过了个年，突然忘了很多事情，可能我真是上了年龄。
一.安装编译时说需要的扩展
yum install automake autoconf make gcc gcc-c++
二.安装nginx-rtmp-module
2.1第一种方式比较简单
yum install pcre pcre-devel yum install zlib zlib-devel yum install openssl openssl--devel
然后下载nginx,nginx-rtmp-module模块，并解压
git clone https://github.com/arut/nginx-rtmp-module.git
wget http://nginx.org/download/nginx-1.7.4.tar.gz
解压略（我们这里假定解压目录在 /usr/tmp中）
注册并安装nginx
cd nginx-1.7.4#../configure --prefix=/usr/local/nginx --with-http_stub_status_module[可选] --with-http_ssl_module[可选] --with-http_gzip_static_module[可选] --with-http_flv_module[可选] --with-http_mp4_module [可选]--add-module=/usr/tmp/nginx-rtmp-module-master#make#make install
注：如果使用flv，MP4点播的话，要注意nginx 1.1.3之后已经默认支持mp4,flv模块，无须第三方模块支持，如果这里不配置，那么mp4和flv视频点播播放将会很慢
2.2第二种方式
需要下载的阔扩展()：
1. wget http://www.openssl.org/source/openssl-0.9.8l.tar.gz (系统默认带有openssl) 2. wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-8.00.tar.bz2 3. wget http://www.zlib.net/zlib-1.2.3.tar.bz2 4. git clone https://github.com/arut/nginx-rtmp-module.git 5. wget http://nginx.org/download/nginx-1.7.4.tar.gz
把这些玩意都缩后，就会有（假定解压目录/usr/tmp/）：
1. openssl-0.9.8l 2. pcre-8.00 3. zlib-1.2.3 4. nginx-rtmp-module-master 5. nginx-1.7.4
注册并安装nginx
cd nginx-1.7.4#./configure --prefix=/usr/local/nginx --with-http_realip_module --with-http_sub_module --with-http_flv_module --with-http_mp4_module --with-http_dav_module --with-http_gzip_static_module --with-http_stub_status_module --with-http_addition_module --with-pcre=/usr/tmp/pcre-8.00 --with-openssl=/usr/tmp/openssl-0.9.8l --with-http_ssl_module --with-zlib=/usr/tmp/zlib-1.2.3 --add-module=/usr/tmp/nginx-rtmp-module#make#make install
三.配置nginx.conf
rtmp { server { listen 1935; chunk_size 4000; # TV mode: one publisher, many subscribers 电视直播模式，1对多 application mytv { # enable live streaming live on; # record first 1K of stream record all; record_path /tmp/av; record_max_size 1K; # append current timestamp to each flv record_unique on; # publish only from localhost allow publish 127.0.0.1; deny publish all; #allow play all; } # Transcoding (ffmpeg needed) application big { live on; #将推过来的媒体文件流转码至small exec ffmpeg -re -i rtmp://localhost:1935/$app/$name -vcodec flv -acodec copy -s 32x32 -f flv rtmp://localhost:1935/small/${name}; } application small { live on; # Video with reduced resolution comes here from ffmpeg } application webcam { live on; # Stream from local webcam exec_static ffmpeg -f video4linux2 -i /dev/video0 -c:v libx264 -an -f flv rtmp://localhost:1935/webcam/mystream; } application mypush { live on; # Every stream published here # is automatically pushed to # these two machines push rtmp1.example.com; push rtmp2.example.com:1934; } application mypull { live on;#拉流 # Pull all streams from remote machine # and play locally pull rtmp://rtmp3.example.com pageUrl=www.example.com/index.html; } application mystaticpull { live on; # Static pull is started at nginx start pull rtmp://rtmp4.example.com pageUrl=www.example.com/index.html name=mystream static; } # video on demand#点播 application vod { play /var/flvs; } application vod2 { play /var/mp4s; } # Many publishers, many subscribers # no checks, no recording#视频聊天 application videochat { live on; # The following notifications receive all # the session variables as well as # particular call arguments in HTTP POST # request # Make HTTP request & use HTTP retcode # to decide whether to allow publishing # from this connection or not on_publish http://localhost:8080/publish; # Same with playing on_play http://localhost:8080/play; # Publish/play end (repeats on disconnect) on_done http://localhost:8080/done; # All above mentioned notifications receive # standard connect() arguments as well as # play/publish ones.

中有个big->small转换有些问题，需要安装ffmpeg才行，如果要装ffmpeg请参考
