rtmp-to-webrtc

rtmp-to-webrtc demonstrates how you could re-stream media from a RTMP server to WebRTC. This example was heavily inspired by rtp-to-webrtc

This example re-encodes to VP8. Pion WebRTC supports H264, but browser support is inconsistent. To switch video codecs replace all occurrences of VP8 with H264 in main.go

Instructions

Download rtmp-to-webrtc

export GO111MODULE=on
go install github.com/pion/example-webrtc-applications/v3/rtmp-to-webrtc@latest

Open jsfiddle example page

jsfiddle.net you should see two text-areas and a 'Start Session' button

Run rtmp-to-webrtc with your browsers SessionDescription as stdin

In the jsfiddle the top textarea is your browser's SessionDescription, copy that and:

Linux/macOS

Run echo $BROWSER_SDP | rtmp-to-webrtc

Windows

1. Paste the SessionDescription into a file.
2. Run rtmp-to-webrtc < my_file

Send RTP to listening socket

On startup you will get a message Waiting for RTP Packets, you can use any software to send VP8 packets to port 5004 and Opus packets to port 5006. We have an example using ffmpeg below

ffmpeg

ffmpeg -i '$RTMP_URL' -an -vcodec libvpx -cpu-used 5 -deadline 1 -g 10 -error-resilient 1 -auto-alt-ref 1 -f rtp rtp://127.0.0.1:5004?pkt_size=1200 -vn -c:a libopus -f rtp rtp:/127.0.0.1:5006?pkt_size=1200

Input rtmp-to-webrtc's SessionDescription into your browser

Copy the text that rtmp-to-webrtc just emitted and copy into second text area

Hit 'Start Session' in jsfiddle, enjoy your video!

A video should start playing in your browser above the input boxes.

Congrats, you have used Pion WebRTC! Now start building something cool
