}
实体VideoInfoVO类:
package com.example.mybatisdemo02.model;import com.fasterxml.jackson.databind.ObjectMapper;
import lombok.Getter;
import lombok.Setter;@Getter
@Setter
public class VideoInfoVO {/*** 总帧数**/private int lengthInFrames;/*** 帧率**/private double frameRate;/*** 时长**/private double duration;/*** 视频编码*/private String videoCode;/*** 音频编码*/private String audioCode;private int width;private int height;private int audioChannel;private String md5;/*** 音频采样率*/private Integer sampleRate;private Double fileSize;public String toJson() {try {ObjectMapper objectMapper = new ObjectMapper();return objectMapper.writeValueAsString(this);} catch (Exception e) {return "";}}
}
调用:
public class Main {public static void main(String[] args) {VideoInfoVO videoInfoVO = FFmpegUtil.getVideoInfo("C:\\Users\\DELL\\Desktop\\test.mp4");int date = videoInfoVO.getLengthInFrames();double shichang = videoInfoVO.getDuration();System.out.println("帧数:"+date+"时长:"+shichang);}
}
结果如下图:
