Plex on raspberry pi and docker always try to transcode video

Server Version#:1.22.2.4282
Player Version#:5.13.0

Hello everyone,

I have my Plex running on a Raspberry Pi 4 8 gb ram and its inside a Docker container. My tv is Samsung Q90T and it doesn’t support DTS audio so what I want is that plex only transcodes the audio. Both my raspberry and tv are connected to router with a lan cable. When I play a AC3 audio movie it plays without any problem but when I try to play a dts media it tries to transcode both video and audio. I have direct play enabled but when I check the logs it says direct play is disabled. When I enable option for disable video stream transcode and try to run a dts media it directly fails and says unexpected playback issue. So where can be my problem if you guys can help me I really appreciate it. Plex Media Server Logs_2021-04-20_07-12-05.zip (4.3 MB)
