I am developing a Nvidia deepstream inference application with multiple RTSP sources.<br>
Where each individual source is constructed using uridecodebin plugin. Until this point, I have developed a pipeline with multiple source bins are connected to typical inference pipeline as per our use case something like this.</p>

source-bin-1 --|—[Inference pipeline as per Nvidia Deepstream Inference plugins]<br>

Which is working totally fine!</p>

I am looking to incorporate RTSP reconnection in case any of the RTSP sources (camera) is down for a while and comes up after some time.</p>

In case of source error, I am setting a particular uridecodebin state to NULL and then to PLAY again.</p>
<p style="color:rgb(51, 51, 51);font-family:DIN-Web-Pro, Helvetica, Arial, sans-serif;font-size:15px;letter-spacing:0.15px;background-color:rgb(255, 255, 255)">
My observations after performing some test cases are:</p>
<ol style="margin:1em 0px 1em 1.25em;padding:0px 0px 0px 1.25em;clear:both;color:rgb(51, 51, 51);font-family:DIN-Web-Pro, Helvetica, Arial, sans-serif;font-size:15px;letter-spacing:0.15px;background-color:rgb(255, 255, 255)">
<li>When I am using [rtspsrc-decodebin] as the source-bin my reconnection logic of setting the state to NULL and PLAY works fine and I am able to reconnect to my RTSP source successfully. Here when I set the source-bin state to PLAY it returns me GST_STATE_CHANGE_ASYNC
and the source-bin is able to provide frames to the upstream elements.</li><li>But In the case of [uridecodebin] as the source-bin, my same reconnection logic does not work. Here the observation is after I set the source-bin state to PLAY it returns me GST_STATE_CHANGE_NO_PREROLL and my overall pipeline gets stuck. It is not giving
me the further error of source disconnected but also not able to provide frames to the upstream elements.</li></ol>

The main difference I can conclude here is that when I am using uridecodebin and changing state to PLAY it is returning with GST_STATE_CHANGE_NO_PREROLL and I am not able to reconnect, while with rtspsrc it is returning GST_STATE_CHANGE_ASYNC and I am able
to connect.</p>

I am seeking help to successfully reconnect to my RTSP source when I am using uridecodebin as the source-bin.</p>

Thank you in advance!!</p>
