Sensor Indexer

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. For more information, see the NVIDIA DriveWorks Release Notes.

./sensor_indexer --sensor=<sensor.virtual> --input=<path/to/sensor/file>

The tool will create a new file next to the input file with same name as input file, however with an attached extension .seek

Command Line Options

The following lists the required and optional command line arguments.

Required Arguments

• --sensor: Name of the virtual sensor to use to parse the file (e.g., --driver=gps.virtual)
• --input: Input file containing recorded data of this sensor (e.g., --input=/home/nvidia/recordings/gps0.bin)

Optional Arguments

• --output: A path where the index file need to be stored (e.g., --output=/home/nvidia/recordings/gps0.bin.seek)

Note

This tool creates output files that, by default, are put into the current working directory. Hence, write permissions to the current working directory are necessary.
