VFW_E_TYPE_NOT_ACCEPTED

VFW_E_TYPE_NOT_ACCEPTED is a DirectShow HRESULT. The proposed media type is structurally valid, but this particular pin cannot process it. The pin may support a narrower set of codecs, pixel formats, sample rates or format details than the upstream filter offered.

How to diagnose it

Use media-type enumeration and QueryAccept to identify the first accepted type.
Compare the complete format block, not only the major type and subtype.
Insert a converter, decoder, resampler or color-space transform when the source cannot produce an accepted type directly.

This differs from VFW_E_INVALIDMEDIATYPE: the type can be valid but unsupported by the specific pin.
