Well, I just want to add functions like
libvlc_video_filter_set_brightness()

The already implemented function libvlc_video_set_teletext()
does this:

vout_thread_t *p_vout = GetVout( p_mi, p_e );
vlc_object_t *p_vbi = (vlc_object_t *) vlc_object_find_name( p_vout, "zvbi",
                                                   FIND_ANYWHERE );

I've tested it and p_vbi is NULL aswell :/

So how can I implement a simple libvlc_video_filter_set_brightness() function?
How can one fix the function libvlc_video_set_teletext()?
There should be a way...
