inlineoverridevirtualinherited

Perform the transformation on the input buffer from the buffer array, indexed using m_TransformIdx.

Parameters

[in]	src	The input batch buffer array.
[in]	mainStream	The main processing CUDA stream.
[in]	done	The call function to be called after transformation.

Returns

NVDSINFER_SUCCESS or NVDSINFER_RESOURCE_ERROR.

Implements nvdsinferserver::IPreprocessor.
