Just for fun, I decided to run an optimize session. It ran for maybe 90 seconds and I was able to trace it in webmin before the sequence described above happened again. Here’s a screen cap of the trace: [tracing the transcoding process 2020-09-08 01] Unlike the first time, I am not able to ssh …

Is that CPU overheating ? It looks like either the ethernet adapter driver or the i915. May I see the full logs ZIP please, preferably a set where this is captured? Also, may I see the journal kernel logs for the event? This looks very much like a hardware issue but also could be a bad kernel …

Happy to get those to you - where can I find them?

Kernel logs are sudo journalctl -xe > /tmp/kernel.log After it writes out the log to the file, Please open in a text editor and delete all the old and unwanted entries (those logs can get big). You probably want to start at the bottom of the file and work backwards. When you find what y…

THanks, I see it now. Check the video, I’ll bet it is HEVC HDR (10 bit). The i7-6700 can only do HEVC SDR (8-bit) in hardware. HDR (10 bit) is first available in the Kaby Lake (-7xxx processors). I had a 6700 and it was pain. For me, it would fault and throw fits like nobody’s business.

Indeed it is. I have seen on the dashboard where 10-bit HDR was tagged as being HW transcoded… which left me scratching my head (because I was aware of the 8-bit HDR limitation on the 6-series Core I7). Shouldn’t Plex fall back to transcoding it in software then? Seems like Plex is not sending the…

Thanks Brad, I am writing that up. It should know better than to attempt hardware transcoding of HDR on a 6700. I wonder if the test frame it uses is a SDR frame. If so, that would explain what’s happening. Can you please provide me the XML (media part only) for inclusion in the trouble ticket…

Thanks Chuck. Thought I was going crazy there.
