本篇内容主要讲解“怎么用Java来实现把视频批量转换为gif动态图”,感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷,实用性强。下面就让小编来带大家学习“怎么用Java来实现把视频批量转换为gif动态图”吧!
本功能实现需要用到第三方jar包 jave,JAVE 是java调用FFmpeg的封装工具。
spring boot项目pom文件中添加以下依赖
<!-- https://mvnrepository.com/artifact/ws.schild/jave-core -->
<dependency>
<groupId>ws.schild</groupId>
<artifactId>jave-core</artifactId>
<version>3.1.1</version>
</dependency>
<!-- 以下依赖根据系统二选一 -->
<!-- win系统平台的依赖 -->
<dependency>
<groupId>ws.schild</groupId>
<artifactId>jave-nativebin-win64</artifactId>
<version>3.1.1</version>
</dependency>
<!-- linux系统平台的依赖 -->
<dependency>
<groupId>ws.schild</groupId>
<artifactId>jave-nativebin-linux64</artifactId>
<version>3.1.1</version>
</dependency>
Java单类实现代码,复制到Spring boot项目中,用idea编辑器 主方法运行。
