You can use capture.c that comes with v4l2 specifications, you will found it
on the wiki. When this is working, you can use for example ekiga or xawtv to
test it with a real application, but to be sure that the read method is
called just desactivate the streaming mode in:
                cap->capabilities = V4L2_CAP_VIDEO_CAPTURE
                                  /* | V4L2_CAP_STREAMING */;
