It seems that any kind of transcoding is broken when the Video is using Dolby Vision with Profile 5 (Dolby Vision with higher profiles seem to work fine). Even when only the audio should be transcoded, it still tries to transcode the Dolby Vision video for some reason. In my case I’m using an Optical SPDIF/Toslink audio output, so audio gets transcoded almost for every movie, making all DV with Profile 5 unplayable. Why is this happening? Is there some way to fix this? Is this a known bug in Plex?
Here are the logs from Plex when trying to open a Dolby Vision with Profile 5 from my Android TV:
