springboot整合富文本编辑器 springboot整合ffmpeg

ffmpeg 下载以及安装步骤

进入官方地址
http://ffmpeg.org/
进入下一步

window 下载

linux 下载

看到上面这个图，下载那个版本看你自己选择

完成之后

window安装

配置环境变量

在cmd 输入ffmpeg 显示下图 就完成了

springboot整合使用

举个例子：
200M的视频，因为太大，网络加载很慢，要等很久。
那么像要播放流畅，那就需要流媒体。
因为视频点播 是流媒体，所以要把视频切成流媒体。
使用ffmpeg 把视频切成m3u8和ts

注意：

是你使用ffmpeg 切成m3u8 ，你要指向这个地址。相等于 localhost/ud/123.mp4.在使用ffmpeg 切片的时候，最终会切成这样子。
