Problem using the vaapi config-opts

[Philippe Coatmeur]

I suppose this has to do with this problem 
<https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/commit/64725758eb3ba25f95e4fe9f105e6b8842c54b83> 
but I tried to pull the latest commit, and still, no va :(

HEAD is now at dec3aa55 audioconvert, audioresample, audiofilter: fix 
divide by 0 for input buffer without caps
The Meson build system
Version: 0.63.2
Source dir: /run/build/gstreamer
Build dir: /run/build/gstreamer/_flatpak_build

../meson.build:1:0: ERROR: Unknown options: "va"

This is really frustrating, does anybody know how I can overcome this obstacle?
