Not just MAC, Its happening on Windows & Linux too. Subtitles being transcoded from .SRT to .ASS are causing really high CPU usage. Not just a coincidence all OS are seeing this issue. Must be something that was either fixed/broken in one of the latest updates.
I can confirm this issue. I am running similar set up to OP. Intel Core i7 8559U processor with Quick Sync, using the Docker container. Hardware encoding on. This particular stream is SRT and it’s converting to ASS. 100% utilization of 1 logical CPU.
I have captured logs with Verbose + Debug turned on. I am happy to provide it so you can forward it to your engineering team. Just say the word.
Running Ubuntu 18.04, and Plex Server 1.15.4.993. Please continue to keep us updated on any response b…
Happy to know I am not alone with this issue. I too noticed today, that sometimes if someone plays something on Xbox, a transcode will appear with .ass subtitles, even if it can direct play it. As soon as I terminate the stream and my friend picks it back up, it will direct play.
But same issue, as soon as the .ass subtitles appear, one core will idle at 100%… Hoping for a fix!
Just FYI, I’m not using docker and I’m seeing the same behavior. I just think it goes unnoticed because I assume most people don’t use the Web-player. However, I think this triggers for any platform that need subtitles converted.
I think it might be better do downgrade to 1.15.2 to avoid this problem.
