YouTube (see URL). Mac OSX 10.7. Setting the video to 480 lines gives a resolution of 859x480 so we may need to crop the RHS of the output image or something. I can also reproduce it on my MacBook Pro with a GeForce GT 330M.

I verified that this fixed the video problem I reported in duplicate bug 1151291.

Jean-Yves: should we uplift this fix to Aurora 39 or Beta 38? AFAIK, we plan to ship MSE for YouTube on OS X in Firefox 38.

Part2. Properly calculate cropping value

Approval Request Comment
[Feature/regressing bug #]: 1147744
[User impact if declined]: Image displayed may shows invalid pixels
[Describe test coverage new/current, TreeHerder]: Minimal testing, ensuring that it didn't introduce obvious regressions and testing against values returned by WMF.
[Risks and why]: Low, this is more closely implementing the H264 specs and fixes a invalid default value
[String/UUID change made/needed]: None

This code path wasn't activated on Mac (and still isn't by default) so not really a regression

Taking it in case we decide to do something with MSE under Mac.
Should be in 38 beta 4.
