c# issue with vlc libraries

[microprocessore]

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.

[microprocessore]

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?

[XilasZ]

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

[XilasZ]

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).

[microprocessore]

Where I have to click do download them?

[XilasZ]

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.

[microprocessore]

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

[XilasZ]

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.

[microprocessore]

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

[XilasZ]

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

[microprocessore]

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

[XilasZ]

there are no libvlc classes ...

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

[microprocessore]

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

[XilasZ]

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.
