Disclosure: Everything that follows may be wrong.
I reckon that, except for a few filters, the important metric is PTS,
not
the frame #s assigned at a
filter's input node nor its wall-clock arrival time at a filter's input
node. For example,
'interleave' performs frame interleaves based on the PTSs of incoming
frames -- at least, that's
what I think.
Am I correct?
If so, wouldn't it be helpful if filter documentation included how it
generates PTSs?
PTS are not generated.
ffmpeg -i SOURCE -vf telecine TARGET
What are the PTSs of the first 5 frames at the output of the filter?
Interpolated by very complex formula.
So, the PTSs are generated.
What is the formula? Certainly it can't be anywhere nearly as complex as the differential equations
and boundary conditions that control air flow through a duct of arbitrary shape or the air flow
across an aircraft wing of arbitrary profile. I guess if I can handle those, I'll be able to handle
the generated PTSs of a periodic series of frames, eh?
