PSP format video

[bond1972]

Hi,

I have been trying to create video for the PSP. I understand that it must be H.264 MPEG 4. Can anyone please confirm what settings I should be using and which Codec I should use.

I have also read that ffmpeg can be used, I cannot see how to select this codec for the output.

I look forward to your response.

Regards,

Ok...

All you need to do is go to Sony’s website and download there free PSP MPEG4 Audio Video encoder. The software is free in every what and it works well with DVD Decoder. I have seen it take the ripped VOB's and encode them into fully playable video files on my friends PSP. He has a 1 GB Memory stick and has on it at this time 3 GundamSEED Destiny episodes and some songs. It’s not that hard man. It even crops video for you if you wish to make 4.3 video into the PSP’s native 16.9 or just leave it 4.3.

I have used this software (and a number of others). When VLC converts to MPEG4 it is at around 5 x the speed of the Sony software. I would also like to be able to write my own program to manage the video files and hence would like to be able to run the program from the command line (at the very least).

Oh I see. Ok sorry if I came on strong but I was unaware of your having used the Sony encoder already. I use VLC to encode MOV's for my website all the time so I know it works but you just need to nail down the encapsulation and codex. You have the codex but do you have an appropriate encapsulation format?

[bond1972]

No problem.

How does VLC handle encapsulation (I think I understand about Codec). I'm sorry but I am not anything approaching an expert in this field. Does anyone know how to use VLC to create PSP MPEG 4 files, I would have thought that I am not the first to be trying this.

Encapsolation simply put is the method the file is transfer in a stream. Mpeg TS is different from MP4 or OGG. I just find that using an MP4 video and audio codec I can use ether the MP4 encapsulation for MP4 files or MOV encapsulation for MOV files as that is the real difference between the two formats. I am not aware of the needed encapsulation but VLC is able to encode the H.264. Try using the H.264 video codec with an MP4a audio and the MP4 codex for your encoding and stream the video to a file with a .mp4 extension. That might just do it, or it might just make a file only VLC can play. I can’t test it for you as I myself do not yet have a PSP game system for my self. I only have made MP4 and MOV files so far and I don’t use VLC as my mane encoder any way as it has no frame rate control.

. The H264 codec's PSP uses are little modified to origin one. It uses some non-standard flags (caled atoms here). It makes movies converted by QT to MP4 umplayable on PSP which means, the one made by VLC too.

Why can VLC play the PSP mp4 format just fine? I mean.. im using a stand alone tool to code psp movies from eg. dvd or similar.. thats fine, but then VLC show the stream just fine.. no errors or anything, so why is it impossible to transcode to this "strange" format with VLC?

My current "project" is to get to stream live video from a Dreambox -> PC with VLC -> Transcode to PSP MP4 format directly.. But no matter what i set of resolution or whatnot, the PSP always show this as "Unsupported format".

Is there a addon or a codec i can insall in VLC that can fix this? The point of this is to use VLC in one go, as streaming the video to disk for then to use a second program to code the stream to PSP MP4 kinda defies the purpose of "live-video" hehe..

Any ideas? I saw there was some kind of xH264 project posted on the page here, but that seemed like being a separate installation of a program, and not a codec that were aviable to use inside VLC.. (Yeah.. im a bit of a VLC newb.. Guess one may not be able to "add" codecs to VLC as they all build in perhaps?)

I have recoded a little movie i have with 2 different software.

first is ImTOO PSP Video Encoder. When i play this file with VLC i get the following stream information :
Stream0 :
Codec: mp4v
Type: Video
Resolution : 320x240
Frame Rate : 29.970030

Stream 1:
Codec: mp4a
Type: audio
Channels : 2
Sample Rate: 24000
Bits per sample : 16
Bitrate : 768 kb/s

General :
Duration : 0:01:12

Then i set theese settings in VLC under Sout Stream - Transcode (I change the resolution and such there (as the original source is different).

When i open this stream with VLC, i get EXACTLY the same as above. But, i still get "Corrupt" or "Unknown" on PSP when i try to play the file. And yes.. the file is renamed to m4v00003.mp4 and put in the \MP_ROOT\100MNV01 folder just as the ImTOO decoded one (wich works just fine).

So.. VLC reports the stream and codecs++ being exactly the same when i view the properties, but there is still differences it seems..

Could it be that the PSP somehow need a special "file-header" to recognize the video? If i open the file in a hex editor, there is differences.. Asuming the header of the file is first this is how the working file look like :

Opening the VLC encoded file, there is some huge differences :
