About what is an internal source?

[liangzhihong1984]

Hi friends.
I have done some operations on a GstRtpbin like this:
    /* get session 0 */
    g_signal_emit_by_name(rtpbin, "get-internal-session", 0, &session);

    /* print all the sources in the session ,this includes the internal source */
    g_object_get(session, "sources", &arr, NULL);

    for (i = 0; i < arr->n_values; i++) {
        GObject *source;

        val = g_value_array_get_nth(arr, i);
        source = (GObject*)g_value_get_object(val);

        printSourceStats(source);
    }

and I have some questions:
1. What is an internal session to this rtpbin? Then what is an external?
2.I was sending only one video stream, but I don't know why I got two sources?
Also like the first question, what is an internal source and what is external?

Can anyone give me some help?


Thank you in advance.


Best Regards,
Leon LIang

Maybe the action signal should just be named "get-session". Anyway, it
gives you the RTPSession with the given ID.

You get the internal source of the session (the SSRC used for sending SR
or RR reports in this session) and a source for each participant in the
session (the SSRCs sending SR or RR to this session).
