Publish, consume, and discover RTMP streams in a network swarm.

$ npm install rtmp-swarm

Start a RTMP network daemon belonging to a network swarm specified by a key.

const discovery = require('./')

const port = process.argv[2] || 0
const key = process.argv[3] || 'rtmp-swarm'

const node = discovery()

node.join(key).listen(port)

node.on('listening', () => {
  const { port } = node.address()
  console.log("onlistening: rtmp://localhost:%s/%s", port, key)
})

node.on('peer', (peer) => {
  console.log('onpeer:', peer);
})

node.on('connection', () => {
  console.log('onconnection');
})

Publish video on demand with ffmpeg to the rtmp endpoint logged above:

$ ffmpeg -re -i 2k.mp4 \
  -c:v libx264 \
  -c:a aac \
  -preset superfast \
  -tune zerolatency \
  -ar 44100 \
  -f flv 'rtmp://localhost:40523/rtmp-stream'

Start another network swarm with the same key, but with a different port and then access the stream with mpv or ffplay:

$ mpv 'rtmp://localhost:42583/rtmp-stream'

where opts is

{
  id: cuid(), // id for this peer
  net: require('net') // network interface
  maxConnections: 0, // max peering connections
}

which are passed directly to discovery-channel.

Returns the server address of this network swarm.

Bind a RTMP server to an optionally specified port and address. Will call cb(err) when listening.

Join a network swarm by key. Will call cb(err) after joining.

Close and destroy the network swarm.

usage: rtmp-stream [-hV] [--help] [--version]
                   [-k|--key|--key=<key>]

options:
  -k, --key=<key>  Discovery key for this RTMP stream.
  -V, --version    Output program version.
  -h, --help       Show this message.

If you do not specify a key, one will be generated for you.
