 ffmpeg can use 'dshow' filters or 'gdigrab' to capture the desktop on
 Windows. However, gdigrab is slow (on Aero-enabled desktops) and dshow
 desktop capture filters aren't shipped with Windows (3rd party filters
 require installation with admin rights).

 in GStreamer, there's a 'dx9screencapsrc' that uses Direct3D 9 and
 performs reasonably well (~18 fps on my computer).

 The source of that module can be found at
