RAW Info Application

This application allows you to get information about a RAW file including

  • Duration

  • Event encoding type

  • Camera info: sensor generation, ID, serial number

  • Number of events, first and last timestamps, average event rate

The source code is installed in <install-prefix>/share/metavision/sdk/driver/apps/metavision_raw_info/metavision_raw_info.cpp.

Expected Output

The application reads a RAW file and prints information about the file and its data to the console.

Here is an example of the outcome:


Name                80_balls.raw
Path                80_balls.raw
Duration            6s 284ms 62us
Event encoding      EVT2
Camera generation   3.0
Camera systemID     21
Camera subsystemID  2415920130
Camera serial       0000ffff


Type of event       Number of events    First timestamp     Last timestamp      Average event rate
CD                  4588809             54                  6284062             730.2 Kev/s

How to start

You can directly execute pre-compiled binary installed with Metavision software or compile the source code as described in this tutorial.

To start the pre-compiled executable based on recorded data, provide the full path to a RAW file (here, we use the file from Metavision Dataset):


metavision_raw_info -i 80_balls.raw


metavision_raw_info.exe -i 80_balls.raw

To check for additional options:


metavision_raw_info -h


metavision_raw_info.exe -h
