I compiled an (existing [1]) directshow source filter, then plugged it into VLC to use it and get this:

dshow error: couldn’t bind moniker to filter object (0x800401f9)

dshow error: can’t use device: Virtual Cam, unsupported device type

compiled using visual studio 2010 express + windows SDK 7.1

any ideas out there?

[1] original was “capture source filter” from http://tmhare.mvps.org/downloads.htm and his binaries actually register and work right (well, they at least start right, then they hang VLC but that’s a different story).

    Once I created a def file with the right methods and instructed the linker to use it it works now.

    Happy day.
