Hi. I am developing an application using pygst and tcpserversrc with tcpclientsink. Aside some unnecessary stuff for that matter, my program is as the one in this tutorial [<a href="http://www.jejik.com/articles/2007/01/streaming_audio_over_tcp_with_python-gstreamer/" target="_blank">http://www.jejik.com/articles/2007/01/streaming_audio_over_tcp_with_python-gstreamer/</a> ], adding a bus_watch on each side (server and client) that listens for an EOS message. I am aware that network streaming is used principally for live stream, but in this case I want to be able to detect when a stream sent to the server has ended. Tcpserversrc does not provide an EOS message after is not receiving data, and I don't know if that is the functionality or is a bug. In the debug file I can see that when the audio in the server, which goes through an alsasink, has stopped playing, I get the following message: basesrc gstbasesrc.c:2056:gst_base_<div id=":20o" class="ArwC7c ckChnd">src_loop:<tcpserversrc0> pausing after gst_base_src_get_range() = wrong-state but I am unable to find the reason for that error. The pipeline doesn't go to NULL state neither. Using gstreamer 0.10.18 with pygst 0.10.11 The same message can be obtained using the command lines at the server and client sides, respectively gst-launch-0.10 tcpserversrc host=localhost port=8080 ! decodebin ! audioconvert ! alsasink gst-launch-0.10 filesrc location=/home/test.mp3 ! tcpclientsink host=localhost port=8080 The full debug file for the server is here [<a href="http://pastie.org/349940" target="_blank">http://pastie.org/349940</a>], with the mentioned line highlighted. Thanks in Advance Ruben M</div>
