I can reproduce the problem; it seems that WebGL is now a required by
youtube when using Icecat 68? That's strange because the same video
plays fine in an older version of Icecat (but I have to reload the page
to get it playing).
Anyway, the problem seems to have more to do with Youtube than HTML5
playback in Icecat. A random HTML5 video playback test site [0] may
help to convince you of such :-)
You could try enabling WebGL in your Icecat (disabled by default) by
visiting the "IceCat-specific privacy settings" of the Settings page and
checking "Enable WebGL". That didn't work for me, as my driver seems
blacklisted by Mozilla. I tried force enabling it with suggestions from
this page [1] but your link would still wouldn't be happy with my WebGL
support.
HTH,
Maxim
