Youtube autoplay does not work for http: scheme

Autoplay for youtube does not work for http: scheme. If you try for example, to develop in http://localhost:3000 won't work because `getYoutubeUrl` does not return scheme. 

One way to bypass this, is to use `data-video-url` with the url of your choice. For example: `https://www.youtube.com/embed/<YOUR_VIDEO_ID>?autoplay=1&<MORE_PARAMS>`
