C++ (Cpp) pa_mainloop_poll Examples

Example #1

File: pulse-input.c Project: Jhonthe7th/obs-studio

/*
 * Iterate the mainloop
 *
 * The custom implementation gives better performance than the function
 * provided by pulse audio, maybe due to the timeout set in prepare ?
 */
static void pulse_iterate(struct pulse_data *data)
{
	if (pa_mainloop_prepare(data->mainloop, 1000) < 0) {
		blog(LOG_ERROR, "Unable to prepare main loop");
		return;
	}
	if (pa_mainloop_poll(data->mainloop) < 0) {
		blog(LOG_ERROR, "Unable to poll main loop");
		return;
	}
	if (pa_mainloop_dispatch(data->mainloop) < 0)
		blog(LOG_ERROR, "Unable to dispatch main loop");
}

Example #2

File: conn.c Project: marcandrysco/AudioManipProg

static void *conn_thread(void *arg)
{
	struct pulse_conn_t *conn = arg;

	while(true) {
		pa_mainloop_prepare(conn->loop, -1);
		pa_mainloop_poll(conn->loop);

		if(conn->quit)
			break;

		pa_mainloop_dispatch(conn->loop);
	}

	return NULL;
}

Example #3

File: apulse-mainloop.c Project: Alpherie/apulse

APULSE_EXPORT
