使用Nginx+FFMPEG搭建HLS直播转码服务器

admin • • C/C++ • 阅读 143

目的:使Nginx支持Rtmp协议推流，并支持hls分发功能及FFMPEG转码多码率功能。

一、准备工作

模块:nginx-rtmp-module-master(支持rtmp协议)

下载地址:

http://nginx.org

https://github.com/arut/nginx-rtmp-module

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 gcc-c++ wget xz perl-ExtUtils-MakeMaker package libcurl-devel unzip

2、安装Git工具:

#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 xvf git-latest.tar

#cd git-2016-06-20/

#autoconf

#./configure

#make && make install

# git --version

git version 2.9.0

#cd ..

3、安装ffmpeg及其依赖包：

++++++++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 ..

++++++++x264+++++++++++

#git clone git://git.videolan.org/x264

#cd x264

#./configure --enable-shared

#make

#make install

#cd ..

++++++++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 ..

++++++++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 ..

++++++++libvorbis+++++++++++

echo /usr/local/lib >> /etc/ld.so.conf; ldconfig

#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 ..

++++++++libvpx+++++++++++

git clone https://github.com/webmproject/libvpx

cd libvpx

./configure --enable-shared

make

make install

cd ..

++++++++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 ..

++++++++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

# sed -i 's@^char strcasestr@//char strcasestr@' ./common/mp4v2/mpeg4ip.h



#./configure

#make

#make install

#cd ..

++++++++Xvid+++++++++++

#wget http://downloads.xvid.org/downloads/xvidcore-1.3.2.tar.gz

#tar zxvf xvidcore-1.3.2.tar.gz

#cd xvidcore/build/generic

#./configure

#make

#make install

cd ../../../

++++++++ffmpeg+++++++++++

#git clone git://source.ffmpeg.org/ffmpeg

#cd ffmpeg

#./configure --prefix=/opt/ffmpeg/ --enable-version3 --enable-libvpx --enable-libfaac --enable-libmp3lame --enable-libvorbis --enable-libx264 --enable-libxvid --enable-shared --enable-gpl --enable-postproc --enable-nonfree --enable-avfilter --enable-pthreads

#make && make install

#cd ..



修改/etc/ld.so.conf如下:

include ld.so.conf.d/*.conf

/lib

/lib64

/usr/lib

/usr/lib64

/usr/local/lib

/usr/local/lib64

/opt/ffmpeg/lib


#ldconfig

【说明】

动态装入器找到共享库要依靠两个文件 — /etc/ld.so.conf 和 /etc/ld.so.cache。

安装完成后，ffmpeg位于/opt/ffmpeg/bin目录下。

二、安装Nginx相关模块

1.环境准备

yum install pcre pcre-devel -y

yum install zlib zlib-devel -y

2.下载nginx及rtmp模块

#cd /root/soft-source/

#wget http://nginx.org/download/nginx-1.6.3.tar.gz

#tar xzvfnginx-1.6.3.tar.gz

#git clone git://github.com/arut/nginx-rtmp-module.git

3.编译nginx-rtmp

cd nginx-1.6.3

yum -y install libxml2-devel libxslt-devel

./configure --prefix=/usr/local/nginx --add-module=/root/soft-source/nginx-rtmp-module --with-http_stub_status_module --with-http_xslt_module

