Here's a wiki running the patch with some sample files:
https://ogvjs-testing.wmflabs.org/
Status update:
* Resolution switching is now available
* Automatic selection of 160p or normal-sized source based on a JavaScript
microbenchmark[1]
* Fixes for JavaScript player in iOS 7 Safari (desktop view)
* Added IE 9 support with Flash player version[2]
* Switched IE 10/11 to use the Flash version for more consistent
performance on low-end machines[3]
I hope to do some work on integration into MobileFrontend during Wikimania,
probably with a temporary lightweight UI. If interested in helping or
testing, come bug me during the hackathon in person or via IRC!
[1] The benchmark heuristic for overriding source selection logic is pretty
hacky, but gets playback working on more of my slower test devices while
usually defaulting the faster ones to larger sizes.
[2] I'm not sure if IE 6/7/8 support is possible; the player JS in
TimedMediaHandler doesn't seem to initialize. Not sure if it's blacklisted
or if I've just failed the detection logic somewhere.
[3] IE 10/11 can run the entire decoder and video playback in JavaScript
but require a Flash shim for audio; the combination of JS and Flash adds
some overhead versus running all in Flash, especially on older or slower
machines. Note that IE's developer status pages indicate Web Audio support
is "in development", so a future IE version should drop the Flash
requirement. Until then... I find decoding free formats in Flash very
satisfying somehow. :D
In the process I've noticed several issues with TimedMediaHandler and its

These are pretty much all fixed now except the
ffmpeg2theora-and-avconv-broken-in-trusty issues, which can work around.
The new job runner as provided in MediaWiki-Vagrant runs the transcode jobs
automatically, and transcodes and playback both now work running under HHVM.
Yay! Thanks to everybody who helped me with Vagrant and Labs-Vagrant.
