Comment 17 for bug 1222790

I think the correct test case is to run

gst-launch-1.0 filesrc location=Linux.mp4 ! qtdemux ! vaapidecode ! vaapisink

I used LIBVA_DRIVER_NAME=vdpau to work around bug #964040, because r600_drv_video.so is not provided. The video played about once in five attempts. Other times, I got a black window and an error message.
