DirectShow.NET Guru Webcam Mini-Project to help my C# program

Hi I'm Ned in Redmond, Washington USA. My C# .NET 4 application uses any webcam as a motion detector, but it has some stability issues that we've traced to a known Windows bug. So, The answer is fix the problems by use DirectShow.NET. Please code the following in DirectX for me: 1. Stop and Start a webcam 2. Motion capture every 100 miliseconds and save to disk 3. Choose between different webcams on the fly as the code is running. More specifically: * I need something written form scratch and that will use DirectShow * I can't use any 3rd party application or open source code if it will require me to reveal my code (that may be part of GNU license). * I need this to capture motion detection with adjustable sensitivity ("We'll give it as a parameter in this function:bool StartMonitoring (NameOfWebCamToUse, EventNameToSignalIfMotionDetected, SensitivityIn1to100Range) * It must be a stand alone component that will have these functions: - string [] GetListOfInstalledWebCamsWhichAren'tInUse - bool StartMonitoring (NameOfWebCamToUse, EventNameToSignalIfMotionDetected, SensitivityIn1to100Range) - bool StopMonitoring (If these 3 functions work reliably, we are all set. This is the only problem we currently have in our app: Once we stop, we can't restart without crashing because of a bug in Windows.) * Code should be able to handle multiple stop/start sequences in the same process. * I need the source code, not just the binary Thanks, Ned
