Hello everybody... forgive my english... I'm italian XD
I need to develop an Audio Player and I'd like to import in my project vlc dll.
I put in my application folder the following files:
-axvlc.dll;
-libvlc.dll;
-libvlccore.dll.

then i added AXVLC reference.
Next I tried to add LIBVLC and LIBVLCCORE, but then appared the following error:



what can I do to resolve these problems?

I tried to work with this problem... so I created a VLCPluginClass object called canz... but when i debug the application occurs the following error:

canz.Length = 'canz.Length' threw an exception of type 'System.Runtime.InteropServices.COMException

That's normal, axvlc is an activex (or a com object), which give access to libvlc features. So you don't need to reference libvlc* in your project.

ok....what about this error?
'canz.Length' threw an exception of type 'System.Runtime.InteropServices.COMException

Why don't you use libvlcnet? Or you could use VLC with late/dynamic binding, like this: http://www.nikse.dk/libvlcdynamic.zip

ok....what about this error?
'canz.Length' threw an exception of type 'System.Runtime.InteropServices.COMException

i d'ont know abtout the activex usage, i use libvlc directly, (i use my own wrapper, something like libvlcnet).

excuse me, can you explain me what's a wrapper?
and what can I do to use libvlc directly?

a "wrapper" is a thin layer of code which translates an existing interface (libvlc's functions in our case) into a more usable interface.

What should I do to use libvlc directly? as I said in the previous post, when I try to add its reference appears an error

you can try the wrapper libvlcnet, or take a look at my source here ,and especially the videolan.interop part (it's a vlc wrapper lib, based on kairos one, but modified for my needs).

Where I have to click do download them?

libvlcnet: google a little, and you'll find this : http://sourceforge.net/projects/libvlcnet/
my sources : there is a snapshot link above the file list.

I already have this .zip, but when I try to add libvlc to my project appears the error that I said in the previous post...
the problem is that I don't know how resolve it

it's because you can't add libvlc.dll or libvlccore.dll in your project. Just use it directly, see libvlcnet or my code for that.

excuse me... can you tell me precisely how can I use libvlc directly?
I took your source but there was nothing about libvlc.dll

Of course there is, look for DllImport("libvlc") in VideoLan.Interop/InteropMethods.cs.
All libvlc functions/structures/enums are declared in this file.

thanks
i saw libvlc methodes, but i can't find libvlc classes...
if I want to instantiate a song object, what should I do?

there are no libvlc classes ...

what is a "song object" ?!?!?

I used wmpLib and then there is a class called WindowsMediaPlayerClass that allows you to manage the trasmission of a song.
i need a class like that in libvlc

There are no such things in libvlc, only methods.
You can use the methods directly, or use a wrapper (mine, libvlcnet, ....) which is just a few classes which allows a more object approach.

There are a lot of documentations and example, for instance http://wiki.videolan.org/Libvlc, http://wiki.videolan.org/LibVLC_Tutorial, or http://wiki.videolan.org/C_Sharp

Read them.
