Tartube / yt-dlp / Python / curl_cffi

[televischn]

Hi together,

I'm having a problem with Tartube / yt-dlp / Python / curl_cffi downloading videos for several weeks/months.
Several times I tried to find solutions, but wasn't finally successfull. I'm not an expert, I'm afraid. Perhaps the problem is in the interaction between Tartube / yt-dlp / Python / curl_cffi.

Problem: Some videos cannot be downloaded.
main error:
"WARNING: The extractor specified to use impersonation for this download, but no impersonate target is available. If you encounter errors, then see https://github.com/yt-dlp/yt-dlp#impersonation for information on installing the required dependencies"

I am using Tartube v2.5.197 (current version).
I've tried different things, of course trying to install curl_cffi (but I get an error "ERROR: Failed to build 'curl_cffi' when installing build dependencies for curl_cffi").
I've tried updating Python. I've updated yt-dlp. I've tried another path and separately saved yt-dlp (but then the integrated update in Tartube won't work any longer).
I've searched in various installation guides and issues but couldn't find a solution that worked for me.
I just can guess that I haven't installed everything correctly oder at the wrong folders.

Do you have any hints, how the problem can be solved? Or best practices for handling that error or for correctly embedding yt-dlp, Python and curl_cffi in Tartube?

its because youtube added new algorithms with PO tokens for each video, then we need to use newest ytdlp version. Probably this is in progress here. last 2 days it has been started, and ytdlp released latest docker image with new changes, but without impersonation and with needs to add bgutils lib and impersonation. you can check it https://github.com/yt-dlp/yt-dlp/wiki/PO-Token-Guide
2026.03.03 curl_cffi 0.14.0 - impersonation works fine

I think the problem exists on windows because ytdlp.exe can't solve deno becuase of windows PATH etc issues, but if tartube has been installed as a pip install lib - ytdlp works fine then. Its was my last move and curently on windows it works fine

I see the same error when trying to install curl_cffi manually, in the mingw64 terminal:

I don't know any way to make the install work, so we'll have to wait for the next release of yt-dlp.
