Demuxing/Encoding .pmf (PSP) video files

[Cyber Akuma]

Now, I know these are Linux tools, but im using Windows 2000. Also, this is my first time using mplayer and mencoder (normally I use vdub mod).

Ok, this one is driving me crazy, im trying to encode the intro of a PSP game, I got the video file off the disk but I am having trouble converting it.

It appears to be a h264 video stream and an (by my best guess) ATRAC3 audio stream (AAAARRRGGGHHH) muxed within some type of modified mpeg-2 container.

Using mplayer I was able to attempt to dump the video data successfully, problem is it was dumped as a raw h264 stream. I have tried my best to mess around with mencoder and try to put it in an avi container, but while it works if I use raw output or re-encode, it dosent work if I just attempt to put the raw stream into an AVI container. The original h264 quality is already pretty much perfect and the filesize is decent as well, how can I just put this stream into an avi container? I don't want to re-encode it.

As for the audio, I am COMPLETELY clueless. To be honest, im not even 100% sure if it is AC3, or if it is that its being extracted correctly. I have had problems like this before with the PS2's MPEG-2 format (.pss) where video streams werent a problem to extract but audio was a real pain. Regardless, nothing I tried seems to be able to play it or even analyze it, and mplayer crashes attempting to play the muxed version, but has no trouble palying the video if I extract it, audio it can't even touch however.

If you managed to play it with MPlayer then contact me. I already made up a small batch file that, when given the correct command line parameters, converts any video (that MPlayer can play) into an XviD+MP3 codec AVI, with MEncoder's help.

Err, I already said that I have no problem re-encoding it into a playable AVI, but that would lead to quality loss, the video is already h264 and very high quality for a small file, I dont want to re-encode it.

Then you can use the "-ovc copy" option of MEncoder to keep the video stream as is.

I tried that

"mencoder.exe raw.264 -of avi -ovc copy -noskip -ofps 29.97"

The resulting AVI is unplayable in just about everything but mplayer.

Can you send me a sample (at most, a few Megabytes) in a (zipped!) E-mail attachment?

My question is- why do people use these bizarre file formats for audio and video? I mean -for crying out loud- convert it for us- you know we are leeching script kiddies!

[Cyber Akuma]

Umm..... thats the format that the game itself uses......
