Hello guys,

   Right now I try to play video with mfw_v4lsink in i.MX6Q, but when I set negative value to axis-left, it always show "fail to set size,the actual crop settings..." and the axis-left of video window is back to 0. I am wondering if it is a limitation or there are some ways to do that? Thanks very much for your answer in advanced!
