It doesn't matter to you. The way I have seen it is to use it to
put the exact position when a generic index is auto-generated
e.g. with MPEG-ES input.
Seeking then will directly seek to a start of a frame so that
we will not read and try to decode a partial frame.
It's a bit questionable and also broken though (I recently
sent a patch to attempt to fix some issues).
