doesnt work, we need the filepos based seeking for formats like MPEG-PS/TS
that have timestamp discontinuities and thus no reliable seeking per
timestamp (one of course can seek based on guessing about the discontinuities
but filepos is the well defined alternative if the user dislikes our, to be
implemented guessing)
