|

* for your website. An `accessDialogClosed` event will also be dispatched after user clicks on "Allow" or "Block" in the pop-up.
|
|
*
|
|
* The [[Publisher]] object will dispatch an `accessAllowed` or `accessDenied` event once it has been granted access to the requested input devices or not.
|
|
*
|
|
* The [[Publisher]] object will dispatch a `videoElementCreated` event once the HTML video element has been added to DOM (if _targetElement_ not null or undefined)
|
|
*
|
|
* The [[Publisher]] object will dispatch a `videoPlaying` event once the local video starts playing (only if `videoElementCreated` event has been previously dispatched)
|
|
*
|
|
* @param targetElement HTML DOM element (or its `id` attribute) in which the video element of the Publisher will be inserted (see [[PublisherProperties.insertMode]]). If null or undefined no default video will be created for this Publisher
|
|
* (you can always access the native MediaStream object by calling _Publisher.stream.getMediaStream()_ and use it as _srcObject_ of any HTML video element)
|
|
* @param completionHandler `error` parameter is null if `initPublisher` succeeds, and is defined if it fails.
|
|
* `completionHandler` function is called before the Publisher dispatches an `accessAllowed` or an `accessDenied` event
