Streaming video over WiFi and Bluetooth on iOS

Question

This question is going to be quite generic since I'm novice in iOS, video-streaming, and Bluetooth (going to be an interesting project).

Basically I wish to be able to stream low-res video from one iOS device to another iOS device, either through WiFi or Bluetooth depending on which one is available. Bonjour is used for initial service discovery. (I know streaming video over Bluetooth is non-ideal but it's one of the project's requirements)

So the question is what video-streaming framework/library can be used in order to maximize the amount of code shared between streaming video over WiFi and streaming video over Bluetooth.
