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.
