Re: Feeding into QC

Can I feed generated video (probably from a video context) into a
QC comp
for use? I want to feed pre-rendered video from a Core Video
pipeline into a
comp, preferably already in an OpenGL texture.


yes, you can pass CVImageBuffers to a composition image inputs.


Do I use a generator patch, or publish the image inputs of for instance, a
sprite?

the latter - see this sample code:
