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.
