Media

The Media object provides the ability to record and play back audio files on a device.

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

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.

Parameters

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

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 audio file.
media.pause: Pause playing audio file.
media.release: Releases the underlying OS'es audio resources.
media.seekTo: Moves the position within the audio file.
media.startRecord: Start recording audio file.
media.stopRecord: Stop recording audio file.
media.stop: Stop playing 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.

BlackBerry WebWorks Quirks

BlackBerry devices support a limited number of simultaneous audio channels. CDMA devices only support a single audio channel. Other devices support up to two simultaneous channels. Attempting to play more audio files then the supported amount will result in previous playback being stopped.

iOS Quirk

numberOfLoops

Pass in 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 play the audio of the media file when the screen is locked (this defaults to true if not set). If this is set to true, it will ignore the state of the hardware mute button. e.g:
```
var myMedia = new Media("http://audio.ibeat.org/content/p1rj1s/p1rj1s_-_rockGuitar.mp3")
myMedia.play({ playAudioWhenScreenIsLocked : false })
```

media.release

Releases the underlying operating systems audio resources.

media.release();

Description

Function media.release is a synchronous function that releases the underlying operating systems audio resources. This function is particularly important for Android as there are a finite amount of OpenCore instances for media playback. Developers should call the 'release' function when they no longer need the Media resource.

Supported Platforms

Android
BlackBerry WebWorks (OS 5.0 and higher)
iOS
Windows Phone 7 ( Mango )

Quick Example

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

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