Hi,
I am using QTKit 7 API for processing my movies.
My attempt is to create a new movie from an existing one.
I accomplish this by stepping through each frame image of the source movie,
processing that image and then adding these images to the destination movie
specifying the codec and quality.
The sample codlet follows,
QTMovie* theMovie = [ [ QTMovie alloc ] initWithFile:@"Cinepak.avi"
error:nil ];
NSImage* newImage = nil;
QTTime endTime = [ theMovie duration ];
while( NSOrderedSame != QTTimeCompare([ theMovie currentTime ],endTime) )
{
newImage = [ theMovie currentFrameImage ];
[ newImage lockFocus ];
[ newImage unlockFocus ];
}
[ theMovie release ];
While taking the current frame image and processing it, the application
consumes a lot of memory. Do we need anymore steps or implement any delegate
method so as to avoid this problem?
Any positive response is appreciated.
Thanks in Advance,
Muhammad Ali TK
