Forum: VirtualDJ Plugins

Topic: Plugins - Sources Codes or/and Beta Version - Let your links or ideas here con't

This topic is old and might contain outdated or incorrect information.

My idea is to create a VirtualDJ Output Plugin that dynamicly updates an Extended .m3u file or something like this....

#EXTM3U
#EXTINF:111,3rd Bass - Al z A-B-Cee z
mp3/3rd Bass/3rd bass - Al z A-B-Cee z.mp3

1st line remains unchnaged
2nd line #EXTINF:<lenth of song in second>,<Artist - Title>
3rd line is the filename of the mp3
in this example c:\\mp3\\3rd Bass\\3rd bass - Al z A-B-Cee z.mp3

The plugin will query the function GetInfo() and to get the info we need (length of song in seconds,artist,title,file path) and have the plugin take the acquired information and write an M3U with this info

Here are the parameters from GetInfo() for what we need
1.Length of Song in Seconds: SongLength(int*): returns the length in samples of the actual song (in 1/44100th seconds)
2.Artist: Author(char*): return the author of the actual song.
3.Title: Title(char*): return the title of the actual song.
4.Path: FileName(char*): return the filename of the actual song.

If someone will write an .dll (in C++) that can get this info I will do the rest.

Thank You

I have just corrected the needs of your project

Ok Thank You, am I to understand that the outcome (the plugin) will be a DLL that Query's a DLL?

NO no, you don't use getinfo.dll

Forgive my Ignorance again....but if the plugin doesn't use GETINFO.DLL, why does it exist? Does it not act as a conduit between VDJ and the plugin?
Sorry :(

Why am I getting the following compiler errors in VC++ 2003 with the VDJ4~ SDK?

Compiling...
my_plugin1.cpp
my_plugin1.cpp(16) : error C2518: keyword 'class' illegal in base class list; ignored
my_plugin1.cpp(16) : error C2499: 'Cmy_plugin1' : a class cannot be its own base class
my_plugin1.cpp(16) : error C2059: syntax error : ':'
my_plugin1.cpp(17) : error C2518: keyword 'class' illegal in base class list; ignored
my_plugin1.cpp(18) : error C2518: keyword 'class' illegal in base class list; ignored

But I don't get those errors when Compiling the VdjDspWizard.exe

So - to answer the getinfo.dll question - there is no DLL called getinfo. As you state in your own blog the GetInfo() is a method of the VirtualDJ environment that you can use to retrieve info about the VirtualDJ environment.

Second - give you error message and not showing the code you are trying to compile doesn't help. Need to see the code.

In regards to the first question located in the SDK there is a file called http://ethan-hines.110mb.com/GetInfo.dll

You have just copied plugin.cpp without considering the type of plugin you use
=> It's syntax of the wizard for Visual Studio
[!if xxxxxxx] ... [!endif]

Is this the function to get info from VDJ? It was located in VdjDsp2.h
HRESULT (__stdcall *GetParam)(int desk,char *param,void *result);
at the bottom of that h file were the params:
Params list:
- Bpm (float)
- Pitch (int)
- FilePath (char*)
- FileName (char*)
- FileSize (int)
- Author (char*)
- Title (char*)
- SongLength (int)
- Volume (int)
- Comment (char*)
- PlayPos (int)
- VdjFolder (char*)
- EffectFolder (char*)
- VdjVersion (int)
- CurrentDesk (int)
- CurrentSlot (int)
- CrossfaderVolume (int)
- Crossfader (int)

I assume (int) means integer and (char*) means contains characters.

Also in the previous code there are codes that say "delete this'" am I to delete that line or is this valid code?

Ok, break, you are totally wrong since the beginning:

1) Download the last SDK in the tools section of the website: the one for VirtualDJ v4.x and not the old SDK and don't mix the files between them.
2) create a dll project with vdjplugin.h and plugin.cpp
3) Use my basis code instead of the code written in the plugin.cpp of the SDK

e:Microsoft Visual Studio .NET 2003Vc7vcprojectsSDK for VirtualDJ v4.x and Numark CUEpluginsdkVdjPlugin.h(93) : error C2375: 'DllGetClassObject' : redefinition; different linkage
e:Microsoft Visual Studio .NET 2003Vc7PlatformSDKIncludeObjBase.h(807) : see declaration of 'DllGetClassObject'

which sends me inside VdjPlugin.h to:
__declspec( dllexport ) HRESULT __stdcall DllGetClassObject(const GUID &rclsid,const GUID &riid,void** ppObject);

With the old SDK (VdjDspWizard.exe) there was a wizzard and it was writen in VC++
The New SDK (SDK for VirtualDJ v4.x and Numark CUE) I think was writen in plain C

Here's a zip of the VC++ 2003 project http://ca.briefcase.yahoo.com/ethanhines

When you release source codes, only add the important files because your package is 4.47MB ;-)

I mean you can delete the .ncb file and the release or debug folder

Ok first you used MFC whereas it's useless:

select this for "Use of MFC":
"Use Standard Windows Libraries"


Then create an empty dll project
(stdafx.h and stdafx.cpp are for MFC)
 
Posted Wed 18 Apr 07 @ 6:06 pm
Ok I Deleted all that other stuff I used standard libraries and I still am getting error
error C2375: 'DllGetClassObject' : redefinition; different linkage
and
ObjBase.h (807) : see declaration of 'DllGetClassObject'

locatedin VdjPlugin.h at line 93
