[yocto] SATO video player app

[Jim Abernathy]

Now that the Denzil branch supports the CDV 1.0.3 hardware accelerated 
video driver for Cedartrail, I would like to have the Video Player app 
play the mp4 videos accelerated by the hardware. The player currently 
does not accelerate the video.  To play accelerated video, I need to run 
gst from the command line, for example:

gst-launch filesrc location=myvideofile.mp4 ! qtdemux name=demux ! queue 
! vaapidecode ! vaapisink demux. ! queue ! ffdec_aac ! alsasink.

Is there a way to configure the GUI video player to include the right 
pipeline options?
