URL = "http://192.168.233.129:8000/camera/mjpeg
camera - Is it camera name?

Camera URL.

When debug code as in video I get message: "You can see this window because OnError event is not implemented in your code. Implement OnError event to see errors, create empty handler to ignore all errors.
Unable to create LAV Splitter Source filter. Please be sure that LAV filters installed.
Unable to open IP camera stream. Please check URL. Remember, you're need direct video URL, not just IP address."

Please install SDK from product page or add the following NuGet packages: VisioForge.DotNet.VideoCapture.TRIAL, VisioForge.DotNet.Core.Redist.VideoCapture.x64, VisioForge.DotNet.Core.Redist.LAV.x64.

I've installed NuGet packages: VisioForge.DotNet.VideoCapture.TRIAL, VisioForge.DotNet.Core.Redist.VideoCapture.x64, VisioForge.DotNet.Core.Redist.LAV.x64. But I have error: Unable to create filter: LAV Splitter Source

What does this mean?

If your app started as x64 that should work. For x86 app you can add x86 NuGet packages.

videoCapture lose from tools

videoCapture lose from tools

What do you mean?

I have x64 Windows and this program doesn't work

May be that is because I have login and password but I don't know where them to insert in code

Yes, if your camera require login/password.

Login/password can be set in videoCapture1.IP_Camera_Source property.

Please check https://github.com/visioforge/.Net-SDK-s-samples/tree/master/Video%20Capture%20SDK/WinForms/CSharp/IP%20Capture demo.
