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 !

The full VideoToolbox transcoding pipeline was not available in the past due to missing GPU accelerated hardware filters. But recently new developer (credit by @gnattu) have completed this to take advantage of the Metal API and the fixed-function hardware, and the prime time will be in Jellyfin 10.9 (planned to be next week if there are no exceptions).
