Enabled 720p and 1080p .ogv output, using existing variable bitrate configuration:

This will enable new generation of high-definition .ogv transcodes for files whose sources are high-definition. The files will be smaller than they would be at constant bitrate, running somewhere from 'about the size of existing webm' to 'up to 40% larger than webm' depending on which configuration the webms were generated against. :)

Disabled forcing of audio output to max 44.1 kHz for .ogv output due to bugs in the resampling leading to a/v sync mismatch on long videos:

Once existing .ogv transcodes are redone, this will fix a/v sync drift on the .ogv versions of longer videos with 48kHz audio, such as https://commons.wikimedia.org/wiki/File:Knowledge_for_Everyone_(no_subtitles).webm

In the next week I'm going to try to finish up a couple more things:

Update ogv.js to 1.1.2 release (just released alpha.7, probalby final):

I've made major improvements to ogv.js on slower machines, with better audio/video sync maintenance and more effective use of multiple CPU cores. This should improve performance on old 32-bit iOS devices as well as older Windows machines running IE.

I'm replacing several half-working maintenance scripts in TimedMediaHandler with a new one that actually works. Once I've added a 'throttle' mode I'll commit it, and we can bulk re-run transcodes in production to update things to current configurations.

Transcode settings other than the HD .ogvs are currently specifying constant bitrates, which are higher than they need to be for a lot of material in order to provide enough headroom for high-complexity scenes. A cleaner variable bitrate configuration will save space on most material, while using more bits only when needed. (That will free up more space for the HD .ogv transcodes.)

...And then try to finish up more of the video.js front-end with TheDJ and anybody else who's interested. We're so close! And that'll get us video on mobile as well... :D
