group ee_nvinf

Defines common elements used in the API exposed by the Gst-inference plugin.

Defines

NVDSINFER_MAX_DIMS¶

_DS_DEPRECATED_(STR)¶

getDimsCHWFromDims(dimsCHW, dims)¶: Sets values on a NvDsInferDimsCHW structure from a NvDsInferDims structure.

getDimsHWCFromDims(dimsCHW, dims)¶

Typedefs

typedef NvDsInferObjectDetectionInfo NvDsInferParseObjectInfo¶: A typedef defined to maintain backward compatibility.

Enums

enum NvDsInferDataType¶

Specifies the data type of a layer.

Values:

enumerator FLOAT¶: Specifies FP32 format.

enumerator HALF¶: Specifies FP16 format.

enumerator INT8¶: Specifies INT8 format.

enumerator INT32¶: Specifies INT32 format.

enum NvDsInferStatus¶

Enum for the status codes returned by NvDsInferContext.

Values:

enumerator NVDSINFER_SUCCESS¶: NvDsInferContext operation succeeded.

enumerator NVDSINFER_CONFIG_FAILED¶: Failed to configure the NvDsInferContext instance possibly due to an erroneous initialization property.

enumerator NVDSINFER_CUSTOM_LIB_FAILED¶: Custom Library interface implementation failed.

enumerator NVDSINFER_INVALID_PARAMS¶: Invalid parameters were supplied.

enumerator NVDSINFER_OUTPUT_PARSING_FAILED¶: Output parsing failed.

enumerator NVDSINFER_CUDA_ERROR¶: CUDA error was encountered.

enumerator NVDSINFER_TENSORRT_ERROR¶: TensorRT interface failed.

enumerator NVDSINFER_RESOURCE_ERROR¶: Resource error was encountered.

enumerator NVDSINFER_TRTIS_ERROR¶: TRT-IS error was encountered.

enumerator NVDSINFER_UNKNOWN_ERROR¶: Unknown error was encountered.

enum NvDsInferLogLevel¶

Enum for the log levels of NvDsInferContext.

Values:

enumerator NVDSINFER_LOG_ERROR¶

enumerator NVDSINFER_LOG_WARNING¶

enumerator NVDSINFER_LOG_INFO¶

enumerator NVDSINFER_LOG_DEBUG¶

Functions

const char *NvDsInferStatus2Str(NvDsInferStatus status)¶

Get the string name for the status.

Return

String name for the status. Memory is owned by the function. Callers should not free the pointer.
