Public bug reported:

Binary package hint: ffmpeg

I tried to convert a flv file to mp3. But this doesn't work. (Ubuntu
intrepid ibex).


koen at solar:/tmp$ ffmpeg -i Flash3uRSRn.flv -acodec libmp3lame -ar 44100 -ab 160k -ac 2 output.mp3

Seems stream 0 codec frame rate differs from container frame rate: 1000.00 (1000/1) -> 29.97 (30000/1001)
Input #0, flv, from 'Flash3uRSRn.flv':
  Duration: 00:03:34.5, start: 0.000000, bitrate: N/A
    Stream #0.0: Video: 0x0007, 29.97 tb(r)
    Stream #0.1: Audio: 0x000a, 44100 Hz, stereo
Output #0, mp2, to 'output.mp3':
    Stream #0.0: Audio: libmp3lame, 44100 Hz, stereo, 160 kb/s
Stream mapping:
  Stream #0.1 -> #0.0
Unsupported codec (id=0) for input stream #0.1


With -acodec copy I get a not working mp3 file.
