cordova-plugin-media

Fork from https://github.com/ghenry22/cordova-plugin-media.git#avplayer_streaming

This plugin provides the ability to record and play back audio files on a device.

NOTE: The current implementation does not adhere to a W3C specification for media capture, and is provided for convenience only. A future implementation will adhere to the latest W3C specification and may deprecate the current APIs.

This plugin defines a global Media Constructor.

Although in the global scope, it is not available until after the deviceready event.

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
    console.log(Media);
}

Windows Phone Quirks

Only one media file can be played back at a time.
There are strict restrictions on how your application interacts with other media. See the Microsoft documentation for details.

Media

var media = new Media(src, mediaSuccess, [mediaError], [mediaStatus]);

Parameters

src: A URI containing the audio content. (DOMString)
mediaSuccess: (Optional) The callback that executes after a Media object has completed the current play, record, or stop action. (Function)
mediaError: (Optional) The callback that executes if an error occurs. (Function)
mediaStatus: (Optional) The callback that executes to indicate status changes. (Function)

Constants

The following constants are reported as the only parameter to the mediaStatus callback:

Media.MEDIA_NONE = 0;
Media.MEDIA_STARTING = 1;
Media.MEDIA_RUNNING = 2;
Media.MEDIA_PAUSED = 3;
Media.MEDIA_STOPPED = 4;

Methods

media.getCurrentPosition: Returns the current position within an audio file.
media.getDuration: Returns the duration of an audio file.
media.play: Start or resume playing an audio file.
media.pause: Pause playback of an audio file.
media.release: Releases the underlying operating system's audio resources.
media.seekTo: Moves the position within the audio file.
media.setVolume: Set the volume for audio playback.
media.startRecord: Start recording an audio file.
media.stopRecord: Stop recording an audio file.
media.stop: Stop playing an audio file.

Additional ReadOnly Parameters

position: The position within the audio playback, in seconds.
- Not automatically updated during play; call getCurrentPosition to update.
duration: The duration of the media, in seconds.

media.getCurrentPosition

Returns the current position within an audio file. Also updates the Media object's position parameter.

media.getCurrentPosition(mediaSuccess, [mediaError]);

Parameters

mediaSuccess: The callback that is passed the current position in seconds.
mediaError: (Optional) The callback to execute if an error occurs.

Quick Example

// Audio player
//
var my_media = new Media(src, onSuccess, onError);

// Update media position every second
var mediaTimer = setInterval(function () {
    // get media position
    my_media.getCurrentPosition(
        // success callback
        function (position) {
            if (position > -1) {
                console.log((position) + " sec");
            }
        },
        // error callback
        function (e) {
            console.log("Error getting pos=" + e);
        }
    );
}, 1000);

media.getDuration

Returns the duration of an audio file in seconds. If the duration is unknown, it returns a value of -1.

media.getDuration();

Quick Example

// Audio player
//
var my_media = new Media(src, onSuccess, onError);

// Get duration
var counter = 0;
var timerDur = setInterval(function() {
    counter = counter + 100;
    if (counter > 2000) {
        clearInterval(timerDur);
    }
    var dur = my_media.getDuration();
    if (dur > 0) {
        clearInterval(timerDur);
        document.getElementById('audio_duration').innerHTML = (dur) + " sec";
    }
}, 100);

media.pause

Pauses playing an audio file.

media.pause();

Quick Example

// Play audio
//
function playAudio(url) {
    // Play the audio file at url
    var my_media = new Media(url,
        // success callback
        function () { console.log("playAudio():Audio Success"); },
        // error callback
        function (err) { console.log("playAudio():Audio Error: " + err); }
    );

    // Play audio
    my_media.play();

    // Pause after 10 seconds
    setTimeout(function () {
        media.pause();
    }, 10000);
}

media.play

Starts or resumes playing an audio file.

media.play();

Quick Example

// Play audio
//
function playAudio(url) {
    // Play the audio file at url
    var my_media = new Media(url,
        // success callback
        function () {
            console.log("playAudio():Audio Success");
        },
        // error callback
        function (err) {
            console.log("playAudio():Audio Error: " + err);
        }
    );
    // Play audio
    my_media.play();
}

iOS Quirks

numberOfLoops: Pass this option to the play method to specify the number of times you want the media file to play, e.g.:

  var myMedia = new Media("http://audio.ibeat.org/content/p1rj1s/p1rj1s_-_rockGuitar.mp3")
  myMedia.play({ numberOfLoops: 2 })

playAudioWhenScreenIsLocked: Pass in this option to the play method to specify whether you want to allow playback when the screen is locked. If set to true (the default value), the state of the hardware mute button is ignored, e.g.:
```
  var myMedia = new Media("http://audio.ibeat.org/content/p1rj1s/p1rj1s_-_rockGuitar.mp3")
  myMedia.play({ playAudioWhenScreenIsLocked : false })
```
order of file search: When only a file name or simple path is provided, iOS searches in the www directory for the file, then in the application's documents/tmp directory:
```
  var myMedia = new Media("audio/beer.mp3")
  myMedia.play()  // first looks for file in www/audio/beer.mp3 then in <application>/documents/tmp/audio/beer.mp3
```

media.release

Releases the underlying operating system's audio resources. This is particularly important for Android, since there are a finite amount of OpenCore instances for media playback. Applications should call the release function for any Media resource that is no longer needed.

media.release();

Quick Example

// Audio player
//
var my_media = new Media(src, onSuccess, onError);

my_media.play();
my_media.stop();
my_media.release();

media.seekTo

Sets the current position within an audio file.

media.seekTo(milliseconds);

Parameters

milliseconds: The position to set the playback position within the audio, in milliseconds.

Quick Example

// Audio player
//
var my_media = new Media(src, onSuccess, onError);
    my_media.play();
// SeekTo to 10 seconds after 5 seconds
setTimeout(function() {
    my_media.seekTo(10000);
}, 5000);

BlackBerry 10 Quirks

Not supported on BlackBerry OS 5 devices.

media.setVolume

Set the volume for an audio file.

media.setVolume(volume);

Parameters

volume: The volume to set for playback. The value must be within the range of 0.0 to 1.0.

Supported Platforms

Android
iOS

Quick Example

// Play audio
//
function playAudio(url) {
    // Play the audio file at url
    var my_media = new Media(url,
        // success callback
        function() {
            console.log("playAudio():Audio Success");
        },
        // error callback
        function(err) {
            console.log("playAudio():Audio Error: "+err);
    });

    // Play audio
    my_media.play();

    // Mute volume after 2 seconds
    setTimeout(function() {
        my_media.setVolume('0.0');
    }, 2000);

    // Set volume to 1.0 after 5 seconds
    setTimeout(function() {
        my_media.setVolume('1.0');
    }, 5000);
}

media.startRecord

Starts recording an audio file.

media.startRecord();

Supported Platforms

Android
iOS
Windows Phone 7 and 8
Windows

Quick Example

// Record audio
//
function recordAudio() {
    var src = "myrecording.mp3";
    var mediaRec = new Media(src,
        // success callback
        function() {
            console.log("recordAudio():Audio Success");
        },

        // error callback
        function(err) {
            console.log("recordAudio():Audio Error: "+ err.code);
        });

    // Record audio
    mediaRec.startRecord();
}

Android Quirks

Android devices record audio in Adaptive Multi-Rate format. The specified file should end with a .amr extension.
The hardware volume controls are wired up to the media volume while any Media objects are alive. Once the last created Media object has release() called on it, the volume controls revert to their default behaviour. The controls are also reset on page navigation, as this releases all Media objects.

iOS Quirks

iOS only records to files of type .wav and returns an error if the file name extension is not correct.
If a full path is not provided, the recording is placed in the application's documents/tmp directory. This can be accessed via the File API using LocalFileSystem.TEMPORARY. Any subdirectory specified at record time must already exist.
Files can be recorded and played back using the documents URI:
```
  var myMedia = new Media("documents://beer.mp3")
```

Windows Quirks

Windows devices can use MP3, M4A and WMA formats for recorded audio. However in most cases it is not possible to use MP3 for audio recording on Windows Phone 8.1 devices, because an MP3 encoder is not shipped with Windows Phone.
If a full path is not provided, the recording is placed in the AppData/temp directory. This can be accessed via the File API using LocalFileSystem.TEMPORARY or 'ms-appdata:///temp/' URI.
Any subdirectory specified at record time must already exist.

Tizen Quirks

Not supported on Tizen devices.

media.stop

Stops playing an audio file.

media.stop();

// Play audio
//
function playAudio(url) {
    // Play the audio file at url
    var my_media = new Media(url,

        function() {
            console.log("playAudio():Audio Success");
        },
        // error callback
        function(err) {
            console.log("playAudio():Audio Error: "+err);
        }
    );

    // Play audio
    my_media.play();

    // Pause after 10 seconds
    setTimeout(function() {
