</span></div></div><span class="">If I understand you correctly, this is what fails? But what happens

<br>can't work, you can only link a pad once and need to unlink it first
<br>otherwise.
<br><br>From the GStreamer debug logs you should first of all check why rtspsrc
<br>is adding multiple srcpads, it seems like this is already unexpected in
<br>your case. And once that is known we can try to find a solution for
<br>that.
