so at least on very new stock Android devices, all is well. My much
older Galaxy S didn't fare so well, though, so I would be willing to
believe that Android devices with proper WebM support are still
relatively rare. That said, the replacement rate for this hardware is
frequent enough that it won't be long before my Nexus 7 is "much
older".
I can play the current media on the front page of Commons in Chrome on my
Nexus 7, but it won't play in position on either desktop <

Sigh. :)
Still some work to be done on compatibility...
I also notice that the <source> elements in the <video> seem to start with
the original, and aren't labeled with types or codecs. This means that
without the extra Kaltura player JS -- for instance as we see it on the
mobile site right now -- the browser may not be able to determine which
file is playable or best-playable.
This may be contributing to the rrreeeeaaalllyyy slow performance I see on
our FirefoxOS test device -- which understands Ogg Theora and WebM but has
no hardware acceleration for them, and a relatively slow processor. If it's
pulling a 1920x1080 original to play on a 320x480 screen, it's going to be
slower than it needs to be.
