This function generates a pure video instance.

Syntax: genVideo( VideoServiceProvider, VideoID, VideoWidth, VideoHeight, VideoAlign, VideoCaption, URLArgs )

• VideoServiceProvider: Optional. The video service provider. If not set, youtube will used.
• VideoID: A video ID. If not set, this function will directly return a nil value.
• VideoWidth: Optional. The width of the video instance, non-number will be ignored, defaults to 425.
• VideoHeight: Optional. The height of the video instance, non-number will be ignored. If not set, it will be calculated by width automatically to keep aspect ratio to 16:9.
