+ vjs.Html5.{patchCanPlayType,unpatchCanPlayType}

Browse Source 
patchCanPlayType is called on load.
It patched video#canPlayType if needed.
unpatchCanPlayType will revert the patch and return the patch function.
There are also corresponding tests that test patchCanPlayType,
unpatchCanPlayType and also whether the patch functions themselves work
correctly.
