The buffer reference currently being sent across the link by the source filter.
This is used internally by the filter system to allow automatic copying of buffers which do not have sufficient permissions for the destination. This should not be accessed directly by the filters.

Define the time base used by the PTS of the frames/samples which will pass through this link.
During the configuration stage, each filter is supposed to change only the output timebase, while the timebase of the input link is assumed to be an unchangeable property.
