安装 crtmpserver服务
sudo aptitude install crtmpserver
添加 crtmpserver日志文件
sudo mkdir /var/log/crtmpserver
配置crtmpserver服务环境
sudo nano /etc/crtmpserver/applications/flvplayback.lua
修改以下几行 保存退出
validateHandshake=false,
keyframeSeek=false,
seekGranularity=0.1
clientSideBuffer=30
重启 crtmpserver 服务
sudo /etc/init.d/crtmpserver restart
安装编译 ffmpeg ，系统的ffmpeg自带的不支持H264编码的flash 流，需要下载支持的ffmpeg编译，这个部分编译时间比较长，也是重要的一个步骤。
sudo aptitude remove ffmpeg
cd /usr/src
sudo mkdir ffmpeg
sudo chown `whoami`:users ffmpeg
git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
cd ffmpeg
./configure
make
sudo make install
我编译好的包 http://urlxf.qq.com/?j6feUrQ ，下载解压到 可以省很多时间
sudo make install
实现摄像头数据转实现RTMP，官方时间用-1有错误提示，下面更正了

for outside (internet), you need to open port 1935 and 80 to your RPi
if you have two or more cameras, only one can be accessed from internet :(
