Yowza!
So I was retaining an CIImage * sourceImage on
applicationDidFinishLaunching and set the sourceImage for one
renderer, pass it to another, and also show it in a simple preview
window which was also openGL. Id create my CIImage with emptyImage
My patch, with a render timer at 60fps would output around 20/25 fps.
Now, I have:
- (void) applicationDidFinishLaunching:(NSNotification*)aNotification
{
<snip opengl setup and QC patch loading stuff>
sourceImage = [[QCRenderer QCImage] retain]; // I have no clue if
this is correct, but it seems to work.
}
and within my renderers I simply call ofType: as you suggested, like so:
sourceImage = [v001SourceRenderer valueForOutputKey:@"SourceOutput1"
ofType:@"QCImage"];
My FPS now matches exactly that of QC. If I pump up my preferred
rendering speed, I can get a solid 60FPS, which I cant even get QC to
do.
Changing two lines of code, to change my FPS that drastically is huge.
Thanks!

It will be better to use that opaque type than CVPixelBuffer because
it will be more flexible. If the internal representation one day
turns out to be a CIImage instead, then passing it as a QCImage will
not make a costly conversion.
