If you’re looking to incorporate audio, video, and image capturing capabilities into your mobile applications, the Cordova Plugin Media Capture is a powerful tool that allows you to achieve just that. In this guide, we’ll break down how to use this plugin effectively, along with troubleshooting ideas to help you along the way.

Getting Started with Media Capture Plugin

The Cordova Plugin Media Capture provides seamless access to the audio, image, and video capture capabilities of a device. Below is the step-by-step guide to set it up.

Installation

• Firstly, ensure you have Cordova installed.
• Run the following command in your terminal to add the Media Capture plugin:

cordova plugin add cordova-plugin-media-capture

Using Media Capture

Once installed, you can use the plugin to capture audio, images, or videos. But before using it, you must wait until the device is ready.

document.addEventListener('deviceready', onDeviceReady, false);

function onDeviceReady() {
    console.log(navigator.device.capture);
}

Analogy: Understanding Media Capture

Imagine you are in a restaurant, and you want to order a meal, a drink, and a dessert. The restaurant employs a waiter (the Media Capture plugin) who takes your order (your request to capture audio, video, or images). The waiter goes to the kitchen (the device’s capabilities) to get what you requested. If everything runs smoothly, you receive your order (captured media) without problems. However, if the kitchen is backed up, or if you’ve ordered something that isn’t on the menu, the waiter will come back to inform you about it (error callbacks).

Capturing Audio, Image, and Video

The plugin allows for capturing audio, images, and videos asynchronously. Below are the methods to execute these actions:

Capture Audio

• To start audio capture:

navigator.device.capture.captureAudio(captureSuccess, captureError, options);

Capture Image

• To capture an image:

navigator.device.capture.captureImage(captureSuccess, captureError, options);

Capture Video

• To capture video:

navigator.device.capture.captureVideo(captureSuccess, captureError, options);

Handling Callbacks

Make sure to handle the success and error scenarios by defining appropriate callback functions:

var captureSuccess = function(mediaFiles) {
    for (var i = 0; i < mediaFiles.length; i += 1) {
        var path = mediaFiles[i].fullPath;
        // Do something interesting with the file
    }
};

var captureError = function(error) {
    navigator.notification.alert('Error code: ' + error.code, null, 'Capture Error');
};

Troubleshooting

While using the Media Capture plugin, you may encounter some issues. Here are troubleshooting ideas that can help:

• Check that your app's privacy policy adheres to relevant requirements, particularly if you access the camera or microphone.
• Ensure that you have implemented "Just-in-Time" notices where required by the app marketplace.
• If an error occurs, check your callback functions to make sure they are set up correctly.
• Follow platform-specific quirks outlined in the documentation, especially on iOS and Android.
