Hello, Few years ago Yuchen Pei started to develop emms-info-ytdl (branch info-ytdl), which provides info for links like: https://www.youtube.com/watch?v=.....
I do not know why these changes where not accepted in master. Perhaps it is because ytdl is called synchronously, and therefore emms-info-ytdl freezes Emacs. For a few years i am using without any problem the version, which works asynchronously. Please find attached the asynchronous version of emms-info-ytdl. I am not programmer, so maybe there are some style things. With some guidance, i am ready to correct them. I hope it can be added in emms.
