I have a video I need to convert to mp3 (from the command line – not GUI): video.mp4
I tried:
ffmpeg -i -b 192 video.mp4 video.mp3
with no success. I get the following error:
WARNING: library configuration mismatch
Seems stream 0 codec frame rate differs from container frame rate: 59.83 (29917/500) -> 59.75 (239/4)
WARNING: The bitrate parameter is set too low. It takes bits/s as argument, not kbits/s
Encoder (codec id 86017) not found for output stream #0.0
so I tried lame:
lame -h -b 192 video.mp4 video.mp3
I get:
Warning: unsupported audio format
Am I missing something?

For FFmpeg with Constant Bitrate Encoding (CBR):
or if you want to use Variable Bitrate Encoding (VBR):
The VBR example has a target bitrate of 165 Kbit/s with a bitrate range of 140...185.
