Assuming you mean "which source file": none of them. If such a feature
had been implemented, it would be documented in the man page. (If you
aren't talking about source files, then this is a user question, and
should have been posted to the user list - but the answer is still
"sorry, can't do that".)
The basic technique for implementing such a feature - at the cost of
increased CPU (etc.) requirements, meaning much longer waits for the
seek to complete - is known: identify the final keyframe preceding the
desired seek position, seek to that frame, decode frames without
outputting until you reach the desired seek position - but managing that
without either producing garbage video or absolutely destroying A/V sync
is trickier than it sounds.
