I’m not a programmer so I’m probably not using the right words but when I’m in Firefox and press F12 to get to the console (?) where can I find the address of the video that’s currently displayed on the page (to download with wget or yt-dlp)? I tried element picker but nothing that looks like an address appeared.
TIA!


Different mechanisms.
If it’s YT (or a yt embed) just use yt-dlp. Same goes for many, many other sites. Other comments describe how to do that.
If not, try what @danielsiepmann@friendica.daniel-siepmann.de recommends. However, sites use all sorts of tricks like providing the video in chunks, or hiding the actual video URL behind so much javascript that a human just can’t get at it, or requiring authentication etc.
