  • Article

[The feature associated with this page, Microsoft TV Technologies, is a legacy feature. Microsoft strongly recommends that new code does not use this feature.]

[IEncoderAPI is no longer available for use. Instead, use ICodecAPI.]

The IsSupported method queries whether a given parameter is supported.

Syntax

HRESULT IsSupported(
  [in] const GUID *Api
);

Parameters

[in] Api

Pointer to a GUID that specifies the parameter.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code Description
S_OK
 The encoder supports the parameter.
E_NOTIMPL
 The encoder does not support the parameter.

The method returns S_OK if the encoder recognizes the GUID. To check whether the parameter can be read or modified, call the IEncoderAPI::IsAvailable method.

Any errors besides those in the table above indicate an inability to process the call.
