Discussed with jgilbert in matrix - not entirely sure why this is the case, but also not super surprising either.

Just to make it clear, in my testing (on Win10), I didn't see any disparity between SW or HW decoding.
h264 one (attachment 9220688 [details]) does not work, (this is already covered by bug 1709945.)
while AV1 one (attachment 9220681 [details]) works in both SW/HW decoding.

Full-range is an SDR concept, not an HDR one, fwiw.
Full-range is e.g. y:[0,255] instead of standard-range/narrow-range y:[16,235].

This item is listed as a dependancy by #1889288 but the correct matter of course is that it's possible to have flawed SDR but functioning HDR;
Getting unexpectedly important: https://bugzilla.mozilla.org/show_bug.cgi?id=1889288
So, in other words, #1889288 can be solved without first fixing this item (#1716093), so it's a false DependsOn, that may be blocking a few potential FireFox open source developers who want to contribute a lot of code. Can we un-deadlock this somehow?
