IEncoderAPI::IsSupported

Note   The IEncoderAPI interface is deprecated. Use ICodecAPI instead.

The IsSupported method queries whether a given parameter is supported.

Syntax

HRESULT IsSupported(
  const GUID* Api
);

Parameters

Api

[in]  Pointer to a GUID that specifies the parameter.

Return Values

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

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

Remarks

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.
