Apple Silicon's GPU transcoding / Tonemapping

[Thibault_GLN]

I use a Mac Mini M2 to run the server on it. I achieved a good result of fast real time transcoding using apple videotoolbox to decode and CPU to encode BUT, the GPU of the apple silicon is not used at all. I've noticed Da Vinci Resolve makes a very good job at using the full potentiel of the GPU when exporting videos. Is there someone to take the challenge of adding the GPU of apple silicon to the hardware acceleration list in Jellyfin ? (I think there is something to do with ffmpeg and Metal).

It could also be a way to make real time tonemapping possible on the ARM apple devices.

Cheers !
