Install QUANTEEC for CastLabs PRESTOPlay​

3 steps:

1- Import the QUANTEEC library for CastLabs PRESTOPlay player in your webpage:

<script src="https://files.quanteec.com/quanteec/latest/quanteec-castlabs.min.js"></script>

2- Adjust the QUANTEEC configuration to your quanteecKey and specific options:

var quanteecConfig = { 
    quanteecKey: "<your-quanteec-key>" 
};
info

To create a new QUANTEEC configuration and/or retrieve your default QUANTEEC key, you must first go to the Config page of your panel.

note

A complete description of the possible options of the quanteecConfiguration object can be found here.

warning

In your QUANTEEC configuration, remember to set a different videoID if you have different formats of the same stream (e.g., one DASH stream and one HLS stream) or two variants of the same stream (one stream with English audio and one stream with another language).

3- Link QUANTEEC to CastLabs PRESTOPlay right after the creation of the CastLabs PRESTOPlay player instance:

var player = new clpp.Player('video', { license: 'your_licence_key' });
var quanteec = new Quanteec(quanteecConfig, player);
danger

QUANTEEC Loading order​

The creation of the QUANTEEC object with new Quanteec must be executed BEFORE the launch of the video by the player. Be careful to not create it AFTER player.load, for example, by calling it asynchronously

Here is a complete example of the use of QUANTEEC for CastLabs PRESTOPlay:

<!DOCTYPE html>
<html>
    <head>
        <script src="dist/cjs/cl.core.js"></script>
        <script src="dist/cjs/cl.mse.js"></script>
        <script src="dist/cjs/cl.dash.js"></script>
        <!-- 1- Import the QUANTEEC plugin -->
        <script src="https://files.quanteec.com/quanteec/latest/quanteec-castlabs.min.js"></script>
    </head>

    <body>
        <div id="videoplayer"></div>

        <script>
            document.addEventListener("DOMContentLoaded", function () {
                
                var videoSource = "https://example.com/videoSource.mpd";

                let player = new clpp.Player('videoplayer', { license: '<your_license_here>' });
                player.use(clpp.dash.DashComponent);
                player.use(clpp.hls.HlsComponent);


                // 2- Adjust QUANTEEC configuration
                var quanteecConfig = {
                    quanteecKey: "<your-quanteec-key>", 
                    videoID: "<enter-your-custom-videoID>" // [Optional but recommended] String --> specific name to identify a video. Useful if the videosource url contains a token which is different for every user. By default: the videoSource value is used.
                };


                // 3- Link QUANTEEC to CastLabs PRESTOPlay player after the creation of the CastLabs PRESTOPlay player instance, protected by a try catch
                    var quanteecPlayer = ""
                    try {
                        quanteecPlayer = new Quanteec(quanteecConfig, player);
                    } catch(err) {
                        // If QUANTEEC is not available or an unusual issue occurs
                    }

                player.load({
                    source: '//demo.cf.castlabs.com/media/prestodash/Manifest.mpd',
                    autoplay: false,
                    muted: true
                });

            });
        </script>
    </body>
</html>

tip

Good practice: try-catch block​

One good practice is to encapsulate the instantiation of the QUANTEEC object within a try-catch block. This approach provides a robust mechanism for handling situations where QUANTEEC might not be available or may encounter compatibility issues.

Script loading​

Embedding QUANTEEC on a webpage involves loading an external script. If, for any reason, this script fails to load or execute correctly, an error may occur. Wrapping the instantiation of the QUANTEEC object in a try-catch block allows you to catch and handle these errors gracefully.

Unusual environments​

Web environments are diverse, and unusual browsers or plugin associations might cause issues with QUANTEEC. By encapsulating the new Quanteec() operation in a try-catch block, you can account for scenarios where QUANTEEC is either unavailable or incompatible with the current browser, preventing unhandled exceptions.
