Blackmagic cards are an option to capture high definition contents, both camera and laptop sources. Depending on the card installed and the input type you should be able to configure it following these instructions.

Gstreamer plugin installation

Decklink plugin is not installed on your computer by default, so you have to do it manually.

  1. Download the plugin:
    svn checkout http://gforge.unl.edu/svn/gst-decklink
    
  2. Download the Gstreamer development tools
    sudo aptitude install libgstreamer0.10-dev libgstreamer0.10-dev
    # Go to the driver directory and compile
    {code:none}
    ./configure
    make
    sudo make install
    
  3. Make the changes permanent
    sudo cp \-v /usr/local/lib/gstreamer-0.10/libgstdecklink.\* /usr/lib/gstreamer-0.10/
    
  4. Delete the Gstreamer registry and run the gstreamer inspector to force a reload
    sudo rm ~/.gstreamer-0.10/registry.*.bin
    gst-inspect0.10
    

Driver installation

Blackmagic has partial support for Linux. To install their driver you should download the latest one on:
