The hardware acceleration is available immediately for media playback. Select a valid hardware acceleration option from the drop-down menu, indicate a device if applicable, and check Enable hardware encoding to enable encoding as well as decoding, if your hardware supports this. Hardware acceleration options can be found in the Admin Dashboard under the Transcoding section of the Playback tab. QSV uses a modified (forked) version of VA-API and interfaces it with libmfx and their proprietary drivers (list of supported processors for QSV).
VA-API is a Video Acceleration API that uses libva to interface with local drivers to provide HWA.
FFMpeg and Jellyfin can support multiple hardware acceleration implementations such as Intel Quicksync (QSV), AMD AMF, nVidia NVENC/NVDEC, OpenMax OMX and MediaCodec through Video Acceleration API's. Jellyfin supports hardware acceleration (HWA) of video encoding/decoding using FFMpeg.
