Thank you Nicolas.</div><div><br></div><div>However, now I am having a problem that I start the RTSP server, and the pipeline only seems to save when I login with VLC client to view the stream.

To get full control of the recording, I would suggest using an external pipeline, and have a branch that ends with appsink, that will then feed an appsink in the rtspserver pipeline.</div><div><br></div><blockquote type="cite" style="margin:0 0 0 .8ex; border-left:2px #729fcf solid;padding-left:1ex"><div dir="ltr"><div dir="ltr"><div><br></div><div><br></div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Sep 8, 2021 at 1:36 PM Dwight Kulkarni <<a href="mailto:dwight@realtime-7.com">dwight@realtime-7.com</a>> wrote:<br></div><blockquote type="cite" style="margin:0 0 0 .8ex; border-left:2px #729fcf solid;padding-left:1ex"><div dir="ltr"><div dir="ltr">Hi Nicolas,<div><br></div><div>Thank you for this info ! </div><div><br></div><div>In the example shown we get callback to media_configure, and access the pipeline element.
