GLX is the "OpenGL Extension to the X Window System" [1]. One of its features
is that you can pass VA-API Surfaces to an OpenGL texture and compose a scene
with it. And this can be done using hardware renderers or software ones, that
depends on your setup.

Though, GLX is on deprecation path (AFAIK) since EGL is the new thing (tm).
