📋 Prerequisites

Optional Dependencies

Wrapper

Run the Wrapper v2 server for wrapper-backed account, playback, and decryption requests. Enable it with --use-wrapper or use_wrapper = true. Configure wrapper HTTP account/playback calls with --wrapper-url or wrapper_url, and configure WV2D batch TCP decrypt with --wrapper-decrypt-host / --wrapper-decrypt-port.

gamdl builds a private Rust extension from gamdl/downloader/ammuxer as gamdl._ammuxer. That native media engine handles wrapper TCP decrypt/reassembly plus MP4/M4A writing and muxing; Python remains responsible for the CLI, downloads, metadata tagging, and high-level orchestration.

The wrapper is recommended when using the alac song codec. ALAC can be attempted without wrapper, but it probably won't work due to API limitations.

Note:

• When using the Wrapper, you'll be asked to insert your credentials to login if you haven't already.
• Newer wrapper-v2 builds use HTTP JSON for account/playback and WV2D batch TCP port 10020 for decrypt.
• Song codecs other than alac do not require the wrapper.
• Cookies can be skipped when using the wrapper.

N_m3u8DL-RE

Use N_m3u8DL-RE as a faster download alternative to the default yt-dlp download mode. Enable it with --download-mode nm3u8dlre or download_mode = nm3u8dlre.

If the executable is not available in your system PATH, set its location with --nm3u8dlre-path or nm3u8dlre_path.

N_m3u8DL-RE also needs FFmpeg. If the FFmpeg executable is not available in your system PATH, set its location with --ffmpeg-path or ffmpeg_path.

📦 Installation

1. Install Gamdl via pip:

   pip install gamdl-ext
   

2. Set up the cookies file:

   • Place the cookies file in the working directory as cookies.txt, or
   • Specify the path using --cookies-path or in the config file

3. Optional: Set up dependencies (only if you need the functionality) See the Optional Dependencies section to determine which optional tools you need.
