You need to fix every file format plugin one by one. Unfortunately, many
formats do not convey a reliable frame rate nor enforce a constant one. So
there is no way that libvlc_media_player_get_fps() can ever be made to work
reliably. Any application that rely on this information is basically broken
by design.
