receiving pipeline with changing sources

[Johannes Bauer]

Hello dear devs!

First of all I want to thank you for your work. Gstreamer is awesome and very handy streaming tool.

I am trying to build a pipeline for a mpa encoded rtp multicast stream.
The goal is to stream from a server to many raspberrys. On the server i run gst 1.8.1, on the pi 1.2.0.

I would like to change the sending sources while the receiving stream is running.
First I stream the mic input, which works fine.
But then i want to stream an mp3 file ant then i get no output. I need to restart the receiving pipeline in order to get a sound output for the second stream.

It does not matter if I stream mic or mp3 first.

streaming mic pipe:

gst-launch-1.0.exe rtpbin name=rtpbin autoaudiosrc
! audioconvert ! lamemp3enc ! rtpmpapay ! application/x-rtp,clock-rate=(int)9000
0,payload=(int)14 ! rtpbin.send_rtp_sink_1 rtpbin.send_rtp_src_1 ! udpsink host=
239.192.55.1 port=4000

streaming file pipe:

gst-launch-1.0.exe rtpbin name=rtpbin filesrc locat
ion=C:\\test.mp3 ! mpegaudioparse ! rtpmpapay ! application/x-rtp,clock-rate=(in
t)90000,payload=(int)14 ! rtpbin.send_rtp_sink_1 rtpbin.send_rtp_src_1 ! udpsink
 host=239.192.55.1 port=4000

receiving pipe:

gst-launch-1.0.exe rtpbin name=rtpbin udpsrc multic
ast-group=239.192.55.1 auto-multicast=true port=4000 caps=application/x-rtp,cloc
k-rate=(int)90000,encoding-name=(string)MPA,media=(string)audio,payload=14 ! rtp
bin.recv_rtp_sink_0 rtpbin. ! rtpmpadepay ! mpegaudioparse ! mad ! audioconvert
! autoaudiosink

here is the output of the receiving pipeline:

I also tried making the receiving side with py-gst. First stream plays fine. And the second stream plays very distorted and following message is displayed:

GStreamer-CRITICAL **: gst_util_uint64_scale_int: assertion `denom > 0' failed 

If i stream the first stream again it plays fine as well. I think there may be a problem with the clock jumping.

Do you know a way to make this work?

Kind regards
