Server Version#: 1.43.0.10346 on Windows Server 2025
Player Version#: 10.30.6 on CCwGT on Android 14
Hi!
Recently I encountered the issue that some of my files started playing with buffering.
Digging deeper I found out that for some reason Plex started transcoding video (HEVC → H.264) at the same time it starts transcoding audio ( EAC3 → OPUS since CCwGT does not support EAC3 locally).
Both server and client are on the same local network.
Same file plays Direct HEVC when using other audio codec like AC3 or DTS.
Same file plays Direct HEVC and transcodes only audio when playing on Android mobile device (see screenshot).
No subtitles used.
I tried passthrough disabled, HDMI, Optical with or without AC3, same result.
Same file also was playing fine (at least without video transcoding) back in September.
Maybe some update broke something?
I also tried to make a custom .xml profile, but apparently Plex client tells server to ignore these profiles and sends it’s own profile instead (if I read logs correctly).
Can someone help me please?
For now I just transcoded manually EAC3 tracks to AC3, but previously automatic transcoding worked fine and I want make it work again.
Server logs attached, there are 2 devices trying to play the same file “Голый пистолет“.
Pixel 8 (Android mobile) and Chromecast (Android TV).
