RosyWriter

This sample demonstrates how to use AVCaptureVideoDataOutput to bring frames from the camera into various processing pipelines, including CPU-based, OpenGL (i.e. on the GPU), CoreImage, and OpenCV. It also demonstrates best practices for writing the processed output of these pipelines to a movie file using AVAssetWriter.

The project includes a different target for each of the different processing pipelines.
