I don't know exactly what is going on, though you need to be aware that
to make a comparison between videotestsrc and v4l2src, you should use
is-live=1 on videotestsrc element. A final note that you should test
framerate coming out of your v4l2src, most will do much less then
configured framerate in low light. It would be some other problem of course.
