Description Jean-Yves Avenard [:jya] 2023-03-02 22:47:23 PST 
With a ManagedMediaSource, it can indicate to the JS Player when to start appending content and when to stop.

The initial ManagedMediaSource implementation will emit `startstreaming` when there's less than 10s of buffered content ahead of currentTime and will emit `endstreaming` when 30s have been buffered.

When we get to 10s left again, `startstreaming` will be refired until 30s more is appended to the ManagedMediaSource
