PIPstream is a quick and easy live streaming library. PIP has the same "selector" strcture as jQuery, instead of $, PIP uses $P.

Quick 3 Steps

• $P("document").init();
• $P("#mybutton").cameraTrigger();

Install

npm i pipstream

Usage

1. Initialise WebRTC

import { $P } from "pipstream";

$P("document").init("mychannelname");

Here the channelname parameter can be any unique string used by both the broadcaster and the viewer.

To check the status, we can pass a callback function, to the above function. The first callback is for success, second callback is for failure.

$P("document").init("mychannelname", successCallback, failureCallback);

For example:

$P("document").init("mychannelname", function (response) {
  console.log("success");
});

2. Trigger the Camera

Make a button/link/or any html element to trigger the camera popup. Clicking on the element will trigger the camera permission popup, and get permission from the browser.

HTML

<a href="#" id="startlink">Start</a>

JS

$P("#startlink").cameraTrigger();

3. Show Webcam Video

Creat a html video tag, and make that video element to display local stream video.

HTML

<video width="500" id="myvideo" muted></video>

JS

$P("#myvideo").localVideoStream();

Note: This function accept a success callback method as a parameter.

For example:

$P("#myvideo").localVideoStream(function () {
  $P.getDevices(); // this method is for listing all available video/audio devices in the system.
});

4. Go Live

The above function, 'localVideoStream' get the video/audio stream from the device and play locally. You need to make it go live to broadcast the video.

$P("#myvideo").goLive();

OR

<a href="#live" onclick='$P("#myvideo").goLive()'>Go Live</a>

To End the Stream (Leave Stream)

$P.disconnect();

5. Show Remote Video (Or Watch any live stream)

Create a html video element anywhere and make the video to play the remote stream.

For Example:

<video width="500" id="remotevideo" muted></video>

JS

$P("#remotevideo").remoteVideoStream(function () {
  /* Callback when the stream begins */
});

On Stream End Callback

Use the follwing function to get the callback when the stream ends. (On the receiver side)

$P("#remotevideo").onStreamRemoved(function () {
  /* callback function */
});

$P.getLocalStream().switchDevice("video", deviceID);
// $P.getDevices() can be used to get a list of Device IDs

2. Switch Audio Device
