[nginx]使用nginx搭建rtmp流媒体服务器环境

一.准备工作
1、安装依赖包:
#yum -y install gcc glibc glibc-devel make nasm pkgconfig lib-devel openssl-devel expat-devel gettext-devel libtool mhash.x86_64 perl-Digest-SHA1.x86_64
2、安装git工具:
2.1 添加repository
RHEL/CentOS 6
i686
cd /etc/yum.repos.d/
wget http://geekery.altervista.org/geekery-el6-i686.repo
x86_64
cd /etc/yum.repos.d/
wget http://geekery.altervista.org/geekery-el6-x86_64.repo

2.2 install RPMforge
RHEL/CentOS 6
i686:
wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.i686.rpm
rpm -ivh rpmforge-release-0.5.2-2.el6.rf.i686.rpm
x86_64:
wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
rpm -ivh rpmforge-release-0.5.2-2.el6.rf.x86_64.rpm
2.3 install epel
i686: rpm -ivh http://dl.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm x86_64: rpm -ivh http://dl.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm
2.4 开始使用yum安装git
#yum -y install git
#git --version
#git version 1.7.10
3.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
++++++++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
编译FAAC-1.28时遇到错误：
mpeg4ip.h:126: error: new declaration ‘char* strcasestr(const char*, const char*)’
解决方法：
修改此文件mpeg4ip.h
修改前：
#ifdef __cplusplus
extern "C" {
#endif
char *strcasestr(const char *haystack, const char *needle);
#ifdef __cplusplus
}
#endif

修改后：
#ifdef __cplusplus
extern "C++" {
#endif
const char *strcasestr(const char *haystack, const char *needle);
#ifdef __cplusplus
}
#endif
++++++++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 ..
#git clone git://source.ffmpeg.org/ffmpeg
#cd ffmpeg
#./configure --prefix=/opt/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
#make && make install
#cd ..

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

安装yamdi
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 http://sourceforge.net/projects/yamdi/files/yamdi/1.4/yamdi-1.4.tar.gz/download
#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
