rtp-forwarder is a simple application that shows how to forward your webcam/microphone via RTP using Pion WebRTC.
go install github.com/pion/webrtc/v4/examples/rtp-forwarder@latest
jsfiddle.net you should see your Webcam, two text-areas and Copy browser SDP to clipboard
, Start Session
buttons
In the jsfiddle the top textarea is your browser's Session Description. Press Copy browser SDP to clipboard
or copy the base64 string manually.
We will use this value in the next step.
Run echo $BROWSER_SDP | rtp-forwarder
- Paste the SessionDescription into a file.
- Run
rtp-forwarder < my_file
Copy the text that rtp-forwarder
just emitted and copy into second text area
You can run any of these commands at anytime. The media is live/stateless, you can switch commands without restarting Pion.
Open rtp-forwarder.sdp
with VLC and enjoy your live video!
Run ffprobe -i rtp-forwarder.sdp -protocol_whitelist file,udp,rtp
to get more details about your streams
Run ffplay -i rtp-forwarder.sdp -protocol_whitelist file,udp,rtp
to play your streams
You can add -fflags nobuffer -flags low_delay -framedrop
to lower the latency. You will have worse playback in networks with jitter. Read about minimizing the delay on Stackoverflow.
