We don't do calculations with different units (buffer offsets and bytes) anymore but have functions for: 1) getting the number of bytes since the last discont 2) getting the offset (and pts/dts) at the last discont and the previously added function to get the last offset and its distance from the current adapter position. https://bugzilla.gnome.org/show_bug.cgi?id=766647
