Hi,
I have an ffmpeg command that I use to down size video for the Sony
PSP. the oddity with the psp is that it requires audio to be in mp4
format. you need a relatively recent build of ffmpeg, but the
following works:
ffmpeg -y -i INFILE -bitexact -f psp -s 320x240 -r 29.97 -b 768
-acodec aac -ac 2 -ar 24000 -ab 32 M4V10001.MP4
I haven't been successful converting to a wide screen format, but the
psp has a full screen option and since it is a widescreen natively,
the widescreen content looks fine. one thing to note though is that
even if my source file has a frame rate of 24.xx if I don't change it
to 29.97 for the psp I get major audio sync problems.
I'm able to get an hour show sans commercials onto a 256mb memory
stick with pretty good quality. I believe 768 is the highest bitrate
the psp will accept.
