1.更新ubuntu源

sudo apt-get update
目的是为了 保持ubuntu的依赖正确

2.安装必要lib

sudo apt-get install build-essential libpcre3 libpcre3-dev libssl-dev
sudo apt-get install gcc make automake bzip2 unzip patch subversion libjpeg62-dev

cd ~
mkdir working
wget http://www.tortall.net/projects/yasm/releases/yasm-1.2.0.tar.gz
tar zxvf yasm-1.2.0.tar.gz
cd yasm-1.2.0
./configure
make && make install
cd ~/working
如果遇到权限不够  切换root  chmod 777 加权限
保证下面的安装都在 working目录下

3. 卸载系统原有的ffmgeg和x.264，没有则跳过：

apt-get remove ffmpeg x264

4 先安装一些Mplayer编码库(仅限于64位系统):

wget -c http://www2.mplayerhq.hu/MPlayer/releases/codecs/essential-amd64-20071007.tar.bz2
tar xvjf essential-amd64-20071007.tar.bz2
mkdir /usr/local/lib/codecs
cp -Rvp essential-amd64-20071007/* /usr/local/lib/codecs/
编辑下面文件
vim /etc/ld.so.conf
添加以下两行到上面的文件里
 /usr/lib 
 /usr/local/lib

5 再安装依赖库

sudo apt-get install make automake g++ bzip2 python unzip patch subversion ruby build-essential git-core checkinstall yasm texi2html libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libsdl1.2-dev libtheora-dev libvdpau-dev libvorbis-dev libvpx-dev libx11-dev libxfixes-dev libxvidcore-dev zlib1g-dev

6 安装 x264

sudo git clone git://git.videolan.org/x264.git
cd x264
sudo ./configure --enable-shared --prefix=/usr/local
sudo make
sudo make install
cd ~/working

7 安装libvpx:

cd ~/working
下载 libvpx-1.4.0，
http://download.csdn.net/download/lsc1818/8929949
tar xvjf libvpx-1.4.0.tar.bz2
cd libvpx-1.4.0
sudo ./configure --enable-shared --prefix=/usr/local
make && make install
cd ~/working

8 安装FFmpeg

cd ~/working
wget http://ffmpeg.org/releases/ffmpeg-2.7.2.tar.bz2
tar xvjf ffmpeg-2.7.2.tar.bz2
cd ffmpeg-2.7.2
 ./configure --enable-gpl --enable-version3 --enable-shared --enable-nonfree --enable-postproc --enable-libfaac --enable-libmp3lame --enable-libopencore-amrnb --enable-libopencore-amrwb --enable-libtheora --enable-libvorbis --enable-libvpx  --enable-libxvid --enable-libx264 --extra-cflags=-I/usr/local/include --extra-ldflags=-L/usr/local/lib
 make && make install
 cd ~/working
 让动态链接库被系统共享
 ldconfig

9 安装mplayer and mencoder 不必须

apt-get install libmp3lame-dev 
svn checkout svn://svn.mplayerhq.hu/mplayer/trunk mplayer 
cd mplayer/
./configure
make && make install

10 安装flvtool2： 不必须

sudo apt-get install ruby
gem install flvtool2

11 查看一下已经安装好的音频和视频编码器 不必须

sudo apt-get install mencoder
查看所有所支持的音频编码
mencoder -oac help
查看所有所支持的视频编码
mencoder -ovc help

12 安装配置Nginx:

先安装各种依赖(nginx需要pcre支持,yamdi用来为flv创建关键帧才能随意拖动)

sudo apt-get install gcc g++ libssl-dev zlib1g-dev libpcre3-dev yamdi

下载所需的nginx模块

第一个是nginx_mod_h264_streaming，让nginx支持flv/mp4流播放

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
注意：先要修改一下源码，注释掉
nginx_mod_h264_streaming-2.2.7/src/ngx_http_streaming_module.c
的158到161行
sudo gedit nginx_mod_h264_streaming-2.2.7/src/ngx_http_streaming_module.c
/* TODO: Win32 */
//if (r->zero_in_uri)
// {
// return NGX_DECLINED;
// }
第二个是nginx-rtmp-module，让nginx支持rtmp/hls协议
wget -O nginx-rtmp-module.zip https://github.com/arut/nginx-rtmp-module/archive/master.zip
unzip nginx-rtmp-module.zip
下载清缓存的模块
wget -O ngx_cache_purge.zip https://github.com/FRiCKLE/ngx_cache_purge/archive/master.zip
unzip ngx_cache_purge.zip
下载安装nginx:
wget http://nginx.org/download/nginx-1.8.0.tar.gz
tar zxvf nginx-1.8.0.tar.gz
cd nginx-1.8.0
./configure --user=daemon --group=daemon --prefix=/usr/local/nginx/ --add-module=../nginx-rtmp-module-master --add-module=../ngx_cache_purge-master --add-module=../nginx_mod_h264_streaming-2.2.7 --with-http_stub_status_module --with-http_ssl_module --with-http_sub_module --with-http_gzip_static_module --with-http_flv_module
make && make install

