## Detailed Description

Events for a stream.

## Field Documentation

## ◆ add_buffer

void(* pw_stream_events::add_buffer) (void *data, uint32_t id)

when a new buffer was created for this stream

## ◆ destroy

void(* pw_stream_events::destroy) (void *data)

## ◆ format_changed

void(* pw_stream_events::format_changed) (void *data, struct spa_pod *format)

when the format changed.

The listener should call pw_stream_finish_format() from within this callback or later to complete the format negotiation and start the buffer negotiation.

## ◆ need_buffer

void(* pw_stream_events::need_buffer) (void *data)

when a buffer is needed (for playback streams)

## ◆ new_buffer

void(* pw_stream_events::new_buffer) (void *data, uint32_t id)

when a buffer can be reused (for playback streams) or is filled (for capture streams

## ◆ remove_buffer

void(* pw_stream_events::remove_buffer) (void *data, uint32_t id)

when a buffer was destroyed for this stream

## ◆ state_changed

void(* pw_stream_events::state_changed) (void *data, enum pw_stream_state old, enum pw_stream_state state, const char *error)

when the stream state changes

## ◆ version

uint32_t pw_stream_events::version
