I'm glad that a new non-legacy version of this extension is available. I got everything to work, including adding the path to ffmpeg. Everything works like in the previous add-on. However, there's only 1 thing this one is missing: hiding filetypes of the available video downloads. I never use 3gp or WebM filetypes. I was able to hide these in the old add-on. Now these add extra "cluster" to the filetypes to download inside the video. Not a deal breaker, just extra annoyance over the old one.
