The XySubFilterAutoLoader dummy input pin is indeed unnamed, but you'll need to
explain what he is trying to do which makes this an issue.

I checked with bLight. Initially, he was not able to get xysubfilter to work,
due to the missing pin name (I assume this is how Zoom connects to the older
xyvsfilter). He has now used the manual version of xysubfilter, which now
allows Zoom to load xysubfilter. He said that with regards to the pin name, he
was trying to make sure he connected to the right pin if in the future
xysubfilter decides to add additional pins for other functionality.

Strictly speaking, XySubFilterAutoLoader should not be used for manual graph
building.
It is a helper filter only, with the sole purpose of deciding whether or not to
load XySubFilter into the graph (and unload VSFilter). This unnamed 'dummy
input pin' is a special pin which rejects all connections by design. When 'Load
When Needed' is enabled, this dummy pin is also used to spy on the MEDIATYPE of
connection attempts. Reference:

Check with Blight, but I think it would make sense to leave things how they
are, with only 'real' connectable pins given the standard names of 'Input' &
'Output' now and in the future? Though if he disagrees and would still prefer
it be named anyway, we could certainly make that change in the next release.
That said, for DirectShow itself the pin name is purely cosmetic. The real
value which matters for determining type is PIN_DIRECTION (

Thanks, I pointed him to your post. I think he is satisfied where things stand
at the moment, and he is happy for the report to be closed.
