Summary of the bug:
How to reproduce:
{{{
% ffmpeg -i input -c:a aac -b:a 320k -af aresample=resampler=soxr -ar 48k
... output
Output is then variable bitrate.
If I just write -b instead of -b:a 320k it creates constant bitrate but
then it defaults to 192k
ffmpeg version N-114629-g1590a96adc-20240403
built on ...gcc 13.2.0 (crosstool-NG 1.26.0.65_ecc5e41
}}}
Patches should be submitted to the ffmpeg-devel mailing list and not this
bug tracker.
