and man ffmpeg:
· You can transcode decrypted VOBs:
ffmpeg -i snatch_1.vob -f avi -c:v mpeg4 -b:v 800k -g 300
-bf 2 -c:a libmp3lame -b:a 128k snatch.avi
This is a typical DVD ripping example; the input is a VOB file,
the output an AVI file with MPEG-4 video and MP3 audio. Note
that in this command we use B-frames so the MPEG-4 stream is
DivX5 compatible, and GOP size is 300 which means one intra frame
every 10 seconds for 29.97fps input video. Furthermore, the audio
stream is MP3-encoded so you need to enable LAME support by
passing "--enable-libmp3lame" to configure. The mapping is
particularly useful for DVD transcoding to get the desired audio
language.
NOTE: To see the supported input formats, use "ffmpeg -formats". | h*******t
