I am using opencv to write processed video via cv2.videoWriter function. But that video get write without sound. How can I write a video with its original audio as well.  
I am reading video using cv2.Videocapture(0), and writing it using cv2.videowriter function.  
Tried a lot but unable to to so but unable to do so.

you can’t, using VideoWriter, it only accepts images as input.  
try with ffmpeg / gstreamer instead
