janusvrwebrtcsink
The JanusVRWebRTCSink
is a plugin that integrates with the Video Room plugin of the Janus Gateway. It basically streams whatever data you pipe to it (video, audio) into WebRTC using Janus as the signaller.
How to use it
You'll need to have:
- A Janus server endpoint;
- Any WebRTC browser application that uses Janus as the signaller, eg: the
html
folder of janus-gateway repository.
You can pipe the video like this (if you don't happen to run Janus locally, you can set the endpoint
like this: signaller::janus-endpoint=ws://127.0.0.1:8188
):
$ gst-launch-1.0 videotestsrc ! janusvrwebrtcsink signaller::room-id=1234
And for audio (yes you can do both at the same time, you just need to pipe it properly).
$ gst-launch-1.0 audiotestsrc ! janusvrwebrtcsink signaller::room-id=1234
And you can set the display name via signaller::display-name
, eg:
$ gst-launch-1.0 videotestsrc ! janusvrwebrtcsink signaller::room-id=1234 signaller::display-name=ana
You should see the GStreamer videotestsrc
/audiotestsrc
output in your browser now!
If for some reason you can't run Janus locally, you can use their open demo webpage, and point to its WebSocket server:
$ gst-launch-1.0 videotestsrc ! janusvrwebrtcsink signaller::room-id=1234 signaller::janus-endpoint=wss://janus.conf.meetecho.com/ws
By default Janus uses u64
ids to identitify the room, the feed, etc.
But it can be changed to strings using the strings_ids
option in janus.plugin.videoroom.jcfg
.
In such case, janusvrwebrtcsink
has to be created using use-string-ids=true
so its signaller uses the right types for such ids and properties:
$ gst-launch-1.0 videotestsrc ! janusvrwebrtcsink signaller::room-id=1234 use-string-ids=true

Notes
- This plugin supports both the legacy Video Room plugin as well as the
multistream
one; - If you see a warning in the logs related to
rtpgccbwe
, you're probably missing thegst-plugin-rtp
in your system.
