I am attempting to grab the frames out of a QTMovie. The grabbing part
works, but the loop that I have breaks around the last iteration
with EXC
BAD ACCESS.
Here is the code:
while (QTTimeCompare([myMovie currentTime], [myMovie duration]) !=
NSOrderedSame)
{
// I do some stuff with some things
// Which seems to work fine
[myMovie stepForward];
}
I believe that -duration is returning the time the movie would have
when
it finished, whereas when I reach the last frame -currentTime returns
something like -duration - the_time_a_frame_would_last so my call to
QTTimeCompare never returns true and I loop past the last frame.
My intuition is to look for a way to determine the number of frames
in a
QTMovie and the frame that it is currently on, but if there is a
better
way to solve the problem, I would love to hear.