make

make install

安装完成后，nginx位于/usr/local/nginx/sbin目录下，配置文件nginx.conf在/usr/local/nginx/conf目录下

vi /etc/rc.d/init.d/nginx #编辑启动文件添加下面内容

复制代码

#!/bin/bash
# Tengine Startup script# processname: nginx
# chkconfig: - 85 15
# description: nginx is a World Wide Web server. It is used to serve
# pidfile: /var/run/nginx.pid
# config: /usr/local/nginx/conf/nginx.conf
nginxd=/usr/local/nginx/sbin/nginx
nginx_config=/usr/local/nginx/conf/nginx.conf
nginx_pid=/usr/local/nginx/logs/nginx.pid
RETVAL=0
prog="nginx"
# Source function library.
. /etc/rc.d/init.d/functions
# Source networking configuration.
. /etc/sysconfig/network
# Check that networking is up.
[ ${NETWORKING} = "no" ] && exit 0
[ -x $nginxd ] || exit 0
# Start nginx daemons functions.
start() {
if [ -e $nginx_pid ];then
echo "tengine already running...."
exit 1
fi
echo -n $"Starting $prog: "
daemon $nginxd -c ${nginx_config}
RETVAL=$?
echo
[ $RETVAL = 0 ] && touch /var/lock/subsys/nginx
return $RETVAL
}
# Stop nginx daemons functions.
stop() {
echo -n $"Stopping $prog: "
killproc $nginxd
RETVAL=$?
echo
[ $RETVAL = 0 ] && rm -f /var/lock/subsys/nginx /usr/local/nginx/logs/nginx.pid
}
reload() {
echo -n $"Reloading $prog: "
#kill -HUP `cat ${nginx_pid}`
killproc $nginxd -HUP
RETVAL=$?
echo
}
# See how we were called.
case "$1" in
start)
start
;;
stop)
stop
;;
reload)
reload
;;
restart)
stop
start
;;

status)
status $prog
RETVAL=$?
;;
*)
echo $"Usage: $prog {start|stop|restart|reload|status|help}"
exit 1
esac
exit $RETVAL

复制代码>

保存退出

chmod 775 /etc/rc.d/init.d/nginx   #赋予文件执行权限
chkconfig  --level 012345 nginx on   #设置开机启动
/etc/rc.d/init.d/nginx start

关闭软件防火墙：

chkconfig iptables off iptables
service iptables stop

打开网页http://localhost，如果显示Welcome表示安装下正确，如果没有显示，请查看一下nginx的日志。

++++++++测试RTMP+++++++++++

修改/usr/local/nginx/conf/nginx.conf的内容如下：

#debug

daemon off;

master_process off;


error_log ./error.log debug;

events{

worker_connections 1024;

}


rtmp{

server {

listen 1935;

chunk_size 4000;

#live

application myapp {

live on;

}

}

}

模拟测试：用ffmpeg产生一个模拟直播源，向rtmp服务器推送
/opt/ffmpeg/bin/ffmpeg -i /root/fenxiang.mp4 -c:a libfaac -ar 44100 -ab 48k -c:v libx264 -f flv rtmp://10.10.6.237/myapp/test
注意，源文件必须是H.264+AAC编码的。

10.10.6.237是运行nginx的服务器IP

下载这个软件进行测试：

VLC media player进行打开串流播放尝试。

++++++++测试HLS切片功能+++++++++++

修改/usr/local/nginx/conf/nginx.conf的内容如下：

#debug

daemon off;

master_process off;


error_log ./error.log debug;

events{

worker_connections 1024;

}


rtmp{

server {

listen 1935;

chunk_size 4000;

#live

application myapp {

live on;



hls on;

hls_path /tmp/hls;

hls_fragment 2s;

hls_playlist_length 6s;

}

}

}

#HTTP

http{

server {

listen 80;

#welcome

location / {

root html;

index index.html index.htm;

}

#hls

location /hls {

types {

application/vnd.apple.mpegusr m3u8;

video/mp2t ts;

}

root /tmp;

add_header Cache-Control no-cache;

}

location /stat {

rtmp_stat all;

allow 127.0.0.1;

}

location /nclients

{

proxy_pass http://127.0.0.1/stat;

xslt_stylesheet /root/soft-source/nginx-rtmp-module/stat.xsl app='$arg_app' name='$arg_name';

add_header Refresh "3; $request_uri";

}

}

}

使用VLC或iPAD上的播放器进行查看 http://10.10.6.237/hls/test.m3u8。 打完，收工！
