<h2>Description</h2>
<p>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.</p><p>Developers interested in seeing a Cocoa version of this sample should examine QTCoreImage101.</p><p>In this sample we're using the following framework APIs:</p><p>Standard QuickTime APIs are used to play back a Movie.</p><p>AGL APIs are use to create an AGL context for rendering.</p><p>A QuickTime Visual Context is used as the drawing destination for the QuickTime Movie.</p><p>Core Image is used to add a filter and render the video frame.</p><p>Core Video pipeline:</p><p>Movie -> Visual context -> Core Image Filter -> OpenGL rendering ----> Hardware</p><p>What is Core Image:</p><p>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.</p><p>What is Core Video:</p><p>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.</p>
