DirectShow is one option. You may use Sample Grabberfilter to build FilterGraph and grab first frame. http://msdn.microsoft.com/en-us/library/dd407288(VS.85).aspx
Otherwise, using VMR filter, IVMRWindowlessControl9::GetCurrentImage Method will also do it.
Scale the frame to thumbnail of desired size, GDI+ is the simple option for this.
