Btw, I never seen a webcam that produce 24bit RGB, and the log confirms it's
being color-converted by libv4l2:

  <v4l2src0>[00m   RGB3 (emulated)

Then later S_FMT leads to size 2764800 (match 1280*3*720). But QUERYBUF
returned a size of 0, hence:

  buffer size 0 is smaller then negotiated size 2764800

I'm currently running libv4l2 1.0.0, and this just works. It looks like a
regression in libv4l2, and not in GStreamer.
