一、创建SpringBoot工程

SpringBoot调用FFmpeg推流到SRS服务器_SpringBoot

二、引入依赖

  <!--hutool-->
        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
            <version>5.7.11</version>
        </dependency>

三、application.yml配置

srs:
  # 目标地址
  targetAddress: rtmp://localhost/live/livestream
  resources:
    # ffmpeg目录名
    ffmpegPath: ffmpeg

四、集成ffmpeg工具

在resources目录下新建ffmpeg文件夹，并且创建win文件夹，把ffmpeg.exe等工具放到里面。

五、编写推流代码

package com.example.ffmpeg.util;

import cn.hutool.core.io.resource.ClassPathResource;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.ApplicationArguments;
import org.springframework.boot.ApplicationRunner;
import org.springframework.stereotype.Component;

import java.io.BufferedReader;
import java.io.File;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.concurrent.ArrayBlockingQueue;
import java.util.concurrent.Executors;
import java.util.concurrent.ThreadPoolExecutor;
import java.util.concurrent.TimeUnit;

/**

@Component
public class PushCameraStreamByFFmpeg implements ApplicationRunner {


    @Value("${srs.targetAddress}")
    private String targetAddress;

    @Value("${srs.resources.ffmpegPath}")
    private String ffmpegPath;

    ThreadPoolExecutor threadPool = new ThreadPoolExecutor(2, 5, 60, TimeUnit.SECONDS, new ArrayBlockingQueue<>(3), Executors.defaultThreadFactory(), new ThreadPoolExecutor.DiscardPolicy());

    /**
     * springboot容器启动之后执行
     *
     * @param args
     * @throws Exception
     */
    @Override
    public void run(ApplicationArguments args) {
        threadPool.execute(() -> {
            startPushCameraStream(targetAddress);
        });
    }

    /**

     * 播放地址 http://localhost:8080/live/livestream.flv
     *
     * @param targetAddress SRS地址   rtmp://localhost/live/livestream
     */
    public void startPushCameraStream(String targetAddress) {
        try {
            String path = getFFmpegPath();
            // 视频来源于绝对路径 E:\m4a\source.flv
            String command = path + "ffmpeg -re -i E:\\m4a\\source.flv -c copy -f flv " + targetAddress;
            Process process = Runtime.getRuntime().exec(command);
            BufferedReader br = new BufferedReader(new InputStreamReader(process.getErrorStream()));
            String line = null;
            while ((line = br.readLine()) != null) {
                System.out.println("视频推流信息[" + line + "]");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

    /**
     * 获取ffmpeg.exe的路径
     *
     * @return
     */
    private String getFFmpegPath() throws IOException {
        String os = null;
        String osName = System.getProperties().getProperty("os.name");
        System.out.println("current system :" + osName);
        if (osName.contains("Windows")) {
            os = "win";
        } else if (osName.contains("Linux")) {
            os = "linux";
        } else {
            throw new RuntimeException("This operating system is not supported!");
        }
        if (os == null) {
            throw new RuntimeException("ffmpeg.exe path not found!");
        }

        ClassPathResource classPathResource = new ClassPathResource(ffmpegPath + File.separator + os + File.separator);
        return classPathResource.getAbsolutePath();
    }
}

六、启动SRS服务器和启动应用程序

启动SRS服务，我们上一张节已经实现。https://blog.51cto.com/u_13312531/6675258

SpringBoot调用FFmpeg推流到SRS服务器_SpringBoot_03

然后我们在SRS里使用播放器播放。
