VLC Media Player v2.0.1 is installed in the folder

Are the necessary files for adding modules located here?
c:\Program Files (x86)\VideoLAN\VLC\sdk\include\vlc\plugins
c:\Program Files (x86)\VideoLAN\VLC\sdk\libs

MinGW is installed with the gcc compiler.

A) Before attempting to create a module, this app was built based on the demo:

Code: Select all

#include <stdio.h>
#include <windows.h>
#include <vlc/vlc.h>
/*
static void quit_on_exception (libvlc_exception_t *excp) {
   if (libvlc_exception_raised (excp)) {
      fprintf(stderr, "error: %s\n", libvlc_exception_get_message(excp));
      exit(-1);
   }
}
*/

int main(int argc, char **argv) {
   //libvlc_exception_t excp;
   libvlc_instance_t *inst;
   int item;
   char *myarg0 = "-I";  char *myarg1 = "dummy";
   char *myarg2 = "--plugin-path=c:\\program files\\videolan\\plugins";
   char *myargs[4] = {myarg0, myarg1, myarg2, NULL};
   char *filename = "c:\\video\\main\\Everybody_Hates_Chris_Feb_26.mpg";

   //libvlc_exception_init (&excp);
   inst = libvlc_new (3, myargs );
   // inst = libvlc_new (3, myargs, &excp);
   //quit_on_exception (&excp);
   item = libvlc_playlist_add (inst, filename, NULL ); 
   //quit_on_exception (&excp);
   libvlc_playlist_play (inst, item, 0, NULL ); 
   // quit_on_exception (&excp);
   Sleep (10000);
   libvlc_destroy (inst);
   return 0;
}

the Makefile

Code: Select all

VLC_INST = "C:/Program files (x86)/VideoLAN/VLC"
VLC_SRC = "C:/Program files (x86)/VideoLAN/VLC/sdk"
OBJS = obj/demo.o
CC = gcc
CFLAGS = -O3 -std=c99 -D UNICODE -D _UNICODE -D _WIN32_IE=0x0500 -D WINVER=0x500 ${WARNS}
LDFLAGS = -s -lcomctl32 -Wl,--subsystem,windows

all : demo.exe

demo.exe : $(OBJS)
	$(CC) -o "$@" $(OBJS) $(LDFLAGS) -L${VLC_INST} -llibvlc -llibvlccore
#  gcc -o demo.exe demo.o
	
obj/%.o : src/%.c ${HEADERS}
	${CC} ${CFLAGS} -I${VLC_SRC}/include -c $< -o $@

The makefile indicates that the libvlc_playlist_add, and libvlc_destroy are undefined references. What is the missing library reference?

B) What are the steps to build a module, eg. decode module, on a Windows 7 x64 system.

http://wiki.videolan.org/Hacker_Guide/H ... e_a_Module
This webpage has an example stub module.
It is unclear what else is needed.
- additional code is needed to make it a DLL?
- which compiler is needed: gcc or is it possible to build a module within Visual Studio 2010

Thanks in advance.

Those functions don't exist, so no wonder it's failing.

And you need a C99 compiler, so forget MSVS already.
