Configuring yt-dlp to Enable Cookies from ungoogled-chromium

Problem

I was trying to download a youtube video with a portable install of yt-dlp using the following command:

yt-dlp "https://www.youtube.com/watch?v=o78RWwgIAN0" --cookies-from-browser chromium --remote-components ejs:npm

because I use ungoogled-chromium and installed deno previously. However, the output said:

Extracting cookies from chromium
ERROR: Could not copy Chrome cookie database. See  https://github.com/yt-dlp/yt-dlp/issues/7271  for more info
ERROR: Could not copy Chrome cookie database. See  https://github.com/yt-dlp/yt-dlp/issues/7271  for more info

Solution

Checking this link, I have to install a plugin called yt-dlp-ChromeCookieUnlock. According to the wiki of yt-dlp, I have to put the package such as [path to yt-dlp.exe]/yt-dlp-plugins/[package name]/yt_dlp_plugins.

It worked perfectly after I did so.

Btw, use --write-thumbnail to download the thumbnails.
