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

The mediaDevices object has the following methods:
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.
navigator.mediaDevices.getUserMedia({
'audio': true,
'video': {
facingMode: 'user'
}
}).then(function(mediaStream) {
// do something with the media stream
});
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.
var constraints = navigator.mediaDevices.getSupportedConstraints();
console.log(constraints);
The iOS implementation that this plugin provides does not allow you to attach the returned MediaStream object to an audio or video tag. Rather you will use the MediaStream object to get a MediaStreamTrack to pass to the Image (see phonegap-plugin-image-capture) or Audio capture API.
