uridecodebin - Query

[Jayanth K.P]

Hi,
   I want to set custom property for the source plugin selected based
on the URI in uridecodebin. For example for
uri="udp://239.0.0.1:2301", uridecodebin will select udpsrc. Now if I
want to set "multicast-iface" property in udpsrc . How can this be
done without modifing the uridecodebin code.

Plz suggest .. Thanks.

Regards,
Jayanth

Once uridecodebin has selected all the elements(probably when you receive the new-decoded-pad signal), you can use the "source" property of the bin to get a handle on the xxxsrc(udpsrc in your case) element and set its properties (multicast-iface, etc).

 

Or you could even handle "autoplug-select" signal.

 

Thanks

Rohit

Connect to the "notify::source" signal, then in the callbck retrieve the
source element via

  GstElement *src;

  g_object_get (uridecodebin, "source", &src, NULL);

  /* set your properties (check for existance of
   * property first if you use different protocols
   * or sources) */
  g_object_set (src, ...., NULL);

  gst_object_unref (src);

Cheers
