Fantastic work and loving the constant love over time.

Are there any plans to support other platforms beyond windows such as Android and / or iOS?

Just wanted to say thank you for your great library!!

I also created a webcam-capture driver for Java that might be useful for other users: https://github.com/eduramiba/webcam-capture-driver-native (I did a little change to the native proxy code to avoid high memory usage).

We use this in a production app and it works really well, clearly the best way to capture video from USB cameras on Windows, with access to device symbolink link, etc

I tried your Demo unity project (UnityVideoAndAudioRecorder) . But I couldn't get expected result. I m using Unity 2020.1. Its not even opening my web cam.

hi, I follow your code https://www.codeproject.com/Tips/1116253/Desktop-Screen-Capture-on-Windows-via-Windows-Desk
to add cursor on dxgi texture2d. but after test, it was too slow to draw the cursor,for about 6ms,,with hand cursor it
will go up to 200ms.

sample code like

         // Draw cursor image into GDI drawing texture
		 CComPtrCustom<IDXGISurface1> lIDXGISurface1;
		 hr = lGDIImage->QueryInterface(IID_PPV_ARGS(&lIDXGISurface1));
		 if (FAILED(hr))
		 	break;
		 CURSORINFO lCursorInfo = { 0 };
		 lCursorInfo.cbSize = sizeof(lCursorInfo);
		 auto lBoolres = GetCursorInfo(&lCursorInfo);
		 if (lBoolres == TRUE)
		 {
		 	if (lCursorInfo.flags == CURSOR_SHOWING)
		 	{
		 		auto lCursorPosition = lCursorInfo.ptScreenPos;
		 		auto lCursorSize = lCursorInfo.cbSize;
		 		HDC  lHDC;
                 printf("time microsecond2: %lld\n", std::chrono::duration_cast<std::chrono::microseconds>(chrono::steady_clock::now() - lastFrameTime).count());
		 		lIDXGISurface1->GetDC(FALSE, &lHDC);
		 		DrawIconEx(
		 			lHDC,
		 			lCursorPosition.x,
		 			lCursorPosition.y,
		 			lCursorInfo.hCursor,
		 			0,
		 			0,
		 			0,
		 			0,
		 			DI_NORMAL | DI_DEFAULTSIZE);
                 printf("time microsecond3: %lld\n", std::chrono::duration_cast<std::chrono::microseconds>(chrono::steady_clock::now() - lastFrameTime).count());
		 		lIDXGISurface1->ReleaseDC(nullptr);//too slow
		 	}
		 }
         printf("time microsecond4: %lld\n", std::chrono::duration_cast<std::chrono::microseconds>(chrono::steady_clock::now() - lastFrameTime).count());
        // Copy image into CPU access texture
		pCtx->CopyResource(*ppTex2D, lGDIImage);

log

time microsecond1: 19102
time microsecond2: 28896
time microsecond3: 46015
time microsecond4: 146072
time microsecond5: 287259
time microsecond1: 12035
time microsecond2: 22040
time microsecond3: 33243
time microsecond4: 124891
time microsecond5: 248231

how to solve this problem？thanks。

I don't think the APIs we currently use in the helper functions (starting with GetCursorInfo) have the ability to give us correctly-sized textures. My guess is that as it's a legacy API (Windows 2000-era), it will always recieve a 32x32 icon for compatibility reasons, and getting more modern cursors should be done with newer APIs (ie GetFramePointerShape, Windows 8+).

Tested on multiple computers with windows 10 and 11. (on developer mode)
The install.bat seems to run sucessfully allthough it complains a bit about names

Then when I try to run the application itself it displays that it is running in the taskbar and crashes

This is using the precompiled files in the Bin directory.
When trying to run it from Visual Studio Some details are given.

Any clues as to why this might be happening?

Test with WPFRecorder with ByteStreamSink and found that no video pack is being sent out.
If I add WMA audio, then only audio can be sent out but no video.

If I enable WMV8/9 CBR in CaptureManagerSDK, then both video and audio are sent out and Windows Media Player is happy.

Any idea why NetworkStreamSink fails to deliver video packs in VBR mode?

Note that if I use FileSink, both video and video look good in VBR and CBR modes.

I tried to use the python version in Python 3.8.10, after updating the code from Python 2 and Tix to tkinter. It fails however on the GUID:

On the line: self.captureManager = cc.CreateObject('{D5F07FB8-CE60-4017-B215-95C8A0DDF42A}', None, None, comtypes.automation.IDispatch)
It fails with error: OSError: [WinError -2147221164] Class not registered

It seems the GUID of the captureManager is nowhere registered. Am I missing something?

I am interested on the WPFWebViewerEVRAsync however I prefer not to use a WindowsFormsHost. Is there a way to directly output the video stream to a WPF control?

I tried to replace it with the VideoPanel class that I found on other demo but its slower than the WindowsFormsHost version.

Hello this is very nice!! is there a way to stream from the GSM devices, and can it handle any brand.

What is the discovery mechanism
Do I need special drivers for different brands or will ONVIF suffice, IP cam suffice
How to stream on an ASP web application

thansk

Can I update netcore?

The demos are difficult to understand...

Live stream does not run on VideoJS (rtmp). Runs well on Ffplay. How to overcome?

Where I can find "CaptureManagerLibrary" in project CaptureManagerToCSharpProxy.
I want to use SDK in .net 6.
Thank you!

Hello,

I am getting a 'System.AccessViolationException' when the following line from any demo project is executed:

//Line 352 CaptureManager.cs
mCaptureManager.getCollectionOfSources(ref lxmldoc);

I have the latest video drivers from nvidia, I also tried removing nvidia drivers and only use Microsoft Drivers but the problem stills there.

I don't have this problem with my laptop dell. Both machines are running Windows 11.

No useful Log information is generated, only until line "INFO_LEVEL: DMOManager: DMO is initialized!!!" and after that the Memory read/write access violation (System.AccessViolationException) is raised.

I am using the commercial versions, 1.16 and 1.19

Any help would be much appreciated,

Thanks

If I test the C# demo WPFScreenViewer and find that the delay for capturing USB camera (4K 60 FPS) is as high as 150ms, what should I do to handle this?
