I just found a 10 second ideo on this page which does at least play.
It's silent, however:

Could the absence of sound be significant? Has anybody tested whether
Wayland is the problem? Can't remember if I'm using Wayland or X11 at
the moment...

I guessed as much. I  was wondering if the _lack_ of audio in the
file might have something to do with why it played in chromium.
It was the first "no audio" file I encountered since the trouble
started.

 
 
These ones do:

That one doesn't play, beyond opening an empty window.
The run timer stays on 0.0, but the progress arrow
momentarily starts, then retreats, when the play arrow
is clicked.

Same empty window, no progress arrow at all.

Not sure what to make of these observations.

Is there a command to indicate whether the system is running
wayland or x11? I thought there might be some hint in the
dmesg output, but I don't see anything:
dmesg | grep -i wayland
yields no output,
dmesg | grep -i x11
reports

which doesn't look relevant, at least to me.

IIRC, some earlier trouble emerged when using Wayland, which motivated
the use of x11. Now I don't remember which is in use.....
