Dumping Audio stream from flv (using ffmpeg)


There are 7 alternatives - vote for the best!

Terminal - Alternatives
ffmpeg -i video.avi -f mp3 audio.mp3
ffmpeg -i input.flv -aq 2 output.mp3

Gives stereo, 16bit, 44.1kHz (default in Ubuntu/Medibuntu ffmpeg).

-aq 2 = 220-250kbit/s VBR, lower number is better quality. 2 or 3 should be good for most people. If you want the best mp3 q you should remove -aq and use -ab 320k to get 320kbit/s, but that is probably overkill for most .flv videos.

Know a better way?

If you can do better, submit your command here.

What others think

what will be the setting for mp3? it seems abit missing parameters... what kbps? ar? etc...

While posting I included an example in the summary box, but didn't get reflected, It will be the default values(for -ar, -ab, -ac etc) configured in ffmpeg, I can remember 64 kb/s is ffmpeg's default audio bitrate.
