ScottSloan/Bili23-Downloader
Bili23 Downloader
Bili23-Downloader is a cross-platform tool designed for downloading high-quality videos, audio streams, and subtitles from the Bilibili platform. It functions as a media downloader and metadata extractor, enabling the backup and archival of online content to local storage.
The project includes a media file organizer that uses custom naming templates to sort content into structured directory systems. It also provides utilities for exporting subtitles and scrolling comments, embedding cover art into video files, and selecting specific resolutions and audio formats.
To increase retrieval speed, the tool utilizes multi-threaded downloading to fetch large video files via parallel connections. It handles media processing by combining separate audio and video streams into standardized container formats and generates descriptive metadata files for use in media center software.
User identity is verified through QR code scanning or SMS messages to grant access to restricted content.
