what is tiktokdownload fr?

TikTokDownload is a Python tool for downloading videos and other content from TikTok and its Chinese counterpart DouYin, with watermarks removed. The README is primarily in Chinese, but an English version is also available. The tool works from the command line and is aimed at users who want to save content from these platforms in bulk. For DouYin, the tool can fetch and save a user's posted videos, liked videos, favorited items, image collections, short dramas, livestream recordings, and playlist content. It can also download the original audio, cover images, and subtitles for each post. The TikTok side covers a similar set: posted videos, favorites, liked videos, image collections, playlists, and search results. Both platforms require the user to provide authentication cookies so the tool can access account data. Downloads run asynchronously, meaning the tool can process and retrieve multiple files at the same time rather than waiting for each one to finish before starting the next. Other configurable options include choosing a custom save folder, setting file naming templates, applying proxy settings, filtering by date range, and controlling how many items to fetch in a single run. The project includes local implementations of the signature algorithms that TikTok and DouYin use to validate API requests. These are reverse-engineered parameters with names like ABogus, XBogus, and x-tt-params that the platforms check when serving content to apps and browsers. This repository represents an older version of the project. The active development has moved to a related package called F2, which is available separately on PyPI and covers the same platforms with a more modular structure. Installation instructions and documentation are linked from the repository to an external documentation site. The tool supports Windows, macOS, and common Linux distributions.
