bool	create_encoder (const nvenc_config &config, const video::config_t &client_config, const nvenc_colorspace_t &colorspace, NV_ENC_BUFFER_FORMAT buffer_format)
	Create the encoder.

	Destroy the encoder. Derived classes classes call it in the destructor.

nvenc_encoded_frame	encode_frame (uint64_t frame_index, bool force_idr)
	Encode the next frame using platform-specific input surface.

Additional Inherited Members
Protected Member Functions inherited from nvenc::nvenc_d3d11
bool	init_library () override
	Required. Used for loading NvEnc library and setting `nvenc` variable with `NvEncodeAPICreateInstance()`. Called during `create_encoder()` if `nvenc` variable is not initialized.

Protected Member Functions inherited from nvenc::nvenc_base
uint32_t	min_struct_version (uint32_t version, uint32_t v11_struct_version=0, uint32_t v12_struct_version=0)
	This function returns the corresponding struct version for the minimum API required by the codec.

bool	nvenc_failed (NVENCSTATUS status)

virtual bool	synchronize_input_buffer ()
	Optional. Override if you must perform additional operations on the registered input surface in the beginning of `encode_frame()`. Typically used for interop copy.

virtual bool	wait_for_async_event (uint32_t timeout_ms)
	Optional. Override if you want to create encoder in async mode. In this case must also set `async_event_handle` variable.
