java 获取视频的时长

用到的类库为：jave-1.0.2.jar

                    /** * 获取视频文件播放时长 * @param src * @return 返回毫秒值 */public static long getVideoLength(String src){File file=new File(src);MultimediaInfo multimediaInfo;Encoder encoder=new Encoder();try{multimediaInfo=encoder.getInfo(file);VideoInfo videoInfo= multimediaInfo.getVideo();videoInfo.getDecoder();multimediaInfo.getFormat();return multimediaInfo.getDuration();}catch (Exception e){e.printStackTrace();}return 0;}        /** * 获取文件播放时长 * @param fileName * @return HH:mm:ss 格式字符串 */public static String getVideoLengthStr(String fileName){long length= getVideoLength(fileName);//小时int h=(int)length/(60*60*1000);int m=(int)(length%(60*60*1000))/(60*1000);int s=(int)(length%(60*1000))/(1000);StringBuilder sb=new StringBuilder();if (h<10){sb.append("0").append(h);}else {sb.append(h);}sb.append(":");if (m<10){sb.append("0").append(m);}else {sb.append(m);}sb.append(":");if (s<10){sb.append("0").append(s);}else {sb.append(s);}return sb.toString();}
