Usage
-----
VA elements are automatically plugged into GStreamer pipelines. So,
using playbin2 should work as is. However, here are a few alternate
pipelines constructed manually.
* Play an H.264 video with an MP4 container in fullscreen mode
$ gst-launch-0.10 -v filesrc location=/path/to/video.mp4 ! \
qtdemux ! vaapidecode ! vaapisink fullscreen=true
* Play a raw MPEG-2 interlaced stream
$ gst-launch-0.10 -v filesrc location=/path/to/mpeg2.bits ! \
mpegvideoparse ! vaapidecode ! vaapipostproc ! vaapisink
