XML File Video Ad

I have a video player with BrightCove, I need assistance creating a XML file that will call a hosted video to play before the player shows. After the hosted video is called, it should then allow you to view the stream that is occurring. The XML file needs to be able to call the video for IOS devices as well as flash devices. I am wanting to create this exact thing except use my video in place of the countdown, then I will need it to go to my player that is embedded on the website. [login to view URL]
