視頻有兩總髮布方式
1、HTTP方式
這種方式要下載FLV視頻文件到本地播放，一旦FLV視頻文件下載完成，就不會消耗服務器的資源和帶寬，但是拖動功能沒有RTMP/RTMP流媒體方式強大，很多視頻網站都是用HTTP方式實現的，如：YouTube，土豆，酷6等
2、RTMP/RTMP流媒體方式
這種方式不用下載FLV視頻文件到本地，可以實時的播放flv文件，可以任意拖拽播放進度條，但是比較消耗服務器的資源
實驗目的:
讓Nginx支持flv和mp4格式文件，支持RTMP協議的直播和點播
準備工作
Nginx: http://nginx.org
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

1、安裝依賴包:
#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、安裝相關工具包
1). 安裝git，以後後面一些程序需要安裝下載需要用到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
如果make報錯如下，執行：yum install perl-ExtUtils-Embed -y
#make install
# git --version 看到版本輸出證明安裝成功
# 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
如果make過程出現了以下報錯，請安裝：yum -y install gcc gcc-c++,然後再重新執行./configure 再make
#make install
# cd ..
4). yadmi
yadmi的作用是爲flv文件添加關鍵幀，才能實現拖動播放
# 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 ..
使用方法：
# yamdi -i input.flv -o out.flv
給input.flv文件 添加關鍵幀，輸出爲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、安裝ffmpeg及其依賴包：
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
# tar zxvf faad2-2.7.tar.gz
# cd faad2-2.7
# ./configure
# make
# make install
# cd ..
8). 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 ..
9). Xvid

# make
# make install
# cd ..
10). ffmpeg
# git clone git://source.ffmpeg.org/ffmpeg
# cd ffmpeg
# ./configure --prefix=/opt/ffmpeg/ --enable-version3

--enable-libvorbis --enable-libx264 --enable-libxvid
--enable-shared --enable-gpl --enable-postproc --enable-nonfree
