Capture

Provides access to the audio, image, and video capture capabilities of the device.

Objects

Capture
CaptureAudioOptions
CaptureImageOptions
CaptureVideoOptions
CaptureCB
CaptureErrorCB
ConfigurationData
MediaFile
MediaFileData

Methods

capture.captureAudio
capture.captureImage
capture.captureVideo
MediaFile.getFormatData

Scope

The capture object is assigned to the navigator.device object, and therefore has global scope.

// The global capture object
var capture = navigator.device.capture;

Properties

supportedAudioModes: The audio recording formats supported by the device. (ConfigurationData[])
supportedImageModes: The recording image sizes and formats supported by the device. (ConfigurationData[])
supportedVideoModes: The recording video resolutions and formats supported by the device. (ConfigurationData[])

Methods

capture.captureAudio: Launch the device audio recording application for recording audio clip(s).
capture.captureImage: Launch the device camera application for taking image(s).
capture.captureVideo: Launch the device video recorder application for recording video(s).

Supported Platforms

Android
BlackBerry WebWorks (OS 5.0 and higher)

capture.captureAudio

Start the audio recorder application and return information about captured audio clip file(s).

navigator.device.capture.captureAudio(
CaptureCB captureSuccess, CaptureErrorCB captureError, [CaptureAudioOptions options]
);

Description

This method starts an asynchronous operation to capture audio recordings using the device's default audio recording application. The operation allows the device user to capture multiple recordings in a single session.

The capture operation ends when either the user exits the audio recording application, or the maximum number of recordings, specified by the limit parameter in CaptureAudioOptions, has been reached. If no value is provided for the limit parameter, a default value of one (1) is used, and the capture operation will terminate after the user records a single audio clip.

When the capture operation is finished, it will invoke the CaptureCB callback with an array of MediaFile objects describing each captured audio clip file. If the operation is terminated by the user before an audio clip is captured, the CaptureErrorCB callback will be invoked with a CaptureError object with the CaptureError.CAPTURE_NO_MEDIA_FILES error code.
Supported Platforms

Quick Example

// capture callback
var captureSuccess = function(mediaFiles) {
var i, path, len;
for (i = 0, len = mediaFiles.length; i < len; i += 1) { path = mediaFiles[i].fullPath; // do something interesting with the file } }; // capture error callback var captureError = function(error) { navigator.notification.alert('Error code: ' + error.code, null, 'Capture Error'); }; // start audio capture navigator.device.capture.captureAudio(captureSuccess, captureError, {limit:2}); Full Example
