We've found that Windows Server 2008 SP2 doesn't contain QEDIT.DLL.
This 'DirectShow Editing' DLL contained several useful DirectShow filters, namely SampleGrabber, that we had been using.
I found some references to this issue during the Windows Server 2008 beta cycle, but it was supposed to have been added back for release.
Does anyone have any current knowledge of this, and if there are any workarounds other than copying a version from Vista or Win2003?
The SampleGrabber filter is one of the MSDN sample filters. I'm not sure whether all the filters that you need are available as samples though.
