couple episodes are harder to encode and require a higher bitrate. A perfect example is the episode "Brain Scratch" - if you're familiar with the series, you'd remember that this episode has a LOT of scenes that feature effects that simulate a TV image... white noise, scan lines, retrace lines, focus issues, etc.. Even at 750 kbps, this episode has some noticable block noise in the dark scenes, indicating that it could actually require a slightly higher bitrate.

So in the end, just play with it. See what looks good to you. You're the one that will be watching it after all.

Has anyone here installed the latest firmware 3.30 on their PSP? It supposedly added support for MPEG-4 AVC Main Profile 720x480, 352x480 and 480x272. Anyone tested some videos yet?

I'm still on 3.03 OE-A. Xenogears works with it quite well and there's been no compelling reason to upgrade so far so I haven't changed the firmware yet...

nope didnt know there was one, but ill have a look right now, once i have updates :)

edit: would make sense though, with the ps3 functions, now you can encode for one and play on both...

update: 480x272 works, although it doesnt fill the screen unless you manually select it. odd... and the firmware said about thumbnails now working in the video folder, i havent tried it though

update2: 720x480 shows up, but says video cant be played. this could just be me rush testing though...

deets

Hehe it was only a matter of time after Apple opened 640x480 on the Ipods but Sony could have allready allowed it after UMD's dead so even before Apple released the higher res because of TV Series and Apple TV, but better late then never.
But this Firmware Restriction stuff still has a big influence on me in terms of missusage for higher profit makeing, im very skeptic about this new way it's being handled @ the CE companies and content providers (they want so deep into your pocket for every itzy tiny thing that was just normal before and now is being controled in every way and the customer is blocked from it's usage i find this to be a very big moral problem if you know what i mean so im happy we have all the new generation of firmware hackers being born and not only the .NET generation that doesn't know anymore what MOV or EAX means ;) ).

Scarpad

So what happens to 4:3 vids, If I encode at 480 the other res would not be 272 so does that mean it will not play? And are we sure 640x480 won't work?

Atak_Snajpera

30th March 2007, 18:38

If you want 4:3 you have few options:
1) resize to 368x272 , add borders (56,0,56,0),add --sar 1:1 to cli. You will get 480x272 but with black borders
2) resize to 480x272 and then add --sar 4:3 to command line
3) resize to old 320x240

Personally I use first method because it gives better quality compared to rest.

there's a serious bug with this version.

when you playback 480x272 video, the button two pixels are cut. simply add two pixel white border to button and you can check this issue on PSP.

hope SCE would fix it in next update.

Actually, I don't think it's a bug. PSP video downloads from the Japanese P-TV site have a resolution of 480x270. That's exactly 16:9 aspect ratio. And its been like that since... hmm... forgot when I downloaded exactly but I think November '06 at the latest.

I get 16:9 with 368x208 but that involves scaling the image. I am guessing with 480x272 the image does not need scaling which equates to improved resolution? Given that Memory sticks are so cheap these days, might be worth doing

Might give it a shot then. I don't run homebrew so 3.3 should be a straightforward update. And all it seems I have to do to create the higher resolution video is a scale option in the Avisynth script and increase the bitrate in x264 (I don't use MeGui).

the video decoder on PSP do low quality upsamling in UV planar, so when you play 480x272 on PSP, you would notice some jaggies on the edge of blue and red color.
720x480 have higher resolution in UV planar so the edge would be much more smooth.

here's a compareshot made by cyrax.(I don't use CFW so I can't do screen capture on PSP:p or I would provide a much obvious compareshot.)

of course 720 also gives you greater scope for playing back through other devices such as your TV via PS3. I hope the encodes would work on the ps3, no reason to think they wouldn't.

18th April 2007, 17:47

Isn't being able to use just one file/encode for PSP and PS3 playback the whole point of adding support for 720x480 resolution? Albeit, you'll need much higher bitrate ergo, high capacity memory sticks for this. Since I backup my DVDs to MP4 for PC viewing, saving time and effort on encoding videos specifically for the PSP is definitely a good thing. I've got a couple of 4GB sticks anyways, and some spare 2GB and 1GB ones, too. :D

