AW: RELEASE: GStreamer VA-API Plugins 0.6.0

[Bernhard Graaf]

Yes, that was the issue. After installing 0.37 of libva the make runs fine.
But after tiring following pipeline I get the next failure:
gst-launch-1.0 --gst-debug=3 tcpclientsrc host="192.168.1.4" port=12000 ! vaapidecode ! vaapisink

Without using vaapi try this one:

And it works like expected.

What is the reason of: 
gst.vaapi.Display=context, display=(GstVaapiDisplay)NULL;

which version of libva do you have?

It's strange, like if your pkg-config detects a libva>=0.36 but when the code
is linking, a lower version of libva is used.
