Data encoding type
Camera info: sensor generation, ID, serial number
Number of events, first and last timestamps, average event rate
The source code of this tool can be found in <install-prefix>/share/metavision/sdk/stream/cpp_samples/metavision_file_info
when installing Metavision SDK from installer or packages. For other deployment methods, check the page

How to start
You can directly execute pre-compiled binary installed with Metavision SDK or compile the source code as described in this tutorial.
To start the tool, provide the full path to an event file (here, we use an HDF5 file from Metavision Datasets):
Linux
metavision_file_info -i 80_balls.hdf5
Windows
metavision_file_info.exe -i 80_balls.hdf5
