Summary: pix_video duplicate frames

Initial Comment:
at least on linux (v4l2), people keep reporting that they have problems with duplicate frames.
if the camera runs at a lower rate than the grabber, the same frame might be captured twice. there should be a feedback (e.g. the newimage-flag) to the userspace, if this happens

Message:
unable to reproduce, at least with the new plugin-based code: both v4l and
v4l2 backends should already provide feedback when no new frame could be
grabbed
