Have you successfully used ffmpeg on a YouTube video *page* URL before?

I haven't done this in a while, but I seem to recall having to use
youtube-dl to grab the video [1], or the video URL [2].

[2]: https://unix.stackexchange.com/a/282413/227308

Note that the latter may no longer work and return a 403 Forbidden
error nowadays.
