Hi Tim,

I'll look into trying that if I have to use multiple playbins.

Is there an alternative way to use all of the equivalent functionality
of playbin without creating multiple playbin elements? It seems like
every other way of creating an individual stream involves a ton of
boilerplate, which is why playbin is appealing to me.

It seems like it would be nice if there were an element that was roughly
equivalent to the current playbin that was actually a bin, and not a
pipeline. Perhaps the current playbin element could be refactored to
hold such an element as its only child.
