ogv.js 1.1.0 is now in alpha: https://github.com/brion/ogv.js/releases/tag/1.1.0-alpha.0
This fixes lots of little bugs, supports volume control, and has major fixes to seeking and source-switching which should be nice. Also various improvements that should work better with the experimental videojs integration.
After shaking 1.1.0 out for a couple more days, should be ok to go ahead and merge.

[WIP] Update ogv.js to 1.1.0-alpha.0
@brion ogv.js is much faster in videojs which handles streaming 480p very fast I didn't notice any drops in the video or it stoping.
We could increase the resolution for ogv in videojs due to it handling the video really better then kaultra player.
1.1.0 is tagged and released; ready to merge https://gerrit.wikimedia.org/r/#/c/286307/
