x264 and Sony PSP?

[nrx][Natas]

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

[Scarpad]

@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.

[Scarpad]

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)

Actually Demand helps to drop prices. Memory stick prices are falling since the PSP came out. Also UMD prices are falling and it's commonplace for a new title to be on sale with it's DVD Counterpart, the Longest Yard was an example on sale last week for $14.95. Also a Used market is croping up. I picked up SWAT this week for $7.50 used.

[Scarpad]

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.

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.

[nrx][Natas]

[Natas']Okay...than there is something wrong...

I'm encoding Scrubs S01E01 PAL right now .It starts with 30 fps and now after 30% it's encoding with 14.7 fps and it's getting slower and slower... :confused:

[AnimeTheme]

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

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.

[azsd]

install Elecard Mobile Converter 1.0 then connect like this:

I use your suggested setup... but it doesn't solve the frame skip problem. I use a x264-encoded file (muxed with MP4BOX) as source, and then remuxed with Elecard muxer. The resulting file plays on PSP at like HALF frame rate (choppy), and the frame skip problem is still there at all I-frame.

Did you try remuxing movies for PSP using Elecard muxer? What was your result?

[nrx][Natas]

Hi,

i still have the framerate problem. So I tryed the same thing with DivX6. With DivX6 I have no problem with encoding speed of the second pass. 20 - 30 fps. But x264 is getting slower and slower during the second pass. Any idea?

thx

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. :)

[DeathTheSheep]

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.

[AnimeTheme]

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!

[nrx][Natas]

I updated to 2.50 a few minutes ago and i hope it now supports 25fps, too. But i don't think so :D .

Anyway, right now i'm encoding without ChangeFPS and encoding speed for the second pass is 30 fps. ;)

You can read about my problem with ChangeFSP a few posts above.

@AnimeTheme:
Do you use ChangeFSP? What programs/settings do you use? I use MeGUI.

thx

[jonny]

are the resolution restrictions gone on 2.5?
and interested on fps too :)

[Natas']@AnimeTheme:

I use x264 + MeGUI. If I have to change the frame rate of the source, I use ChangeFPS as well.

[DryFire]

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.

[nrx][Natas]

Hmm okay. Than one of my settings causes my speed problem.

When I use this

start /belownormal /b /w x264.exe --progress --bitrate <bitrate> --analyse p8x8,b8x8,i4x4 --output video.264 psp.avs

it works greate with ChangeFPS, normal speed!! :D

Now i add some parameters to check what works an what does not :)

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)

[DoC hEx]

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.

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.

[nrx][Natas]

Hi,

here are my latest cli settings that works :D

start /belownormal /b /w x264.exe --bitrate 200 --keyint 300 --bframes 2 --subme 6 --analyse p8x8,b8x8,i4x4,p4x4 --qpstep 1 --me umh --zones 196815,206208,q=40 --progress --no-psnr --output BeCool29.264 BeCool29.avs

Now I'll try it with MeGUI and 2 pass encoding. :)


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?

[Synergy37]

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.

It would be nice if they somehow hacked 2.5 so that it wouldn't require 48khz audio and 29.97 fps. Maybe even some vorbis support....

Ok, here we go again. Nothing changed with rev 333c. I disabled all background programms, nothing.

Could AviSynth be the problem? Because without ChangeFPS it works. What version do you use? I use 2.5.5. I think i should reinstall all encoding tools :D .

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?

[jonny]

i'm testing video only atm, 480x272 mpeg4 sp @ ~800-900 kpbs, with the current player should give 17-19 fps.
with optimization i think can be pushed up to 30-35 fps
All of this with the cpu @ 333 mhz

testing on battery life should go *after* all the optimizations are here (there is no point talking on this without having real numbers/real tests).

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!

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.
