Package: ffmpeg
Version: 3:20070719-0.0
Severity: normal
Hi,
The current version of ffmpeg from debian-multimedia testing repo
(v3:20070719-0.0) doesn't allow me to set audio bitrate:
$ ffmpeg -i test.avi -vn -acodec ac3 -ac 2 -ar 48000 -ab 192 -y test.ac3

Seems stream 0 codec frame rate differs from container frame rate: 23.98
(65535/2733) -> 23.98 (2997/125)
Input #0, avi, from 'test.avi':
Duration: 01:25:05.4, start: 0.000000, bitrate: 1147 kb/s
Stream #0.0: Video: mpeg4, yuv420p, 656x272, 23.98 fps(r)
Stream #0.1: Audio: mp3, 48000 Hz, stereo, 32 kb/s
Output #0, ac3, to 'test.ac3':
Stream #0.0: Audio: ac3, 48000 Hz, stereo, 0 kb/s
^^^^^^
Stream mapping:
Stream #0.1 -> #0.0
Error while opening codec for output stream #0.0 - maybe incorrect parameters
such as bit_rate, rate, width or height
I've been using the ffmpeg's -ab option for several years without
problem, and the option is still there:
$ ffmpeg | grep -2 -- -ab
AVCodecContext AVOptions:
-b <int> E.V.. set bitrate (in bits/s)
-ab <int> E..A. set bitrate (in bits/s)
-bt <int> E.V.. set video bitrate tolerance (in bits/s)
-flags <flags> EDVA.
If I omit the -ab option, then it works:
$ ffmpeg -i test.avi -vn -acodec ac3 -ac 2 -ar 48000 -y test.ac3
[...]

However, it will fail even if I set the -ab option to its default value:
