Keyboard-Cat-Publisher

A silly demonstration of the OpenTok iOS SDK Video Drivers

Usage

OpenTok.framework

Download the OpenTok SDK for iOS, version 2.2.0 to the root of this repository:

curl -L http://tokbox.com/downloads/opentok-ios-sdk-2.2 | tar xj

The paths might not link automatically, so make sure that OpenTok.framework is at the root, not just the distribution tarball contents:

OpenTok Session Credentials

In ViewController.m, you will need to set an API key, Session ID, and Token in order to connect and realize the full power of the Keyboard Cat Publisher. See the notes in the source for more information.

How It Works

Check out MovVideoCapture.m to see the internals of the video capture. In this example, we decode H.264 from the .mov with the AVAssetReader interface, pass the decoded frame to the OpenTok OTVideoCapture.videoCaptureConsumer receiver, and the SDK sends the media to the session. At this time, there is no way to send pre-encoded frames directly to the session, so this extra decode-encode cycle is an unfortunate necessity.

NB: Audio not supported in this example. The app will simply send audio from the device microphone.
