These libs can handle both audio and video, and should have some kind of a Multiplexer to allow you to mix video and audio properly. But if you really want to do this using Opencv, you should be able to use VideoCapture to get the frame rate, have you tried using this? fps = cv.GetCaptureProperty(vc, CV_CAP_PROP_FPS)
