How do you play embedded videos in a PDF?

[Splatics]

With some help I have been able to figure out how to extract links from a PDF:

if (CGPDFDictionaryGetDictionary(annotationDictionary, "A", &actionDictionary)) {
        const char* actionType;
        if (CGPDFDictionaryGetName(actionDictionary, "S", &actionType)) {
            if (strcmp(actionType, "GoTo") == 0) {
                CGPDFDictionaryGetArray(actionDictionary, "D", &destArray);
            }
            CGPDFStringRef destName;
            if (CGPDFDictionaryGetString(actionDictionary, "D", &destName)) {
                // Traverse the Dests tree to locate the destination array.
                CGPDFDictionaryRef catalogDictionary = CGPDFDocumentGetCatalog(document);
                CGPDFDictionaryRef namesDictionary = NULL;
                if (CGPDFDictionaryGetDictionary(catalogDictionary, "Names", &namesDictionary)) {
                    CGPDFDictionaryRef destsDictionary = NULL;
                    if (CGPDFDictionaryGetDictionary(namesDictionary, "Dests", &destsDictionary)) {
                        const char *destinationName = (const char *)CGPDFStringGetBytePtr(destName);
                        destArray = [self findDestinationByName: destinationName inDestsTree: destsDictionary];
                    }
                }
            }
            if (strcmp(actionType, "URI") == 0) {
                CGPDFStringRef uriRef = NULL;
                if (CGPDFDictionaryGetString(actionDictionary, "URI", &uriRef)) {
                    const char *uri = (const char *)CGPDFStringGetBytePtr(uriRef);
                    linkTarget = [[NSString alloc] initWithCString: uri encoding: NSASCIIStringEncoding];
                }
            }
        }
    }

My question is now I need to extract embedded videos and handle them in my PDF Viewer. Does anyone know how to do this? I have poured over the official PDF Spec Document. It was a great help in creating the links but seems very confusing when dealing with media. Any help would be great! Thanks!
