capture.captureVideo

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

navigator.device.capture.captureVideo( 
    [CaptureCB](CaptureCB.html) captureSuccess, [CaptureErrorCB](CaptureErrorCB.html) captureError, [CaptureVideoOptions options]
);

Description

This method starts an asynchronous operation to capture video recordings using the device video 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 video recording application, or the maximum number of recordings, specified by the limit parameter in CaptureVideoOptions, 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 video clip.

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

Supported Platforms

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

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 video capture
navigator.device.capture.captureVideo(captureSuccess, captureError, {limit:2});

BlackBerry WebWorks Quirks

  • PhoneGap for BlackBerry WebWorks attempts to launch the Video Recorder application, provided by RIM, to capture the video recordings. The developer will receive a CaptureError.CAPTURE_NOT_SUPPORTED error code if the application is not installed on the device.
