============

Turning off “Use hardware acceleration when available” in server settings fixes the issue, but this causes CPU encoding.

Playing file accessing Plex Server via browser shows same behviour.

Direct play titles work.

I am thinking the latest plex version induced issues.

Anu help?

See thread linked below.

  1. Fall back to Nvidia drivers 515.86.01.
    Reboot the server after installing the older drivers.
  2. Run PMS 1.30.2. Others have fallen back to 1.29.2.

Thank you.

Hopefully new version will fix the issue at not too distant future.

Got the same problem. Worked for me with 1.29.2 …
