Add watch together function for video sites
If you are a video site owner, you can add the Watch Together feature to your site by adding just one line of code to introduce JS.
Note that if your site's video player is nested in an iframe, you need to add this line of code to each level of html. Otherwise the plug-in will prompt the page no video.
All code of the project is open source, any questions can join the page under the exchange group consultation.
