jave 计算音视频时长

File source = new File("视频.mp4");
Encoder encoder = new Encoder();
try {
    MultimediaInfo info = encoder.getInfo(source);
    System.out.println("dura="+info.getDuration());
    Date date = new Date(info.getDuration());
            
    SimpleDateFormat sdf = new SimpleDateFormat("HH:mm:ss",Locale.getDefault());
    sdf.setTimeZone(TimeZone.getTimeZone("GMT"));
    System.out.println("时长="+sdf.format(date));
} catch (Exception e) {
            
}

使用新版jave

File file = new File("视频或者音频");
MultimediaObject object = new MultimediaObject(file);
//这里就是计算的时长
long duration = object.getInfo().getDuration();
