java 使用ffmpeg压缩视频

1.在linux下使用的话，需要导入jave包

jar包地址

//java代码
private boolean ffmpegChange1 (File file,File fileSave){
        try{
            AudioAttributes audio = new AudioAttributes();
            audio.setCodec("libmp3lame");
            audio.setBitRate(new Integer(56000));
            audio.setChannels(new Integer(1));
            audio.setSamplingRate(new Integer(22050));

            VideoAttributes video = new VideoAttributes();
           // video.setCodec(myConfig.getFileFFmpegPath());
//            video.setCodec("libx264");
           video.setCodec("mpeg4");
          // video.setCodec("h264");
            video.setBitRate(new Integer(800000));
            video.setFrameRate(new Integer(15));

            EncodingAttributes attrs = new EncodingAttributes();
            attrs.setFormat("mp4");
            attrs.setAudioAttributes(audio);
            attrs.setVideoAttributes(video);

            Encoder encoder = new Encoder();

            long beginTime = System.currentTimeMillis();
            MultimediaInfo m = encoder.getInfo(file);
            System.out.println(m.getDuration()/1000 + "秒");
            System.out.println("获取时长花费时间是：" + ((System.currentTimeMillis() - beginTime))/1000 + "秒");
            beginTime = System.currentTimeMillis();
//            encoder.encode(source, fileSave, attrs);

            encoder.encode(file, fileSave, attrs);
//            System.out.println("压缩完成...");
            System.out.println("压缩完成花费时间是：" + ((System.currentTimeMillis() - beginTime))/1000 + "秒");
            return true;
        }catch (EncoderException e){
            e.printStackTrace();
            System.out.println("压缩错误信息是1："+e.getMessage());
            return false;
        }
    }
//pom文件引用
   
            java
            jave
            1.0.2.
            system
            ${project.basedir}/src/main/resources/lib/jave-1.0.2.jar
        

2.在Mac上跑

jar包地址
ffmpeg地址

    private boolean ffmpegChange (File file,File fileSave){
        try{
            AudioAttributes audio = new AudioAttributes();
            audio.setCodec("libmp3lame");
            audio.setBitRate(new Integer(56000));
            audio.setChannels(new Integer(1));
            audio.setSamplingRate(new Integer(22050));

            VideoAttributes video = new VideoAttributes();
            //video.setCodec("mpeg4");
            video.setCodec("h264");
            video.setBitRate(new Integer(800000));
            video.setFrameRate(new Integer(1));

            EncodingAttributes attrs = new EncodingAttributes();
            attrs.setFormat("mp4");
            attrs.setAudioAttributes(audio);
            attrs.setVideoAttributes(video);

            Encoder encoder = new Encoder(new MyFFMPEGExecute());

            long beginTime = System.currentTimeMillis();
            MultimediaInfo m = encoder.getInfo(file);
            System.out.println(m.getDuration()/1000 + "秒");
            System.out.println("获取时长花费时间是：" + ((System.currentTimeMillis() - beginTime))/1000 + "秒");
            beginTime = System.currentTimeMillis();
//            encoder.encode(source, fileSave, attrs);

            encoder.encode(file, fileSave, attrs);
//            System.out.println("压缩完成...");
            System.out.println("压缩完成花费时间是：" + ((System.currentTimeMillis() - beginTime))/1000 + "秒");
            return true;
        }catch (EncoderException e){
            e.printStackTrace();
            System.out.println("压缩错误信息是："+e.getMessage());
            return false;
        }
    }
//重写ffmpeg地址，path我用的是绝对路径，获取ffmpeg
public class MyFFMPEGExecute extends FFMPEGLocator {
    @Autowired
    MyConfig myConfig;
 @Override
    protected String getFFMPEGExecutablePath() {
        String path1 = "/Users/apple/Desktop/imagecollect/file/ffmpeg";
        String path2 = "/root/imagecollect/ffmpeg";
//        System.out.println("ffmpegways = " + path);
        return path1;
    }
}

//pom文件引用
      
            java
            jave
            2.0
            system
            ${project.basedir}/src/main/resources/lib/jave-2.0.jar
        

3.在linux中跑 用jave.2.0.jar的方法,代码同上，唯一区别是ffmpeg的执行包不同

ffmpeg地址

//重写ffmpeg地址，path我用的是绝对路径，获取ffmpeg
public class MyFFMPEGExecute extends FFMPEGLocator {
    @Autowired
    MyConfig myConfig;
 @Override
    protected String getFFMPEGExecutablePath() {
        String path1 = "/Users/apple/Desktop/imagecollect/file/ffmpeg";
        String path2 = "/root/imagecollect/ffmpeg";
//此处用path2，此路径是服务器上绝对路径，记得把ffmpeg放到此路径位置就可以
        return path2;
    }
}
