Not yet merged, but here is more info. These new properties reflect
MLT's "cooked" values that represent the detected media properties by
taking into consideration heuristics between the muxer and codec
values, selected stream indexes, and overrides (e.g. force_fps):


However, they are not guaranteed to be set and final until you at
least get_frame(), get_image(), and get_frame() one more time. This is
what melt will do to generate an automatic profile when none is
