Overview
gstreamer-vaapi consists in a collection of VA-API based plugins for
GStreamer and helper libraries.

+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
