Topic: On Trial Version Attempting to Make Plugin
Good Afternoon y'all, I downloaded VirtualDJ as I seen there was an Dsp SDK for it. I have already made/compiled a DLL file, I have done numerous revisions, no matter what I cann't get VirtualDJ to handshake with the DLL file.

I do not know if this is an issue because I am on the Trial, but everything I seen says the Trial version should be able to load while I have Pro features. I've tried installing it in numerous different folders/directories that I have found on this forum/reddit. I just can't get the thing to hand shake.

I installed VirtualDJ to D:\VirtualDJ I have put Plugins/Pluginsx64 there, my documents folder, I'm not sure if its a Trial issue or directory issue.

Any help would be appreciated.

Do you use "IID_IVdjPluginBasic8" ?

We are going to move this topic in the plugins section of this forum
 
extern "C" VDJ_EXPORT HRESULT VDJ_API DllGetClassObject(
    const GUID & rclsid,
    const GUID & riid,
    void** ppObject)
{
    if (!ppObject) return E_POINTER;
    *ppObject = nullptr;

    LogLine("[DllGetClassObject] called");

    if (rclsid == CLSID_VdjPlugin8)
    {
        if (riid == IID_IVdjPluginDsp8 || riid == IID_IVdjPluginBasic8)
        {
            LogLine("[DllGetClassObject] providing CohraTelemetry instance");
            *ppObject = new CohraTelemetry();
            return S_OK;
        }

        LogLine("[DllGetClassObject] CLSID ok, but riid not matched");
    }
    else
    {
        LogLine("[DllGetClassObject] rclsid not CLSID_VdjPlugin8");
    }

    return E_NOINTERFACE;
}
 
I've found a couple of different examples, there was one on this form that was something like running dll on PC or something, as far I can tell the hand shake should be happening.
 
Try with "IID_IVdjPluginDsp8" only.

class CMyplugin : public IVdjPluginDsp8

And compile in 64bit

C:\Users\{your_username}\AppData\Local\VirtualDJ\Plugins64\SoundEffect\myplugin.dll

Here is an exemple:

Do you use an external library in your code that could prevent the dll from being loading?
 
Yes, I am using Winsock2 for UDP telemetry. Other than that I am only using standard libraries like cmath and cstdio and the SDK headers
 
BOOM, YOU NAILED IT!!!

I retried it with your code and put it in the AppData folder and that did it, appreciate you!!!!
