Detailed Description

Base source element structure.

The source element is responsible for generating data and pushing it downstream. It contains a source pad for output.

Field Documentation

◆ decide_buffer_pool

int(* mpipe_src::decide_buffer_pool) (struct mpipe_src *self, struct mpipe_dispatch *query)

Decide the buffer pool for the downstream peer.

A demand reaches a proposed pool only through mpipe_buffer_pool_set_config; an element deciding for its own pool rebuilds its config baseline here on every negotiation.

◆ element

struct mpipe_element mpipe_src::element

Base element structure.

◆ num_buffers

uint32_t mpipe_src::num_buffers

Number of buffers that the source outputs before sending EOS; 0 means will run forever.

◆ pool

struct mpipe_buffer_pool* mpipe_src::pool

Buffer pool for managing output buffers.

◆ set_caps

int(* mpipe_src::set_caps) (struct mpipe_src *self, const struct mpipe_structure *caps)

Apply the negotiated capability to the source pad.

◆ src_pad

struct mpipe_pad mpipe_src::src_pad

Source pad for output data.
