Quicksync doesn't work after enabling HDR Tone Mapping

4K HDR Hardware Transcode

If you are using Intel iGPU : Latest compute runtime broke HDR Tone mapping on Plex Solution : Downgrade compute runtime drivers to 21.49.21786 Install these on your Plex container and test. It worked for me

Try downgrading the intel runtime drivers to 21.49.21786, per the linked post. I had the same issue last month, and it worked for me.
