ffmpeg+nginx建立rtmp服务器，播放摄像头流
好文章，http://blog.fs-linux.org/?p=137
先转载，然后再动手实践看看
live555可以建立rtsp这个大伙都知道，ffserver+ffmpeg也可以建立一个实时rtsp服务，那么rtmp呢？好多人会首选red5，al'right，这里用的是nginx，下面记录一下使用nginx建立rtmp的全过程
首先下载一份nginx的rtmp的module
|
1
|
git clone https:
//github.com/arut/nginx-rtmp-module.git
|
下载好nginx-rtmp-module以后，需要将ginx-rtmp编译进nginx
|
1
2
3
4
|
cd nginx
./configure --prefix=/usr/local/nginx/ --add-module=/root/nginx-rtmp-module --with-http_ssl_module
make
make install
|
这样，就将nginx-rtmp-module编译进nginx里面,并安装到/usr/local/nginx里面了
接下来配置一下nginx的配置文件既可
在nginx-rtmp-module中可以看到nginx配置文件的参考

当然，如果只为了测试rtmp，完全可以将test中的rtmp放在/usr/local/nginx/conf/中,记得要备份/usr/local/nginx/conf下的nginx.conf
将nginx.conf中的内容修改如下：

}
rtmp {
server {
listen 1935;
application myapp {
live on;
}
}
}
http {
server {
listen 80;
location /stat {
rtmp_stat all;
rtmp_stat_stylesheet stat.xsl;
}
location /stat.xsl {
root /usr/local/nginx/html/nginx-rtmp-module/;
}
location /control {
rtmp_control all;
}
location /rtmp-publisher {
root /usr/local/nginx/html/nginx-rtmp-module/test;
}
location / {
root /usr/local/nginx/html/nginx-rtmp-module/test/www;
}
}
}
|
配置完成之后，可以启动nginx
|
1
|
/usr/local/nginx/sbin/nginx
|
nginx从此启动完成
接下来试一下
|

ffmpeg -f video4linux2 -s 1280x720 -i /dev/video0 -vcodec libx264 -preset ultrafast -vprofile baseline -vlevel 1.0 -s 640x480 -b:v 800k -r 25 -pix_fmt yuv420p -f flv rtmp:
//192.168.0.194/myapp/mystream
|
然后ffmpeg的进程会显示如下

可以看到，在nginx-rtmp-module/test/www/下面使用的是jwplayer，这个player是一个AS建立出来的flash player
然后访问地址http://192.168.0.194/rtmp-publisher/player.html，就可以播放了
