I love Plex, but I currently have some problems that perhaps you can help me solve.
Setup
PC (PMS Server): Ryzen 2600X & Nvidia RTX2060
TV: Samsung Q60T Buy Q60T QLED Smart 4K TV, 65" | QE65Q60TAUXXU | Samsung UK
Player: Chromecast Ultra and/or Plex installed as a app in the TV
Soundbar / Audio Output (via eARC): SONY HT-SD35 2.1ch Soundbar with powerful wireless subwoofer and BLUETOOTH® technology | HT-S350 & HT-SD35 | Sony US
Problems:
1080p content is played as a bliss. All that are able to be directly played (no transcoding) are also done so.
HEVC/x265 4K content (played either via CCU or via the APP) are being transcoded on the audio and the video. While transcoding the video on itself is frustrating, the end result is outwashed/greyish (lacking good color).
I’ve tried SDR and HDR files, reproducing the same error. Both are being “force transcoded” to x264.
- As neither my TV, Chromecast Ultra or Soundbar can take DTS-HD natively the audio should be transcoded - which it is, and it works great.
Tried problem solving:
-
WiFi LAN sustains 40 MB/s - far exceeding requirements in terms of bitrate. Furthermore, I tried wired connection to the TV to see if that was the issue - but it was not.
-
The movies are starting rapidly and there’s no stuttering. IMHO network is not the issue here.
The TV (and CCU) should be able to diretly play HEVC up to 80mbit/s bitrate. Is there anywhere in the logs where I can read why it starts to transcode the video?
Thanks!
