Waveguide is a revolutionary live streaming facilitation server. Built around WebRTC it helps not only ingest video from many sources, but route that video around to various peers. Waveguide can be configured for a simple setup, or a out-of-the-box video streaming empire.
Waveguide is a very early work in progress.
brew install opusfile fdk-aac
apt install -y pkg-config build-essential libopusfile-dev libfdk-aac-dev libavutil-dev libavcodec-dev libswscale-dev
A simple go build will build Waveguide assuming the above system dependencies are installed.
A sample configuration is provided in config.toml.example, you can copy that file to config.toml to have an out of the box streaming experience.
Using the example config.toml.example you'll get a Waveguide server with RTMP and FTL inputs, hooked into a dummy orchestrator and service. By default the dummy service stream key format is ChannelID-Sha256Hash, so for a ChannelID of 1234 your resulting stream key would be 1234-03ac674216f3e15c761ee1a5e255f067953623c8b388b4459e13f978d7c846f4.
You can export a stream key for testing using:
export RTMP_URL=rtmp://localhost/live/1234-03ac674216f3e15c761ee1a5e255f067953623c8b388b4459e13f978d7c846f4
and then use ffmpeg to produce a RTMP stream:
ffmpeg -re -f lavfi \
-i "testsrc=size=1280x720:rate=60[out0];sine=frequency=1000:sample_rate=48000[out1]" \
-vf "[in]drawtext=fontsize=96: box=1: [email protected]: boxborderw=5: fontcolor=white: x=(w-text_w)/2: y=((h-text_h)/2)+((h-text_h)/-2): text='Hello from FFmpeg', drawtext=fontsize=96: box=1: [email protected]: boxborderw=5: fontcolor=white: x=(w-text_w)/2: y=((h-text_h)/2)+((h-text_h)/2): text='%{gmtime\:%H\\\\\:%M\\\\\:%S} UTC'[out]" \

-bsf:v dump_extra \
-x264-params "nal-hrd=cbr:min-keyint=2:keyint=2:scenecut=0:bframes=0" \
-f flv "$RTMP_URL"
Once ffmpeg is sending bits to Waveguide, you can open your browser to http://localhost:8091/stream/1234 to view your stream. You can replace 1234 with any Channel ID you are testing with.
