I have been using the Streaming plugin from janus snap to connect to a public RTSP stream. Janus Version - latest/stable: v0.11.3 2021-06-23 (1237) 49MB.

Stream URL: rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov

However no matter how many public or in-house RTSP stream I tried I was unable to display them on the browser using janus. However, creating a RTP mounting and using gstreamer as below works:

gst-launch-1.0 rtspsrc protocols=tcp location="{URL}" short-header=TRUE ! rtph264depay ! decodebin ! x264enc tune=zerolatency bitrate=1500 speed-preset=superfast ! rtph264pay ! udpsink host=127.0.0.1 port=8004 sync=false

However, using janus to connect to RTSP apparently works and video is shown and being transferred but janus keeps saying no media is being transmitted and the browser indeed shows 0 kbits/sec...
