Server Version#: 1.16.5.1552
Player Version#: Plex for Samsung 4.5.1
I put my server on a NAS Synology DS918+ thinking it would be a good NAS for 4k streaming.
But I have constant buffering for huge movie files (50Go - UHD 4k - Atmos 7.1 - HDR 10 - HEVC)
Everything is on the same network, 1Gbit. The TV is a Samsung QLED 8k 65" QE65Q950RB.
In the dashboard it doesn’t seem I have problem with the CPU usage but if I check the verbose log, I find speed around 0.3 or 0.4 which seem to point to the CPU as the problem (can’t transcode fast enough)
The buffering problem starts instantly as I start the movie.
You’ll find the logs attached, hope it will help. If I have to provide something else, let me know.
Thank you very much

Sorry for the verbose, I will definitely turn this option off. I was using it following the help on plex website and forgot to turn it off and make a new log.
For the subtitles, I’ll use the plex feature to get subtitles in srt. Thanks for the info.
For the audio, I already have an Anthem MRX 1120 but I don’t have the speakers. Will definitely use passthrough when my system is up and ready. Thanks again for the info.
For the video transcoding/direct play, I’ll try to use Handbrake to have a compatible format for my TV if changing the subtitles doesn’t help much.
