HI, I tried to transcode an MPEG2 file to MPEG4 using ffmpeg using the following: ffmpeg -i <MPEG2_FILE_NAME> -f avi -vcodec mpeg4 -b 800 -g 300 -bf 2 -acodec mp3 -ab 128 foo.avi But it fails because it says mp3 codec is unsupported. I am using whatever ffmpeg is available from the repositories (universe / multiverse for Ubuntu 5.04 AMD64) Can anyone tell me what I should do? Is there some missing file that has to be installed for ffmpeg to work with mp3, or do I have to apt-get remove and then compile it myself with the mp3 flags? Craig
