@abstract CoreVideo specific error codes
@constant kCVReturnSuccess Function executed successfully without errors.
@constant kCVReturnFirst Placeholder to mark the beginning of the range of CVReturn codes.
@constant kCVReturnLast Placeholder to mark the end of the range of CVReturn codes.
@constant kCVReturnInvalidArgument At least one of the arguments passed in is not valid. Either out of range or the wrong type.
@constant kCVReturnAllocationFailed The allocation for a buffer or buffer pool failed. Most likely because of lack of resources.
@constant kCVReturnInvalidDisplay A CVDisplayLink cannot be created for the given DisplayRef.
@constant kCVReturnDisplayLinkAlreadyRunning The CVDisplayLink is already started and running.
@constant kCVReturnDisplayLinkNotRunning The CVDisplayLink has not been started.
@constant kCVReturnDisplayLinkCallbacksNotSet The render and display callbacks or the output callback is not set. You have to set either the render/display pair or the single output callback.
@constant kCVReturnInvalidPixelFormat The requested pixelformat is not supported for the CVBuffer type.
@constant kCVReturnInvalidSize The requested size (most likely too big) is not supported for the CVBuffer type.
@constant kCVReturnInvalidPixelBufferAttributes A CVBuffer cannot be created with the given attributes.
@constant kCVReturnPixelBufferNotOpenGLCompatible The Buffer cannot be used with OpenGL as either its size, pixelformat or attributes are not supported by OpenGL.
@constant kCVReturnPoolAllocationFailed The allocation for the buffer pool failed. Most likely because of lack of resources. Check if your parameters are in range.
@constant kCVReturnInvalidPoolAttributes A CVBufferPool cannot be created with the given attributes.
