I've been able to get ReplayKit Live to broadcast using an iPhone SE. However, it doesn't seem to be working on my iPad Mini 2. Both are running iOS 10. Are only certain devices able to broadcast?
From the code side, calling startBroadcastWithHandler: calls the completion block without any errors, so I would expect the broadcast to work. I've tested it with both Mobcrush and Periscope as the service. Mobcrush just doesn't seem to start the broadcast, Periscope seems to start it, but no stream gets pushed to it. In both cases, my RPBroadcastController instance returns NO for isBroadcasting after I start a broadcast.
