JPEGLiveSource: Could not open file 'ToolkitGenericPlugin_mtd.dll or CoreToolkits.dll'!

Hello,

I have a question about the JPEGLiveSource class (MIP SDK 2019 R2 and R1). Calling the Init() method results in an exception complaining about missing files: ToolkitGenericPlugin_mtd.dll and CoreToolkits.dll.

I can see that CoreToolkits.dll is available, while ToolkitGenericPlugin_mtd.dll isn’t. According to other threads it is a legacy component, which probably should not be there.

I’ve checked the CameraStreamResolution example from the SDK. It does work in my installation. But I can’t see what is can cause the exception in my application.

Thanks in advance!

Code:

var jpegLive = new JPEGLiveSource(cameraItem);

_timeoutEvent = new Timer(TimeOutCallBack, null, 30000, 30000);

jpegLive.LiveModeStart = true;

jpegLive.Width = 0;

jpegLive.Height = 0;

jpegLive.Init();

jpegLive.LiveContentEvent += jpegLiveContentEventHandler;

_resetEvent.WaitOne();

_timeoutEvent.Dispose();

jpegLive.LiveContentEvent -= jpegLiveContentEventHandler;

Hi.

You mentioned,

>According to other threads it is a legacy component, which probably should not be there.

You are right, it should not be there. It seems that it might be mixing up. Also you may miss some dependency files. We would like to know which files are missing, so could you please show us your SDK Bin folder, such as “[C:\Program](file:C:/Program) Files\Milestone\MIPSDK\Bin”? Can you send us an image of the folder?

Hi Rie,

I’m attaching the contents of [C:\Program](file:C:/Program) Files\Milestone\MIPSDK\Bin.

Thanks!

After checking it, please tell us(or send me a screen shot) what you missed?

Thank you. I have been able to solve the problem. It had to do with DLL paths.

I had this same issue using the x86 binaries and Depends was not helpful diagnosing the issue. I simply bulk copied all of the binaries out of [C:\Program](file:C:/Program) Files (x86)\Milestone\MIPSDK\Bin in to my solution folder. Hacky but worked.
