序言：书接上文，我们继续
SSM架构 +Nginx+FFmpeg实现rtsp流转hls流，在前端html上实现视频播放
步骤一：把rtsp流转化为hls流，用Java代码进行转换
java
package com.tools;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
public class RTSPtoHLS {
public static void main(String[] args) {
System.out.println("111111111111111111");
String inputVideoPath="rtsp://admin:bfm100766@192.168.1.64:554/streaming/channels/101";
String outputVideoPath ="D:/nginx/html/orb/test.m3u8";
generateVideo( inputVideoPath, outputVideoPath);
}
//视频拼接的接口
public static boolean generateVideo(String inputVideoPath, String outputVideoPath) {
try {
// 构建FFmpeg命令，这里假设是将输入视频与模板视频合成，并输出成片
// 命令示例: ffmpeg -i input.mp4 -i template.mp4 -filter_complex "your_complex_filter_graph" output.mp4
// "your_complex_filter_graph" 是你用来应用模板的复杂滤波图
// ffmpeg -fflags +genpts -i rtsp://admin:bfm100766@192.168.1.64:554/streaming/channels/101 -c copy -f hls -hls_time 2.0 -hls_list_size 1 D:/nginx/html/hls/test.m3u8
String[] command = new String[]{
"ffmpeg",
"-fflags", "+genpts",
"-i", inputVideoPath,
"-c", "copy",
"-f", "hls",
"-hls_time","10",
"-hls_list_size","10",
outputVideoPath
};
ProcessBuilder processBuilder = new ProcessBuilder(command);
Process process = processBuilder.start();
// 读取错误流并打印
BufferedReader errorReader = new BufferedReader(new InputStreamReader(process.getErrorStream()));
String line;
while ((line = errorReader.readLine()) != null) {
System.out.println(line);
}
// 等待进程结束
process.waitFor();
System.out.println("Video generation completed!!!");
return true;
} catch (IOException | InterruptedException e) {
e.printStackTrace();
System.out.println("Error generating video.");
}
return false;
}
}步骤二：SSM 架构中Controller层 如何调用
java
package com.controller;
import java.util.Calendar;
import java.util.Timer;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpSession;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import com.alibaba.fastjson.JSONObject;
import com.tools.FileCleanupTask;
import com.tools.RTSPtoHLS;
@Controller
@RequestMapping("/rh")
public class RtspHlsController {
//1跳转到前端首页面
@RequestMapping("/rh_login.html")
public String getdrLogin(HttpServletRequest request,HttpSession session)
{
return "rh_login";
}
//使用传递 参数改变全局变量的参数
@ResponseBody
@RequestMapping(value="/setHls")
public String set_Entity(HttpServletRequest request)
{
JSONObject jsonObject=new JSONObject();
//第一步先清空nginx中hls文件夹中的内容
String directoryPath = "D:/nginx/html/hls/";
long thresholdSize = 2000 * 1024; // 文件阈值大小，例如10KB
// 创建定时任务
FileCleanupTask cleanupTask = new FileCleanupTask(directoryPath, thresholdSize);
// 创建定时器并设置初始延迟为0，之后每5分钟执行一次任务（5 * 60 * 1000毫秒）
Timer timer = new Timer();
timer.schedule(cleanupTask, 60*60*1000, 60 * 60 * 1000); // 初始延迟为1000毫秒，之后每5分钟执行一次（5分钟=5*60*1000毫秒）
//第二步nginx中录入中hls文件夹中内容
//rtsp视频流的访问路径
String inputVideoPath="rtsp://admin:bfm100766@192.168.1.64:554/streaming/channels/101";
//nginx的路径 把hls视频流输入到nginx服务器 hls文件夹中下
String outputVideoPath ="D:/nginx/html/hls/test.m3u8";
RTSPtoHLS.generateVideo( inputVideoPath, outputVideoPath);
jsonObject.put("saveUrl", outputVideoPath);
return jsonObject.toString();
}
//使用传递 参数改变全局变量的参数
@ResponseBody
@RequestMapping(value="/setHls1")
public String set_Entity1(HttpServletRequest request)
{
JSONObject jsonObject=new JSONObject();
//第一步先清空nginx中hls文件夹中的内容
String directoryPath = "D:/nginx/html/hls/";
long thresholdSize = 5000 * 1024; // 文件阈值大小，例如5000KB==5M
// 创建定时任务
FileCleanupTask cleanupTask = new FileCleanupTask(directoryPath, thresholdSize);
// 创建定时器并设置初始延迟为0，之后每5分钟执行一次任务（5 * 60 * 1000毫秒）
Timer timer = new Timer();
//timer.schedule(cleanupTask, 60*60*1000, 60 * 60 * 1000); // 初始延迟为1000毫秒，之后每5分钟执行一次（5分钟=5*60*1000毫秒）
//********设置每天的12点，执行某一函数************
// 计算下一个12点的时间
Calendar calendar = Calendar.getInstance();
calendar.set(Calendar.HOUR_OF_DAY, 16); // 设置小时为12
calendar.set(Calendar.MINUTE, 40); // 设置分钟为0
calendar.set(Calendar.SECOND, 0); // 设置秒为0
calendar.set(Calendar.MILLISECOND, 0); // 设置毫秒为0
// 如果当前时间已超过今天的12点，则设置明天的12点
if (calendar.before(Calendar.getInstance())) {
calendar.add(Calendar.DATE, 1); // 明天的日期
}
// 安排任务在计算出的时间执行
timer.schedule(cleanupTask, calendar.getTime());
//第二步nginx中录入中hls文件夹中内容
//rtsp视频流的访问路径
String inputVideoPath="rtsp://admin:bfm100766@192.168.1.64:554/streaming/channels/101";
//nginx的路径 把hls视频流输入到nginx服务器 hls文件夹中下
String outputVideoPath ="D:/nginx/html/hls/test.m3u8";
RTSPtoHLS.generateVideo( inputVideoPath, outputVideoPath);
jsonObject.put("saveUrl", outputVideoPath);
return jsonObject.toString();
}
}步骤三：html播放hls流视频
