QTCarbonCoreImage101

QTCarbonCoreImage101 is a Carbon application demonstrating (using very little code) how to render a QuickTime Movie using Core Image filters and the new video pipeline. It is a good place to start for Carbon developers looking at Core Image, Core Video and Visual Contexts for the very first time. Developers interested in seeing a Cocoa version of this sample should examine QTCoreImage101. In this sample we're using the following framework APIs: Standard QuickTime APIs are used to play back a Movie. AGL APIs are use to create an AGL context for rendering. A QuickTime Visual Context is used as the drawing destination for the QuickTime Movie. Core Image is used to add a filter and render the video frame. Core Video pipeline: Movie -> Visual context -> Core Image Filter -> OpenGL rendering ----> Hardware What is Core Image: Core Image is an extensible architecture built into Mac OS X v10.4 for near real-time, pixel-accurate image processing of graphics as well as video. What is Core Video: Core Video delivers a modern foundation for video services providing a bridge between QuickTime and the GPU for hardware-accelerated video processing. This highly optimized pipeline for video presentation increases performance and reduces CPU load, freeing up resources for other operations.
