gstrtpbin current bandwidth and latency

[myles.megyesi]

Hi,

Is there a way to find the bandwidth and latency of a gstrtpbin stream? On the
server side I need to find the outgoing bandwidth and on the client side I
need to find the incoming bandwidth. I also need to find the latency (time
delay) on the client side. Thanks.

I guess you mean the latency added by the jitterbuffer in rtpbin? It's
controlled by a property on rtpbin.

AS for the bandwidth and other stats, you can get them from the "stats"
property of the rtpsource object that you can get from the rtpsession
object with something like:

GObject *rtpsession, *rtpsource;
GstStructure *stats;
g_signal_emit_by_name(rtpbin, "get-internal-session", sessionid,
&rtpsession);
g_signal_emit_by_name(rtpsession, "get-source-by-ssrc, ssrc,
&rtpsource);
g_object_get(rtpsource, "stats", &stats, NULL);

Thanks the bandwidth works great. By latency I actually meant the end-to-end delay from server to client. Is there a way to find that info?

Maybe look for "rb-round-trip" in the stats ?
