java实现视频和配音音频的合成
音频和视屏时长一致
一、依赖
<dependency>
<groupId>org.bytedeco</groupId>
<artifactId>javacv-platform</artifactId>
<version>1.5.4</version>
</dependency>
<dependency>
<groupId>org.bytedeco</groupId>
<artifactId>javacv</artifactId>
<version>1.5.2</version>
</dependency>二、工具类
package com.xx.demo.unit;
import org.bytedeco.javacv.*;
import java.io.File;
public class MergeMovieAndVoiceUtil {
public static String mergeAudioAndVideo(String videoPath, String audioPath, String outPut) throws Exception {
#
FrameRecorder recorder = null;
FrameGrabber grabber1 = null;
FrameGrabber grabber2 = null;
try {
//抓取视频帧
grabber1 = new FFmpegFrameGrabber(videoPath);
//抓取音频帧
grabber2 = new FFmpegFrameGrabber(audioPath);
grabber1.start();
grabber2.start();
//创建录制
recorder = new FFmpegFrameRecorder(outPut,
grabber1.getImageWidth(), grabber1.getImageHeight(),
grabber2.getAudioChannels());
recorder.setFormat("mp4");
recorder.setFrameRate(grabber1.getFrameRate());
recorder.setSampleRate(grabber2.getSampleRate());
recorder.start();
Frame frame1;
Frame frame2;
//然后录入音频
while ((frame2 = grabber2.grabFrame()) != null) {
recorder.record(frame2);
}
//先录入视频
while ((frame1 = grabber1.grabFrame()) != null) {
recorder.record(frame1);
}
grabber1.stop();
grabber2.stop();
recorder.stop();
} catch (Exception e) {
e.printStackTrace();
} finally {
try {
if (recorder != null) {
recorder.release();
}
if (grabber1 != null) {
grabber1.release();
}
if (grabber2 != null) {
grabber2.release();
}
} catch (FrameRecorder.Exception e) {
e.printStackTrace();
}
}
return outPut;
}
}三、测试
@Test
void contextl() throws Exception {
String movie = "C:\\Users\\yjtzf\\Desktop\\1.mp4";
String audio = "C:\\Users\\yjtzf\\Desktop\\22.mp3";
String resultPath = "C:\\Users\\yjtzf\\Desktop\\d666.mp4";
MergeMovieAndVoiceUtil.mergeAudioAndVideo(movie, audio, resultPath);
}
