luac | lua bytecode format that grew to be the luac command line

So what happened is that the library in Debian providing support for live555 was removed in February of this year, this affects all downstream distros including but not limited to RPi OS and Ubuntu:

https://askubuntu.com/a/1363113

The 2 active versions were 2020.01.19-1 and 2018.11.26-1.1, Live555 has since added GPL license headers to the offending files, however the RFC issue remains.

Now you may be tempted to just download the latest Live555 source code and compile it... it does not work. There have been changes to function names and structures referenced by VLC, and as such VLC will not compile against the source. You need to get an older version, I specifically used this one, which is a tweaked snapshot from 2020 prior to the modifications that prevent VLC compilation:

https://github.com/rgaufman/live555

The configuration you want is ./genMakefiles linux-with-shared-libraries, I do not know if it is required but since my system is x86-64-bit I added -m64 to the compiler options first

After compilation and install, I went on to compile VLC, adding '--enable-live555' and '--with-live555-tree=extras/live555-master' after placing the root Live555 folder in the VLC extras folder, however VLC failed to compile, it turns out the Live555's make install does not copy all the header files needed to where VLC is looking. They were dropped as 4 subfolders into /usr/local/include/, and the actual libs into /usr/local/lib/. Adding the correct CXX/CPP flags will make it look where they were put, however I put them all in a single folder and used 1 flag.

I also had to '--disable-mod' to work around a dependency version issue that I had no interest in fixing, since I do not use modplug or any mod files.

50 minutes later... VLC successfully compiled! However it was expecting the libraries for Live555 to be in /usr/lib/ not /usr/local/lib/, since it took so long to compile I was just fine with linking or copying the libraries into the expected folder, and after that VLC works with RTSP when linked to the new file. Or you can choose to maintain the original VLC and run the new file directly if you need to load the camera feeds.

Turned out that I had to use lua51 dll provided by Noita and the correct headers related to Noitas luaJit used version 2.0.4.

For everyone stumbling about this, this is how I build the enet.dll

Your code is C++ but the Lua library exports a C API.

Put the Lua includes inside extern "C" {...} or include lua.hpp instead.

Also, you need to put -llua at the end of the command line:

What confused me was that it worked in the lua console but not in my program. I added a call to lua_tostring after the call to luaL_dofile, like this:

You're looping over all lines, which includes an empty line. Here's a solution:

Stock Lua does not compile the bytecode into assembly code, it has a bytecode execution engine, the Lua virtual machine. So

lua_topointer returns a pointer to a lua object. You just want to use lua_tonumber instead.

Note that a number is normally a double so will not be able to hold 64-bit addresses, in your example it should work though as the address appears to be 32-bit.
