PiStreamer 🎥

PiStreamer is a nodeJS module that allows streaming the raspberry pi camera module output over websocket to a webpage using a modified version of 131/h264-live-player.

  

Origin

PiStreamer has been created due to a need of a streaming module for my end-of-studies work. When looking for a suitable one that could fulfill my expectations, I've found the amazing 131's repository. I reworked and simplified the server side in Typescript ~~and modded the client decoder~~ (not anymore!!) according to my needs.

Installation

``
npm i pistreamer
`

Example

To run an example of the project, enter the following commands:
`
git clone https://github.com/TeaFlex/PiStreamer.git
cd PiStreamer
npm i
npm run test
`

Usage

Server configuration:
`js
const http = require('http');
const {createClient, createServer} = require('pistreamer');
const port = 8000;
/*
Create a server with an instance of PiStreamerServer with
the given options. Here, it will stream a 244x352 video at 15 fps,
the stream will end if there's no viewers left and there's a limit of 5 viewers.
*/
const piStreamer = createServer(http,{
videoOptions: {
fps: 15,
height: 244,
width: 352
},
dynamic: true,
limit: 5
});

//Put some routing here

piStreamer.listen(port, () => {
//create a http-live-player.js file in your static folder.
createClient('./some-static-folder');
console.log(App running and listening to port ${port});
});
`

Client configuration:
`html



`

`js
var canvas = document.createElement("canvas");
//Pass a canvas to de decoder.
var player = new WSAvcPlayer(canvas, "webgl", 1, 35);
//Connect to your server.
player.connect('ws://your-ip-or-domain-name');
window.player = player;

//Call any function of the player.
document.getElementById('startStream').addEventListener('click', () => {
player.playStream();
document.body.appendChild(canvas);
});
document.getElementById('stopStream').addEventListener('click', () => {
player.stopStream();
document.body.removeChild(canvas);
});
document.getElementById('disconnect').addEventListener('click', () => {
player.disconnet();
document.body.removeChild(canvas);
});
`

If you want to send personnalized messages, you can also do like this:

`js
var canvas = document.createElement("canvas");
var player = new WSAvcPlayer(canvas, "webgl", 1, 35);
player.connect('ws://your-ip-or-domain-name');
//We take the ws client from the player;
var wsClient = player.ws;
window.player = player;

document.getElementById('myaction').addEventListener('click', () => {
wsClient.send("my personnalized action");
});

//Do stuff with player methods
``
