使用本程序可将下载的网易云音乐缓存文件（ncm）转换为 mp3 或 flac 格式

## 简介
|
||||
|
||||
本分支是ncmdump在Android平台上的移植，taglib的android调整改自[taglib-ndk](https://github.com/tumugin/taglib-ndk)
|
||||
|
||||
下为原简介：
|
||||
|
||||
该版本为最早的 C++ 版本，也是作者开发的市面上第一个支持 ncm 转换的程序
|
||||
|
||||
源码复刻自 anonymous5l/ncmdump (2021年10月6日，原作者已经删库)

### 命令行工具
|
||||
|
||||
从 [Release](https://github.com/taurusxin/ncmdump/releases) 下载最新版本的对应系统的已编译好的二进制文件
|
||||
用法与原版相同
|

|
||||
使用 `-h` 或 `--help` 参数来打印帮助

### 动态库
|
||||
|
||||
或者，如果你想利用此项目进行二次开发，例如在你的 C#、Python、Java 等项目中调用，你可以使用 `libncmdump` 动态库，具体使用方法见仓库的 `example` 文件夹
|
||||
|
||||
请注意！如果你在 Windows 下开发，传递到库构造函数的文件名编码**必须为 UTF-8 编码**，否则会抛出运行时错误。

git submodule update --init --recursive

```
|

|

使用 CMake 配置项目。Windows 下若使用 GNU 套件，推荐使用 [msys2](https://www.msys2.org/) 或者 [winlibs](https://winlibs.com/)
|
||||
调整CMakeLists.txt
|
||||
|
||||
```shell
|
||||
# Windows MinGW
|
||||
cmake -G "MinGW Makefiles" -DCMAKE_BUILD_TYPE=Release -B build
|
||||
# Android Studio
|
||||
置于你项目的cpp文件夹下
|
||||
|
||||
# Windows MSVC
|
||||
cmake -G "Visual Studio 17 2022" -A x64 -B build
|
||||
编译Android项目时自动编译，生成numdump和libncmdump.so
|
||||
|
||||
# Linux / macOS
|
||||
cmake -DCMAKE_BUILD_TYPE=Release -B build
|
||||
# 使用
|
||||
```kotlin
|
||||
init {
|
||||
System.loadLibrary("ncmdump") // 你的库名
|
||||
}
|
||||
|
||||
# 如果需要在 macOS 下交叉编译，可以指定 `CMAKE_OSX_ARCHITECTURES` 变量来指明目标系统架构
|
||||
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_OSX_ARCHITECTURES=arm64 -B build # arm64
|
||||
cmake -DCMAKE_BUILD_TYPE=Release -DCMAKE_OSX_ARCHITECTURES=x86_64 -B build # Intel-based
|
||||
external fun DumpFileTo(inputFilePath: String, outputCachePath: String): Int
|
||||
```
|
||||
|
||||
编译项目
|
||||
# DumpFileTo用法
|
||||
inputFilePath：输入文件路径
|
||||
outputCachePath:输出文件路径
|
||||
返回：
|
||||
-1（失败）
|
||||
0（成功）
|
||||
|
||||
```shell
|
||||
# Windows MSVC 需要在构建阶段指定 --config Release
|
||||
cmake --build build -j 8 --config Release
|
||||
|
||||
# Windows MinGW / Linux / macOS
|
||||
cmake --build build -j 8
|
||||
```
|
||||
|
||||
你可以在 `build` 文件夹下找到编译好的二进制文件，以及一个可供其它项目使用的动态库(Windows Only)，使用方法见仓库的 `example` 文件夹
|
||||
# 注意
|
||||
在 Android 11 以上的版本，Android对文件读取和写入有较严格的规定，因此上述目录应为应用私有的目录（比如cache）
