Be careful when accessing the QCRenderer from several threads at once
But is it ok having multiple CVDisplayLinks, one for each
QCRenderer (say there being a max of 5 QCRenderers on screen at
once?). As in, is there a global state shared between QCRenderers
that might need some lovin?
it's fine to have multiple QCRenderers on different threads,
however, your should minimize the number of CVDisplayLinks
Ah, I see. So I can just use on CVDisplayLink for every renderer. I'd
hope that'd be fast. But I'd have to somehow determine if the
renderer is even on the screen. Well, I guess if QT can do it with
the same amount of movies.
Since this is my very first time ever using Quartz Composer, since
I've already rewrote the Quartz Composer display code twice (once
in HIMovieView, once in QCView when HIMovieView kept locking the
application randomly)
obviously this should not happen: if you have a reproducible, please
make sure you fill a bug report at http://bugreport.apple.com
It's reproducible, but time consuming. It could take hours before it
is reproduced. And there's two other bugs in HIMovieView that make it
unsuitable (<radr://4556530> and the cause of
<http://developer.apple.com/qa/qa2005/qa1417.html>,
<radr://3882439>). Also the fact HIMovieView has to be given a time
for the length of the Quartz Composer document isn't too fun.
Basically, I've given up on HIMovieView at this point.
I'm wondering if there are any downsides other than the amount of
initial setup work done when using QCRenderer.
there should be no downside, it's pretty using the QC engine directly
Excellent, than I shall explore this option.
