High CPU usage after 1.15.8.1163 update

Plex Media Server process uses 100% cpu (SRT->ASS Conversion)

Hi, Server Version#: 1.15.3.876 (docker/plexpass) Player Version#: 3.95.1 I’m seeing 100% CPU usage of the Plex Media Server process only when something is playing. It’s using hw transcoding when needed and it works well, eg 4k -> 1080. CPU is Intel(R) Core(TM) i7-7567U CPU @ 3.50GHz with QuickSync available. This is with one stream in direct play (I usually can go to 4 to 5 transcoded streams in parallel without any problems): [image] As you can see, the transcoder isn’t doing much but …

Are you converting SRT subtitles to ASS? There’s been a bug for months they won’t fix. You have to roll back to a build from December to fix it. Roll back to Plex Media Server 1.14.1.5488 and it will be fixed.
