Once we developed app for Mobile Device with Adobe Air, we need embed the Youtube video to the app. For easiest way, we use StageWebView of AIR, so we can directly load Youtube Embed video like a frame.
It used to be working. But from today, it suddenly not working. the video just show the blank screen or "An error occurred while performing this operation." message.
I think Youtube may change some setting of its video pages. The youtube homepage or search page are still working in StageWebView.
