<div dir="ltr"><div><div><span style="font-family:monospace,monospace">Dear all,<br><br></span></div><span style="font-family:monospace,monospace">I want to expand a beach monitoring system with live streaming.<br>The system is composed of multiple cameras connected to several<br>remote stations located at the roofs of some collaborator hotels.<br>(find samples of the captured images at <a href="http://apps.socib.es/beamon/">http://apps.socib.es/beamon/</a>)<br>The idea is to use gstreamer components to send captured frames<br>as a video steam to a central server able to multicast the stream<br>to multiple clients in a web friendly format (`<video>` tag).<br><br>Hence I would like to ask these two related questions:<br><br> 1. What would be the best media type (codec, container<br> and/or protocol) to transfer the video stream<br> from the remote stations to the central server,<br> in terms of stability and bandwidth consumption?<br></span></div><div><span style="font-family:monospace,monospace"><br></span><div><span style="font-family:monospace,monospace"> Is there any advantage in using RTP (with optional RTCP) over UDP<br></span></div><div><span style="font-family:monospace,monospace"> instead of plain mpeg4, ogg or webm over TCP? <br> <br></span></div></div><div><span style="font-family:monospace,monospace"> 2.
