這里實(shí)現(xiàn)了簡(jiǎn)單Nginx+ffmpeg 推本地mp4視頻文件的功能，以后將會(huì)繼續(xù)更新

環(huán)境

系統(tǒng)環(huán)境：centos release 6.7 (Final)

需求

利用nginx和ffmpeg搭建流媒體服務(wù)器

利用nginx和ffmpeg搭建流媒體服務(wù)器(直播流)，其他流后續(xù)會(huì)有所更新

關(guān)于用Nginx搭建flv,mp4,hls流媒體服務(wù)器的技術(shù)干貨！

模塊:nginx_mod_h264_streaming（支持h264編碼MP4格式的視頻）

模塊:http_flv_module （支持flv）

模塊:http_mp4_module （支持mp4）

模塊: nginx-rtmp-module （支持rtmp協(xié)議，也支持HLS）

步驟

（1）模塊下載和解壓

wget http://nginx.org/download/nginx-1.6.0.tar.gz

wget http://h264.code-shop.com/download/nginx_mod_h264_streaming-2.2.7.tar.gz

wget http://sourceforge.net/projects/pcre/files/pcre/8.35/pcre-8.35.tar.gz

wget http://zlib.net/zlib-1.2.8.tar.gz

wget http://www.openssl.org/source/openssl-1.0.1g.tar.gz

wget -O nginx-rtmp-module.ziphttps://github.com/arut/nginx-rtmp-module/archive/master.zip

將所有模塊統(tǒng)一放置在/usr/local/nginx_sources目錄下，方便管理

安裝步驟：openssl-->zlib-->pcre

1.openssl

./config --prefix=/usr/local/openssl -->make -->make install

2. zlib

./configure --prefix=/usr/local/zlib-->make -->make install

3.pcre

./configure ==prefix=/usr/local/pcre -->make -->make install

（2）配置命令，會(huì)生成makefile文件

cd /usr/local/nginx-1.6.0

./configure

--prefix=/usr/local/nginx

--add-module=/usr/tmp/nginx_mod_h264_streaming-2.2.7

--add-module=/usr/tmp/nginx-rtmp-module-master

--with-http_flv_module

--with-http_mp4_module

--with-http_stub_status_module

--with-http_ssl_module

--with-pcre=/usr/tmp/pcre-8.35

--with-zlib=/usr/tmp/zlib-1.2.8

--with-debug

--with-openssl=/usr/tmp/openssl-1.0.1g

錯(cuò)誤提示：如果在configure過程中出現(xiàn)以下錯(cuò)誤：

/root/nginx_mod_h264_streaming-2.2.7/src/ngx_http_streaming_module.c: In function ‘ngx_streaming_handler’:

/root/nginx_mod_h264_streaming-2.2.7/src/ngx_http_streaming_module.c:158: error: ‘ngx_http_request_t’ has no member named ‘zero_in_uri’

make[1]: *** [objs/addon/src/ngx_http_h264_streaming_module.o] Error 1

make[1]: Leaving directory `/root/nginx-0.8.54'

make: *** [build] Error 2

那么將src/ngx_http_streaming_module.c文件中以下代碼刪除或者是注釋掉就可以了：

/* TODO: Win32 */

if (r->zero_in_uri)

{

return NGX_DECLINED;

}

如果你沒有對(duì)這個(gè)文件做個(gè)更改，那么應(yīng)該在源碼的第157-161行。

cd /usr/local/nginx/sbin--> ./nginx ( 啟動(dòng)nginx) -->netstat -nltp(如果80端口啟動(dòng)就說明安裝成功)

-->在瀏覽器輸入http://172.19.197.244:80

(3)開始安裝ffmpeg，參考安裝文檔http://www.voidcn.com/blog/yangguangmeng/article/p-4881242.html（轉(zhuǎn)載）

安裝ffmpeg:(如果系統(tǒng)不支持上網(wǎng)功能，可以自行從網(wǎng)下先下載，再上傳到服務(wù)器)

