I was able to play the WebM file of the locomotive on the front page

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. :)
I think this relates to the page not being purged after the transcodes
are updated. If you purge the page, will probably give the nexus a more
playable flavour.
http://en.wikipedia.org/wiki/Serge_Haroche should work on your nexus now ;)
TMH should add page purge to the job queue, but not sure why that page
had not been purged yet.
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.
For correctness we should include "type". But I don't know if that will
help, the situation you describe.

But certainly will help in the other ways you outline in the bug 43101
AFAIK there are no standard source tag attributes to represent device
specific playback targets ( other than type ), so we set a few in data-*
tags and read them within the kaltura html5 lib to do flavour selection.
We of course use the Kaltura HTML5 lib on lots of mobile devices, so if
you want to explore usage in the mobile app happy to support. For
example including the payload into the application itself ( so its not a
page view time )
