Bug Description

In the current Karmic package of gst-plugins-base0.10, gstreamer-based voip apps such as Empathy have a *very* large latency in sending. If I call a SIP echo test and say something, it takes about 13 seconds before I hear my voice echoed back to me.

This is a known bug in gstreamer, fixed by the patch http://cgit.freedesktop.org/gstreamer/gst-plugins-base/commit/?id=058776bcf1ab218b509d19685a0b528d71c65f98 .

Applying this patch to version 0.10.24-1 of the gst-plugins-base0.10 source package and rebuilding makes everything work as expected.

stderr from Empathy

Description of problem:
Frist I tried to make a call with Pidgin (XMPP/Jingle) and in one case (with upstream developer ;-)) I have managed to have a call. Except that my voice was approx. 15 sec delayed on the other side of the communication.

Same happened to me now when using Empathy with SIP.

Version-Release number of selected component (if applicable):
empathy-2.27.91.1-6.fc12.x86_64
telepathy-sofiasip-0.5.17-1.fc12.x86_64
gstreamer-plugins-good-0.10.16-1.fc12.x86_64
pidgin-2.6.1-1.0.mc.1.fc12.x86_64

How reproducible:
100%

Steps to Reproduce:
1.just use VoIP application using GStreamer
2.
3.

Actual results:
my voice is delayed for approx. 15 sec

Expected results:
delay in reasonable amount (less than few sec, I guess)

Yes, quality of the call is still unusable, but that's not GStreamer (or PA) fault. This has been fixed.
