[PATCH] qcap: implement VfwPin_CheckMediaType(), and test connecting to a NullRenderer

[Damjan Jovanovic]

Currently a video capture device cannot even connect to a NullRenderer,
as VfwPin_CheckMediaType() always return a hardcoded E_NOTIMPL,
preventing any media format from being negotiated.

Implement it and test.
