Comment (by sysrqb):

 I get a few errors in the logcat while testing on an emulator running API
 level 19, but the end result is the video element displaying a message
 saying "The media could not be played" - so this is better than crashing.
 This is testing the twitter video in the description.

 With the Azure reference, when I go to the Azure HTML5 player (DASH) and
 press play the script basically hangs. I don't know what it's doing, but
 the browser shows the unresponsive-script dialog but the video player
 never plays the video, and I see a lot of:
