I've had my developers create a video sitemap. They are able to add all required tags with the exception of the raw video file URL/location OR player URL.This is because there is no raw video file in the system/back-end. They pass  parameters to an API and render the video in the page.So, in my mind this renders the sitemap useless. Thoughts?
