Signed-off-by: Zebediah Figura z.figura12@gmail.com --- A devenum device comes in one of four types: DirectShow filter, DMO, audio or video codec, or PNP device. Each of these is identified in a slightly different way.
* A DirectShow filter (sw) is identified by a subkey under the CLSID key. They're normally registered through IFilterMapper2:RegisterFilter. devenum doesn't touch these keys, but rather just reads from them; it translates every key/value pair directly into an IPropertyBag property.
* An audio or video codec (cm) is identified by a subkey under the HKCU\Software\Microsoft\ActiveMovie\devenum key. This key is populated by devenum from a variety of sources, including the "legacy" HKCR\Filters key and the Drivers32 key. After being populated, it's read in the same way as the DirectShow filters above.
* A DMO (dmo) is identified by its CLSID and its category GUID, in that order. These aren't read in the same way as the above; rather, the key/value pairs are translated from the DMO storage format into the devenum format.
* A PNP device (pnp) is identified by a path in the global namespace, i.e. beginning with '\?'. devenum read these from the registry at the path CurrentControlSet\Control\DeviceClasses{category guid}##?#Root#SYSTEM#0000#{category guid}, and the properties for the IPropertyBag are given by the subkey "Device Parameters".
Previously, the code treated filters as "normal" and codecs as "special", and assumed the difference lay in which category a device was registered under. As the tests show, however, devenum will enumerate all of the available device types for any given category.
v2: fix test failures.
