1.首先下载ffmpeg和ffplay

1.1下载 Nginx

进入Nginx下载页面（ http://nginx-win.ecsds.eu/download/ ），选择合适的版本下载。这里以 nginx 1.7.11.3 Gryphon 为例。下载完成后解压，将解压后的目录重命名为“ nginx-1.7.11.3-Gryphon ”，并放到合适的路径下。

1.2下载服务器状态检查程序 stat.xsl

下载地址： https://github.com/arut/nginx-rtmp-module/ 将nginx-rtmp-module-master.zip解压后复制到目录:nginx-1.7.11.3-Gryphon下，

保证stat.xls的目录为:

nginx-1.7.11.3-Gryphon\nginx-rtmp-module\stat.xsl

1.3创建配置文件 conf\nginx-win-rtmp.conf

在目录 nginx-1.7.11.3-Gryphon\conf下创建 nginx-win-rtmp.conf配置文件，内容如下：

# multiple workers works !
worker_processes  2;
 
#error_log  logs/error.log;

1.4启动Nginx服务器

cd nginx-1.7.11.3-Gryphon
nginx.exe -c conf\nginx-win-rtmp.conf

2.ffmpeg查看电脑设备

ffmpeg -list_devices true -f dshow -i dummy

NGINX推流延迟大 nginx拉流_NGINX推流延迟大_03

可以看到我电脑里面有Integrated Camera摄像头和一个乱码的麦克风

如果设备名称有中文，会出现乱码，想看设备原名，可以去设备管理器中查看，又可以利用第三方工具查看，推荐后者。

比如使用graphedit，打开程序后图表-> 插入过滤器，就可以看到相应的设备名

可以发现可用设备为Integrated Camera和麦克风 (2- USB2.0 MIC)

3.测试摄像头是否可用

ffplay -f dshow -i video="Integrated Camera"

或者

ffplay -f vfwcap -i 0

如果成功弹出播放窗口，则代表设备可用，否则可能是设备不可用或者设备被占用

4.查看摄像头和麦克风信息

ffmpeg -list_options true -f dshow -i video="Integrated Camera"

ffmpeg -list_options true -f dshow -i audio="麦克风 (2- USB2.0 MIC)"

5.本地视频的推流

先进行简单的本地视频推流模拟，我们在ffmpeg的目录下放置一个视频，然后cmd进入该目录，把视频推流至rtmp://localhost:1935/live/home ，localhost:1935为rtmp服务器地址、live为nginx配置节点、home当做密钥，推流拉流地址一样即可播放。语句如下：

ffmpeg -re -i 1.mp4 -f flv rtmp://localhost:1935/live/home

或者

ffmpeg -re -i aa.mp4 -vcodec libx264 -acodec aac -f flv rtmp://localhost:1935/live/home

6.拉流验证

6.1 使用ffplay进行拉流

ffplay -fs rtmp://localhost:1935/live/home

6.2 使用VLC进行拉流

打开VLC，选择【媒体】 -> 【打开网络串流】，输入 rtmp://localhost:1935/live/home ，点击【播放】就可以看到流了。

7.摄像头推流

接下来正式把对摄像头进行推流，从前面我们知道摄像头名称为Integrated Camera，而且推流服务器ip为localhost:1935，关键字为live，所以cmd中输入以下语句：

ffmpeg -f dshow -i video="Integrated Camera" -vcodec libx264 -preset:v ultrafast -tune:v zerolatency -f flv rtmp://localhost:1935/live/home

拉流验证同上。

8.麦克风推流

ffmpeg -f dshow -i audio="麦克风 (2- USB2.0 MIC)" -vcodec libx264 -preset:v ultrafast -tune:v zerolatency -f flv rtmp://localhost:1935/live/home

9.摄像头&麦克风推流

ffmpeg -f dshow -i video="USB2.0 PC CAMERA" -f dshow -i audio="麦克风 (2- USB2.0 MIC)" -vcodec libx264 -preset:v ultrafast -tune:v zerolatency -f flv rtmp://localhost:1935/live/home

或者

ffmpeg -f dshow -i video="USB2.0 PC CAMERA":audio="麦克风 (2- USB2.0 MIC)" -vcodec libx264 -r 25 -preset:v ultrafast -tune:v zerolatency -f flv rtmp://localhost:1935/live/home
