本文主要介绍了Java用20行代码实现抖音小视频批量转换为gif动态图，分享给大家，具体如下：

效果图

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。
