Support Media Source Extensions tests

This will improve scores for browsers like Edge 14 because this is the default behavior for Edge 14 (copied from the link) :

Returns true :

isTypeSupported ('video/webm; codecs="vp9"')
isTypeSupported ('video/webm; codecs="vp9, opus"')
isTypeSupported ('video/webm; codecs="opus"')
isTypeSupported ('audio/webm; codecs="opus"')

And these will return “false”:

isTypeSupported ('video/webm')
isTypeSupported ('audio/webm')

VP9 works fine on YouTube for me at least. This kind of conflicts the results of html5test. Sorry if I blabbered something - I am not a hardcore web dev.

MSE is already included on HTML5Test

@dstorey D'oh!

Yes, we already test for the existence of MSE support. But I am interested in adding codec tests for MSE too. I already have this for the video and audio tag itself, but I suspect that codec support can differ between directly using the tags and MSE.

dstorey commented 8 years ago

Edge at least does support different codecs at the moment for MSE vs vanilla audio/video

dstorey commented 8 years ago

For that matter codecs supported by Web/ObjectRTC will be different to MSE & vanilla video element too
