I reference the project in_mplayer(http://sourceforge.net/projects/inmplayer),
which can compile mplayer as a single dll under mingw compile environment.
and i follow it's instructions, but failed. so, i write my own Makefile,
it's content listed below.

i modified file "mplayer.h", and "#define DISABLE_MAIN" at end of file, and
save it.
i do those commands in mingw/msys environment
$./configure --disable-debug --disable-mencoder --disable-sdl
--disable-pthreads --enable-w32threads
$make
$make -f Makefile_dll
then i got a single dll file, i wrote test code like below:
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include "stream/stream.h"
#include "libmpdemux/demuxer.h"
#include "libmpdemux/stheader.h"
int main(int argc, char* argv[])
{
stream_t* stream = NULL;
demuxer_t* demuxer = NULL;
char* filename = "d:\\Music\\01.mp3";
int file_format = 0;
sh_audio_t *sh_audio = NULL;
sh_video_t *sh_video = NULL;
demux_stream_t *d_audio = NULL;
demux_stream_t *d_video = NULL;
HMODULE hModule = LoadLibrary("mplayer.dll");
if(hModule)
{
typedef void* (*open_stream)(char* filename,char** options,int*
file_format);
typedef void* (*demux_open)(void *stream,int file_format,int aid,int
vid,int sid,char* filename);
open_stream _open_stream = (open_stream)GetProcAddress(hModule,
"exp_open_stream");
demux_open _demux_open = (demux_open)GetProcAddress(hModule,
"exp_demux_open");
printf("%p %p\n", _open_stream, _demux_open);
stream = (stream_t*)_open_stream(filename, 0, &file_format);
demuxer = (demuxer_t*)_demux_open(stream, file_format, -1, -1, -1,
filename);
d_audio=demuxer->audio;
d_video=demuxer->video;
if(d_audio)
sh_audio=d_audio->sh;
printf("stream=%p, demuxer=%p, d_audio=%p, d_video=%p, sh_audio=%p\n",
stream, demuxer, d_audio, d_video, sh_audio);
FreeLibrary(hModule);
}
return 0;
}
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
when i run test code, the result displaied is not right, d_audio always is
NULL, but use gdb debug mplayer.exe, which is not NULL. is someone could
help me?
and i attached Makefile what i created in a attachment.
best regards,
jacky_zz
