PlayStation Portable (PSP)

[bibbo]

Since sony claims that PSP has h.264 support, i was trying to make some videos with Nero Recode (Portable AVC), but the PSP refuses to play them. I tryied all kind of configs, and also changing the mp4 container (mp4UI).
I can play fine some videos fron IGN. How can i get the specs of the PSP video player?

I Don't have a PSP yet however this link may help. Apparently Nero Digital should also work however I have read how some people get it to work and others don't.

Also something else I read was that you have to put it into a particular folder on the memory card.

i doubt that the psp supports h.264 (aka mpeg-4 avc) already, afaik it currently supports mpeg-4 asp

nerodigial .mp4 files are normal .mp4 files! you can encode in nero recode2 in both avc and asp
also you can try creating files with 3ivx too, or simply muxing divx5/xvid streams in .mp4

Although I can not verify anything as I don't have a PSP, Everywhere I have read say that the PSP uses the newer MPEG-AVC and not MPEG-ASP.

Here is just one of them

However it is quite awkward to get the PSP to play videos, for instance the files have to be named in a particular way and placed on the memory card in certain folder. I have also seen quite a few people mention using a perticular 3GP Converter to get it to work.

well according to this site PukiWiki(is a japanese site) the PSP only supports
"MPEG-4 Visual Simple Profile" (i think the mean ASP)
and AVC hasn't been verified at the moment (at least playing from Memory Stick DUO)

btw i haven't got a PSP, so asking me is pointless
but the data from the site seems to be accurate

[Abnormal1]

Its all very confusing and until someone on this forum actually has one to play with I will not believe what I read on other websites.

take a look at the following link (encoder + discussion)

mpeg-4 simple profile is indeed different than advanced simple profile (asp), have a look at my mpeg-4 info sticky for more infos about that

Ah so at the moment the PSP supports only simple profile (no b-frames,
no GMC and no Quarter-pel Motion Compensation)
btw seems to have overread you first post :shame:

i doubt that. even from memory stick you can play videos with more than 15fps (although nobody managed to play full res videos (480x272) yet). i'd say that's a clear sign it does support advanced profile from umd _and_ memory stick.

simple profile doesn't means limited to 15fps
http://www.m4if.org/resources/profiles/visualtools.php

well the 3gp convertor uses

ffmpeg <input file>-bitexact -vcodec xvid -s 320x240

so simple xvid without bonus stuff

maybe the h.264 decoder is somehow connected with the UMD drive
and only useable with UMD movies.

btw it was said that the firmware of the PSP is upgradeable
so maybe the some features are still not unlock for now

too bad that we haven't have someone from sony in this community...

strictly speaking all the levels (eg subparts of profiles) define only up to 15fps
still this doesnt mean of course that the player doesnt support higher framerates too (its just not sure)

[weak]

ok, so the fps mean nothing.

unfortunately i have no memory stick and shops are closed (public holiday). but i'll buy one tomorrow and try some other resolutions and stuff.

it would sux if only umd movies can use the full resolution.
but since game developers are planning to release additional content and demos through the net i still hope it's possible.

I couldn't get Nero's AVC to work on PSP, yet.

There are some restrictions that I have come across when testing:

No bitrate limit for audio nor video.
Audio can't be more than 24000Hz
Video must be 320x240

If someone is using the "3GP_Converter" here is my take on 2-pass xvid encoding profile that will work in PSP:

i thought 25fps will work too?

the resolution thing sucks most. maybe you have to encode using h264 to get the full res? h264 is definitely possible if you can trust the system specs.

anyway, i've bought a memory stick meanwhile but i still need the usb cable (gonna pick up one from a friend today).

----------edit:

videos @ 25fps do play, but the audio is (completely) out of sync. (source material was dvb-c recorded mpeg2, PAL).

[ECY]

So does it support h.264/avc via Memory stick ?
(maybe try without b-frames)

hope to hear more results soon ^^

[works]

I tried to play Nero's AVC files made with Mobile and Portable profiles, but no luck. I'd _love_ to get it to work, since the PQ is much better.

edit: I'm also having some severe audio synch issues with PAL material (yea, got 25fps working, dunno what was the matter before)

Also updated the 2pass profile couple posts up.

I've got a PSP now and it's a beautiful little device, even if the MP4 playback is far from ideal. You can still get some nice results but cramming a 2.5 hour action movie onto the memory stick is very difficult.

I can't get Star Wars Episode II with reasonable quality to fit onto a 512MB memory stick, for example.

Firmware updates may cure some of these limitations but I doubt it - unbelievably Sony thinks that people will pay money to watch movies at less than DVD quality on a very small LCD screen.

The way forward is through the fact that the PSP can run executable files from its memory stick (witness the GAME function under the memory stick menu). So it's not beyond the realms of possibility that somebody will produce a better media player than the one that is built-in to the PSP... once the homebrew coders have got their heads around the system, any way.

[easy2Bcheesy]

Has any one got any Nero Digital profile to work? 3GP/ffmpeg seems to have a number of issues with its quality-based profiles - great on motion, terrible at relatively static screens.

from the psp manual from the FCC site:

Compatible Codecs: Video - H.264/MPEG-4 AVC Main Profile Level 3 Memory Stick (TM); MPEG-4 SP, ACC

link to page4 (containing the above mentioned info)

so it's clearly capable of H.264
