Will this allow a user to mark a subset of keyframes as random access points ? A user may want seeking to preferably happen to a scene start and not a frame before Will this allow a user to mark a damaged keyframe as such ? A frame might in fact have been a keyframe and maybe the only in the file but maybe was damaged so a parser might fail to detect it.
