the feature would be useful for different purposes, especially for
normalization/correction timestamp filters (e.g. setpts).
1. I could export pkt_duration in AVFrame, like it is done with
pkt_pts, duration is expressed in stream time_base units.
This alone is not sufficient, because to decode pkt* things we need
to reference the AVStream, which is not always available.
2. I create a duration field in AVFrame, with no specified timebase,
which is done for passing the duration information between
different layers (e.g. lavc -> lavfi -> lavc), similar to what we
did for pts.
Then I could add a time_base unit in AVFrame, which is used for
specifying the PTS and duration timebase.
3. a combination of 1/2
Comments are welcome.
