Hi,

I know I can retrieve an interface to the 1st added video processor of a capture control by calling the GetSubObject method with CaptureObject.SelVideoProcessor as the parameter.

But if i have 2 or more filters/processors active at a time how can I retrieve interfaces to the others?

The only way i know of is through GetSubObject, and none of the CaptureObject enum values seem to what I'm looking for.

Am i missing something obvious? Any help would be greatly appreciated. By the way, I'm doing this in C# using mm sdk v17 .

Thanks,

Tony.

Tony,
To select the first object, you pass (CaptureObject.SelVideoProcessor) to the function.
To select any other object (index from 1 to N-1), you pass (CaptureObject.SelVideoProcessor + index).

This means if you have 4 processor filters selected into the control, and you want to get the last processor, you pass (CaptureObject.SelVideoProcessor + 3).

Thanks,
