spring boot Java 视频转换：avi转mp4

1.pom添加：

<dependency>
    <groupId>ws.schild</groupId>
    <artifactId>jave-core</artifactId>
    <version>3.0.1</version>
</dependency>
<dependency>
    <groupId>ws.schild</groupId>
    <artifactId>jave-nativebin-linux64</artifactId>
    <version>3.0.1</version>
</dependency>

2.新建类：

package com.api.ynlc.util;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import ws.schild.jave.*;
import ws.schild.jave.encode.AudioAttributes;
import ws.schild.jave.encode.EncodingAttributes;
import ws.schild.jave.encode.VideoAttributes;

import java.io.File;
import java.util.Date;
