This repository is meant to provide some examples for you to better understand the features of the OpenTok iOS SDK. The sample applications are meant to be used with the latest version of the OpenTok iOS SDK. Feel free to copy and modify the source code herein for your own projects. Please consider sharing your modifications with us, especially if they might benefit other developers using the OpenTok iOS SDK. See the License for more information.
Each of the projects build on the lessons of the previous. After reviewing each, you will have an understanding of the OpenTok iOS SDK API. Additionally, you will be able to get started with writing your own extensions to the default capture implementations provided herein.
-
Hello World - This basic application demonstrates a short path to getting started with the OpenTok iOS SDK.
-
Custom Video Driver - This project provides classes that implement the OTVideoCapture and OTVideoRender interfaces of the core Publisher and Subscriber classes. Using these modules, we can see the basic workflow of sourcing video frames from the device camera in and out of OpenTok, via the OTPublisherKit and OTSubscriberKit interfaces.
-
Custom-Audio-Driver - This project demonstrate how to use an external audio source with the OpenTok SDK. This project utilizes CoreAudio and the AUGraph API to create an audio session suitable for voice and video communications.
-
Screen-Sharing - This project demonstrates how to use a custom video capturer to publish a stream that uses a UI view (instead of a camera) as the video source.
-
Live-Photo-Capture - This project extends the video capture module implemented in project 2, and demonstrates how the AVFoundation media capture APIs can be used to simultaneously stream video and capture high-resolution photos from the same camera.
-
Simple-Multiparty - This project demonstrates how to use the OpenTok iOS SDK for a multi-party call. The application publishes audio/video from an iOS device and can connect to multiple subscribers. However it shows only one subscriber video at a time due to CPU limitations on iOS devices.
Samples use CocoaPods in order to install the OpenTok.framework. You'll find a Podfile in each sample. Run pod install to fetch the framework. After CocoaPods is finished, open the generated workspace file. (Do not open the project file or the dependency with the framework will not be set)
