M3u8 Downloader
m3u8-downloader is a tool for extracting, downloading, and merging video segments from m3u8 playlist files into a single file. It functions as an HLS stream extractor and downloader that parses playlists to identify and retrieve individual video fragments.
The project features a dedicated AES-128 stream decryptor to ensure encrypted media is playable and utilizes an MP4 transcoder to convert fragmented stream segments into a standard container for broad media player compatibility. It employs cross-origin script injection to bypass browser security restrictions and extract video source links directly from hosting websites.
Additional capabilities include fragment-level retry logic to recover missing or corrupted segments and incremental assembly that allows for partial download previewing before a stream is fully complete. The system also supports automated stream capture via target URLs or userscripts.
Features
- Video Downloaders - Extracts, downloads, and merges HLS video segments from m3u8 playlists into local files.
