如何搭建一个属于自己的直播平台 编译问题总结

1. 如何搭建一个属于自己的直播平台 参考 http://www.open-open.com/lib/view/open1473231814360.html
nginx.conf 配置如下，

#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 {
worker_connections  1024;
}

rtmp {
server {
listen 1935;
chunk_size 4000;

# HLS
application hls {
live on;
hls on;
hls_path /tmp/hls;
}

# MPEG-DASH is similar to HLS
application dash {
live on;
dash on;
dash_path /tmp/dash;
}
}
}

# HTTP can be used for accessing RTMP stats
http {

server {
listen      8080;

#location / {
#    index index.html;
#    root /usr/local/nginx/html;
#}

# This URL provides RTMP statistics in XML
#location /stat {
#rtmp_stat all;
# Use this stylesheet to view XML as web page
# in browser
#rtmp_stat_stylesheet stat.xsl;
#}

#location /stat.xsl {
# XML stylesheet to view RTMP stats.
# Copy stat.xsl wherever you want
# and put the full directory path here
#root /path/to/stat.xsl/;
#}

location /hls {
# Serve HLS fragments
types {
application/vnd.apple.mpegurl m3u8;
video/mp2t ts;
}
root /tmp;
add_header Cache-Control no-cache;
}

location /dash {
# Serve DASH fragments
root /tmp;
add_header Cache-Control no-cache;
}
}
}

player.html里面，改为  newplayer({"stream_url": "hls/life.m3u8","poster":"hls/poster.jpg"});  这样就可以直播 hls里面的m3u8文件了，http://localhost:8080/player.html

2. nginx build on cygwin

运行时出现"the maximum number of files supported by select() is 64", 问题解决参考http://powertech.iteye.com/blog/2126745

这表示FD_SETSIZE的值比nginx配置文件中worker_connections指令所指定的值，加了--with-cc-opt=”-D FD_SETSIZE=4096”后就不会碰到这问题

3. ffmpeg build

build过程参考http://blog.csdn.net/zmlcool/article/details/8141097

a. Builing ffmpeg with libx264 enabled on cygwin， 参考http://stackoverflow.com/questions/4779040/builing-ffmpeg-with-libx264-enabled-on-cygwin

加上 --extra-ldflags="-L /usr/local/lib"， 在运行configure的时候。

./configure --extra-ldflags="-L /usr/local/lib" --enable-libx264 --enable-libmp3lame --enable-libfaac --enable-gpl --enable-nonfree

b. build mp3lame

configure: error: cannot guess build type; you must specify one

解决办法：http://stackoverflow.com/questions/4810996/how-to-resolve-configure-guessing-build-type-failure

search for /usr/share/automake*/config.guess

check the latest version of automake

$ which automake

$ automake --version

find the appropriate automake folder in /usr/share/automake.1.11.1/config.guess

replace config.guess from your build tree with /usr/share/automake.1.11.1/config.guess

(The same may/is usually needed for config.sub.)
