| Values | 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.
