WINCODEC_ERR_NOTINITIALIZED

WINCODEC_ERR_NOTINITIALIZED means that a WIC component was used before the initialization required by that interface completed. WIC decoders, encoders, transforms and streams have separate initialization methods; constructing a COM object alone is not enough.

What to check

Check the HRESULT from the component's Initialize method before using any dependent method.
Ensure that the stream, bitmap source, frame or option object passed to initialization remains valid for the lifetime required by the component.
Do not continue after a failed initialization only because an output interface pointer is non-null.

The first failed call is generally more useful than this later lifecycle error.
