This is awesome, thanks!

I've tested it with rpi-ffmpeg as well, and it works great (only 
required one interesting logic change..

Any chance we could get 10-bit support soon as well?

10-bit is massively popular with AV1, especially with home encodes (see 
e.g. https://wiki.x266.mov/docs/encoders/SVT-AV1#encoder-optimization 
and the ab-av1 tool's defaults)


Thanks,
