Hi Peter,
You'll want to create the pool outside of the display link callback.
You then acquire the opengl buffer from the pool within the callback
where you have written "CVOpenGLBufferPool". After you have passed
the acquired buffer to QC, you then release it (within the callback).
'hope that makes sense.
Cheers,

Is it in the callback you make these changes?
I had this.... And the sample code 'Performer' seems to still do
the same.
static CVReturn _displayLinkCallBack(CVDisplayLinkRef displayLink,
const CVTimeStamp* inNow, const CVTimeStamp* inOutputTime,
CVOptionFlags flagsIn, CVOptionFlags* flagsOut, void*
displayLinkContext)
{
QCApplication* controller =
(QCApplication*)displayLinkContext;
NSAutoreleasePool* pool;
//Create an autorelease pool (necessary to call Obj-C code from
non-Obj-C code)
pool = [NSAutoreleasePool new];
CVOpenGLBufferPool
//Simply ask the application controller to render and display a
new frame
[controller renderAtTime:inOutputTime];
//Destroy the autorelease pool
[pool release];
return kCVReturnSuccess;
}
