title: OpenCV is able to change to composite input?
body: <p>I would like to know if OpenCV is able to set the camera (dev/video1) to composite or S-video input.</p>
  
  <p>The camera I was using only runs in composite input, but v4l2 opens dev/video1 in S-Video input by default.  V4l2 is able to change from S-video to composite input by QT V4l2 utils application. </p>
  
  <p>The opencv is using v4l to capture imagens from camera, and I want to change to composite input in code using OpenCV. Is that possible? If it's not, what is the solution to this?</p>
  
  <p>Thanks in advance.</p>
