目地:写一个java制作视频的网站。
大致流程:用户上传n张图片和背景音乐,网站返回一个视频。
大家都知道,java是通过命令行来调用ffmpeg的,java没有现成的比较好的封装ffmpeg的jar包。
所以,我们需要自己写调用ffmpeg的接口。
我采用的是spring boot架构。
首先配置pom文件
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>

<dependency>

<version>2.3.1</version>
</dependency>
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
</dependency>
</dependencies>
注意:整个项目全部依赖此pom文件,后面不再更改。
我们还需要一个命令行处理器,创建一个CmdExecuter
package com.example.demo.util;
import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.util.LinkedList;
import java.util.List;
public class CmdExecuter {
public static String exec(List<String> cmd) {
String converted_time = null;
Process proc =null;
BufferedReader stdout = null;
try {
ProcessBuilder builder = new ProcessBuilder();
builder.command(cmd);
builder.redirectErrorStream(true);
proc = builder.start();
stdout = new BufferedReader(new InputStreamReader(proc.getInputStream()));
String line;
int lineNumber=1;
List<String> returnStringList = new LinkedList<String>();
// 命令行信息
for(String attribute : cmd) {
System.out.println(attribute);
}
// 命令行调试信息
while ((line = stdout.readLine()) != null) {
System.out.println("第"+lineNumber+"行:"+line);
lineNumber=lineNumber+1;
returnStringList.add(FFMPEG.dealString(line));
}
String info = "";
for (int i = returnStringList.size() - 1; i >= 0; i--) {
if (null != returnStringList.get(i) && returnStringList.get(i).startsWith("frame=")) {
info = returnStringList.get(i);
break;
}
}
if (null != info) {
converted_time = info.split("time=")[1].split("bitrate=")[0].trim();
}
} catch (IndexOutOfBoundsException ex) {
converted_time = null;
} catch (Exception e) {
e.printStackTrace();
}finally{
try {
proc.waitFor();
stdout.close();
} catch (Exception e) {
e.printStackTrace();
}
}
return converted_time;
}
}
随后我们需要一个配置地址的类PropertyPlaceholder
package com.example.demo.entity;
import org.springframework.stereotype.Component;
/**
* @program: javavc
* @author: wlr
* @create: 2019-07-26 10:20
* @description:
**/
@Component
//@ConfigurationProperties(prefix = "person")
public class PropertyPlaceholder {
// 根目录
static String rootdir=System.getProperty("user.dir");
// ffmpeg路径
private String ffmpegpath="\\src\\main\\java\\com\\example\\demo\\tool\\bin\\ffmpeg.exe";
// 图片输入目录
private String pictureInput="\\src\\main\\resources\\picture\\input";
// 图片输出目录
private String pictureOut="\\src\\main\\resources\\picture\\out";
// 视频输入目录
private String mp4Input="\\src\\main\\resources\\mp4\\input";
// 视频输出目录
private String mp4Out="\\src\\main\\resources\\mp4\\out";
// private String videoPath=mp4Input;
// private String videoFramesPath=mp4Out;
public static String getRootdir() {
return rootdir;
}
public String getFfmpegpath() {
return rootdir+ffmpegpath;
}
public void setFfmpegpath(String ffmpegpath) {
this.ffmpegpath = ffmpegpath;
}
public String getPictureInput() {
return rootdir+pictureInput;
}
public void setPictureInput(String pictureInput) {
this.pictureInput = pictureInput;
}
public String getPictureOut() {
return rootdir+pictureOut;
}
public void setPictureOut(String pictureOut) {
this.pictureOut = pictureOut;
}
public String getMp4Input() {
return rootdir+mp4Input;
}
public void setMp4Input(String mp4Input) {
this.mp4Input = mp4Input;
}
public String getMp4Out() {
return rootdir+mp4Out;
}
public void setMp4Out(String mp4Out) {
this.mp4Out = mp4Out;
}
// public String getVideoPath() {
// return rootdir+videoPath;
// }
//
// public void setVideoPath(String videoPath) {
// this.videoPath = videoPath;
// }
//
// public String getVideoFramesPath() {
// return rootdir+videoFramesPath;
// }
//
// public void setVideoFramesPath(String videoFramesPath) {
// this.videoFramesPath = videoFramesPath;
// }
public String getPictureOut(String img_path) {
return rootdir+pictureOut+"\\"+img_path;
}
}
接下来我们需要在PropertyPlaceholder类指向ffmpeg的地址放放置ffmpeg的解压版

最后,通过VideoController调用MarkText4J
package com.example.demo.controller;
import com.example.demo.service.impl.MarkText4J;
//import com.example.demo.util.VideoProcessing;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.util.ArrayList;
import java.util.Queue;
@RestController
public class VideoController {
@Autowired
MarkText4J mark;
// 将视频用图片的形式保存
// @RequestMapping(value = "/grabberVideoFrame")
// public void grabberVideoFrame(String videoFileName){
// videoProcessing.grabberVideoFramer(videoFileName);
// }
// 将图片生成视频
@RequestMapping(value = "/makeVideo")
public void makeVideo(){
ArrayList<String> filename = new ArrayList<>();
filename.add("1.png");
filename.add("2.png");
filename.add("3.png");
filename.add("4.png");
filename.add("culture.mp3");
mark.makePictureInDirByGotravale("www",filename);
}
}
以下是我的文件放置方式,方便大家实现demo
,
application.properties

spring.servlet.multipart.max-file-size=10MB
spring.servlet.multipart.max-request-size=100MB
spring.servlet.multipart.resolve-lazily=false
spring.mvc.view.prefix=/
spring.mvc.view.suffix=.jsp
spring.jpa.open-in-view=false
application.yml
spring:
#配置属性文件

# validate 项目启动表结构进行校验 如果不一致则报错
ddl-auto: update
#改属性值若为true,操作数据库时,可打印SQL语句到控制台
show-sql: true
由于图片,视频等资源过大,我将其上传到我的博客中大家可以自行下载。目前在intel i7 7700的cpu下需要40秒左右生成一个4.76MB的视频,项目算法正在优化中。
在下一篇文章中,将会阐述视频制作逻辑
