前提:1.maven工程一个  

      2.avi视频一个

第一步:

   通过pom.xml导入jave相关包

<dependency>
    <groupId>ws.schild</groupId>
    <artifactId>jave-core</artifactId>
    <version>2.4.5</version>
</dependency> 
<dependency>
    <groupId>ws.schild</groupId>
    <artifactId>jave-native-win64</artifactId>
    <version>2.4.5</version>
</dependency>

 

第二步:

  示例:

File source = new File("d://123.avi");  //源avi格式视频
File target = new File("d://456.mp4");  //转换后的mp4格式视频
AudioAttributes audio = new AudioAttributes();  
audio.setCodec("libmp3lame"); //音频编码格式 
audio.setBitRate(new Integer(64000));  
audio.setChannels(new Integer(1));  
audio.setSamplingRate(new Integer(22050));  
VideoAttributes video = new VideoAttributes();  
video.setCodec("libx264");//视频编码格式
video.setBitRate(new Integer(180000));
video.setFrameRate(new Integer(1));
EncodingAttributes attrs = new EncodingAttributes();  
attrs.setFormat("mp4");
attrs.setAudioAttributes(audio);  
attrs.setVideoAttributes(video);  
Encoder encoder = new Encoder();   
MultimediaObject multimediaObject = new MultimediaObject(source);
encoder.encode(multimediaObject, target, attrs);//转换开始。。。
