That question is partially addressed by the NEWS file (0.9.0, Important notes).

Basically (using vlc command line but the same would apply using libvlc
i guess):
vlc --sub-filter 'marq at foo{marquee=123}:marq at bar{marquee=abc}'

You can the find the specific instances using:
 vlc_object_find_name( p_some_object, "foo", FIND_ANYWHERE );

(Note that an object's name default's to the underlying module's name.)
