</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I add a watch to the bus of a device monitor:
<br>
<br>
<br>
gboolean message_func(GstBus *bus, GstMessage *message, gpointer user_data) {<br>
GstDevice *device = NULL;<br>
gchar *name = NULL;<br>
<br>
switch (GST_MESSAGE_TYPE (message)) {<br>
case GST_MESSAGE_DEVICE_ADDED:<br>
[...]<br>
break;<br>
case GST_MESSAGE_DEVICE_REMOVED:<br>
[...]<br>
break;<br>
default:<br>
break;<br>
}<br>
return G_SOURCE_CONTINUE;<br>
}<br>
<br>
GstDeviceMonitor *monitor = gst_device_monitor_new();<br>
GstBus *bus = gst_device_monitor_get_bus(monitor);<br>
gst_bus_add_watch(bus, message_func, NULL);<br>
gst_object_unref(bus);<o:p></o:p></p>
</div>
<p class="MsoNormal">But it is not working for me. I add a new video device, but it never enters message_func.<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Any idea why is this happening?<o:p></o:p></p>
