    • 4.1 采用java代码去执行ffmepg命令
    • 6、前端使用flv.js播放：

需求背景：

在做之前的项目的时候有一个对接摄像头实时播放的需求，由于我们摄像头的购买量不是很多，海康威视不给我们提供流媒体云服务器，所以需要我们自己去 一个去满足我们能在浏览器看到监控画面。项目源代码在以前公司没有拷贝就不能复习，最近又在准备面试，所以写了这个博客来复盘和扩展一下，由于我现在没有Liunx，我就用Windows来演示，生产环境还是要使用Liunx，下面这些操作在Liunx也是一样的流程，大家自行百度。

一：了解音视频流协议：

<caption>媒体流协议对比</caption>

FLV TAG

| TS文件 |

Mp4

3gp

webm

|
| 原理 |

同 RTMP ，使用HTTP协议（80端口）

|

每个时刻的数据收到后立刻转发

|

集合一段时间的数据，生成TS切片文件（三片），并更新m3u8索引

| |
| 延时 |

低

1~3秒

|

低

1~3秒

|

高

5~20秒（依切片情况）

| 高 |
| 数据分段 | 连续流 | 连续流 | 切片文件 | 切片文件 |
| Html5播放 |

可通过HTML5解封包播放

（flv.js）

| 不支持 |

可通过HTML5解封包播放

（hls.js）

|

如果dash文件列表是MP4，

webm文件，可直接播放

|
| 其它 |

需要Flash技术支持，不支持多音频流、多视频流，不便于seek（即拖进度条）

|

跨平台支持较差，需要Flash技术支持

|

播放时需要多次请求，对于网络质量要求高

| |

二：方案一 rtsp 转rtmp

1、下载nginx + nginx-rtmp-module

nginx：下载地址： http://nginx-win.ecsds.eu/download/

nginx-rtmp-module：nginx 的扩展，安装后支持rtmp协议，下载地址： https://github.com/arut/nginx-rtmp-module

解压nginx-rtmp-module到nginx根目录下，并修改其文件夹名为nginx-rtmp-module（原名为nginx-rtmp-module-master）

2、nginx配置文件

到nginx根目录下的conf目录下复制一份nginx-win.conf 重命名 nginx-win-rtmp.conf

nginx-win-rtmp.conf：

<pre class="prettyprint hljs cmake" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">#user nobody;

3、cmd 到nginx根目录启动nginx

<pre class="hljs vim" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 0.75em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">nginx.exe -c conf\nginx-win-rtmp.conf</pre>

测试：浏览器输入 http://localhost:5080/stat，看到

image.png

代表安装成功

4、下载ffmpeg安装

ffmpeg：一个处理音视频强大的库，我们需要用它来转协议，下载地址： https://www.gyan.dev/ffmpeg/builds/ ，这里可以下载essential和full版本，essential就是简版，只包含ffmpeg.exe、ffplay.exe、

ffprobe.exe， 而full版本就包含了动态库和相关头文件，方便我们在开发中调用。

image.png

5、配置ffmpeg环境变量

将ffmpeg解压后里面的bin路径复制到Path里面去

image.png

6、测试ffmpeg

cmd ffmpeg -version 命令看到代表成功

image.png

7、下载VLC播放器

下载地址： https://www.videolan.org/vlc/

image.png

8、查摄像头的rtsp协议格式

我这里截图是海康威视的

image.png

image.png

现在没有测试的流，我找了个点播的rtsp

rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mp4，用这个代替是一样的

9、执行ffmpeg命令

ffmpeg强大，命令也是复杂，我们cmd 执行

<pre class="prettyprint hljs groovy" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">ffmpeg -re -rtsp_transport tcp -stimeout 20000000 -i "rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mp4" -buffer_size 1024000 -max_delay 500000 -codec:v libx264 -r 25 -rtbufsize 10M -s 1280x720 -map:v 0 -an -f flv rtmp://127.0.0.1:1935/live/test</pre>

rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mp4，是输入源头

rtmp://127.0.0.1:1935/live/test 是输出地址

如果没有报错的话，到现在rtsp就已经转换好了

ffmpeg命令学习： https://www.jianshu.com/p/df3216a52e59 、 https://blog.csdn.net/fuhanghang/article/details/123565920

