Events for a stream.
These events are always called from the mainloop unless explicitly documented otherwise.
uint32_t pw_stream_events::version |
void(* pw_stream_events::destroy) (void *data) |
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
void(* pw_stream_events::control_info) (void *data, uint32_t id, const struct pw_stream_control *control) |
Notify information about a control.
void(* pw_stream_events::io_changed) (void *data, uint32_t id, void *area, uint32_t size) |
when io changed on the stream.
void(* pw_stream_events::param_changed) (void *data, uint32_t id, const struct spa_pod *param) |
when a parameter changed
void(* pw_stream_events::add_buffer) (void *data, struct pw_buffer *buffer) |
when a new buffer was created for this stream
void(* pw_stream_events::remove_buffer) (void *data, struct pw_buffer *buffer) |
when a buffer was destroyed for this stream
void(* pw_stream_events::process) (void *data) |
when a buffer can be queued (for playback streams) or dequeued (for capture streams).
This is normally called from the mainloop but can also be called directly from the realtime data thread if the user is prepared to deal with this.
void(* pw_stream_events::drained) (void *data) |
The stream is drained.
void(* pw_stream_events::command) (void *data, const struct spa_command *command) |
A command notify, Since 0.3.39:1.
void(* pw_stream_events::trigger_done) (void *data) |
a trigger_process completed.
Since version 0.3.40:2. This is normally called from the mainloop but since 1.1.0 it can also be called directly from the realtime data thread if the user is prepared to deal with this.
