So far, we have used VLC, Cheese, or a simple OpenCV based application to test the V4L2 device on our ARM platform, and I have no idea which capture method those are using. Is there a very simple V4L test application that we could use to hack the buffer unmap/remap trick you're suggesting as a test ?
