[gst-devel] Question on dshowvideodec

Normally Dshow fake filters are registered by calling 
gst_dshow_register_fakefilters at decoder plugin initialization.
If it doesn't work, it could be because you don't have administration 
rights or you are using Vista with UAC.
DirectShow filters need administration rights to be registered so I will 
register them in the setup installers and application using them will 
have to register them at installation time.

You can try to run regsvr32 $PATH/libdshow.dll to register them so you 
will see if there is an error returned or UAC prompted.
