embedding HTML5-RTSP player for IP cams

Embedding an RTSP player in a web page

A browser cannot play RTSP streams directly, therefore it is necessary to convert the RTSP stream into HTML5 on the WCS server’s side

Use these instructions for quick installation and configuration of the server. In addition to that, you can connect to our demo server demo.flashphoner.com via the Websockets protocol to perform the tests.

Step-by-step instructions for an RTSP HTML5 player embedding

To embed an RTSP player in our web page, let’s create two empty files: player-min.html and player-min.js. These files will contain the minimal code for our player’s operation.

Let’s study the contents of the files

HTML

Place the necessary elements in player.html:

1. Import the script of the main API

<script type="text/javascript" src="https://flashphoner.com/downloads/builds/flashphoner_client/wcs_api-2.0/current/flashphoner.js"></script>

2. Import the script of the player

<script type="text/javascript" src="player-min.js"></script>   

3. Initialize the API on page load

<body onload="init_api()">

4. Add the div element that the video for the player will be added to

<div id="myVideo" style="width:320px;height:240px;border: solid 1px"></div>

5. Add the Play button, the clicking on which will initialize connection to the server and start playing the video

<input type="button" onclick="connect()" value="PLAY"/>

The full code of the HTML page looks as follows:

<!DOCTYPE html>
<html lang="en">
<head>   
    <script type="text/javascript" src="https://flashphoner.com/downloads/builds/flashphoner_client/wcs_api-2.0/current/flashphoner.js"></script>
    <script type="text/javascript" src="player-min.js"></script>   
</head>

<body onload="init_api()">
<div id="myVideo" style="width:320px;height:240px;border: solid 1px"></div>
<br/><input type="button" onclick="connect()" value="PLAY"/>
</body>
</html> 

JavaScript

1. Create the constants for the player operation status

var SESSION_STATUS = Flashphoner.constants.SESSION_STATUS;
var STREAM_STATUS = Flashphoner.constants.STREAM_STATUS;

2. Create the variable for the Websocket session

var session;

3. Initialize API when the HTML page is loaded

function init_api() {
    console.log("init api");
        Flashphoner.init({
        });
}

4. Connect to the WCS server via Websocket. In this example, we are using our demo server. To test your own server, replace “wss://demo.flashphoner.com” with your WCS address

function connect() {
    session = Flashphoner.createSession({urlServer: "wss://demo.flashphoner.com"}).on(SESSION_STATUS.ESTABLISHED, function(session){       
        console.log("connection established");
        playStream(session);
    });
}

5. Then, create a session.createStream() stream and transmit the RTSP URL “rtsp://myrtspserver/stream1” and the element of myVideo as the parameters. Done, the video stream is played on the web page.

For everything to work correctly, replace “rtsp://myrtspserver/stream1” with the address of the required RTSP stream

function playStream() {
    var options = {name:"rtsp://myrtspserver/stream1",display:document.getElementById("myVideo")};    
    var stream = session.createStream(options).on(STREAM_STATUS.PLAYING, function(stream) {
        console.log("playing");
    });
    stream.play();
}

The full JavaScript code looks as follows:

//Status constants
var SESSION_STATUS = Flashphoner.constants.SESSION_STATUS;
var STREAM_STATUS = Flashphoner.constants.STREAM_STATUS;

//Websocket session 
var session;


//Init Flashphoner API on page load
function init_api() {
    console.log("init api");
        Flashphoner.init({
        });
}

//Connect to WCS server over websockets
function connect() {
    session = Flashphoner.createSession({urlServer: "wss://demo.flashphoner.com"}).on(SESSION_STATUS.ESTABLISHED, function(session){       
        console.log("connection established");
        playStream(session);
    });
}

//Playing stream with given name and mount the stream into myVideo div element
function playStream() {
    var options = {name:"stream1",display:document.getElementById("myVideo")};    
    var stream = session.createStream(options).on(STREAM_STATUS.PLAYING, function(stream) {
        console.log("playing");
    });
    stream.play();
}

As a result, we get a minimal player that is basically a div block with a frame and is able to request an RTSP stream and to play it via the server.

Before the PLAY button is clicked on, the player looks as follows

The player with a video stream being played looks as follows
