Unable to enumerate any media types on my filter's pins

[Rednahc]

I am in the process of developing a H.264 video encoder filter. I have added
the following registry entries in filter project's .reg file:

[HKEY_CLASSES_ROOT\Filter\{B2E82896-5BD7-4299-B65D-8F95A011A2E7}]

In a test application, I create an instance of this filter and when I try to
enumerate the pins and the supported media types, I see the following issues.

1. QueryPinInfo returns the name "XForm In" on the input pin and "Xform Out"
on the output pin instead of "Input" and "Output".

2. Enumeration for supported media types on the pins fail without returning
even a single AM_MEDIA_TYPE structure.

Pleae help!

The registration info should *not* be added directly to the
registry but through IFilterMapper2::RegisterFilter() or
AMovieDllRegisterServer2().

1. QueryPinInfo returns the name "XForm In" on the input
pin and "Xform Out" on the output pin instead of "Input"
and "Output".

The filter returns what's specified in the code, not what's
in the registry. It's up to you to make the 2 sets of
informations match (including the media types). The set in
the registry is only used by IntelligentConnect to decide
which filters to try, but then it's up to actual filter code
to make final decisions.

Did you add the filter to a graph? Filters are not designed
to work outside a graph (even though sometimes certain
methods do).
