[SOLVED] Using libvlc.dll in VS 2005 (C++)

[bsrealm]

Hello:

1: I do not know if this is the best place to post this topic. If not, I request you to move this to the appropriate place.
2: Ok, now to my problem. I got the include/ directory from the source tarball and then copied the libvlc.dll and plugins/* to my Debug/ folder in my VC++ console application.
3: I basically copy pasted the code from http://wiki.videolan.org/LibVLC_Tutorial_086c and it compiles well but when linking, I get the following error(s):

1>------ Build started: Project: LibVLC One, Configuration: Debug Win32 ------

Please help. I have the folder in the linker additional directories too.


Thanks

Code:

#include <stdio.h>
#include <windows.h>
#include <vlc/libvlc.h>

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=.\\plugins";
char *myargs[4] = {myarg0, myarg1, myarg2, NULL};
char *filename = "B:\\Videos\\TV\\HIMYM\\Season 1\\How I Met Your Mother - 1x01 - Pilot - hdtv-lol.[VTV].avi";

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

[VLC_help]

You need a .lib file (libvlc.lib). .dll files are for runtime, .lib files are for linking. If you have libvlc.lib in right place, remember to add it to your project.

hi ;

i have same problem.. I made libvlc.lib out of libvlc.dll.. Include necessary files to VC Additional Include directory, copy all pluggin dll s and libvlc.dll just into my debugger folder.. but i am having below error

Code: Select all

1>c:\projects\vlcnew\vlcnew\include\vlc\libvlc.h(76) : error C2065: 'libvlc_exception_t' : undeclared identifier
1>c:\projects\vlcnew\vlcnew\include\vlc\libvlc.h(76) : error C2065: 'p_exception' : undeclared identifier
1>c:\projects\vlcnew\vlcnew\include\vlc\libvlc.h(76) : error C2182: 'libvlc_exception_init' : illegal use of type 'void'
1>c:\projects\vlcnew\vlcnew\include\vlc\libvlc.h(76) : fatal error C1903: unable to recover from previous error(s); stopping compilation
[/code]

I looked inside the includes and find out 'libvlc_exception_t' inside C:\pjproject-1.0-rc2\third_party\vlc\vlc-0.9.4\include\vlc\libvlc_structures.h... but it is already in my include directory.. what might be wrong ?

[VLC_help]

And that libvlc_structures.h is also included in c:\projects\vlcnew\vlcnew\include\vlc\libvlc.h ?

Can someone post some working code, what i am trying to do is a UDP pvr, i have the udp streams coming from a couple of dvb-t cards and analog cards and i want to be able to schedule a record to take place,

was going to use libVlc but cant seem to get it going becuase of the fact that a .lib does not exist

joolz

[maringer]

The problem is, as I understand, more deeper.

You can get the .libs if you rename the files ending with .dll.a in the sdk/lib/ folder (VLC > 0.9). You have to rename it from dll.a to dll.lib.

But this doesn't solve any problem. The real problem is, that in different header files is C code, which doesn't work out of the box with Visual C++ (because of memory management problems).

That is my experience at the moment.

Hello;

I am trying to use libvlc.dll in VS 2008 (C++), and I have the same problem. I have copied the libvlc.dll and plugins to my Debug/ folder in my VC++ console application. Also I have included the directories of vlc-0.9.9a (used: include, src,and libs folders).
I have used the code in the following page: http://wiki.videolan.org/LibVLC_Tutorial
When I try to compile I get the following errors:
