As far as I know, on P900 you can encode videos using AMR audio (8khz
mono, "phone" quality), while on P910 you can use MP3 encoding also
(much higher audio quality).
Johan "Drakonen" Otten told me he successfully encoded an MPEG4 file
with AAC audio using:
ffmpeg -i inputfile.avi -s 276x208 -vcodec mpeg4 -acodec aac -ab 28 -
r 8 -b 100 ~/p900video.mp4
My ffmpeg version (compiled from CVS source) doesn't have AAC support
(maybe I need to get some external source and add to the ffmpeg tree
before compiling); I will investigate it and let you know.
