I couldn't find any good documentation on StageFright, and I didn't get much by looking through the code. Supposedly StageFright is pretty buggy, so it makes sense to use OpenCore for the time being (maybe Gingerbread will address some of the problems).
I'm sort of surprised that Android doesn't support this stuff out of the box. Maybe they will add support for HTTP Live Streaming or at the very least invent their own live streaming protocol.
