Comment 16 for bug 365514

Now I remember why I didn't use ffmux_psp... it dies with a floating point exception for whatever reason. I just tested GStreamer's latest release and their own internal libavcode/libavformat and we get the same issue. I'm not sure if Arista can output for the PSP until this gets fixed, unless there is a way to do it with the normal ffmux_mp4 or qtmux elements.

To see if this is even a viable path to take, could you try this:

ffmpeg -i myfile.foo -f psp test.mp4

You'd need to apt-get ffmpeg and run that, then see if it plays on your psp. It seems to force MPEG4 and AAC instead of H.264, so maybe there is hope yet of making this work using ffmux_mp4, faac, and xvidenc.
