I tried to write a program to use two channels from the card by following the example program of V4l2. However, I met a very strange problem. When I kept capturing image, there were several lines following the moving objects like a ghost (sometimes more than one ghost) on the collected image. I can not figure out what causes this problem and how to fix it. The standard xawtv does not have this problem when only one channel is displayed. Any comments will be helpful and many thanks in advance.
