doesnt look like it has anything to do with HLS, but a few lines down you should see this:
no remuxable profile found, so video stream will be transcoded
so it seems to be a lack of a “remuxable profile” whatever that means. so uh, can you guys make that? what profile exactly is missing? seems like definitely a limitation in Plex, since the hardware can do it.
here you can see another example. with HDR tone mapping disabled to prevent the system from crashing. but you see direct play, then all transcode just from changing the audio.
is it because Plex decided to transcode the audio to EAC3 and there is no 4kHEVC+EAC3 combo available for muxing? if so, maybe plex could be a little smarter to choose an audio codec to convert to that can still be remuxed?
