Trick for accessing the camera

HTML/CSS3: getUserMedia

3 types of parameters:


constraints – This should be an object that specifies which media streams you would like to access. For example, to get both video and audio you would use: { video: true, audio: true }
successCallback – A function that will be called if the media stream is successfully loaded. The function will be passed a LocalMediaStream object.
errorCallback (optional) – A function that will be called if the media stream cannot be loaded.

  • You can opt out of the jQuery UI style by adding the attribute data-role="none" to the form element
    • Form will not be styled, not be responsive and certain elements like toggles may not work correctly until you add styling to them.
