Iphone QTVR (QuickTime Virtual Reality) support

I'm planning to write iPhone app which have to be able to play QTVR (QuickTime Virtual Reality) movies (it'll be one of its core features). I know there are couple of apps capable of doing it, thus I'm wondering if there is any library available that supports playing such content开发者_StackOverflow社区?
