1 摘要

FFmpeg 是最常用的跨平台的音频、视频处理软件，但是其通过命令行的方式进行操作对于普通用户而言上手难度大，同时 FFmpeg 只是函数库，对于不同的编程语言，需要自行适配API接口，以便于操作文件。本文介绍SpringBoot 集成 FFmpeg 实现对音视频文件的解析。

FFmpeg 官网: https://ffmpeg.org

FFmpeg Java 平台常用适配仓库:

JavaCV : https://github.com/bytedeco/javacv

JavaCV 是一个集成第三方函数库的平台，包括 OpenCV、FFmpeg 等知名函数库，提供统一的 API 操作，应用广泛。在不考虑应用程序体积大小的情况下推荐使用 JavaCV 作为集成方案。

JAVE2: https://github.com/a-schild/jave2

JAVE2 是将 FFmpeg 进行封装，并提供 Java API 以供用户操作音视频文件的依赖库。用户可以根据软件运行的操作系统来自由选择所需平台的依赖。

本文是基于 JAVE2 依赖来实现解析音视频文件的功能。

2 核心 Maven 依赖

demo-ffmpeg-media/pom.xml

        <!-- ffmpeg 音视频处理 --><dependency><groupId>ws.schild</groupId><artifactId>jave-core</artifactId><version>${schild-ffmpeg.version}</version></dependency><dependency><groupId>ws.schild</groupId><artifactId>jave-nativebin-win64</artifactId><version>${schild-ffmpeg.version}</version></dependency><dependency><groupId>ws.schild</groupId><artifactId>jave-nativebin-linux64</artifactId><version>${schild-ffmpeg.version}</version></dependency><dependency><groupId>ws.schild</groupId><artifactId>jave-nativebin-osx64</artifactId><version>${schild-ffmpeg.version}</version></dependency><dependency><groupId>ws.schild</groupId><artifactId>jave-nativebin-osxm1</artifactId><version>${schild-ffmpeg.version}</version></dependency>

其中 schild-ffmpeg 版本为:

<schild-ffmpeg.version>3.5.0</schild-ffmpeg.version>

这里分别引入了 Windows、Linux、macOS 系统的依赖，可根据软件运行环境进行删减。

3 核心代码

3.1 FFmpeg 解析音视频工具类
