E.g. the main page delegating communication to someone else (perhaps via
an iFrame). If the MediaStream is a transferable object the incoming
MediaStream can be transferred to the main page, which in turn can
control layout and rendering.
One interesting thing about a MediaStream is that it's got multiple
links to the world around it. In particular, it can be connected to
multiple downstream objects.
This means that what happens to its peers when one transfers it has to
be defined.
For instance, if MediaStream were transferable, could I do this?
GetUserMedia(....., success, failure)
function success(stream) {
myVideoTag.srcObject = stream
stream.transfer(myWorker)
}
and after this - would the video stop playing (because the stream is
gone from my context), or not?