13 设置nginx为系统服务

sudo wget https://raw.github.com/JasonGiedymin/nginx-init-ubuntu/master/nginx -O /etc/init.d/nginx
sudo chmod +x /etc/init.d/nginx
sudo update-rc.d nginx defaults
sudo service nginx start//开启
sudo service nginx stop //停止，列出
开启后，浏览localhost

14 各种配置nginx:

编辑/usr/local/nginx/conf/nginx.conf文件

sudo gedit /usr/local/nginx/conf/nginx.conf
#user  nobody;
worker_processes  1;
error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
pid        logs/nginx.pid;
events {
    use epoll;
    worker_connections  1024;
}
rtmp {
    server {
        listen 1935;
        chunk_size 4000;
        # video on demand
        application vod {
            play /mnt/media/vod;
        }
        # HLS
        # HLS requires libavformat & should be configured as a separate
        # NGINX module in addition to nginx-rtmp-module:
        # ./configure … –add-module=/path/to/nginx-rtmp-module/hls …
        # For HLS to work please create a directory in tmpfs (/tmp/app here)
        # for the fragments. The directory contents is served via HTTP (see
        # http{} section in config)
        #
        # Incoming stream must be in H264/AAC/MP3. For iPhones use baseline H264
        # profile (see ffmpeg example).
        # This example creates RTMP stream from movie ready for HLS:
        #
        # ffmpeg -loglevel verbose -re -i movie.avi  -vcodec libx264
        #    -vprofile baseline -acodec libmp3lame -ar 44100 -ac 1
        #    -f flv rtmp://localhost:1935/hls/movie
        #
        # If you need to transcode live stream use ‘exec’ feature.
        #
        application hls {
            hls on;
            hls_path /mnt/media/app;
            hls_fragment 10s;
        }
    }
}
http {
    include mime.types;
    default_type application/octet-stream;
    sendfile on;
    keepalive_timeout 65;
    gzip on;
     #log format
    log_format  access  ‘$remote_addr – $remote_user [$time_local] “$request” ‘
             ‘$status $body_bytes_sent “$http_referer” ‘
             ‘”$http_user_agent” $http_x_forwarded_for’;    
     #定义一个名为addr的limit_zone,大小10M内存来存储session
    limit_conn_zone $binary_remote_addr zone=addr:10m;     
    server {
        listen 8080;
         server_name localhost;
         # HTTP can be used for accessing RTMP stats
        # This URL provides RTMP statistics in XML
        location /stat {
            rtmp_stat all;
            rtmp_stat_stylesheet stat.xsl;
        }
        location /stat.xsl {
            root /mnt/soft/nginx-rtmp-module-master;
        }
         location /control {
            rtmp_control all;
        }
        location / {
            root /mnt/soft/nginx-rtmp-module-master/test/rtmp-publisher;
        }
    }
     server {
        listen 80;
         server_name localhost;
        location / {
                root /mnt/wwwroot;
                index index.html;
              }         
         location ~ \.flv$ {
               root /mnt/media/vod;
             flv;
             limit_conn addr 20;
             limit_rate 200k;
        }
        location ~ \.mp4$ {
             root /mnt/media/video;
             mp4;
             limit_conn addr 20;
             limit_rate 200k;
        }
         location /hls {
            # Serve HLS fragments
            alias /mnt/media/app;
        }
         access_log  logs/nginxflv_access.log access;
    }
}
注意 如果启动不了，是文件权限错误。手动建立文件夹
 /mnt/media/video -> 存放原始视频
 /mnt/media/vod  -> 存放转换后的flv和mp4视频,供http或rtmp访问

15 m3u8切片

git clone https://github.com/johnf/m3u8-segmenter.git
直接找到m3u8-segmenter.c 所在目录
cd m3u8-segmenter/
gcc -Wall -g m3u8-segmenter.c -o segmenter -lavformat -lavcodec -lavutil
拷贝至软件目录
cp segmenter /usr/bin/
切片势力    原文件为  vp5.flv  转换为vp5.ts
ffmpeg -i vp5.flv -acodec copy -vcodec libx264 vp5.ts
segmenter 转换为m3u8 :
segmenter -i vp5.ts -d 10 -p onedemo -m vp5.m3u8 -u http://localhost/videox/
-p one demo 是分片的名字
-u 是访问的链接  比如现在的网站ip是 192.168.2.107  那么填写 http://192.168.2.107/video/
最后把ts文件与M3U8文件拷贝到网站对应的目录下 即可

未解决问题：
1 网页播放m3u8，原计划使用ckplayer 但是一直有错，没有成功
2 据观察，m3u8同样能够下载？
