cordova-plugin-media-custom v0.2.0

cordova-plugin-media-custom

A plugin for Cordova hybrid apps which allows custom overlays on the Video Camera. Based on the Camera2Video example by the Android team.

The following technologies are used in the app:

• Apache Cordova http://cordova.apache.org/
• Camera2Video http://developer.android.com/samples/Camera2Video/index.html

Installation and running tasks

Install Apache Cordova then either navigate to a project or run the command:

First open an exisiting project or create a new project using:

cordova create hello com.example.hello HelloWorld

Now navigate into the main directory and add this plugin using:

cordova plugin add cordova-plugin-media-custom

Or use the command:

cordova plugin add https://github.com/kmturley/cordova-plugin-media-custom.git

And use Javascript in your html page to call the plugin:

window.MediaCustom.show(function (data) {
    window.alert('user recorded a video: ' + data);
    window.MediaCustom.hide();
}, function () {
    window.alert('user clicked on the gallery button');
});

Full example utilising the custom camera:

<a href="#" class="button" id="open">Open Camera</a>
<div class="video-container">
    <video src="assets/intro.mp4" id="video" autoplay controls></video>
</div>
<div id="output">
    <h2>Metadata</h2>
</div>
<script src="cordova.js"></script>
<script>
    document.addEventListener('deviceready', function() {
        var video = document.getElementById('video'),
            output = document.getElementById('output');

        video.addEventListener('loadeddata', function (e) {
            // for some reason we need a delay to successfully retrieve metadata
            window.setTimeout(function () {
                output.innerHTML += 'src = ' + e.target.src + '<br/>';
                output.innerHTML += 'duration = ' + e.target.duration + '<br/>';
                output.innerHTML += 'videoWidth = ' + e.target.videoWidth + '<br/>';
                output.innerHTML += 'videoHeight = ' + e.target.videoHeight + '<br/>';
            }, 200);
        });

        document.getElementById('open').addEventListener('click', function () {
            if (window.MediaCustom) {
                window.MediaCustom.show(function (data) {
                    video.src = data;
                    window.MediaCustom.hide();
                }, function (e) {
                    //window.alert('MediaCustom.error: ' + JSON.stringify(e));
                    window.MediaCustom.hide();
                    navigator.camera.getPicture(function (data) {
                        //window.alert('getPicture.success: ' + JSON.stringify(data));
                        video.src = data;
                    }, function (e) {
                        window.alert('getPicture.error: ' + JSON.stringify(e));
                    }, {
                        sourceType: Camera.PictureSourceType.PHOTOLIBRARY,
                        mediaType: Camera.MediaType.VIDEO,
                        destinationType: Camera.DestinationType.FILE_URI
                    });
                });
            } else {
                window.alert('MediaCustom feature not supported');
            }
        });

        document.addEventListener('backbutton', function (e) {
            e.preventDefault();
            window.alert('back pressed');
        }, false);
    });
</script>

Testing the plugin using plugman:

npm install -g plugman
plugman install --platform android --project www --plugin plugins/cordova-plugin-media-custom

Cordova caches plugins, So if you make any changes to a plugin's code you can force a reset using the following command:

cordova platform remove android; cordova platform add android; cordova run android

Android Studio ignore camera output regex:

^(?!(mm-camera|Camera3-Device|Camera3-OutputStream|BufferQueueProducer))

Command to take a screenshot of a connected android device:

adb shell screencap -p | perl -pe 's/\x0D\x0A/\x0A/g' > screen.png

Command to capture video from a connected android device screen:

adb shell screenrecord --verbose /sdcard/ExampleName.mp4
