It’s a brand new deployment of a Plex server as I’m migrating systems. Added one movie. Attempted to optimize the movie. It gets added to the queue and then just sticks on “waiting” forever. Confirmed Plex has access to the content since it was able to create the “Plex Version” folder structure. It just never converts the movie. System has a Arc A380 via PCI passthrough on pve 9
Plex server on Ubuntu 24.04.3 LTS
Server Version#: 1.42.1.10060-4e8b05daf
Player Version#: 1.110.0.351-4e48eb83

Check Settings → Transcoder → Maximum simultaneous background video transcode.
If Unlimited, change to anything else and Save Changes.
There is a bug in 1.42.1.10060 that blocks background transcodes when the setting = Unlimited. There is separate bug where HEVC optimizations may have no video.
Both bugs are fixed in the current beta, [1.42.2.10102](https://forums.plex.tv/t/plex-media-server/30447/688):
- (Downloads) Setting ‘Maximum simultaneous background video transcode’ to ‘Unlimited’ would prevent any download transcodes or optimizations from running (PM-3957)
- (Optimizations) HEVC Optimization could result in a file with no video (PM-3938)

To add to FordGuy,
There currently is no Intel ARC GPU support in PMS.
We will be updating the Intel Media Drivers, which should bring us the new GPU support after FFMPEG 6.1 goes live (shortly)
