Bug description:
  v4l-info shows that my isight supports UYVY format, but when trying to
  configure it on this format it doesn't produce any data.

  The problem gets worse because this seems to be its preferred format,
  so gstreamer tries to use it and it fails.

  gst-launch autovideosrc ! ffmpegcolorspace ! autovideosink

  Using other formats work.
