Did you try Twitch? It indeed stops working ,and I wouldn't consider it
as niche as viewing YouTube thru Invidious (OT: I believe it's becoming
less and less niche.)

It doesn't like my VPS provider. After connecting from my home, I saw
the same thing as you: it runs on the CPU.

Raw media links:

https://img-9gag-fun.9cache.com/photo/amoz10j_460svvp9.webm (VP9)
https://img-9gag-fun.9cache.com/photo/avynegn_460svav1.mp4 (AV1)

According to about:support, both VP9 and AV1 decoding are supported
(tried with the Tiger Lake, i7-1165G7, Intel iRIS Xe-LP).

Downloading the video and playing it with MPV works wonders. Playing it
in Firefox makes the CPU usage raise. Enabling
media.ffmpeg.vaapi.enabled made no difference, even after a restart.

Basically, it seems that having an VA-API enabled ffmpeg doesn't make
a difference in Firefox right now.
