ENCODER INTERFACES NVGetHWEncodeCaps Description: Syntax: Parameter: Return Value: Remarks: Query if the GPU supports the NVIDIA CUDA Video encoder HRESULT __stdcall NVGetHWEncodeCaps(void) None S_OK: CUDA based encoding is supported E_FAIL: No CUDA capability present None NVCreateEncoder Description: Syntax: Parameter: Return Value: Remarks: Creates the NVIDIA CUDA Video Encoder library object for encoding. HRESULT __stdcall NVCreateEncoder(NVEncoder *pNVEncoder) pNVEncoder [out]This will have a valid encoder object handle on successful creation of encoder library instance S_OK: Success.pNVEncoder parameter will have object handle. E_OUTOFMEMORY : Not enough system memory The object handle is returned though parameter pNVEncoder. Caller should not allocate any memory but just pass reference to NVEncoder type variable. This API does not commit the actual resources required for encoding. NVIsSupportedCodec Description: Syntax: Parameter: Return Value: Remarks: Query if the codec format is supported by the encoder HRESULT __stdcall NVIsSupportedCodec(NVEncoder hNVEncoder, DWORD dwCodecType) hNVEncoder [in] Handle to the encoder instance dwCodecType [in] Codec type support to query S_OK: The format is supported E_NOINTERFACE: The format is not supported E_FAIL: No CUDA capability present E_POINTER: Encoder handle is invalid Only NV_CODEC_TYPE_H264 is are supported NVIDIA CUDA VIDEO ENCODER SP04456-001_v03 | 16
ENCODER INTERFACES NVIsSupportedCodecProfile Description: Syntax: Parameter: Query if the profile for codec format is supported by the encoder HRESULT __stdcall NVIsSupportedCodecProfile(NVEncoder hNVEncoder, DWORD dwCodecType, DWORD dwProfileType) hNVEncoder [in] Handle to the encoder instance dwCodecType [in] Codec type support to query dwProfileType [in] Codec profile support to query. Return Value: S_OK: The profile is supported E_NOINTERFACE: The profile is not supported E_FAIL: No CUDA capability present E_POINTER : Encoder handle is invalid Remarks: For dwCodecType, only NV_CODEC_TYPE_H264 is supported. For dwProfileType, NVVE_H264_PROFILE_BASELINE and NVVE_H264_PROFILE_MAIN are supported. NVVE_H264_PROFILE_HIGH support is limited (only at header bits in bitstream) NVSetCodec Description: Syntax: Parameter: Set encoder codec format HRESULT __stdcall NVSetCodec (NVEncoder hNVEncoder, DWORD dwCodecType) hNVEncoder [in] Handle to the encoder instance dwCodecType [in] Codec format to be set Return Value: S_OK: Successful E_NOINTERFACE: Codec format is not supported E_FAIL: No CUDA capability present E_POINTER : Encoder handle is invalid Remarks: For dwCodecType, only NV_CODEC_TYPE_H264 is supported.
