nginx流媒体服务器的安装和架设
由于最近公司项目需要，所以经过各种百度，nginx流媒体服务器的架设方法，先就我自己经过1天半的实验，安装步骤如下：
准备工作：
1、安装vmware虚拟机
2、安装centos6.0系统
3、架设lnmp服务器
4、采用nginx升级的方式安装nginx流媒体服务器（因为我们公司生产服务器上面就是nginx，已经正式使用，所以采用升级新增nginx模块的方式安装的）
对于已安装好的nginx，需要新增模块，我们可以重新编写安装，
1、先使用 nginx -V 查看原来编译都带了那些参数
nginx -V
查看是否安装了mp4模块的支持，如果没有，就先安装MP4模块
#添加mp4支持模块
wget http://h264.code-shop.com/download/nginx_mod_h264_streaming-2.2.7.tar.gz
tar -zxvf nginx_mod_h264_streaming-2.2.7.tar.gz
cd nginx_mod_h264_streaming-2.2.7
git clone git://github.com/arut/nginx-rtmp-module.git
2、添加新的参数 进行编译
安装git工具:
#mkdir soft-source
#cd soft-source
#wget http://www.codemonkey.org.uk/projects/git-snapshots/git/git-latest.tar.gz
#tar xzvf git-latest.tar.gz
#cd git-2013-02-04
#autoconf
#./configure
#make && make install
# git --version
git version 1.8.1.GIT
#cd ..
安装ffmpeg及其依赖包：
++++++++Yasm+++++++++++
#wget http://www.tortall.net/projects/yasm/releases/yasm-1.2.0.tar.gz
#tar xzvf yasm-1.2.0.tar.gz
#cd yasm-1.2.0
#./configure
#make
#make install
#cd ..
++++++++x264+++++++++++
#git clone git://git.videolan.org/x264
#cd x264
#./configure --enable-shared
#make
#make install
#cd ..
++++++++LAME+++++++++++
#wget http://downloads.sourceforge.net/project/lame/lame/3.99/lame-3.99.5.tar.gz
#tar xzvf lame-3.99.5.tar.gz
#cd lame-3.99.5
#./configure --enable-nasm
#make
#make install
#cd ..
++++++++libogg+++++++++++
#wget http://downloads.xiph.org/releases/ogg/libogg-1.3.0.tar.gz
#tar xzvf libogg-1.3.0.tar.gz
#cd libogg-1.3.0
#./configure
#make
#make install
#cd ..
++++++++libvorbis+++++++++++
#wget http://downloads.xiph.org/releases/vorbis/libvorbis-1.3.3.tar.gz
#tar xzvf libvorbis-1.3.3.tar.gz
#cd libvorbis-1.3.3
#./configure
#make
#make install
#cd ..
++++++++libvpx+++++++++++
#git clone http://git.chromium.org/webm/libvpx.git
#cd libvpx
#./configure --enable-shared
#make
#make install
#cd ..
++++++++FAAD2+++++++++++
#wget http://downloads.sourceforge.net/project/faac/faad2-src/faad2-2.7/faad2-2.7.tar.gz
#tar zxvf faad2-2.7.tar.gz
#cd faad2-2.7
#./configure
#make
#make install
#cd ..
++++++++FAAC+++++++++++
#wget http://downloads.sourceforge.net/project/faac/faac-src/faac-1.28/faac-1.28.tar.gz
#tar zxvf faac-1.28.tar.gz
#cd faac-1.28
#./configure
#make
#make install
#cd ..
++++++++Xvid+++++++++++
#wget http://downloads.xvid.org/downloads/xvidcore-1.3.2.tar.gz
#tar zxvf xvidcore-1.3.2.tar.gz
#cd xvidcore/build/generic
#./configure
#make
#make install
cd ..
