4K HDR Hardware Transcode

Plex Media Server
36

I’m sorry but I’m not sure what else to tell you. I run Plex through the Linuxserver docker in Unraid and when trying to play 4k HDR content it would try using the iGPU to transcode. After about 15-20 sec it would fall back to CPU (Core i7-9700k). As soon as I turned off Enable HDR ton mapping it played fine (with the exception muted colors). After hours of trouble shooting the only thing that fixed it was rolling back to a previous version as ysargon suggested.
