Batch metadata structure for preprocessing operations.

Variables:

• target_unique_ids – list of int, target unique ids for which meta is prepared.

• tensor_meta – NvDsPreProcessTensorMeta, size of raw tensor buffer.

• roi_vector – list of :class:`NvDsRoiMeta`, list of roi vectors per batch.

• private_data – capsule, pointer to buffer from scaling pool.

cast(self: capsule) → pyds.GstNvDsPreProcessBatchMeta

Cast given object/data to GstNvDsPreProcessBatchMeta, call pyds.GstNvDsPreProcessBatchMeta.cast(data)
