[gst-devel] gst directshow wrapper weirdness

[Sébastien Moutte]

if you still have the same error code saying that it can't find the fake 
sink's CLSID in the registry, you should search for 
{6A780808-9725-4d0b-8695-A4DD8D210773} key in your registry to check if 
the filter object registration was done correctly or not.
Normally, you will find a key 
HKEY_CLASSES_ROOT\CLSID\{6A780808-9725-4D0B-8695-A4DD8D210773} with the 
path of DLL in as default value of InprocServer32 subkey.
