how to add data to a frame

I get image from camera: CvCapture* input = cvCaptureFromCAM(0); CvVideoWriter writer = createVideoStream( "film.avi"; ...); IplImage colourImage = cvQueryFrame(input); // Here, I will add data (for exemple text) associated to the image cvWriteFrame( writer, colourImage );

Is there a way to add information into the AVI file linked to the frame

Best regards
