让Nginx支持flv和mp4格式文件，支持RTMP协议的直播和点播；
同一时候打开RTMP的HLS功能
资料:
HTTP Live Streaming（缩写是 HLS）是一个由苹果公司提出的基于HTTP的流媒体网络传输协议。
HLS仅仅请求主要的HTTP报文，与实时传输协议（RTP)不同，HLS能够穿过不论什么同意HTTP数据通过的防火墙或者代理server。
它也非常easy使用内容分发网络来传输媒体流。
使用ffmpeg来完毕对flv、mp4、mp3等格式的转化（点播实验临时不測试）
一、准备工作
Nginx: http://nginx.org
模块:nginx_mod_h264_streaming(支持h264编码的视频)
模块:http_flv_module 支持flv
模块:http_mp4_module 支持mp4

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、安装相关工具包
1). git
# mkdir soft-source
# cd soft-source
# wget http://codemonkey.org.uk/projects/git-snapshots/git/git-latest.tar.xz
# xz -d git-latest.tar.xz
# tar xzvf git-latest.tar
# cd git-2014-06-27
# autoconf
# ./configure
# make && make install
# git --version
git version 2.0.0.GIT
# cd ..
2). zlib
# wget http://zlib.net/zlib-1.2.8.tar.gz
# tar -zxvf zlib-1.2.8.tar.gz cd zlib-1.2.8
# ./configure
# make
# make install
# cd ..
3). pcre
# wget http://exim.mirror.fr/pcre/pcre-8.12.tar.gz
# tar zxvf pcre-8.12.tar.gz
# cd pcre-8.12
# ./configure
# make && make install
# cd ..
4). yadmi
yadmi的作用是为flv文件加入关键帧。才干实现拖动播放
# 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
# cd ..
用法：
# yamdi -i input.flv -o out.flv
给input.flv文件 加入关键帧，输出为out.flv文件
5). OpenSSL
# wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz
# tar -zxvf openssl-1.0.1c.tar.gz
# ./config
# make
# make install
3、安装ffmpeg及其依赖包：
1). 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 ..
2). x264
# git clone git://git.videolan.org/x264
# cd x264
# ./configure --enable-shared
# make
# make install
# cd ..
3). 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 ..
4). 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 ..
5). 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 ..
6). libvpx
# git clone http://git.chromium.org/webm/libvpx.git
# cd libvpx
# ./configure --enable-shared
# make
# make install
# cd ..
7). FAAD2
# wget http://downloads.sourceforge.net/project/faac/faad2-src/faad2-2.7/faad2-2.7.tar.gz
