How do I add a full-screen button to mp4 videos?

Report · Mar 05, 2014

I am making a multi-screen HTML 5 help project. We want to add videos. Right now the videos are mp4, but really we could convert them to anything. I want the videos to appear on the page at a nice small specified size. That I can do. However, I want the user to be able to expand the video to a boarderless full-screen size, similar to Youtube videos. I can't find any option to add a full-screen button to the video player. Can it be done in Robohelp? Do I have to buy an external video player?

Thanks.
