初识MPV播放器
MPV简介
MPV是基于MPlayer的图形界面版本，它继承了MPlayer强大的解码能力和高度的可定制性。MPV支持多种视频格式，包括MKV、MP4、AVI等，并且可以播放流媒体内容。
MPV的特点
- 轻量级：MPV的安装包小，运行效率高。
- 跨平台：支持Windows、Linux、macOS等多种操作系统。
- 可定制性：用户可以通过配置文件进行高度定制。
- 丰富的插件系统：支持多种插件，扩展播放器的功能。
MPV源码入门
源码获取
首先，你需要从MPV的官方网站下载源码。MPV使用Git进行版本控制，你可以通过以下命令克隆仓库：
git clone https://github.com/mpv-player/mpv.git
项目结构
MPV的源码结构如下：
mpv/
├── doc/
├── src/
│ ├── audio/
│ ├── core/
│ ├── demux/
│ ├── gui/
│ ├── input/
│ ├── osd/
│ ├── plugin/
│ ├── video/
│ └── utils/
├── winbuild/
└── w32/
每个目录都有其特定的功能，例如src/audio/包含音频解码和输出相关的代码，src/video/包含视频解码和输出相关的代码。
编译环境
编译MPV需要安装一系列依赖库，包括FFmpeg、SDL2、libass等。以下是在Linux上编译MPV的示例：
