#4078: Specify audio bitrate per-channel -------------------------------------+---------------------------------- Reporter: Haravikk | Owner: (none) Type: enhancement | Status: open Priority: wish | Component: ffmpeg Version: git-master | Resolution: Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+---------------------------------- Comment (by Cameron): I was having this issue today. Would be great to support this basic feature. The default for libopus uses this behavior to set the default bitrate: https://git.ffmpeg.org/gitweb/ffmpeg.git/blob/refs/heads/master:/libavcodec/... For example libopus could re-purpose the 'global-quality' that is currently unused: https://git.ffmpeg.org/gitweb/ffmpeg.git/blob/refs/heads/master:/libavcodec/... Either-way, having a 'base_bit_rate' would be wonderful for making life more simple. Another example, but not so great, is `opusenc`, it allows you to over- specify the quality, as the number channels change, it will still encode at max quality... `opusenc --bitrate 2048` sets the maximum quality... but it will max out at around ~255 /channel internally... -- Ticket URL: <https://trac.ffmpeg.org/ticket/4078#comment:4> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