@ ilovejedd
exactly that's what SCEI archived here as the first company on a Mobile Device with AVC :) and now it's available for the Public (after the Death of UMD), but i think it would be availabe anyways from the Custom Firmware Hackers
Sony knew that so they opened it before the Scene did and now try to force people back into their protected firmware enviroment, but it's to late ;).
Most probably it was Sonys initial plan to make UMD playable directly on the PS3 or via remote to have even their own SD format established so Blue-Ray for HD content and UMD for SD (Home,Mobile) it had the potential to become that but Sony made alot of mistakes in the process but that is goodfor us now the Public has the mastering capabilities that before the day of the 3.30 firmware only SCEI Licensed Companies had with the UMD Stream Composer (Confidential .NET Based Encoding Application useing Sony's AVC Base/Main Profile Encoder and Motion Adaptive Deinterlaceing Technology).

in a previous post I stated that 480x272 would be cropped 2 at bottom, and might have a quality loss in 480x270->480x272.
the truth is
cropping is applied, but PSP actually display 480x270 centered on the screen, so this isn't a problem at all:p
thus when you encode 480x272, you should put AddBorders(0,0,0,2) after resize to 480x270.

another auto cropping is applied when play 720x480 too: 8 pixels each at left and right.
just like what you did to maintain right AR when ripping NTSC DVD.
thus when encode directly from NTSC DVD, no cropping is needed.
when encode from "AR corrected" clips or HD source, first resize to 704x480, than AddBorders(8,0,8,0)

Yup both 480x272 and 720x480 work fine for us too.
We have released a beta version of PSP Video 9 that supports these resolutions: http://www.pspvideo9.com

From our testing, it looks like the PSP will only playback video at those specific resolutions (480x272, 352x480, 720x480) and nothing in between (like 640x480 or 512x384).
Can anyone else confirm?

Just tried out this version. It doesn't seem to support avisynth scripts which is a showstopper for me. When profile (with avisynth) is selected, it ignores the content of the genericfile.avs file in the avs directory.

I use PSPVideo9 with avs all the time. Try playing the avs in MPC first - I've found that if you make an error in the avs, PSPVideo9 bombs out rather than tell you an error occured. I've gotten in the habit of playing the avs in MPC before going into PV9 just to be sure.

Getting in MeGui which looks like a good one step method of encoding lots of videos for the PSP. But am having a problem with audio I can't resolve.

Most of the videos I encode have AVI files with VBR MP3 audio. Up till now I have extracted the audio as a wav file which I input to neroaanenc to encode to MP4. Then of course x264 to encode the video and MP4Box to mux the two files.

This works fine in MeGui so long as I extract the audio first (I use Avidemux2) and input that to MeGui. But that defeats the one step process. So taking a tip from Deets I pass the avisynth script to the audio encoding part of MeGui. MeGui opens the file okay, seems to process the audio but ends up only creating a 1M file. Playing that file with QT indicates that the length is right (about 42" for a TV show) but of course with a 1M size, there is no audio.

For the audio encoding I am using NDAAC and choosing the PSP-LC-96 profile

Just wondering what I could be doing wrong here. Any pointers would be helpful

Thanks

In the avisynth script's source, there wouldn't happen to be an audio=false, would there? Avisource and Directshowsource will normally load audio if it isn't disabled.

(42" is 42 seconds, 42' is 42 minutes. :p)

lchiu7

25th April 2007, 07:57

No I actually have audio=true in the directshowsource command

Update:

I have tried a number of different ways:

1. feeding into MeGui compressed wav files (select Nero Digital as the MP4 encoder)
2. Feeding the Avisynth script into MeGui

More often than not, I only get a MP4 file which is about 1.5Mb in size

I also tried feeding in a compressed wav file and didn't turn on the Always use DirectShow option and MeGui dies with an error in AviSynth

I am sure most users of MeGui are doing this in one step with no external programs to extract audio - just wondering how they did it?

Here's a common AVS script I use with PSPVideo9... just load the avs instead of an AVI.

loadplugin("C:\DGMPGDec\DGDecode.dll")
loadplugin("C:\Program Files\AviSynth 2.5\plugins\Decomb.dll")
mpeg2source("C:\temp\rips\DVDNAME\name.d2v",cpu=6)
fielddeinterlace()
audio = WAVSource("C:\temp\rips\DVDNAME\track.wav")
AudioDub(last,audio)

The last version of PSPVideo9 I used didn't take ac3 audio, so I ripped the audio to wav and reinserted it into the avs as shown in the script.

There's actually an AC3 filter for AviSynth. You can download it from the AviSynth Filter Collection page (http://avisynth.org/warpenterprises/), just search for NicAudio. It also contains a filter for DTS.

Thanks! That should simplfy things quite a bit on the audio side. :)

@billou2k: Sony is rather notorious for being slow on PAL support. It took a number of updates to pops before they finally supported PAL PS1 games decently. I imagine in another few updates, they'll have 720x576.

