Does this imply overloading createObjectURL() to accept a MediaSource
object?
A new URL is created every time createObjectURL() is called, so one might
have multiple URLs pointing to the same MediaSource object. Does this pose
any problems?
Does it make sense to just add getURL() to MediaSource instead?

3. Assign the blob URL to HTMLMediaElement.src.

What happens if the URL is associated with multiple HTMLMediaElements?
Sharing data might be nice, but what are the implications for
implementations?
