[FFmpeg-devel] [PATCH] avcodec/nvenc: add AV1 encoding support

Due to lack of any kind of compatible hardware, I cannot test this yet.
Hence I've marked it as experimental, and am submitting it in the hopes of
someone with compatible hardware showing up to give it a go.
I've tested that it compiles, and gave all the options a good look to make
sure they a) still exist and b) make some sense with AV1
It is very likely that this will not work as-is, so I'm unsure if it should
be applied as experimental, or if I should wait until I or someone who can
test gains access to compatible hardware (right now only the RTX 4090 is
available, which obviously is not a sane choice for various reasons).
