Gents,

In case I was not clear enough - my plan is to push
01-11 (prep work) - this wednesday(tomorrow)
12-16 (vdpau, xvmc)- over the weekend
17-23 (omx, cleanup)- mid next week
24-26 (xa, gbm, egl)- next week's weekend

Don't be shy to speak up, if you feel that any of the above sounds
unreasonable.

Feel free to shout at me as soon as you notice any bugs :)
