Since filters can manipulate the origin of a buffer to, for example, crop image without any memcpy, the buffer origin and dimensions are per-reference properties. Linesize is also useful for image flipping, frame to field filters, etc, and so is also per-reference.

presentation timestamp.
The time unit may change during filtering, as it is specified in the link and the filter code may need to rescale the PTS accordingly.
