    Jellyfin in Synology docker has a very high CPU usage during HWA

    Suspect that hardware acceleration is not using the GPU correctly

    Hi! I got a DS720+ to run Jellyfin on it. CPU is Intel Celeron J4125 so I believe it has a GPU inside. I upgraded my jellyfin recently to 10.10.3 and I mapped the devices for hardware acceleration in docker compose file, everything should be prepared and I enabled QSV as my way to do HWA. The video can "start" to play but the transcode speed is just horrible (basically the speed that cannot play) and the CPU usage is always closed to 100% during transcoding. I expected 30%~ CPU usage if the transcoding is using GPU correctly instead of using CPU. Any help for this? I checked the logs from Jellyfin and I don't see any errors. I will put jellyfin-ffmpeg's logs here. 

    I tried QSV and VVAPI, non of them are working "correctly". They are all landed in same situation.

    Jellyfin: 10.10.3
    Device:  Synology DS720+, DSM 7
    environment: Docker
