An url that is pointing to an .mp4 h264 encoded video works. Many of the video hosting service are using such video files when displaying videos on the web. However using other not licensed players is forbidden by the terms and conditions of YouTube, therefore we don't have a builtin feature for youtube videos.

I understand that the AR.VideoDrawable method only takes a url to an H.264-encoded video (a URL to a standard YouTube video won't work). Has anyone been able to successfully display YouTube videos as drawable elements?
