disclaimer: configuring video cards is not my strong suit, honest
Have new-to-me Dell Precision 3450 desktop I'm using as a Plex server. 10th gen i7, Intel Iris Plus graphics.
Running Unstable, I've been chasing my tail for almost a week to get hardware video acceleration working. I seem to have resolved it this morning by replacing intel-media-va-driver-non-free with the open source driver (intel-media-va-driver). This was the only change I made and it appears to have fixed things.
I kinda need a sanity check before I file a bug report; installing either driver will remove the other one so easy to recover from this experiment, but when Plex is transcoding 4k HEVC to 1080p h.264 the non-free driver will use about half my CPU resources and the open source driver cruises along at about 2% CPU use.
Can someone with a little more experience than me weigh in on this? Issue is easily reproducible.
cheers -
edit: Most of this issue was caused by my desire for Shiny New Stuff - if I'd kept the open-source driver instead of being attracted to the non-free driver I probably wouldn't have been chasing my tail for the last five days trying to figure this out. I think there may be a lesson here
