Steps to reproduce:
The API used by https://bugzilla.mozilla.org/show_bug.cgi?id=1853448 has the narrower range of supporting hardware decoders than that used by Chrome.
The GPU in i7 9700 partially has the support of the HEVC playback via QSV.

However, Firefox Nightly can't play HEVC videos like Edge unlike Chrome.
I've not purchased the HEVC video extension.
Reproduction steps:
- Use a older Windows 11 PC with older CPU (e.g. 9th Gen; 11th Gen can play via the current API) and uninstall the HEVC video extension if it has been installed
- Visit http://tests.caniuse.com/hevc or https://codepen.io/danm8675123/pen/abNavqG
- Try playing the video
Actual results:
Can't play HEVC
Expected results:
Can play HEVC
(Chrome has already been able to do)
(11th Gen i7 1165G7 can do via the current API)