Why do you use 480x256? (aspect ratio - 1.875?). Movie encoded in this resolution will be stretched vertically on PSP. I use following values to maintain correct aspect ratio.

16:9 - LanczosResize(480,270).AddBorders(0,0,0,2)
4:3 - LanczosResize(360,270).AddBorders(60,0,60,2)
2,35:1 - LanczosResize(480,204).AddBorders(0,34,0,34)

2,35:1 - LanczosResize(480,204).AddBorders(0,34,0,34)

Trying to keep the same aspect ratio as the source if possible. And trying to avoid "AddBorders", using the oneclick function in megui

handtruck: Did you check your movie on PSP. Stretched or not stretched? Some time ago I checked 480x208 and it was stretched. You have two choices:Addborders or wait till Sony fixes this issue.

Which resize filter do you guys use when encoding mp4(720*480) for psp? It looks a little too sharp with lanczosresize.

I'm assuming your original source aren't NTSC DVDs, maybe HDTV caps or PAL? Anyway, I use BilinearResize. It's really fast.

I use BD or HD-DVD as source. Bilinear? I'll try this one! Thank you!

Sorry if this has been answered before, I couldn't find the answer in the forum search.

How do you add the SAR setting in MEGUI? I don't see a DAR or SAR setting in the config screen for MEGUI, only in x264 vfw config, but that is already set to 1:1. My command line in MEGUI does not have the sar setting, and cannot be edited, so I am restricted to what the options in the config screen are. As a result, the output ar on the PSP is incorrect (L/R borders). I'm, using MEGUI 0.2.4.1039.

Thanks!

go to the second tab in x264 config and go to custom command line to add --sar 1:1

I actually came across the guides on that site (http://www.bontragerphotography.com/psp/) and it inspired me to get a PSP, now that full res is supported!!!

Sony owes that site some marketing fees ;-)

Just as a notice for the archives, in case someone stumbles upon the same problem as I did (I didn't find any mentions of this anywhere):

The PSP (tested on 3.40 OE-A) doesn't like it if the timescale of the video track multiplied by its length in seconds exceeds 2^32 and just shows "Unsupported data". Usually this should not be a problem (unless you're going for incredibly long movies) but in my case the input file had 23,976023fps which x264 dutifully converted to a time scale of 23976023 which resulted in an overflow after just below 3 minutes.

Has the problem with encoding with a dual core processor (--threads 2) been fixed with any recent PSP firmware release. Having just gotten a dual core Intel, I am keen to use both cores but the only test I did made a file that would not play on 3.3 firmware while it played okay in QT

Thanks

if your using megui for your x264, use threads=0 and that will set things to auto threads, which works well here.

it hasnt been fixed as slices wont work, but the different way x264 now use threads will work on the PSP just fine

It means use AssumeFPS(24000/1001), or NiceFPS or (only if you have 2.57+) AssumeFPS(23.976) at some point in your avisynth script, or it might break playback.

Have a new box with a clean installationof Visa Home Premium on it. Built a faster machine so I could encode more quickly. After some travails got x264 to work okay (got my single pass encodes of xvid into h.264 up 60fps on a AMD X2 3600).

But can't get mp4box to run. Whenever I try to combine the .264 file and the .mp4 file (created by the Vista compatible version of neroencaac) get the error

cannot open destination file xxx.mp4: I/O error

Yet strangely if I move the .264 and .mp4 files created on Vista to a XP box, mp4box works fine.

And files which combine okay on my XP box generate the same error as above.

Anybody out there using Vista as a platform for encoding video for the PSP and have struck this problem?

Thanks

[Update]

This is getting really weird. I ran mp4box on a XP box but on the Vista drive mapped over the network. Get the I/O error again so it's not a Vista problem.

Then ran mp4box on the Vista box but using the files on a mapped drive on my XP box and it worked also.

So it's some strange problem with the drive on the Vista box. But this is a brand new installation of Vista on a brand new Hitachi 250G SATA drive so can't think what the problem could be. The MP4 files play fine on the Vista box with QT so it can't be bad sectors or hardware issues like that

Hmm could be Mp4box not so optimal temp system on win32 try the same with mp4creator same problem ?

26th May 2007, 22:42

I have no idea what's going on. Connected a USB drive to my Vista box and can run mp4box on that. Just can't run it on my main boot drive. This is the strangest thing

Larry

[Update]

Move the USB drive to the Vista box as an internal drive and mp4box works fine on that drive. Just doesn't work on the boot drive. This is really strange.

