Hi All.
I am working with QTKit.framework and I want to make my application
works in 64 also.
but I am having some troubles when capturing frames in 64bits arch
(from iSight).
I asked the same question in Quicktime-API list but no luck, so, maybe
here I can get some help ;)
( http://lists.apple.com/archives/quicktime-api/2010/Apr/msg00069.html )
The error:
2010-04-18 03:18:51.608 QTCam[7689:c503] *** QTCaptureSession warning:
Session received the following error while decompressing video: Error
Domain=NSOSStatusErrorDomain Code=-12905 "The operation couldn’t be
completed. (OSStatus error -12905.)". Make sure that the formats of
all video outputs are properly configured.
So, I suppose I have to change kCVPixelFormatType_24RGB from
attributes, but 64RGB didn't not work also.
mCaptureDecompressedOutput = [[QTCaptureDecompressedVideoOutput alloc] init];
[mCaptureDecompressedOutput setPixelBufferAttributes:[NSDictionary
dictionaryWithObjectsAndKeys:
[NSNumber numberWithDouble:320.0], (id)kCVPixelBufferWidthKey,
[NSNumber numberWithDouble:240.0], (id)kCVPixelBufferHeightKey,
[NSNumber numberWithUnsignedInt:kCVPixelFormatType_24RGB],
(id)kCVPixelBufferPixelFormatTypeKey, nil]];
So I am stucked here.
BTW:numberWithUnsignedInt:kCVPixelFormatType_24RGB works in 32 bits.
Thanks in advance.
