Hmm, maybe you should try to build all gstreamer projects and use it without
installation.
There's a simple way provided by gstreamer.
Note that this is going to pull out the master of gstreamer.

Here's the step:
1. Pull and build all gstreamer projects
  1) Download the script
https://cgit.freedesktop.org/gstreamer/gstreamer/plain/scripts/create-uninstalled-setup.sh

  2) Modify the script to add gstreamer-vaapi 
  In line 46:
  from MODULES="gstreamer gst-plugins-base gst-plugins-good gst-plugins-ugly
gst-plugins-bad gst-libav"
  to  MODULES="gstreamer gst-plugins-base gst-plugins-good gst-plugins-ugly
gst-plugins-bad gst-libav gstreamer-vaapi"

  3) Run the script
   # sh ./create-uninstalled-setup.sh ( which creates ~/gst directory by
default )

  4) Get into the gst-uninstalled shell and build all
   # ~/gst/gst-master ( by default )
   # cd <MODULE>; ./autogen.sh; make
   ( First gstreamer, then gst-plugins-base, then the other modules.
     You do NOT need to do 'make install' )

2. Test
 Once step 1 is all done, you should verify if it's built perfectly on
gst-uninstalled shell.
 # gst-inspect-1.0 --version : this should print out "1.13"
 # gst-inspect-1.0 vaapi : this should print out information of vaapi
elements.
 # gst-launch-1.0 playbin [file] : should play well. (check if vaapi
elements are working with GST_DEUBG=vaapi*:6)

This is not going to harm your system since they are not installed to your
/usr/local/lib or /usr/lib.
You can just run ~/gst/gst-master to get into the sandboxed shell and then
you can use your new gstreamer.
