Subject: Re: [Freeswitch-dev] VAD, TALK and NOTALK events<br><br>
Please correct me if I’m wrong. <br><br>
<br><br>
The events are indeed fired, but only if the SWITCH_VAD_FLAG_EVENTS_TALK
or NOTALK flags are set for an rtp_session. I found no place
in the code where those flags are set. That is what I meant by
not being “enabled”.<br><br>
<br><br>
I subscribed to the events and received nothing. Then I set the
flags on switch_rtp_enable_vad function, and then I started receiving the
events. Perhaps there is another way of doing it that I’m
missing.<br><br>

The events are fired.<br>
I don't know what you mean by "enabled"<br><br>
You can either bind an event to a callback<br>
in the load function of your custom module.<br><br>
or connect to mod_event_socket on tcp<br>
and request "events talk notalk"<br><br>
void my_event_handler(switch_event_t *event)<br>
{<br><br>
}<br><br>
if (switch_event_bind(modname, SWITCH_EVENT_TALK,
SWITCH_EVENT_SUBCLASS_ANY, my_event_handler, NULL)<br>
!= SWITCH_STATUS_SUCCESS)
{<br>
switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "Couldn't
bind!\n");<br>
return
SWITCH_STATUS_GENERR;<br>
}<br><br>
if (switch_event_bind(modname, SWITCH_EVENT_NOTALK,
SWITCH_EVENT_SUBCLASS_ANY, my_event_handler, NULL)<br>
!= SWITCH_STATUS_SUCCESS)
{<br>
switch_log_printf(SWITCH_CHANNEL_LOG, SWITCH_LOG_ERROR, "Couldn't
bind!\n");<br>
return
SWITCH_STATUS_GENERR;<br>
}<br><br>

Subject: [Freeswitch-dev] VAD, TALK and NOTALK events<br><br>
Hi,<br><br>
>From looking at the code of switch_rtp.c I can see that VAD is
done if<br>
enabled in the sip profile in order to not send packets when there is
no<br>
noise. There are also two events {TALK, NOTALK} which can be fired when
VAD<br>
kicks in, nevertheless these two events are enabled nowhere (or at least
I<br>
didn't find a place in the code where they were enabled), so no matter
if<br>
you ask for them you don't receive them. My questions are the
following:<br><br>
Is there some particular reason for not enabling these two events?
<br>
Is the event queue easily overflowed if these two events are
enabled?<br><br>
Thanks.<br><br>
Cesar Cepeda.<br><br>
