Unless I'm very much mistaken, there is no such feature.

It would indeed be very nice, since it would allow seeking to any frame
for *any* purpose (not just for transcoding).

Unfortunately, although the basic technique is fairly simple, it does
not appear remotely easy to implement. (I suggested it years ago, and
tried it myself once; I know something whereof I speak...)
