Allocate different GPU's to different codecs for decoding

I highly doubt this can happen any time soon. My understanding is that this is a limitation of ffmpeg and how ffmpeg calls devices via QSV/NVENC/AMF.

FWIW, the check boxes under Dashboard > Playback are for DECODING. If you leave them unchecked your CPU will decoding them. VC1 is pretty uncommon as is VP8. MPEG2 is simple to decode coupled with it being used with lower res DVD content, there isn't much of a load on the CPU to decode it.

Jellyfin will ENCODE to a limited set of video codecs. H264 and HEVC in the current version. AV1 when 10.9 is released.
