ENCODER INTERFACES IsSupportedCodecProfile Description: Syntax: Parameter: Return Value: Remarks: Query if the profile for codec format is supported by the encoder HRESULT IsSupportedCodecProfile (DWORD dwCodecType, DWORD dwProfileType) dwCodecType [in] Codec type support to query dwProfileType [in] Codec profile support to query. S_OK: The profile is supported E_NOINTERFACE: The profile is not supported E_FAIL: No CUDA capability present For dwCodecType, only NV_CODEC_TYPE_H264 is supported. For dwProfileType, NVVE_H264_PROFILE_BASELINE and NVVE_H264_PROFILE_MAIN are supported for the H.264 codec. NVVE_H264_PROFILE_HIGH support is limited (only at header bits in bitstream) SetCodecType Description: Syntax: Parameter: Return Value: Remarks: Set encoder codec format HRESULT SetCodecType(DWORD dwCodecType) dwCodecType [in] Codec format to be set S_OK: Sucessful E_FAIL: Fail For dwCodecType, only NV_CODEC_TYPE_H264 is supported. This API must be called before the filter goes to run state, otherwise the graph will not play. NVIDIA CUDA VIDEO ENCODER SP04456-001_v03 | 12
ENCODER INTERFACES GetCodecType Description: Syntax: Parameter: Return Value: Remarks: Get the current encoding format HRESULT GetCodecType(DWORD *pdwCodecType) pwdCodecType [out] Pointer to store the current encoding format S_OK: Successful E_FAIL: The encoding format is not initialized E_POINTER: pwdCodecType is NULL pointer If successful, *pdwCodecType stores the current encoding format IsSupportedParam Description: Syntax: Parameter: Return Value: Remarks: Query if the parameter type is supported HRESULT IsSupportedParam(DWORD dwParamType) dwParamType [in] Parameter support to query S_OK: The parameter is supported E_FAIL: The parameter is not supported Parameter types are listed in Encoder Parameters SetParamValue Description: Syntax: Parameter: Return Value: Remarks: 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 SetParamValue(DWORD dwParamType, LPVOID pData) 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 Parameter types are listed in Encoder Parameters NVIDIA CUDA VIDEO ENCODER SP04456-001_v03 | 13
