ncmdump

历史

项目历史与用法

ncmdump is a small C++ command-line converter for NetEase Cloud Music `.ncm` cache files. Its README describes converting downloaded NCM cache files to MP3 or FLAC and the Homebrew formula packages the same purpose.

项目历史

The GitHub repository was created on 2021-10-06. The README says this C++ version was a cross-platform port and reproduction of the earlier anonymous5l/ncmdump project, which the README says had been deleted, and claims it was the earliest C++ version and first program on the market to support NCM conversion. Version 1.3.0 is called out in the README for fixing filenames containing UTF-8 characters such as Chinese, Japanese, Korean, and emoji, and for adding DLL builds for use from other languages.

采用历史

ncmdump's adoption is concentrated in the NetEase Cloud Music ecosystem and Chinese-language toolchains. The GitHub page observed for this batch showed about 4.1k stars and 488 forks, while Homebrew, MacPorts, and winget packaging make the CLI available outside ad-hoc binary downloads. The Homebrew formula API response consulted for this July 2026 batch reported 68 install-on-request events in 30 days and 649 in 365 days.

使用方式

The README documents single-file conversion, multiple input files, directory mode with `-d`, recursive traversal with `-r`, output selection with `-o`, source deletion after successful processing with `-m`, and version/help flags. The maintainer has clarified in GitHub Discussions that the tool decrypts and extracts the original MP3 or FLAC data from the `.ncm` file rather than transcoding between formats.

为什么软件包爱好者会关心

ncmdump is a format-escape utility: valuable when a user's music files are locked in NetEase's `.ncm` wrapper and they want normal player/library compatibility. It is niche, but the packaging story matters because users often need a trusted binary instead of random converter sites.
