All functions related to GStreamer Framework

  in Linux:

      use the dv1394src for DV
      and the v4l2src for Webcams

      it's important to grant permission to device in linux running in terminal:
        sudo chmod 666 raw1394

  in Windows:
      dshowvideosrc is used from the dshowvideowrapper


  To test gstreamer in linux run:
    gst-launch -v -m v4l2src ! decodebin ! ffmpegcolorspace ! autovideosink

  To test gstreamer in windows run:
    gst-launch -v -m dv1394src ! decodebin ! ffmpegcolorspace ! autovideosink

  ( tested with last gstreamer in linux: 0.10.20 )
  ( tested with last gstreamer in windows: 0.10.10 from windows official vinaries and special wrapper dshowvideowrapper )
