Errors running RTP examples
 
|
Hi there,
I'm building a really simple RTP server/client pair, and to do so, I've been trying to get the simple RTP examples from http://cgit.freedesktop.org/gstreamer/gst-plugins-good/tree/tests/examples/rtp to work. For now I focus on the pair of server-alsasrc-PCMA.sh and client-PCMA.sh, because these seem to be the simplest. The problem I run into (with these scripts, but with the more complicated scripts as well) is that they run fine on my Ubuntu 9.10 box, but do not work in Debian unstable. To illustrate this, I have attached two log files, both containing the output of "GST_DEBUG=2 ./server-alsasrc-PCMA.sh" running for a couple of seconds (without actually attaching a client to it). The file good-ubuntu-9.10.log shows that everything works fine running on Ubuntu; using the iptraf program I can see UDP packets as soon as the server starts, and I can connect to the server using the client script. On the other hand, the file bad-debian-unstable.log shows that things go wrong in Debian unstable: the server continuously reports lines like "0:00:00.361053274 7912 0xb6700980 WARN multiudpsink gstmultiudpsink.c:466:gst_multiudpsink_render:<udpsink0> client 0x90d09f8 gave error 101 (Network is unreachable)", and using iptraf I can see that no UDP packets are being sent at all. Apart from these warning lines, the two logs are almost the same. This was tested using streaming to 127.0.0.1 (as is the default in the scripts); I also tried streaming from the one box to the other, and in this case also the server does not work in Debian (the client DOES work here, when receiving an RTP stream from the Ubuntu box). Now since Debian unstable has newer GStreamer libraries than Ubuntu 9.10, the only thing that I can (currently) imagine going wrong is that there is a regression in the libraries somehow.

So any ideas on how to further debug this issue, or alternative ways to get a simple RTP pipeline working, would be very much appreciated.
