Dispatch Queue

[iosdec]

The app crashed when running the SetupAVCapture function.

To fix, replace:
self.videoDataOutputQueue = dispatch_queue_create("VideoDataOutputQueue", DISPATCH_QUEUE_SERIAL);

With:
dispatch_queue_t temp = dispatch_queue_create("VideoDataOutputQueue", DISPATCH_QUEUE_SERIAL);
self.videoDataOutputQueue = temp;

Thanks @declanland ! I was struggling as to how to make the sample work and you just saved my day!
