I recently made a video post using a link that I got from xcancel on a Twitter post. I can see the video when viewing from Lemmy, but when using PieFed, Voyager, and Blorp the video does not load.
The post I’m referring to:

Edit with working link:

With Firefox on Android (even if asking for desktop version of site, then for good measure reload page) I get the same error that you did for LibreWolf, "No video with supported format and MIME type found.”
And I also get the same behavior for Chrome (on Android) as you described for Chromium on desktop.
I hope this helps a little.
