Strange warnings at yt-dlp Download from vimeo

General system Applications

Today I downloaded a video from vimeo using yt-dlp. It worked, no errors in the video. However, several warnings appeared, the meaning of which I do not understand:

[darius@eos-pc~]$ yt-dlp "https://vimeo.com/803698144"

Can someone please help me out?

If the video did in fact download and is usable you can safely ignore all the warnings. What you are witnessing is the technology war between the content providers who don’t want their stuff stolen and yt-dlp that has dozens of tricks to steal their stuff. It looks like in the case of Vimeo, yt-dlp pulled every trick it has out of the cupboard.

Impersonation

The following provide support for impersonating browser requests. This may be required for some sites that employ TLS fingerprinting.

  • curl_cffi (recommended) - Python binding for curl-impersonate. Provides impersonation targets for Chrome, Edge and Safari. Licensed under MIT
    • Can be installed with the curl-cffi group, e.g. pip install "yt-dlp[default,curl-cffi]"
    • Currently included in yt-dlp.exe, yt-dlp_linux and yt-dlp_macos builds

People don’t do web searches anymore? The link with an explanation is right there.
C’mon man.

What good is this link if I don’t understand it? Why do you think I asked here?

C’mon man.

So this isn’t clear?

Anyway, what @SPOFF said is the longer version of that. So, I guess it wasn’t clear for you.
Everyone’s different. I fail to remember that at times. Apologies. :bowing_man:
