Ticket #1948 (closed defect: fixed)
Modify async dispatch to synchronous on Mac and iOS video device implementation

Using asynchronous dispatch to the main queue may cause application to use objects prematurely (such as using UIView before it's initialized). This ticket will fix it by doing the dispatch synchronously instead.
