I also did not get splitmuxsrc working but that is a different story. The general idea is recording a rtp live stream to disk and split it into files of some size or time. For this part splitmuxsink seems to work well. <code class="bash plain" style="font-family: Consolas, "Bitstream Vera Sans Mono", "Courier New", Courier, monospace; border-radius: 0px; background: 0px center rgb(255, 255, 255); border: 0px; bottom: auto; float: none; height: auto; left: auto; line-height: 20px; margin: 0px; outline: 0px; overflow: visible; padding: 0px; position: static; right: auto; text-align: left; top: auto; vertical-align: baseline; width: auto; box-sizing: content-box; font-weight: 400; font-style: normal; font-size: 14px; min-height: inherit; color: black !important; font-variant-ligatures: normal; font-variant-caps: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: nowrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">gst-launch-1.0 -e rtpbin udpsrc caps=</code><code class="bash string" style="font-family: Consolas, "Bitstream Vera Sans Mono", "Courier New", Courier, monospace; border-radius: 0px; background: 0px center rgb(255, 255, 255); border: 0px; bottom: auto; float: none; height: auto; left: auto; line-height: 20px; margin: 0px; outline: 0px; overflow: visible; padding: 0px; position: static; right: auto; text-align: left; top: auto; vertical-align: baseline; width: auto; box-sizing: content-box; font-weight: 400; font-style: normal; font-size: 14px; min-height: inherit; color: rgb(42, 0, 255) !important; font-variant-ligatures: normal; font-variant-caps: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: nowrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">"application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)H264"</code><span style="color: rgb(51, 51, 51); font-family: Consolas, "Bitstream Vera Sans Mono", "Courier New", Courier, monospace; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; white-space: nowrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; background-color: rgb(255, 255, 255); text-decoration-style: initial; text-decoration-color: initial; display: inline !important; float: none;"> <code class="bash plain" style="font-family: Consolas, "Bitstream Vera Sans Mono", "Courier New", Courier, monospace; border-radius: 0px; background: 0px center rgb(255, 255, 255); border: 0px; bottom: auto; float: none; height: auto; left: auto; line-height: 20px; margin: 0px; outline: 0px; overflow: visible; padding: 0px; position: static; right: auto; text-align: left; top: auto; vertical-align: baseline; width: auto; box-sizing: content-box; font-weight: 400; font-style: normal; font-size: 14px; min-height: inherit; color: black !important; font-variant-ligatures: normal; font-variant-caps: normal; letter-spacing: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: nowrap; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">address=232.0.0.1 port=5000 !

This is where i struggle. My pipeline looks basically like this: gst-launch-1.0 rtpbin name=rtpbin filesrc location=/home/user/video00.mp4 ! qtdemux ! h264parse ! rtph264pay ! capsfilter 'application/x-rtp,ssrc=(uint)1356955624' ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 ! udpsink port=5000 rtpbin.send_rtcp_src_0 ! udpsink port=5001 sync=false async=false udpsrc port=5005 ! rtpbin.recv_rtcp_sink_0 (I was expecting splitmuxsrc to work in the reverse way but it did not somehow and the limitation to the pattern is not exactly what I need anyway.) Then I was trying it with concat what works well but I want to add new files to the playlist dynamically and seek between them. So I was writing some code and trying to dynamically change the pipeline (like in the documentation page with the same name). So first I tried to find a signal or event at the filesrc which tells me when I need to read the next element. I was expecting EOS for example but did not get it there. Then I found out the EOS seems to get created by the demuxer and I tried to probe it there. In the blocking probe I tried to change the location of the filesrc but it complains then. So I tried to change the state to null for the filesrc, change the location and set the state back to playing. Then I got errors about demux.sink was in push mode - which I do not understand. I also got errors telling me I am in the wrong thread for the change. How can it be the wrong thread for me when the example does it in the same way and place? However just to be sure I also tried two different filesrc elements and creating a new one but I end up with the same thing all the time. I also tried a idle callback on the filesrc which did not kick in and a g_idle_add was also not working out for me. What is the correct or best way to achieve this? What is my mistake here?
