實驗目的:讓Nginx支持flv和mp4格式文件，同時支持Rtmp協議；同時打開rtmp的hls功能
資料:
HTTP Live Streaming（縮寫是 HLS）是一個由蘋果公司提出的基於HTTP的流媒體 網絡傳輸協議。
HLS只請求基本的HTTP報文，與實時傳輸協議（RTP)不同，HLS可以穿過任何允許HTTP數據通過的防火牆或者代理服務器。它也很容易使用內容分發網絡來傳輸媒體流。
使用ffmpeg來完成對flv、mp4、mp3等格式的轉化（點播實驗暫時不測試）
一、準備工作
模塊:nginx_mod_h264_streaming(支持h264編碼的視頻)
模塊:http_flv_module 支持flv
模塊:http_mp4_module 支持mp4

#git clone git://github.com/arut/nginx-rtmp-module.git
#tar zxvf pcre-8.12.tar.gz

--with-cc-opt=-I/opt/ffmpeg/include --with-ld-opt='-L/opt/ffmpeg/lib -Wl,-rpath=/opt/ffmpeg/lib'
#make && make install
三、修改nginx主配置文件,配置虛擬主機(這裏我們暫時只配置和測試點播，直播請看借鑑地址):
user nobody nobody;
worker_processes 4;
error_log logs/nginx_error.log info;
pid logs/nginx.pid;
worker_rlimit_nofile 51200;
events
{
use epoll;
worker_connections 51200;
}
#rtmp_auto_push on;
rtmp {
server {
listen 1935;
application vod {
play /opt/media/nginxrtmp/flv;
}
}
}
http
{
include mime.types;
default_type application/octet-stream;
server_names_hash_bucket_size 128;
client_header_buffer_size 32k;
large_client_header_buffers 4 32k;
client_max_body_size 50m ;
limit_conn_zone $binary_remote_addr zone=perip:256k;
limit_conn_log_level notice;
sendfile on;
tcp_nopush on;
keepalive_timeout 6000;#測試併發臨時調大
tcp_nodelay on;
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_http_version 1.0;
gzip_comp_level 2;
gzip_types text/plain application/x-javascript text/css application/xml;
gzip_vary on;
#log format
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
#支持flv
server
{
listen 8081;
server_name 192.168.0.33;
root /opt/pub/media/nginx; #http協議時候，flv視頻位置
location ~ .*.(flv|swf|mp4|wma|wmv)$ {
valid_referers none blocked *.xxxx.com http://localhost;
if ($invalid_referer) {
return 403;
}
}
location ~ \.flv$ {
flv;
limit_conn one 20;#限制客戶端併發連接數
limit_rate 200k;#限制每客戶端最大帶寬
}
location ~ \.mp4$ {
flv;
limit_conn one 20;
limit_rate 200k;
}
access_log logs/nginxflv_access.log main;
}
server
{
listen 8082;
server_name 192.168.0.33;
index index.html;
location / {
root /opt/pub/media/nginx-rtmp;
}
access_log logs/nginxrtmpflv_access.log main;
}
server {
listen 8080;
location /stat {
rtmp_stat all;
rtmp_stat_stylesheet stat.xsl;
}
location /stat.xsl {
root /opt/pub/soft/nginx-rtmp-module;
}
location / {
root /opt/pub/soft/nginx-rtmp-module/test/rtmp-publisher;
}
}
http://192.168.0.33:8080/stats 查看rtmp客戶請求信息
http://192.168.0.33:8081/index.html 查看nginx http協議時候的flv視頻
http://192.168.0.33:8082/index.html 查看nginx rtmp協議時候的flv視頻
四、基本功能測試:
播放器採用開源播放器jwplayer，將播放器放到index.html同級目錄下
NGINX-Http測試頁面index.html(切記http的時候需要給視頻添加關鍵幀)
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<param name="swfversion" value="6.0.65.0" />
<param name="flashvars" value="type=http&file=http://192.168.0.33:8081/2.flv&autostart=true">

ue" />
</object>
</body>
</html>
NGINX-RTMP測試頁面index.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>nginx-rtmp</title>
</head>
<body>
<div id="myElement"></div>
<object id="FlashID" classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="480" height="360">
<param name="movie" value="player.swf" />
<param name="quality" value="high" />
<param name="wmode" value="opaque" />
<param name="swfversion" value="6.0.65.0" />
<param name="flashvars" value="streamer=rtmp://192.168.0.33:1935/vod&file=2.flv&autostart=true">
<EMBED SRC="player.swf" WIDTH="480" HEIGHT="360" QUALITY="high" PLUGINSPAGE="http://www.macromedia.com/shockwave/download/i
ndex.cgi?P1_Prod_Version=ShockwaveFlash" flashvars="streamer=rtmp://192.168.0.33:1935/vod&file=2.flv&autostart=true" wmode="o
paque" />
</object>
</body>
</html>
頁面能打開正常播放就說明配置是正確的。
五、併發測試
NGINX-HTTP採用loadrunner測試（略）
NGINX-RTMP採用開源軟件flazr測試:
前提需要安裝jdk軟件
client.bat rtmp://192.168.0.33:1935/vod/2.flv -load 500
這裏的500是併發數
由於局域網的限制，帶寬測試到一定大小的時候就上不去了，故此步截圖不忽略。
