} 3、cmd 到nginx根目录启动nginx
nginx.exe -c conf\nginx-win-rtmp.conf
测试：浏览器输入 http://localhost:5080/stat，看到
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。
 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
 6、测试ffmpeg
cmd ffmpeg -version 命令看到代表成功
 7、下载VLC播放器
下载地址： https://www.videolan.org/vlc/
 8、查摄像头的rtsp协议格式
我这里截图是海康威视的
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
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
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
 11、测试是否成功
等待几秒钟看到有视频播放就是成功了
 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hls1、nginx配置：
在前面已经贴出来了，其中这几个是针对hls的
 2、执行ffmepg命令
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 3、查看nginx根目录 -> hls -> test.m3u8 是否生成
生成了代表一切正常
 4、m3u8在网页上播放
<!DOCTYPE html>
<html lang="zh-CN">
<head>
<meta charset="UTF-8">
<title>前端播放m3u8格式视频</title>
<!--https://www.bootcdn.cn/video.js/-->
<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>
<!--https://www.bootcdn.cn/videojs-contrib-hls/-->
<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>
source标签的src属性： http://你的nginx ip:nginx http端口/hls/test.m3u8
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
#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
m3u8文件它不是视频源，源头是ts后缀文件
 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
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;
}
}
}
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';
} 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
@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);
}
} 4、执行ffmepg命令：
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" 4.1 采用java代码去执行ffmepg命令
依赖 javaCV
<dependency>
<groupId>org.bytedeco</groupId>
<artifactId>javacv-platform</artifactId>
<version>1.5.2</version>
</dependency>
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();
}
} 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：
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>播放http-flv</title>
</head>
<body>
<video id="videoElement"></video>
<script src="https://cdn.bootcdn.net/ajax/libs/flv.js/1.6.2/flv.min.js"></script>
<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> 7、大功告成
