  1. Enabled HW transcoding
  2. Tried to open a Movie with Auto Converting On
  3. I can see in the logs

It happens every time, transcoding doesn’t work. Logs archive attached

Plex cannot transcode Dolby Vision media.

On Linux based systems, Plex does not support transcoding HDR media using AMD GPUs.

Processor: 2-core AMD Embedded G-Series GX-215JJ Radeon R2E

I could not find any info online regarding supported video codecs for Radeon R2E graphics.

You might try 480p/H.264 video and see if that works.

This processor is capable of decoding HEVC(h.265), you can see it here:

I understand that DV is not supported, however the error message appears to have nothing with it and depend on completely different fault (in the container distribution probably?) which prevents amd gpu to even try to transcode

Which OS distro and version base please ?

Thanks for the info on the system.

Plex Media Server 1.32.5.7349 added support for AMD GPUs, but only for SDR media.

It also added the ability to manually select the GPU in Settings → Transcoder + Show Advanced.

Plex Media Server 1.32.6.7468 adds support for additional AMD GPUs.

The log files show attempts to transcode 4K HEVC video, which, given the file name, appears to be HDR.


Can you select the GPU in Settings → Transcoder?

If not, consider trying the latest beta which supports additional AMD GPUs.

Also, test transcoding using 1080p (or lower resolution) SDR media, whether H.264 or HEVC. Plex does not support HDR media w/ AMD GPUs, and the specifications you linked state “Playback of 2160p videos is not supported.”
