• • socks=host:port
  • app=name
  • tcUrl=url
  • pageUrl=url
  • swfUrl=url
  • flashVer=version
  • conn=type:data
    • Append arbitrary AMF data to the Connect message. The type must be B for Boolean, N for number, S for string, O for object, or Z for null. For Booleans the data must be either 0 or 1 for FALSE or TRUE, respectively. Likewise for Objects the data must be 0 or 1 to end or begin an object, respectively. Data items in subobjects may be named, by prefixing the type with 'N' and specifying the name before the value, e.g. NB:myFlag:1. This option may be used multiple times to construct arbitrary AMF sequences. E.g.
  • conn=B:1 conn=S:authMe conn=O:1 conn=NN:code:1.23 conn=NS:flag:ok conn=O:0

installation

Linux

* on CentOS: http://wiki.rtmpd.com/tutorial_full_centos_build

• I choose /opt/crtmpserver as source directory

svn co --username anonymous https://svn.rtmpd.com/crtmpserver/branches/1.0 crtmpserver

• do compile the source specifying the prefix you want, /usr/local is a good choice to keep the file-system under control, but remember to check the $PATH variable afterwards:

cd builders/cmake
cmake -DCRTMPSERVER_INSTALL_PREFIX=/usr/local .
make install

• now let's go in /usr/local/etc/ and use crtmpserver.lua.sample to generate your crtmpserver.lua changing the rootDirectory=" variable in applications= { /usr/local/lib/crtmpserver/applications

• install the certificates:

cp /usr/src/crtmpserver-690/builders/cmake/applications/appselector/server.* /usr/local/lib/crtmpserver/applications/appselector/

• link your own media directory (in this case I'm linking the Videos directory located in my home) to the player application media foder:

ln -s ~/Videos /usr/local/lib/crtmpserver/applications/flvplayback/mediaFolder
cp /usr/src/crtmpserver-690/builders/cmake/applications/flvplayback/users.lua /usr/local/lib/crtmpserver/applications/flvplayback/

• it should be possible now to execute the compiled and configured program

configuration

• /opt/crtpmserver/configs

all.debug.lua
flvplayback.lua
run.bat
run.sh
users.lua

apps

• flash streamer application

/opt/crtpmserver/configs/flvplayback.lua

applications

• application files:
