[whatwg] Scripted querying of <video> capabilities

[Kristof Zelechovski]

What is the advantage of using JavaScript to determine a viable embedding
method over using alternative streams and fallback content that can include
the OBJECT element where appropriate?

The reason this is needed, as opposed to using multiple <source> tags,
is because inevitably, some clients will support certain formats via
<object> (or in our special case, <applet>) and not via <video>.
Querying the browser's <video> capabilities allows JS to decide what
sort of embedding method to use. It's an essential migration feature.
