I was able to play the WebM file of the locomotive on the front page of https://commons.wikimedia.org just now on my Nexus 7 using Chrome, 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 < http://en.wikipedia.org/wiki/Serge_Haroche%3E or mobile < http://en.m.wikipedia.org/wiki/Serge_Haroche%3E ...
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.
