<div dir="ltr">Hello,<div><br></div><div>Right now I have a simple pipeline: "videotestsrc ! x264enc ! h264parse ! rtph264 name=pay0". I use the test-launch application, which is an example from the rtps-server plugin. I did some modifications to the application to have both options: transmitting using unicast and multicast.</div><div><br></div><div>I'm using version 1.16.2 of gstreamer, gst-rtps-server and gst-plugins-bad on Ubuntu20.04.</div><div><br></div><div>The simple pipeline works perfectly: I can use ffplay to retrieve the stream (both unicast and multicast). If I modify the pipeline to the following:
"videotestsrc ! x264enc ! h264parse ! rtph264 ! rtponviftimestamp ntp-offset=0 ! name=pay0", I can retrieve the stream using unicast, but when I do it with multicast it does not work. I've used debugging level 4, but I couldn't find anything that said where it went wrong.</div><div><br></div><div>How should I proceed with debugging this?</div><div><br></div><div>Thanks for your help! Kind regards,</div><div>Goran Broeckaert</div><div><br></div><div>PS: I've uploaded the patch to modify the test-launch.c to have the option to use multicast to pastebin: <a href="https://pastebin.com/qjpaYwCL" target="_blank">https://pastebin.com/qjpaYwCL</a> .</div></div>
