1.)QTMovie mMovie and Movie qtMovie are instance variables in my
controller. I create an empty Quicktime movie on the main thread,
assigned to the qtMovie instance variable.
2.)I then create a QTMovie from the empty Quicktime movie using:
mMovie = [QTMovie movieWithQuickTimeMovie:qtMovie disposeWhenDone:YES
error:nil];
3.)[mMovie retain];
4.)DetachMovieFromCurrentThread(qtMovie);
5.)I detach a worker thread using detachNewThreadSelector:
6.)In the worker thread method:
EnterMoviesOnThread(0);
AttachMovieToCurrentThread(qtMovie);
7.)Attempt to use [mMovie addImage: forDuration: withAttributes: ];
Yet Step 7 causes a signal 11 crash. I am sure that the image data
is valid.
Any ideas? Only thing I can point out is that there are 2
autorelease pools...I create one at the beginning of the worker
thread method. Within this method I create another autorelease pool
before calling another method which renders the image and performs
the [mMovie addImage:]. I release the second pool after this render
method returns. This render method is called repeatedly in a loop to
render frames and add each one to a movie. The second pool is
necessary because there are objects generated in the render method
which accumulate if I do not release the entire pool.
Any ideas? This is driving me nuts.
Cheers,
Juan
