int(*	propose_buffer_pool )(struct mpipe_sink *self, struct mpipe_dispatch *query)
	Propose a buffer pool to the upstream peer.

Detailed Description

Sink element structure.

Represents a sink element in the media pipeline. Sink elements are terminal elements that consume data from upstream elements through their sink pad.
