About lua plans
Alex
I am trying to learn internals and usage of rtmpd. I would like to
achieve the Lua application for rtmpd server. Does this make sence ?
As I understand the intended way is to create new project for
application that will produce shared object/dll and then add its usage
to crtmpserver.cpp.
What do You think about using LuaJIT2 and its FFI feature (http://
luajit.org/ext_ffi.html) to interface crtmpserver ? Actualy to
implement `crtmpserver.cpp` in Lua code and import all parts needed
from `thelib` by FFI declarations.

Let me ask question: for what need LUA JIT in real-time media server?
What overkill feature it provide?

Main reason is integration with other software modules that are
written in Lua and Python. To avoid rewriting application and data
management logic.

Based on that, Lua will become dynamic language used in crtmpserver
more than just to parse config table.
It would be nice to know planned improvements.
C++ RTMP Server
Lua is already integrated as a scripting language inside crtmpserver. The interface is not as complete as I wanted it to be, but has the basics and can be useful. If more functionality is needed, it can be easily added by looking at the existing one as an example. It works quite nice.
The main reason for not using lua the other way around (host C inside lua) is that crtmpserver is a C++ application and has a lot of C++ specific things, especially classes (objects). So, for it to work nice, one should wrap all classes and make them available to lua. While this is perfectly doable, I prefer doing the other way around because not all languages supports this. That's the reason for hosting a "virtual machine" inside crtmpserver. This "virtual machine" has all the bits and pieces necessary for hosting an external language inside c++ runtime.
Cheers,
Andrei
