![]() ![]() I don't game on AppleTV so no info on that.Īlso FYI, when I was setting up my parent's AppleTV 4K, Make sure you are using HDR 4K rated HDMI cables and receiver (if using one) and make sure the AppleTV is running in HDR mode in video settings. I confirmed that the Plex server sends the file without transcoding to the Apple TV 4K, it only changes the underlying transport from MP4 to M2TS.įYI, AppleTV does not support DTS sound tracks so either the Plex server transcodes these on the fly to Dolby AC3 or AAC or do what I do and transcode the DTS Master audio track to higher bitrate Dolby Digital Plus version beforehand so that the server doesn't have to do any transcoding. I was a happy camper once I saw the 80+ Mbit/sec h.265 file playing back nicely again. I found out it was a buggy Plex server version and a recent upgrade fixed this issue. ![]() These are 4K rips straight from 4K disc where I used MP4tools and ffMPEG to create an MP4 muxed stream containing the original H.265 track from the disc and a Dolby Digital or Dolby Digital Plus sound track. Plex would constantly choke, stutter, pause playback on these files. The one thing I did have an issue with for a while was streaming high bitrate H.265 files to the AppleTV 4K. The recent server versions may have fixed this issue and this fix may not be needed anymore. I always conform my Handbrake encodes to H.264 High Profile, Level 3.1 or 4.1 depending if SD or HD which the recent AppleTV's handle without issue. ![]() You don't need to do this modification so long as your Plex server has enough CPU to transcode on the fly. Before I did that, Plex would always want to re-compress the file on the fly and eat up server CPU (not to mention compressing to a lesser quality). Plex works fine on both once I made a modification to the TVOS profile so that it will DirectPlay my Handbrake files.
