I am attempting to use a Vimeo video with a video file fallback. The problem I’m having is that I am using the Vimeo Pro account and am hiding the videos from Vimeo.com. There is a setting where I can choose the sites where the video is to be embedded. I have chosen my test domain but the video still does not show. However, if I just use the Vimeo iframe embed code, the video shows fine. Any ideas?
