Ahhh, well, I remember like 2 years ago searching video feeds for people's heads and loading a 720p video on an olden iPad, I was able to get about 20 - 24 FPS doing on the fly face detection using the iOS 7 libs and AVFoundation. Even when using the two cameras, we were able to get a good enough frame rate.
Didn't bother trying to handle audio as well.
I think that's the case though. What's "good enough" for the frame rate?
Sounds like something fun to try, assuming the OP has vast amounts of spare time to try it out.
