Compiling gstreamer in general, and gstreamer-vaapi in particular, might a bit
tricky because all the dependencies, either at compilation time and at run
time. You must to keep in mind them while tinkering with them.

What Hyunjun said is a way to simplify a development environment for
gstreamer. You can find more info here:

The problem with version 1.13 is it's a development one. Which means it might
be broken some days or hours, since it's changing constantly.

Instead of creating a symbolic link called gst-master, create it named
gst-1.12 and the script is smart enough to compile the release 1.12
