I'm trying to programmatically control the rotate filter.
I can add the filter in my filter graph, and everything is fine.
Yet I don't know how to acces its properties. Indeed I can't QueryInterface the filter to get the ISettingsInterface, since I don't have its clsid or .h or .idl (haven't found it on web or msdn).
BTW, I'm a beginner @ COM stuff... :)
The clsid IID_ISettingsInterface is defined in https://sourceforge.net/p/videoprocessing/code/HEAD/tree/trunk/videoprocessing/Source/RtvcLib/DirectShow/SettingsInterface.h
So if you've downloaded the source you can find it under videoprocessing/Source/RtvcLib/DirectShow/SettingsInterface.h
Otherwise you can just copy the GUID into your source code.
Hope that helps,
Sure it helps!
I shoud have checked in the source code :)
