Hi again ChuckPa.
Problem solved!!
I simply followed MrSliff’s solution on this topic and it now works!!
HDR tonemapping enabled, and here is an HDR to SDR transcode… Using hardware!

Just for fun, I tried to start 10 of those streams (which was totally impossible before, as a single stream being transcoded drained all of my CPU) and of course, it works flawlessly since it’s now using the iGPU!
CPU being super chill while 10x HDR → SDR transcodes are going on…
Anyway, thanks a lot to both of you for your help on this topic, it helped me as well!
Tip for anyone who will try to follow MrSliff’s solution on this topic: don’t fret if the make -j8 command shows a lot of warning in the CLI, just go ahead with it and it’ll work just fine.
Damn, I’m happy. Thanks again to everyone!
EDIT: Just for being precise, I’m running Ubuntu Server 20.04.3, so this solution applies to Ubuntu versions beyond 18.04 somehow!