10、测试rtmp是否转换成功

我们打开VLC，媒体->打开网络串流->输入 rtmp://127.0.0.1:1935/live/test -> 播放

image.png

11、测试是否成功

等待几秒钟看到有视频播放就是成功了

image.png

12、为什么放弃了用rtmp

rtmp的优点是延迟低，效率高，但是在浏览器需要安装flash才能放，也就老版本的浏览器在用，rtmp可能会在别的地方支持，所以还是把他方式方法贴出来了。

三：方案二 rtsp转hls

1、nginx配置：

在前面已经贴出来了，其中这几个是针对hls的

image.png

image.png

2、执行ffmepg命令

<pre class="prettyprint hljs awk" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">ffmpeg -i "rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mp4" -vcodec libx264 -acodec aac -f flv rtmp://127.0.0.1:1935/hls/test</pre>

3、查看nginx根目录 -> hls -> test.m3u8 是否生成

生成了代表一切正常

image.png

4、m3u8在网页上播放

<pre class="prettyprint hljs xml" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="UTF-8">
<title>前端播放m3u8格式视频</title>

<link href="https://cdn.bootcss.com/video.js/7.6.5/alt/video-js-cdn.min.css" rel="stylesheet">
<script src="https://cdn.bootcss.com/video.js/6.6.2/video.js"></script>

<script src="https://cdn.bootcss.com/videojs-contrib-hls/5.15.0/videojs-contrib-hls.min.js"></script>
</head>
<body>
<video id="myVideo" class="video-js vjs-default-skin vjs-big-play-centered" controls preload="auto" width="1080" height="708" data-setup='{}'>
<source id="source" src="http://127.0.0.1:5080/hls/test.m3u8" type="application/x-mpegURL">
</video>
</body>
<script> // videojs 简单使用
var myVideo = videojs('myVideo',{
bigPlayButton : true,
textTrackDisplay : false,
posterImage: false,
errorDisplay : false,
})
myVideo.play() // 视频播放
myVideo.pause() // 视频暂停 </script>
</html></pre>

source标签的src属性： http://你的nginx ip:nginx http端口/hls/test.m3u8

image.png

rtsp转HLS成功！

5、认识一下m3u8格式

m3u8文件里面存储了一个索引，以文本格式打开是这样的

<pre class="prettyprint hljs css" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">#EXTM3U

EXT-X-VERSION:3

EXT-X-MEDIA-SEQUENCE:56

EXT-X-TARGETDURATION:13

EXTINF:10.381,

test-56.ts

EXTINF:10.422,

test-57.ts

EXTINF:13.453,

test-58.ts</pre>

m3u8文件它不是视频源，源头是ts后缀文件

image.png

6、为什么放弃了用HLS

转HLS协议及网页加载过程：

ffmepg收到rtsp的流时候，会等一个切片的时间，一个切片时间到了，切片ts会放到服务器中，同时m3u8文件中加一个索引，对应着新进入的切片。网页在加载m3u8的时候，就是读取m3u8中的的索引去加载ts文件，所以在不断的请求ts，对ts进行解析，不断的和TCP握手，这就是为什么HLS延迟高和对网速的要求高的原因，我们监控肯定是要延迟低的，HLS兼容性好，适合点播。

四：方案三rtsp 转httpflv(采用)

1、安装nginx-flv-module

这个插件需要编译，教程： https://blog.csdn.net/KayChanGEEK/article/details/105095844

我这里已经编译好了，直接下载启动：

https://gitee.com/isyuesen/nginx-flv-file

2、nginx配置

看我git里面的https://gitee.com/isyuesen/nginx-flv-file/blob/master/conf/nginx.conf，和默认的config差别主要是添加了这几个

<pre class="prettyprint hljs nginx" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">rtmp {
server {
listen 1935;
# 流复用的最大块大小
chunk_size 4000;
application liveapp {
live on;
# 推流开始
on_publish http://localhost:8081/auth;
# 推流关闭
on_publish_done http://localhost:8081/auth;
# 客户端开始播放
on_play http://localhost:8081/auth;
# 客户端结束播放
on_play_done http://localhost:8081/auth;
}
}
}</pre>

