When attempting to begin the broadcast the stream stops immediately after publish begins. I know that the server is accepting streams because I’ve been able to connect to the wowza server with the Android SDK and I’ve connected to it with VideoCore for iOS as well.
The VideoToolbox error (-12902), according to Apple is kVTParameterErr
Permissions seem to be set up correctly. The preview displays, the flashlight toggles, and the camera switches front-to-back correctly, I just can’t initiate this broadcast.
Log Output:
```auto

Any ideas on this? I’d really rather not have to use a different broadcasting tool for iOS from Android.
