Thanks, therefore something like

config_PutPsz( p_vout, "angle", "90" );
var_SetString( p_vout, "video-filter", "rotate" );

will rotate the video by 90 degrees? I deduced this from motion.c
where the transform filter is called instead...
(the code above does not work, but I'd like to know whether I'm
getting any close..)
