Additional information

In compiling mythtv on gentoo linux using mythtv-33.1-r3.ebuild from the github.com/dr-scream/mythtv-gentoo repository, I get the following error:

In file included from opengl/mythvaapiinterop.h:32,
                 from opengl/mythopenglinterop.cpp:10:
/usr/include/va/va_glx.h:10:25: fatal error: x86_64-pc-linux-gnu/va/va_glx.h: No such file or directory

      |                         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I have installed the only (and latest) version of libva available in the current gentoo repository and:

it appears that libva-2.22 no longer includes va_glx.h
