[MEncoder-users] Sony PSP compatible MP4

[Jon Drukman]

I'm trying to use mencoder to convert files to Sony PSP compatible MP4 
format.  Has anybody done it successfully?  I took a PSP movie created 
by Agility Anystream and ran it through mplayer -identify to try to get 
some clues.  Here's what it said:


Playing M4V10012.MP4.

Here's what I came up with, but it doesn't work:

/opt/mplayer32/bin/mencoder $1 -o M4V00001.mp4 \
     -of lavf  \
     -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames \
     -ovc lavc \
     -lavcopts vcodec=mpeg4:vbitrate=$bitrate:acodec=mpeg4:abitrate=56 
-vf scale=320:240 \
     -oac faac -srate 24000 -af lavcresample=24000


The PSP doesn't recognize the output file as a valid movie. Here's what 
mplayer says about the file I've created:
