I believe a local frame counter you use to generate pts will be good
enough for now. The inlink has the frame rate set, and you can compute the
new frame rate.

Of course, it will not work that good with seeking, but it's what we do in
various other filters already, and there is, AFAIK, no better solution
currently. See the pending decimate filter for details on how to implement
such solution.
