Capturing frames in 64-bits arch

• Ignacio Enriquez Capturing frames in 64-bits arch Apr 26 2010, 19:26
  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.

  Did you try kCVPixelFormatType_48RGB?

  Yes I did. It didn't work.
  I wonder what I am missing. maybe other additional setting?
