Example
This sample shows how to programmatically add a NVIDIA Video decoder filter to a graph
string devicePath = @"@device:sw:{083863F1-70DE-11D0-BD40-00A0C911CE86}\{71E4616A-DB5E-452B-8CA5-71D9CC7805E9}";
filter = FilterGraphTools.AddFilterByDevicePath(graphBuilder, devicePath, "NVIDIA Video Decoder");
