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 pre-compiled executable, provide the full path to a file (here, we use a file from Metavision Datasets):
Linux
metavision_file_info -i 80_balls.hdf5
Windows
metavision_file_info.exe -i 80_balls.hdf5
