ENCODER INTERFACES NVGetCodec Description: Syntax: Parameter: Return Value: Remarks: Get the current encoding format HRESULT __stdcall NVGetCodec (NVEncoder hNVEncoder, DWORD *pdwCodecType) hNVEncoder [in] Handle to the encoder instance pdwCodecType [out] Pointer to store the current encoding format S_OK: Successful E_FAIL: The encoding format is not initialized E_POINTER: pdwCodecType is NULL pointer/ encoder handle is invalid If successful, *pdwCodecType stores the current encoding format NVIsSupportedParam Description: Syntax: Parameter: Return Value: Query if the parameter type is supported HRESULT __stdcall NVIsSupportedParam(NVEncoder hNVEncoder, DWORD dwParamType) hNVEncoder [in] Handle to the encoder instance dwParamType [in] Parameter support to query S_OK: The parameter is supported E_FAIL: The parameter is not supported E_POINTER : Encoder handle is invalid Remarks: Parameter types are listed in Encoder Parameters on page 25 NVIDIA CUDA VIDEO ENCODER SP04456-001_v03 | 18
ENCODER INTERFACES NVSetParamValue Description: Syntax: Parameter: Return Value: Set the value of the specified parameter type. The pData points to a memory region storing the value of the parameter. The parameter can be a data structure, which must match the size of the parameter type. HRESULT __stdcall NVSetParamValue(NVEncoder hNVEncoder, DWORD dwParamType, LPVOID pData) hNVEncoder [in] Handle to the encoder instance dwParamType [in] Parameter to set pData [in] This pointer points to memory storing the value(s) of the parameter S_OK: Successful E_FAIL: Fail to set the value (e.g. encoder state does not allow) E_NOTIMPL: Parameter is not adjustable E_UNEXPECTED: The encoding format is not initialized yet. E_POINTER: pData is NULL pointer/ encoder handle is invalid Remarks: Parameter types are listed in Encoder Parameters on page 25 NVGetParamValue Description: Syntax: Parameter: Return Value: Remarks: Query the current value of the specified parameter type HRESULT __stdcall NVGetParamValue(NVEncoder hNVEncoder, DWORD dwParamType, LPVOID pData) hNVEncoder [in] Handle to the encoder instance dwParamType [in] Parameter to query pData [out] This pointer points to memory to store the value(s) of the parameter S_OK: Successful E_NOTIMPL: The parameter is not supported E_UNEXPECTED: The encoding format is not initialized. E_POINTER: pData is NULL pointer/ encoder handle is invalid If querying is successful, *pData contains the current value of the parameter. Caller should guarantee that pData points to enough memory to store the data structure of the parameter NVIDIA CUDA VIDEO ENCODER SP04456-001_v03 | 19