<pre class="prettyprint hljs nginx" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">location /live {
flv_live on;
chunked_transfer_encoding on;
add_header 'Access-Control-Allow-Credentials' 'true'; #add additional HTTP header
add_header 'Access-Control-Allow-Origin' '*'; #add additional HTTP header
add_header Access-Control-Allow-Headers X-Requested-With;
add_header Access-Control-Allow-Methods GET,POST,OPTIONS;
add_header 'Cache-Control' 'no-cache';
}</pre>

3、做java权限认证

nginx rtmp配置中有配置on_publish钩子接口 http://localhost:8081/auth，这个回调HttpResponse stausCode如果不等于200会拒绝I/O，更多回调钩子看： https://github.com/arut/nginx-rtmp-module/wiki/Directives#on_connect

<pre class="prettyprint hljs java" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">@PostMapping("/auth")
public void getVideo(String token, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
if (token.equals("tokenValue")) {
httpServletResponse.setStatus(200);
} else {
// 拒绝服务
httpServletResponse.setStatus(500);
}
}</pre>

4、执行ffmepg命令：

<pre class="prettyprint hljs bash" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">ffmpeg -re -rtsp_transport tcp -i "rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mp4" -f flv -vcodec h264 -vprofile baseline -acodec aac -ar 44100 -strict -2 -ac 1 -f flv -s 640*360 -q 10 "rtmp://127.0.0.1:1935/liveapp/test"</pre>

4.1 采用java代码去执行ffmepg命令

依赖 javaCV

<pre class="prettyprint hljs xml" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><dependency>
<groupId>org.bytedeco</groupId>
<artifactId>javacv-platform</artifactId>
<version>1.5.2</version>
</dependency></pre>

<pre class="prettyprint hljs dart" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;">public class App {
public static void main( String[] args ) throws IOException, InterruptedException {
String name = "test";
// rtsp地址
String rtspDir = "rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mp4";
// rtmp地址
String rtmpDir = "rtmp://192.168.0.140:1935/liveapp/" + name + "?token=tokenValue";

    String ffmpeg = Loader.load(org.bytedeco.ffmpeg.ffmpeg.class);
    ProcessBuilder pb = new ProcessBuilder(ffmpeg,
            "-re",
            "-rtsp_transport",
            "tcp",
            "-i",
            rtspDir,
            "-f",
            "flv",
            "-vcodec",
            "h264",
            "-vprofile",
            "baseline",
            "-acodec",
            "aac",
            "-ar",
            "44100",
            "-strict",
            "-2",
            "-ac",
            "1",
            "-f",
            "flv",
            "-s",
            "640*360",
            "-q",
            "10",
            rtmpDir
    );
    pb.inheritIO().start().waitFor();
}

}</pre>

5、测试http-flv链接

如果你跟着我做的，那链接就是 http://127.0.0.1:18080/live?port=1935&app=liveapp&stream=test&token=tokenValue，在VLC播放器中点击媒体 -> 打开网络串流 -> 输入http://127.0.0.1:18080/live?port=1935&app=liveapp&stream=test&token=tokenValue -> 播放

有视频证明你离成功就差最后一步

6、前端使用flv.js播放：

<pre class="prettyprint hljs xml" style="padding: 0.5em; font-family: Menlo, Monaco, Consolas, "Courier New", monospace; color: rgb(68, 68, 68); border-radius: 4px; display: block; margin: 0px 0px 1.5em; font-size: 14px; line-height: 1.5em; word-break: break-all; word-wrap: break-word; white-space: pre; background-color: rgb(246, 246, 246); border: none; overflow-x: auto; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial;"><!doctype html>

<script> if (flvjs.isSupported()) {
const videoElement = document.getElementById('videoElement');
const flvPlayer = flvjs.createPlayer({
type: 'flv',
url: 'http://127.0.0.1:18080/live?port=1935&app=liveapp&stream=test&token=tokenValue'
});
flvPlayer.attachMediaElement(videoElement);
flvPlayer.load();
flvPlayer.play();
} </script>
</body>
</html></pre>

7、大功告成
