      qt4-embedded: Allow use of Qt Media Player in multi-headed system · 0c905f15
      Eric Nelson authored
      Qt-embedded can be used on multiple screens by using environment variables
      QWS_DISPLAY, QWS_MOUSE_PROTO, et cetera.
      
      The gstreamer element mfw_v4lsink used to accelerate media playback on i.MX
      devices can also be pointed at different displays through the 'device'
      property, but the current acceleration patch doesn't have a mechanism for
      setting the property, and always uses the compiled-in default.
      
      This patch allows userspace startup code to override the default through
      the use of the 'v4lsinkdev' environment variable.
      
      Please refer to the Qt4-embedded documentation for proper usage of the
      QWS_x environment variables and the Freescale Multimedia documentation
      for descriptions of the various gstreamer elements.
      
      A sequence of this for a secondary display might be this:
      
      	export QWS_DISPLAY=linuxfb:/dev/fb2:1
      	export v4lsinkdev=/dev/video19
      	my-qt-app -qws
