> a defined translation from one abstraction layer to another
A solution like the aforementioned cannot reliably present a view with a raised level of abstraction, as that necessitates either making unsound assumptions, or being provided with hints (which can be wrong or expire). Just like with code (because they are code).
And so if this is indeed just a rote visualization like that, sticking to the same level of abstraction (thereby not encountering this issue), then they stipulate it is "almost certainly useless, just like they usually are".
I personally find this agreeable, but then I rarely find diagrams particularly illuminating in general, so...
These particular yt-dlp diagrams were an experiment in getting meaningful sequence diagrams from a code repo using Claude. If you open the black tab on the left, you can see the source of the diagrams. Claude was able to generate most of this, albeit with a good amount of back-and-forth to get the details right, plus some manual tweaking in the end.
Do I need to be logged in with a Google account for it to work?
I always, since decades I want to say, ran into troubles whenever I download Youtube vids (no matter which tool I use, yt-dlp or other). It works, then doesn't anymore.
Are you simply, reliably, downloading Youtube vids? How? From a VM? From a container? From your main machine while being logged on?
P.S: congrats to the guys at Google, you sure made that hard
