If so, wouldn't it be helpful if filter documentation included how it
generates PTSs?
PTS are not generated.
-Something- generates the PTS, although maybe not the filter. OTOH if an
element in the pipeline between decode and encode changes the frame-to-frame
timing, I'd expect that the PTS must be altered (which one could call
"recalculated" or "regenerated").
Some handy references, although I'm sure there are others--
