(Yes, I know Rich proposed the direct-assign technique, but I'm not in favor of that approach for a number of reasons.) Instead, you convert the MediaStream into a persistent in-memory URL via URL.createObjectURL. The result is a string. So, I'm really not sure I get the "bubble events back into the parent" concept. If there were to be such a thing, the event handlers would need to be defined on the <video>/<img> tags themselves--having them on the MediaStream wouldn't do any good. > >Thanks, >-Anant >
