+    @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.
