ffmpeg-demo 当前对应的 gitee代码

Spring boot视频播放(解决MP4大文件无法播放)，整合ffmpeg,用m3u8切片播放。

springboot 通过javaCV 实现mp4转m3u8 上传oss

ffmpeg视频转切片m3u8并加密&videojs播放&hls.js播放&dplayer播放（弹幕效果）

video标签学习 & xgplayer视频播放器分段播放mp4

SpringBoot&FFmpeg实现上传视频到本地，使用M3U8切片转码后，下方使用hls.js播放（支持mp4&avi），SpringBoot + FFmpeg实现一个简单的M3U8切片转码系统

简介

将上传的视频文件，使用javacv拆分成m3u8文件和ts文件，m3u8文件和ts文件通过nginx访问，而key文件则通过web服务来获取。使用dplayer播放视频。

也可以使用ffmpeg命令来做，可以参考上面链接。

效果图

m3u8文件和ts文件通过nginx访问，而key文件则通过web服务来获取

拿不到key文件是无法播放的
