play video within video

Here is my code which overlays an image ( replace1.jpg) on live camera feed. how can I play a video ( say .avi ) file in the specified area ? or what if I would like to play a sound ?

Mat repImage = imread("replace1.jpg"); vector<point2f> imagePoints = { Point2f(0, 0), Point2f(repImage.cols, 0), Point2f(repImage.cols, repImage.rows), Point2f(0, repImage.rows), };

                Mat transmix = getPerspectiveTransform(imagePoints, newLEDPoints);
                warpPerspective(repImage, cameraFeed, transmix, cameraFeed.size(), cv::INTER_LINEAR, cv::BORDER_TRANSPARENT);

  play video within video
 Here is my code which overlays an image ( replace1.jpg) on live camera feed. how can I play a video ( say .avi ) file in the specified area ? or what if I would like to play a sound ?
        Mat repImage = imread("replace1.jpg");
                vector<Point2f> imagePoints = { Point2f(0, 0), Point2f(repImage.cols, 0),                     Point2f(repImage.cols, repImage.rows), Point2f(0, repImage.rows), };

                Mat transmix = getPerspectiveTransform(imagePoints, newLEDPoints);
                warpPerspective(repImage, cameraFeed, transmix, cameraFeed.size(), cv::INTER_LINEAR, cv::BORDER_TRANSPARENT);
  If I would like to play replace1.avi instead of displaying replace1.jpg how can it be possible?
