I last updated my gentoo node 1-2 months ago. Updated yesterday and have been trying to figure out why av1_qsv no longer works on encode.

It's been throwing errors - https://pastebin.com/sYAZ7tGy

emerge info - https://pastebin.com/4Gutqxyr

I tried downgrading the intel media drivers thinking it was an issue with them but that did not fix it.

I tried downgrading ffmpeg from 9999 to 6.0.1 and that did not fix it. Mostly because there are some issues in the ffmpeg master branch right now that cause QSV to not work (or something?).

Then I realized all of the ebuilds for ffmpeg had been updated since my last upgrade (modified). So I compiled the cartwheel version of ffmpeg and that did fix it.

https://github.com/intel/cartwheel-ffmpeg

So something in the current ffmpeg build is blocking av1_qsv encodes with DG2 cards.

Please always use attachments rather than pastebins, as they expire and/or may not be accessible behind firewalls.

I don't think we apply any patches for QSV in Gentoo, so this is an upstream ffmpeg problem. If there's a patch we can cherry-pick from upstream, we can consider that though.
