The verto.clientReady event calls the onMessage callback function passed in
the Verto object. We should check for the existence of this callback function
before trying to call it.
The Verto libs currently have total control over the streams associated with
placing any kind of call, handling both their creation and teardown
automatically.
This patch provides the option for a developer to instead pass pre-created
MediaStream objects when instantiating the Verto object, or when calling
Verto.newCall(), and the library will bypass the work of creating those
streams, and of destroying those streams when the call is torn down.
This is particularly useful if the application wants to manage its own streams,
such as re-using them in other non-Verto aspects of the application.
The patch also creates some internal convenience functions for managing the
video element related to a local video stream.
This patch adds an onRemoteStream callback, which can be specified on the Verto
instance, or per dialog. The callback is fired when the remote stream from a
call is received, and receives two arguments, the first is the remote stream,
the second is the Verto dialog object.
$.verto.unloadJobs queue leverages the 'beforeunload' event to perform work
prior to browser page unload.
However, iOS does not support that event. Its equivalent event is 'pagehide'.
This patch uses the pagehide event on iOS, and beforeunload for all others.
Verto.newCall() permits passing custom callback functions per call that
override the default dialog callbacks inherited from the Verto object.
However, they are currently set after calling the invite() function, and it's
possible that some of these callbacks could be called during the invite()
function's execution.
To avoid a race condition, move setting these custom callbacks on the dialog
to happen before calling invite().
Currently the 'permissionCallback' object is only available at the Verto
instance level. This is problematic in multi-call scenarios, where an
individual call dialog needs access to the onGranted/onDenied callback
functions.
The patch adds a check for existence of onGranted/onDenied callback functions
at the dialog level, with a fallback to the original behavior of calling
onGranted/onDenied from the Verto instance if it's not available on the dialog.
This preserves backwards compatibility while allowing per-dialog overrides
going forward.
Previously, users implementing a Verto workflow where both user login and
placing a new call are automated (eg., visiting a URL, and the videoconference
loads automatically) faced the challenge of not having a reliable way to know
that a page load will result in Verto's call recovery mechanism reconnecting
an existing detached call or not.
This adds a verto.clientReady JSON-RPC message, emitted after all calls are
re-attached, which contains a 'reattached_sessions' array, containing the
sess_id of any reattached session.
Client side, this can be caught in the onMessage handler, under the
$.verto.enum.message.clientReady key.
added onGrant/onDenied callbacks in onStream/onError of RTCCallbacks
