GraphEdit only works for DirectShow, and not for topologies built using MediaFoundation.
Is there a similar tool as GraphEdit for MediaFoundation?
Similarly to GraphEdit, TopoEdit is a visual tool for building and testing MediaFoundation topologies.
TopoEdit is available in the Windows SDK, starting with the Windows SDK for Windows Server 2008 (remember to tick Tools checkbox).
By default it installs to: C:\Program Files\Microsoft SDKs\Windows\v7.1\Bin
