Extra space.

NSDictionary has a constructor for having a single key/object pair: dictionaryWithObject:forKey:. I would turn the code a bit differently: #if __MAC_OS_X_VERSION_MIN_REQUIRED >= 1090 unsigned pixelFormat = kCVPixelFormatType_422YpCbCr8; #else unsigned pixelFormat = k32BGRAPixelFormat #endif NSDictionary* attributes = [NSDictionary dictionaryWithObject:Foo forKey:Bar]

Fixed.

NSDictionary has an even simpler notation: NSDictionary* attributes = @{ (NSString*)kCVPixelBufferPixelFormatTypeKey, @ kCVPixelFormatType_422YpCbCr8 } ...which we could safely use in the "#if 1090" block.

VideoToolbox was introduced in Mountain Lion, so this breaks the Lion build.
