JAVA无需本地下载Ffmpeg，实现FfmpegCMD
本文不须要本地下载Ffmpeg，只需引入maven依赖即可
1、增加maven依赖
<!--m3u8视频转码须要FFmpeg依赖--> <dependency> <groupId>ws.schild</groupId> <artifactId>jave-all-deps</artifactId> <version>3.3.1</version> </dependency> <dependency> <groupId>ws.schild</groupId> <artifactId>jave-core</artifactId> <version>3.3.1</version> </dependency> <dependency> <groupId>ws.schild</groupId> <artifactId>jave-nativebin-win64</artifactId> <version>3.3.1</version> </dependency>2、编写代码
