Right, this is a technical limitation of most (if not all) video
encodings, the problem is, P and actually even B frames can only show
relative information from the PREVIOUS I frame, implementing such a
thing would required buffering the decoded frames from the previous I
frame up to the current frame and stepping back through them, as you can
guess this isn't a default feature in decoding libraries.

So, for the short answer, no, this is not possible, nor likely to be
possible in the near future.
