[FFmpeg-devel] Constant quality for videotoolboxenc on M1

[Nomis101]

Hi,

back in January it was asked if it would be possible to add constant quality encoding for 
videotoolbox on macOS to FFmpeg. Later, somebody provided a patch.
http://ffmpeg.org/pipermail/ffmpeg-devel/2021-January/274989.html

Would it be possible for somebody to take a look into this? Not only would it be a great addition to 
videotoolbox video encoding, it would also help to reduce the amount of patches from the internal 
FFmpeg patchset of HandBrake (the one for b-frames and the one for constant quality).

Thank you very much.
