Unfourtunately I've been running into trouble playing 4K HDR where the video and audio freeze but on the dashboard the timestamp continues. I have attached the logs below but I am unsure whats wrong. I'm trying to watch Joker off my Nvidia Sheild which is on the same network as my server. Both connected by ethernet and I have 500mb download(speedtested) but I dont think speed should matter as much on a local network. Plus ive been able to play movies of similar or higher bitrate before such as Aquaman. You might be able to read the logs better as Joker shouldve been the last movie in the logs. Also its direct playing. My server is a dedicate i7-4770 with 8GB and has no other apps other than sonarr and radarr, I understand the problem usually is too high bittrate but it doesn't make sense as everything should be able to handle it.
Hope this helps and I hope you can help.