下載FFmpeg和libx264的包

ffmpeg-3.2.4.tar.bz2 last_x264.tar.bz2

libx264需要yasm,所以先安裝yasm

zypper install yasm

然后安裝libx264

zypper install libx264-dev

解壓縮libx264

tar -xzvf last_x264.tar.bz2

安裝libx264

./configure --enable-shared --enable-pthread --enable-pic

make

make install

然后安裝ffmpeg,ffmpeg有許多依賴包,需要一個(gè)一個(gè)先安裝,可能安裝過程中還需要下載其他依賴包，這個(gè)安裝過程依照提示進(jìn)行下載安裝即可

1. libfaac

zypper install libfaac-dev

2. libmp3lame

zypper install libmp3lame-dev

3. libtheora

zypper install libtheora-dev

4. libvorbis

zypper install libvorbis-dev

5. libxvid

zypper install libxvidcore-dev

6. libxext

zypper install libxext-dev

7. libxfixes

zypper install libxfixes-dev

依賴包安裝完后,安裝ffmpeg

先解壓縮ffmpeg

tar -xzvf ffmpeg-3.2.4.tar.bz2

cd /usr/local/ffmpeg_sources #我把它統(tǒng)一放在/usr/local/ffmpeg_sources目錄

cd ffmpeg ffmpeg-3.2.4

./configure --prefix=/usr/local/ffmpeg --enable-gpl --enable-version3 --enable-nonfree --enable-postproc --enable-pthreads --enable-libmp3lame --enable-libtheora --enable-libx264 --enable-libxvid --enable-x11grab

make && make install

cd /usr/local/nginx/conf -->vi nginx.conf

錯(cuò)誤提示：安裝ffmpeg出現(xiàn)錯(cuò)誤， cannot open shared object file

vi /etc/ld.so.conf

在尾部增加一行：/usr/local/lib

-->ldconfig

溫馨提示：如果編譯過程中出現(xiàn)一些錯(cuò)誤，學(xué)會(huì)看config.log，里面會(huì)有錯(cuò)誤提示及解決方法

5、配置好后判斷配置是否正確

/usr/local/nginx/sbin/nginx -t

-->重啟nginx /usr/local/nginx/sbin/nginx -s reload

-->查看是否已經(jīng)啟動(dòng)流媒體服務(wù)器的端口

netstat -anp | grep 1935

6、開始推流，我推的是直播流

-->cd /usr/local/ffmpeg_sources/ffmpeg-3.2.4

-->./ffmpeg -re -i "/usr/local/WEB.mp4" -vcodec libx264 -vprofile baseline -acodec aac -ar 44100 -strict -2 -ac 1 -f flv -s 1280x720 -pix_fmt yuv420p -q 10 rtmp://172.19.197.244:1935/myapp/test

-->make && make install

7. 搭建客戶端測(cè)試環(huán)境，本文測(cè)試播放器使用的是jwplayer

-->準(zhǔn)備網(wǎng)頁

-->下載jwplayer:http://www.longtailvideo.com/players/jw-flv-player/

-->下載后，解壓到：/usr/local/nginx/html/

-->建立測(cè)試頁面test.html，也放到上面目錄下。

<html>

<head>

<script src="jwplayer/jwplayer.js"></script>

</head>

<body>

<div id='my-video'></div>

<script type='text/JAVAscript'>

jwplayer('my-video').setup({

file:'rtmp://172.19.197.244/myapp/test', //#live是applicatioin,test是直播緩存流文件

width:'100%',

aspectratio:'3:2',

fallback:'false',

primary:'flash'

});

</script>

</body>

</html>

ps:由于腳本默認(rèn)不調(diào)用JavaScript函數(shù)，所以我們要去官網(wǎng)下載這個(gè)函數(shù)配置文件，將它放在

/usr/local/nginx/html/jwplayer/jwplayer.js，由于jwplayer.js是沒有的，需要自己創(chuàng)建

-->下載網(wǎng)址：https://github.com/jwplayer/jwdeveloper-demos/blob/master/demos/toolbox/live-streaming/index.html