28th May 2007, 02:31

mp4box uses root directory of a drive which working files exist as temporary directory by default on Windows System.
So if no permisson to write on root directory, mp4box can't make mp4 file.

The solutions in 3 ways.
1. Work at a drive which you have permission to write on root directory.
2. Run mp4box as administrator.
3. Run mp4box with an argument `-tmp some_directory_which_you_have_permission_to_write_on'.

28th May 2007, 11:08

Thanks. For another reason I turned off UAC in Vista since I was getting annoyed with access control coming on all the time. This also fixed the problem. Certainly a trap for unwary players

For simplicity's sake, would Nero make for some easy MP4 AVC recording at 480x272 for the PSP? Would it be easy to put subtitles in with Nero?

3rd January 2009, 11:10

so .. is 720x576@25fps working? the only thing *i* care to encode in a while, and it's a PAL TV series. trying to maximize compatibility (not sure what my 5 b-frames will do, tho .. as well as PAL resolutions).

Deinorius

5th January 2009, 12:28

Why not resize to 480x272? You will get no quality boost by using full resolution. 25 fps should be running, but I'm not sure, if I tried with such a file already.

Ah, I got it. But IIRC PSP is just supporting up to 720x480. Of course the best way to test, is to try it yourself.

teddg

6th January 2009, 19:01

i'm trying to do a "one encode for all" .. targeting highest quality playback (so no resizing outside of the player doing it via --sar x:y), but also being PSP compatible. in this case the video is widescreen so i dont' have to worry about forcing fullscreen (on the PSP).

Ah, I got it. But IIRC PSP is just supporting up to 720x480. Of course the best way to test, is to try it yourself.

psp now supports 640x480 in addition to 720x480 since the last update.

Don't crop letterboxing, if you do you'll loose one of the zoom/fullscreen options on the psp (I forget in which particular case).

I also do a "one encode for all". Unfortunately, psp can't do 8x8dct (and i8x8) or more than 3 refs. It can handle huge bitrates though.

And MY PSP with latest firmware 5.02 says that such video is not supported....
Anyone knows why???

lexor

7th January 2009, 22:53

Anyone knows why???

Yes, it's because of:
put the [mp4] header at the end instead of the start. That's the method x264 uses for outputting an mp4 to stdout.

you have to remux or use qt-faststart for many devices and for web playback when using either x264's or ffmpeg's muxer. This is by design.

Basically, demux the mp4 file to raw streams and mux again with megui to mp4.

For the future, it's easier to just encode to raw, and then mux (this way you don't have to demux after encode)

fachman

7th January 2009, 23:49

Thank you very much Luxor.
I wonder why x264 is using by default the settings which breaks compatibility???

Anyway I have tried to demux the file with mp4box and it quits with an error or says that is can not find js32.dll
I have VISTA64....

After a while I have found it would work with older MP4box build from October...

Your solution worked flawlessly :thanks:

Sharktooth

8th January 2009, 04:20

coz x264 cant fill the header with data it doesnt yet know.
it has to finish the encoding and then write the header at the end.

fachman

8th January 2009, 23:44

Sharktooth:

Thank you very much for the response and great programm MEGUI :)
Would it be possible to make the logs not to disappear when for some reason MEGUI quits by accident. (I have many problemms with stability of AVS script with FFT3dGPU filter and lost a lot of precious statistics)

As for the header when I have compared two files the only difference at the begining was AVC1 which was not produced directly by x264.
Of course I assume there are also more informations, but I think MP4BOX should write the correct header when muxing such mp4 file with sound. Is it possible???

Best Regards

Sharktooth

9th January 2009, 14:34

look inside the logs directory. if the log is incomplete then megui crashed for some reason.

yes, mp4box writes the header on the beginning. so whenever you remux the mp4s produced by x264 with mp4box, the header is placed where it is supposed to be.

fachman

9th January 2009, 20:37

Hello

THe logs are written when you leave the MEGUI normally, if the programm is terminated by windows all statistics is lost. I think Megui should save the statistics as soon as it will end the single coding, so when the FFT3DGPU hangs the system with the next file, the statistics wont be lost.

MP4box writes the header correctly only if you use raw stream. If you use MP4 produced by x264 it does not.

Greetings

The easiest way to encode for psp if you own a Linux pc or Mac OS pc is encode-handheld.pl. The latest revision is 3.1. It will build you flawless 480 width files that will play on any iPod, Zune, or PSP. It is very simple to use. Google it, currently only available via torrent.

*firmware 5.01 (Sept, I think). This update added 640x480 support, in addition to the 720x480.
