The following pipe simply sends audio using udpsink and on another stream on the same pipe receives that audio, i need to use both streams on the same pipeline because of some features on the application I'm developing, but i noticed that when the streams are on the same pipe the pipe simply blocks (but if i build the same test on two different pipelines it works fine), but on older gstreamer versions it works just fine the two streams on the same pipe.

gst-launch -v audiotestsrc ! audioconvert ! audiorate ! "audio/x-raw-int,rate=8000,
channels=1,endianness=1234,width=16,depth=16,signed=true" ! udpsink host=127.0.0.1 port=5000 udpsrc port=5000 caps="audio/x-raw-int,rate=8000,channels=1,endianness=1234,width=16,depth=16,signed=true" ! fakesink

i have tested this pipe on two systems:

Ubuntu 9.04 (Works fine)
gstreamer 0.10.22
gst-plugins-base 0.10.22
gst-plugins-good 0.10.14
gst-plugins-bad 0.10.11
gst-plugins-ugly 0.10.10


Ubuntu 9.10 (Pipe blocks)
gstreamer 0.10.25
gst-plugins-base 0.10.25
gst-plugins-good 0.10.16
gst-plugins-bad 0.10.14
gst-plugins-ugly 0.10.12

A better description can be founded on the mail list, i was completely ignored there so i cant tell if I'm dealing with something stupid or if it is a bug, but since it works on older gstreamer and don't works on new 0.10.25 i supposed it is a bug:

i have made similar tests on source code, that blocks when it is two streams on the same pipe but works fine when it is two separated pipes:

The working test:

The blocking one:
