The correct way to seek is to binary search for the desired position,
and if the seek is relative, choose the next keyframe in the direction
of the seek (i.e. previous keyframe if seek is backwards, next if it's
forwards). I don't know if the timestamps in ogm are reliable enough
for binary search, though; mpeg has this idiocy where they can
jump/reset midstream.
