Live streaming with real-time video filters using the Wowza GoCoder SDK

Live streaming with real-time video filters using the Wowza GoCoder SDK™

This sample code is based on Google's shadercam library and extends the shadercam-example app with live streaming support using the GoCoder SDK. The camera preview display is based on Android's camera2 API with real-time filtering using the OpenGL Shading Language (GLSL).

The shadercam-example app was updated to support live streaming by adding a new renderer class (StreamingRenderer) that uses the WZGLBroadcaster API class and WZRenderAPI.VideoFrameRenderer interface from the GoCoder SDK to encode each frame for the video stream while a live broadcast is active.
