Description
This userscript will allow you to open videos in external player mpv by simply clicking on a thumbnail without loading bloated video page with web player.
How it works
It simply replaces video thumbnail hyperlinks on a page, changing their protocol from https:// to mpv:// and coding the original URL as base64. The result string is then passed to mpv:// URI handler as base64 string.
Prerequisites in your system
Keep in mind that these instructions are valid for GNU/Linux operating system for now. If you are using proprietary Windows, you are on your own.
Supported sites
Potentially it works with anything that mpv and its youtube-dl backend supports. But in order to add support for a certain website, one needs to find its DOM selector for site specific video thumnails and put it into the dictionary inside the userscript
