<html> <head> <meta http-equiv="content-type" content="text/html; charset=UTF-8"> </head> <body> I am running gstreamer in Ubuntu 19.10 and having troubles getting a pipeline to work. This pipeline : gst-launch-1.0 videotestsrc ! v4l2sink device=/dev/video2 works as expected and sends the videotestsrc to my /dev/video2 device however I want to send a rtsp stream to /dev/video2. I have tried the following which I expected to work but it doesn't work. <style type="text/css"> pre { background: transparent } pre.western { font-family: "Liberation Mono", monospace; font-size: 10pt } pre.cjk { font-family: "Noto Sans Mono CJK SC", monospace; font-size: 10pt } pre.ctl { font-family: "Liberation Mono", monospace; font-size: 10pt } p { margin-bottom: 0.25cm; line-height: 115%; background: transparent } a:link { color: #000080; so-language: zxx; text-decoration: underline }</style> gst-launch-1.0 rtspsrc location=<a class="moz-txt-link-freetext" href="rtsp://170.93.143.139/rtplive/470011e600ef003a004ee33696235daa">rtsp://170.93.143.139/rtplive/470011e600ef003a004ee33696235daa</a> ! decodebin ! videoconvert ! video/x-raw,width=640,height=480,format=RGB ! v4l2sink device=/dev/video2 Output of the command is: Setting pipeline to PAUSED ...

I would really appreciate any pointers. I have tried a bunch of things with no good results.
