Detailed Description

A reference to an AVFilterBuffer.

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.

TODO: add anything necessary for frame reordering

Field Documentation

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.