安装ffmpeg
https://ffmpeg.org/download.html
tar -jvxf ffmpeg-3.0.1.tar.bz2
cd ffmpeg-3.0.1
./configure --prefix=/usr/local/ffmpeg/ --enable-version3 --enable-libvpx --enable-libfaac --enable-libmp3lame --enable-libvorbis --enable-libx264 --enable-libxvid --enable-shared --enable-gpl --enable-postproc --enable-nonfree --enable-avfilter --enable-pthreads
修改/etc/ld.so.conf如下:
include ld.so.conf.d/*.conf
/lib
/lib64
/usr/lib
/usr/lib64
/usr/local/lib
/usr/local/lib64
/opt/ffmpeg/lib
#ldconfig
进入nginx的源码目录，进行nginx的编译安装
./configure --prefix=/usr/local/nginx --add-module=/usr/local/nginx_mod_h264_streaming-2.2.7 --user=www --group=www --with-http_stub_status_module --with-http_ssl_module --with-http_spdy_module --with-http_gzip_static_module --with-ipv6 --with-http_sub_module --with-http_flv_module --with-http_mp4_module --add-module=/usr/local/nginx-rtmp-module --with-cc-opt=-I/usr/local/ffmpeg/include --with-ld-opt=\'-L/usr/local/ffmpeg/lib -Wl,-rpath=/usr/local/ffmpeg/lib\'
3、编译
make
注意，这里就不要make install 了，否则就是覆盖安装了
4、替换nginx 二进制文件
先备份
cp /usr/local/nginx/sbin/nginx /usr/local/nginx/sbin/nginx.bak
在拷贝新的二进制文件
cp ./objs/nginx /usr/local/nginx/sbin/
5、yadmi的作用是为flv文件添加关键帧，才能实现拖动播放
#下载yadmi
wget https://sourceforge.net/projects/yamdi/files/yamdi/1.4/yamdi-1.4.tar.gz/download
#安装yadmi
tar xzvf yamdi-1.4.tar.gz
cd yamdi-1.4
make && make install
使用方法：yamdi -i input.flv -o out.flv
给input.flv文件 添加关键帧，输出为out.flv文件
6、修改nginx配置
user www www;
worker_processes auto;
error_log /home/wwwlogs/nginx_error.log crit;
pid /usr/local/nginx/logs/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.

}
重启nginx服务：
下载jwplayer的播放器：
编写测试页面：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">
<HTML>
<HEAD>
<TITLE>后台管理系统登录</TITLE>
<META http-equiv=Content-Type content="text/html; charset=utf-8">
<script src="jwplayer/jquery-1.8.1.min.js" type="text/javascript"></script>
<script src="jwplayer/jwplayer.js" type="text/javascript"></script>
<script type="text/javascript">jwplayer.key="+iYXuspbJGjMrCdDoq09NROARMASj+nhqP6pAw==";</script>
<body>
<div id="container"></div>
<input type="button" class="player-play" value="播放" />
<input type="button" class="player-stop" value="停止" />
<input type="button" class="player-status" value="取得状态" />
<input type="button" class="player-current" value="当前播放秒数" />
<input type="button" class="player-goto" value="转到第30秒播放" />
<input type="button" class="player-length" value="视频时长(秒)" />
</body>
</HTML>
<script type="text/javascript">
var thePlayer; //保存当前播放器以便操作
$(function() {
thePlayer = jwplayer(\'container\').setup({
flashplayer: \'jwplayer/jwplayer.flash.swf\',
file: \'video/test6.mp4\',
width: 500,
height: 350,
dock: false
});
//播放 暂停
$(\'.player-play\').click(function() {
if (thePlayer.getState().toUpperCase() != \'PLAYING\') {
thePlayer.play(true);
this.value = \'暂停\';
} else {
thePlayer.play(false);
this.value = \'播放\';
}
});
//停止
$(\'.player-stop\').click(function() { thePlayer.stop(); });
//获取状态
$(\'.player-status\').click(function() {
var state = thePlayer.getState();
state = state.toUpperCase();
var msg;
switch (state) {
case \'BUFFERING\':
msg = \'加载中\';
break;
case \'PLAYING\':
msg = \'正在播放\';
break;
case \'PAUSED\':
msg = \'暂停\';
break;
case \'IDLE\':
msg = \'停止\';
break;
}
alert(msg);
});
//获取播放进度
$(\'.player-current\').click(function() { alert(thePlayer.getPosition()); });
//跳转到指定位置播放
$(\'.player-goto\').click(function() {
if (thePlayer.getState().toUpperCase() != \'PLAYING\') { //若当前未播放，先启动播放器
thePlayer.play();
}
thePlayer.seek(30); //从指定位置开始播放(单位：秒)
});
//获取视频长度
$(\'.player-length\').click(function() { alert(thePlayer.getDuration()); });
});
</script>
注意，这是就可以播放mp4,flv的视频格式了，如果不能够拖拽，就使用工具添加关键帧：
可以使用“格式工厂”对视频做编码转换 h262格式
