+## 编译器
+由于本项目计划在不同平台上均可使用，因此需要对常见的平台的编译器进行配置。   
+### aarch64-none-linux-gnu
+```bash
+wget https://armkeil.blob.core.windows.net/developer/Files/downloads/gnu/12.2.rel1/binrel/arm-gnu-toolchain-12.2.rel1-x86_64-aarch64-none-linux-gnu.tar.xz
+```
+
+## 第三方库编译
+本项目涉及第三方库主要是opencv、ffmpeg、x264.   
+### 编译环境：
+#### x86_64 平台编译环境
+- 操作系统： Debian12(Linux 5.15)   
+- GCC/G++ version : 12.2.0   
+- cmake version : 3.25.1   
+- make version : 4.3   
+
+#### arm64平台交叉编译环境
+- Host 平台： x86_64   
+- Target 平台： aarch64   
+- 交叉编译器： arm官方，aarch64-none-linux-gnu   
+- GCC/G++ version : 12.2.1   
+
+### x264 编译
+源码下载：
