For an HEVC video I changed the audio to AC3 in Plex app on Apple TV 4K and now it atleast starts playing but errors out because transcoding crashes trying to transcode HEVC to H264. It seems it wont direct play/direct stream video of an mkv container of an HEVC file. Is there a way around this like by adding an mkv line to the tvOS file? Has anyone tried that? I really don't feel like re-encoding/remuxing my 4K videos.
Also, for 1080p h264 videos with AAC audio, plex is transcoding audio to EAC3 and therefore crashes transcoding as well because Im running on a pi 3. Shouldnt it direct play/stream the audio of AAC? Why would it decide to do transcoding when it doesnt have to? I have no idea how to get around this either. I should mention I never had this audio problem with my old apple tv 4th gen.
Right now I can't even use Plex for anything on my new Apple TV 4K :(
