    Revert "recorder: Switch to vp9"
    
    This reverts commit d183f13456991d12ea57ad14ba38a1f7407d0037.
    Switching to the vp9 encoder seemed like a good idea at the time but
    unfortunately it also has the major drawback, that it leaks a serious
    amount of memory every time it is used. See
    https://gitlab.gnome.org/GNOME/gnome-shell/issues/256#note_692743
    for more details.
