You can start with just rtpbin (look at the examples in the rtpbin doc). Or if it's client-server on a local network, maybe you can use RTSP (gst-rtsp-server + rtspsrc), or if you want to go to an internet server, then maybe you want to look at WebRTC, and then use webrtcsink with the appropriate signaler for the server you are using.</div><div><br></div><div>Olivier</div><div><br></div><div>On Wed, 2024-01-03 at 21:48 +0000, Kozikowski, Mark via gstreamer-devel wrote:</div><blockquote type="cite" style="margin:0 0 0 .8ex; border-left:2px #729fcf solid;padding-left:1ex"> <div class="WordSection1"> <p class="MsoNormal" style="margin-bottom:12.0pt"><span style="font-family:"Microsoft Sans Serif",sans-serif;color:blue">Designation:</span><span style="font-family:"Microsoft Sans Serif",sans-serif;color:black">AAC Company Private<br><br></span><span style="font-size:11.0pt"><o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:11.0pt">Thanks, Olivier,<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:11.0pt"><o:p> </o:p></span></p><p class="MsoNormal"><span style="font-size:11.0pt">My criteria right now is low latency, low cpu usage, I’m running on raspberry pi4.<o:p></o:p></span></p><p class="MsoNormal"><span style="font-size:11.0pt">Dropping frames is marginally acceptable.
