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:

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):
Linux
metavision_raw_info -i 80_balls.raw
Windows
metavision_raw_info.exe -i 80_balls.raw
To check for additional options:
Linux
metavision_raw_info -h
Windows
metavision_raw_info.exe -h
