      Install <application>GStreamer Base Plug-ins</application> by running the

<screen><userinput>mkdir build &amp;&amp;
cd    build &amp;&amp;

meson  setup ..               \

ninja</userinput></screen>

    <para>
      To test the results, issue: <command>ninja test</command>. The tests
      require an X terminal running, or all of the GL tests will fail. Five
      tests may produce timeouts on some systems depending on their graphics
      hardware and speed.

    <note>
      <para>
        When installing, the build process does some additional
        linking.  If you do not have Xorg in /usr, the LIBRARY_PATH
        variable needs to be defined for the root user.  If
        using sudo to assume root, use the -E option to pass
        your current environment variables for the install process.
