<div dir="ltr">Sounds to me like a bug was fixed between 0.10.30 and 0.10.36. I would look at the summary release notes/changes for each release between the 2. You will probably see this mentioned. </div><div class="gmail_extra"> <div class="gmail_quote">On Fri, Jan 10, 2014 at 7:21 AM, Amir Hassan <<a href="mailto:amir@viel-zu.org" target="_blank">amir@viel-zu.org</a>> wrote: <blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> I have a receiving pipeline that looks like that: gstrtpbin name=rtpbin ximagesrc ! ffmpegcolorspace ! ffenc_mpeg4 trellis=1 flags=0x01000004 me-cmp=2 me-sub-cmp=2 pass=2 bitrate=300000 ! rtpmp4vpay ! rtpbin.send_rtp_sink_0 \ rtpbin.send_rtp_src_0 ! udpsink name=vpsink \ rtpbin.send_rtcp_src_0 ! udpsink name=vcsink \ udpsrc name=vcsrc ! rtpbin.recv_rtcp_sink_0 \ pulsesrc name=psrc ! audioconvert ! opusenc ! rtpopuspay ! capsfilter name=acfilter ! rtpbin.send_rtp_sink_1 \ rtpbin.send_rtp_src_1 ! udpsink name=apsink \ rtpbin.send_rtcp_src_1 ! udpsink name=acsink \ udpsrc name=acsrc ! rtpbin.recv_rtcp_sink_1 i want to wait for GST_MESSAGE_ASYNC_DONE so i can retrieve the caps vom "vpsink". On OpenSuse 13.1 using libgstreamer 0.10.36-10.1.3 it works. On debian using libgstreamer 0.10.30 i never get the message. Any idea what is going wrong or how to work around? greets, amir _______________________________________________ gstreamer-devel mailing list <a href="mailto:gstreamer-devel@lists.freedesktop.org" target="_blank">gstreamer-devel@lists.freedesktop.org</a> <a href="http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel" target="_blank">http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel</a> </blockquote></div> </div>
