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
