What it is

N_m3u8DL-CLI is a .NET Framework-based command-line downloader for m3u8/HLS/DASH streams that converts them to MP4 or TS format. It handles AES-128-CBC decryption automatically, supports multi-threaded downloads, live stream recording, subtitle/audio track extraction, and binary or FFmpeg-based merging. The project is in maintenance mode, with active development moved to the cross-platform Rust-based N_m3u8DL-RE successor. Monolithic console application structure: N_m3u8DL-CLI/ directory contains all source files including core parsers (Parser.cs, MPDParser.cs), decryption logic (Decrypter.cs, site-specific decoders like DecodeImooc.cs), download orchestration…

Start here

Open these first:

  • N_m3u8DL-CLI/Program.cs — Entry point for the CLI application; defines main command-line argument parsing and orchestration flow.
  • N_m3u8DL-CLI/Parser.cs — Core m3u8/HLS manifest parsing logic that extracts segment URLs and metadata from playlist files.
  • N_m3u8DL-CLI/Downloader.cs — Primary HTTP segment download handler with multi-threading, retry logic, and bandwidth management.
  • N_m3u8DL-CLI/Decrypter.cs — Implements AES-128-CBC decryption for encrypted HLS segments; handles key fetching and cipher initialization.
  • N_m3u8DL-CLI/MPDParser.cs — DASH manifest parser that complements HLS support with MPD format parsing.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone and build with Visual Studio: git clone https://github.com/nilaoda/N_m3u8DL-CLI.git && cd N_m3u8DL-CLI && msbuild N_m3u8DL-CLI.sln. Alternatively, download pre-built release binaries from https://github.com/nila…

Key cautions & unknowns

  • Stale — last commit 3y ago
  • Single-maintainer risk — top contributor 92% of recent commits
  • No tests detected in the complete Git tree
  • FFmpeg dependency: program requires FFmpeg binary in PATH for merging; silent failure if missing. Site-specific decoders: Imooc, Huke88, Ddyun decoders hard-coded; if those sites change encryption, downloads…
  • Published-advisory coverage was unavailable for the captured dependencies.
  • Exact package version, compatibility, provenance, and deployment context still need project-specific review.
