phonegap-plugin-media-stream 
This plugin provides an implementation of the W3C Media Capture API which allows authorized web applications to access streams from the device's audio and video capturing interfaces, i.e. to use the data available from the camera and the microphone. The streams exposed by the API can be bound directly to the HTML or elements or read and manipulated in the code, including further more specific processing via Image Capture API, Media Recorder API or Real-Time Communication.
Installation
phonegap plugin add phonegap-plugin-media-stream
phonegap plugin add https://github.com/phonegap/phonegap-plugin-media-stream.git
The mediaDevices Object
The mediaDevices object has the following methods:
getUserMedia(optional MediaStreamConstraints constraints)
The getUserMedia method call prompts the user for permission to capture audio or video input. The method returns a promise that when resolved returns a MediaStream object. You can constrain what type of media streams are return by passing in an option MediaStreamConstraints object.
Example
navigator.mediaDevices.getUserMedia({
'audio': true,
'video': {
facingMode: 'user'
}
}).then(function(mediaStream) {
// do something with the media stream
});
getSupportedConstraints()
The getSupportedConstraints method returns an object which describes which constraints the device supports. You can check the constraints before making a call to getUserMedia to make sure that the functionality you want is supported.
Example
var constraints = navigator.mediaDevices.getSupportedConstraints();
console.log(constraints);
Quirks
The iOS implementation that this plugin provides does not allow you to attach the returned MediaStream object to a audio or video tag. Rather you will use the MeidaStream object to get a MediaStreamTrack to pass to the Image (see phonegap-plugin-image-capture) or Audio capture API.
