First of all this is my first question in the list and i wanna say hi to everyone:) Let's get into my question. I'm writing an application that shows multiple rtsp streams (h264) in part of a gtk window. My problem is i can't detect network failure of streams. Here are the symptoms: Program starts and works perfectly. But when i unplug a network cable of one of the source, program hangs and freezes about 1-1,5 minutes. Then the unplugged source's last frame dropped from the window and program continues to run again. There is no warning or error message in the bus until now. If i plug the cable again, i can get an error message from bus but only in this way. (To be clear, if i plug the cable during freeze, after 15-20 seconds the streams continues, i mean i plug the cable after program responding again.) ******ERR:Could not read from resource. ******ERR:gstrtspsrc.c(3878): gst_rtspsrc_loop_udp (): /GstPipeline:my_pipeline/GstRTSPSrc:Source1: Could not receive message. (Network error: Resolver Error 0 (no error)) ******ERR:Internal data flow error. ******ERR:gstrtspsrc.c(3988): gst_rtspsrc_loop (): /GstPipeline:my_pipeline/GstRTSPSrc:Source1: streaming task paused, reason error (-5) I try to set timeout tcp-timeout retry parameters to "0" of rtspsrc but the freeze time won't decrease. (that's actually another question i can't figure out) Finally i read about reaching rtpbin element inside of the rtspsrc element and connect signals of this internal rtpbin element. I tried it also. I found the rtpbin element by iterating childs and checking gst_object_get_name and connect all signals like on-bye-ssrc on-bye-timeout signal of rtpbin but no callback function called once. Is there anythink that i miss? Your advices? My pipeline is like that: rtspsrc --> rtph264depay --> ffdec_h264 --> ffmpegcolorspace --> videobox --> videorate --> videomixer rtspsrc --> rtph264depay --> ffdec_h264 --> ffmpegcolorspace --> videobox --> videorate --> videomixer rtspsrc --> rtph264depay --> ffdec_h264 --> ffmpegcolorspace --> videobox --> videorate --> videomixer rtspsrc --> rtph264depay --> ffdec_h264 --> ffmpegcolorspace --> videobox --> videorate --> videomixer --> colorspace --> ximagesink My simplified source code is here: <a href="http://pastebin.com/jPrwaN5M" target="_blank">http://pastebin.com/jPrwaN5M</a> Thank you in advance for the replies. -engin <div class="yj6qo ajU"><div id=":146" class="ajR" tabindex="0"> </div></div>
