ubuntu下使用nginx搭建流媒体服务器，实现视频点播

为了实现视频点播和直播，整了一天，看了N多博客，终于有了不小进展，在这里分享给大家。
什么是视频点播？可能你对这个名词不熟悉，但是爱奇艺，腾讯视频等这些视频播放软件想必你肯定知道。没错，视频点播就是在线观看某个视频。额，视频直播？这个就不解释了吧，美女直播，游戏直播等等，哈哈。

首先我们看如何实现视频点播，视频点播支持flv文件及H264编码视频，ACC编码音频的mp4文件：
第一步，创建单独的目录（因为软件较多，容易混乱），下载需要的软件:
我们需要下载nginx，pcre，zlib，openssl以及nginx-rtmp-module

mkdir workcd workwget http://nginx.org/download/nginx-1.10.3.tar.gzwget http://zlib.net/zlib-1.2.11.tar.gzwget https://ftp.pcre.org/pub/pcre/pcre-8.40.tar.gzwget https://www.openssl.org/source/openssl-1.0.2k.tar.gzwget https://github.com/arut/nginx-rtmp-module/archive/master.zip

第二步，分别解压这四个文件：

tar -zxvf 文件名

第三步，编译安装nginx：

./configure --prefix=/usr/local/nginx --with-debug --with-pcre=../pcre-8.40 --with-zlib=../zlib-1.2.11 --with-openssl=../openssl-1.0.2k --add-module=../nginx-rtmp-module-mastermakesudo make install

第四步，进入 /usr/local/nginx/conf，配置nginx.conf文件，在文件末尾添加如下内容：

rtmp {    server {        listen 1935;        application vod {            play /var/flvs; #指定存放视频文件的路径        }        application vod_http {            #myserver.com及服务器地址，如果只是本地播放，填写127.0.0.1:端口号 就行，端口好看配置文件中http监听的端口下同            play http://myserver.com/vod;         }        application vod_mirror {            play /var/local_mirror http://myserver.com/vod;        }    }}

然后，进入与conf文件夹同级的sbin目录下，运行：

sudo ./nginx

至此，服务器搭建完成，可以实现视频点播了。
视频点播测试：
播放位于 /video_test 下的file.flv视频文件：

ffplay rtmp://localhost/vod//file.flv

可以使用VLC这个播放器或者ffplay（需要安装ffmpeg），VLC自行百度安装即可。
ffmpeg安装：

sudo apt-add-repository ppa:jon-severinsson/ffmpegsudo apt-get updatesudo apt-get install ffmpeg
