A filter can adjust the PTS to a certain extent. This is needed when
the filtering algorithm adds a (computational) delay of a one or a few
samples. But you can't just arbitrarily shift the PTS. That would desync
audio and video.
I don't understand your problem anyway. Normally, the samples are
filtered much more than 15ms ahead of their PTS.
