「小程序JAVA实战」小程序视频处理工具ffmpeg（47）

转自；https://idig8.com/2018/09/16/xiaochengxujavashizhanxiaochengxushipinchuligongjuffmpeg46/

前面已经把视频成功的上传到我们的服务器，选择了背景音乐的ID，现在需要把视频和背景音乐进行合并，需要使用一个工具ffmpeg。源码：https://github.com/limingios/wxProgram.git 中wx-springboot 和 No.15

ffmpeg

介绍
>视音频处理工具，跨平台的视音频处理解决方案，主页：http://ffmpeg.org

应用的场景

播放器：射手播放器，暴风影音，迅雷播放器……
转换工具：格式工厂，剪辑工具……
直播，视频加码，滤镜，水印，特效……
