--- Begin Message ---Package: libavcodec54 Version: 6:9.10-2 Severity: normal Hi, I recently noticed something weird, but I'm not sure if it's actually a libav bug (it doesn't happen with ffmpeg though). I noticed this while using mpv's encoding facility, but it happens when using avconv as well. So, basically, when I encode an audio file using libav's libmp3lame encoder, and set a default bitrate (-b:a 320k), and then run the file command on it, the printed bitrate is always "64 kbps" even if the file is, in fact, 320 kbps. To reproduce: * Generate an audio file (you can also use another audio file, it doesn't change anything): $ sox -n noise.wav synth 00:05 whitenoise * Convert the file using avconv: $ avconv -i noise.wav -c:a libmp3lame -b:a 320k -vn noise_avconv.mp3 * Run file on it: $ file noise_avconv.mp3 noise_avconv.mp3: Audio file with ID3 version 2.4.0, contains: MPEG ADTS, layer III, v1, 64 kbps, 48 kHz, Monaural You'll notice that the "64 kbps" doesn't match the "-b:a 320k", but the *.mp3 file *is* 320 kbps (the size of the file match and mp3info reports the correct bitrate). The same doesn't happen when using ffmpeg: $ ffmpeg -i noise.wav -c:a libmp3lame -b:a 320k -vn noise_ffmpeg.mp3 $ file noise_ffmpeg.mp3 noise_ffmpeg.mp3: Audio file with ID3 version 2.4.0, contains: MPEG ADTS, layer III, v1, 320 kbps, 48 kHz, Monaural Since mp3info reports the correct bitrate on both files (and the file are indeed 320 kbps), this may very well be a bug in file... but why doesn't the file encoded using ffmpeg have this problem? Also, yes, the libmp3lame is the same used to build both libav (installed from Debian archive) and ffmpeg (manually built) and this happens with avconv and libavcodec55 from experimental as well.
