nginx + ffmpeg
第一种方案:ffmpeg+nginx
新的ffmpeg已经支持HLS。(本人也参与了代码供献,给自己做个广告:))
点播:
生成hls分片:
ffmpeg -i <媒体文件> -c:v libx264 -c:a aac -f hls /usr/local/nginx/html/test.m3u8
直播:
ffmpeg -i udp://@:1234 -c:v libx264 -c:a aac -f hls -hls_list_size 5 -hls_wrap 5 /usr/local/nginx/html/test.m3u8
建立web服务器:
默认配置就可以。
server {
listen 80;
server_name localhost;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html;
index index.html index.htm;
}
}
启动nginx。
客户端访问:http://IP/test.m3u8
在windows上可以用vlc播放。
第二个方案,用nginx-rtmp-module
rtmp { server { listen 1935; chunk_size 4000; #HLS # For HLS to work please create a directory in tmpfs (/tmp/app here) # for the fragments. The directory contents is served via HTTP (see # http{} section in config) # # Incoming stream must be in H264/AAC. For iPhones use baseline H264 # profile (see ffmpeg example). # This example creates RTMP stream from movie ready for HLS: # # ffmpeg -loglevel verbose -re -i movie.avi -vcodec libx264 # -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1 # -f flv rtmp://localhost:1935/hls/movie # # If you need to transcode live stream use 'exec' feature. # application hls { live on; hls on; hls_path /tmp/app; hls_fragment 5s; } } } http { server { listen 80; location /hls { # Serve HLS fragments types { application/vnd.apple.mpegurl m3u8; video/mp2t ts; } alias /tmp/app; expires -1; } } }

Nginx:
官网:http://nginx.org/
下载:hg clone http://hg.nginx.org/nginx
nginx-rtmp-module:
官网:https://github.com/arut/nginx-rtmp-module
下载:git clone https://github.com/arut/nginx-rtmp-module.git
进入nginx源码根目录:
auto/configure--add-module=<path-to-nginx-rtmp-module>
make -f objs/Makefile
make -f objs/Makefile install
增加:http_ssl_module:
auto/configure--add-module=<path-to-nginx-rtmp-module> --with-http_ssl_module
http://nginx.org/en/docs/howto_build_on_win32.html
l Microsoft Visual C compiler.Microsoft Visual Studio® 8 and 10
l Msys
l Perl(如果要编译OpenSSL并且nginx支持SLL),例如:ActivePerl 或 Strawberry Perl.
l PCRE,zlib and OpenSSLlibraries sources.
l 设置MSYS、Perl、VC环境变量
运行vc设置环境变量脚本vcvarsall.bat(默认安装路径:C:\Program Files\MicrosoftVisual Studio 9.0\VC)
l 开始MSYS
l 建立编译和库目录
mkdir objs
mkdir objs/lib
cd objs/lib
tar -xzf ../../pcre-8.32.tar.gz
tar -xzf ../../zlib-1.2.7.tar.gz
tar -xzf ../../openssl-1.0.1e.tar.gz
l 运行配置脚本:
auto/configure --with-cc=cl --builddir=objs--prefix= \
--conf-path=conf/nginx.conf--pid-path=logs/nginx.pid \
--http-log-path=logs/access.log--error-log-path=logs/error.log \
--sbin-path=nginx.exe--http-client-body-temp-path=temp/client_body_temp \
--http-proxy-temp-path=temp/proxy_temp \
--http-fastcgi-temp-path=temp/fastcgi_temp\
--with-cc-opt=-DFD_SETSIZE=1024--with-pcre=objs/lib/pcre-8.32 \
--with-zlib=objs/lib/zlib-1.2.7--with-openssl=objs/lib/openssl-1.0.1e \
--with-select_module --with-http_ssl_module--with-ipv6
运行脚本:
nmake –f objs/Makefile
同
linux
Windows下下列功能不支持:
l execs
l static pulls
l auto_push
windows下用的是select模式:
events{
worker_connections 30; #默认为(1024),windows默认为64,所以需要修改此值小于64
}
rtmp://rtmp.example.com/app[/name]
app-应该是配置文件中的application块
name-可以为空
在源码要目下有个test目录。其中有测试配置文件和脚本。
l 环境:
服务器IP为:192.168.10.4。
安装根路径:/usr/local/nginx
在你的配置时,需要把IP换成你的服务器IP或域名。
l 建立媒体文件夹:
mkdir /usr/local/nginx/vod/flvs
l 准备媒体文件:
把媒体文件 a.flv 复制到 /usr/local/nginx/vod/flvs目录下。
l 准备网页
下载jwplayer:http://www.longtailvideo.com/players/jw-flv-player/
下载后,解压到:/usr/local/nginx/html/
建立测试页面test.html,也放到上面目录下。
<html>
<head>
<scriptsrc="/jwplayer/jwplayer.js"></script>
</head>
<body>
<divid='my-video'></div>
<scripttype='text/javascript'>
jwplayer('my-video').setup({
file:'rtmp://192.168.10.4/vod/a.flv',
width:'50%',
aspectratio:'3:2',
fallback:'false',
primary:'flash'
});
</script>
</body>

jwplayer('my-video').setup({
file:'rtmp://192.168.0.128/live/test', #live是applicatioin,test是直播缓存流文件
width:'50%',
aspectratio:'3:2',
fallback:'false',
primary:'flash'
});
</script>
</body>
</html>
l 启动服务
nginx
l 推流
用ffmpeg产生一个模拟直播源,向rtmp服务器推送
ffmpeg –i/usr/local/nginx/vod/flvs/a.flv-strict -2 -c:v libx264 -c:a aac -f flv rtmp://192.168.10.4/live/test
注意,源文件必须是H.264+AAC编码的。
192.168.10.4是运行nginx的服务器IP,l
ive是applicatioin,
test是直播缓存流文件,需要与配置文件中的直播缓存文件名一样。
