Re: Live Video into Quartz Composer



I'm working on a project that will incorporate multiple live video streams into a quartz composer scene. The scene works if the video inputs (iSights) are directly connected to the rendering system. The requirements for my project have changed, and the stream is being broadcast as a multicast stream using Quicktime Broadcaster.

I have read (and found) that it isn't possible to use the "Image with Movie" patch to receive this stream (it just displays the quicktime logo with no moving dots), but I was wondering if people thought it would be worth implementing the scene in a QCView and using Quicktime API to receive the stream separately and feed it in as a image input.

I was also hoping people may be able to show me an adaptable Quicktime code sample that I could adapt from, rather than writing some wobbly code from scratch...

You should have a look a http://developer.apple.com/samplecode for some broadcaster receiving sample code.


Once you have the images from the broadcast in memory, simply wrap them in CVPixelBuffers to pass them to Quartz Composer.
