Java将视频文件avi/rmvb等格式转换成mp4_java avi视频转码mp4

目前已验证支持avi,flv,mpg,mpeg,mov,rmvb,asf,ogv等视频文件格式转成mp4，至于mp4转成其他类型，目前只验证了一种mp4->mov, 感兴趣的小伙伴可以验证下mp4转成其他类型。

首先引入maven依赖

        <dependency>
			<groupId>org.bytedeco</groupId>
			<artifactId>javacv</artifactId>
			<version>1.5.10</version>
		</dependency>
 
		<dependency>
			<groupId>org.bytedeco</groupId>
			<artifactId>javacv-platform</artifactId>
			<version>1.5.10</version>
		</dependency>

工具类和main方法：

package com.person.ai.config;
 
 
import lombok.extern.slf4j.Slf4j;
import org.bytedeco.javacv.*;
 
@Slf4j
public class CovertVideoUtils {
 
    /**
     *
     * @param inputPath 源文件
     * @param outputPath 目标文件
     * @param format 生成目标文件的格式
     * @throws FrameRecorder.Exception 异常类
     */
    public static void convert(String inputPath, String outputPath, String format) throws FrameRecorder.Exception {
       try {
           FFmpegFrameGrabber frameGrabber = new FFmpegFrameGrabber(inputPath);
           frameGrabber.start();
 
           FFmpegFrameRecorder frameRecorder = new FFmpegFrameRecorder(outputPath, frameGrabber.getImageWidth(), frameGrabber.getImageHeight(), frameGrabber.getAudioChannels());
           frameRecorder.setFormat(format);
           frameRecorder.setFrameRate(frameGrabber.getFrameRate());
           frameRecorder.setSampleRate(frameGrabber.getSampleRate());
           frameRecorder.start();
 
           Frame frame;
           while ((frame = frameGrabber.grabFrame()) != null) {
               frameRecorder.record(frame);
           }
 
           frameRecorder.stop();
           frameGrabber.stop();
       }
       catch (FrameGrabber.Exception e) {
           log.error("convert failed", e);
       }
    }
 
 
    public static void main(String[] args) throws FrameRecorder.Exception {
        CovertVideoUtils.convert("E:/video/output4.mp4", "E:/video/output6.mov", "mov");
    }
}
