Sensor Indexer Tool

Description

The NVIDIA® DriveWorks Sensor Indexer Tool creates seeking table files for all supported sensors.
Any virtual sensor that supports index seeks can use those index tables for random access to the data streams.

Prerequisites

This tool is available on the x86 Host System and NVIDIA DRIVE OS Linux.

This tool creates output files that are placed into the current working directory by default. Please ensure the following for your convenience:

  • Write permissions are enabled for the current working directory.
  • Include the tools folder in the binary search path of the system.
  • Execute from your home directory.

Running the Tool

Run this tool by executing:

./sensor_indexer --sensor=[virtual sensor name]
                 --input=[path to sensor file]
                 --timestamp=[path to timestamp file]
                 [--output=[path to output file]]

Parameters

--sensor=[virtual sensor name]
        Description: The name of the virtual sensor used to parse the file.

--input=[path to sensor file]
        Description: The input file containing recorded data for this sensor.

--timestamp=[path to timestamp file]
        Optional: The input file containing timestamp for h264 stream

--output=[path to output file]
        Optional: The path where the index file needs to be stored. If not provided [input].seek will be used.

Output

The Sensor Indexer Tool creates a .seek file with the same name as the input file. It is placed into the current working directory by default.
Ensure write permissions are enabled for the current working directory.
