Would it be hard to implement something like this in MPV? Maybe at the end of the AO line.

Do you guys have any pointers of how I can approach this?
This can't be done generally, because the AO line is shown once, while the bit rate can and does vary. There are however the properties "audio-bitrate" and "video-bitrate" which are constantly updated during playback.
You could do something like
--term-status-msg='${audio-bitrate}'
but it doesn't work on all files
