File Cutter
This tool allows to cut RAW and HDF5 event files.
It shows how to use Metavision SDK Driver API to cut a file between “start” and “end” seconds. The given “start” and “end” times are offsets from the beginning of the file and can be expressed as floating point numbers.
The source code of this tool can be found in <install-prefix>/share/metavision/sdk/driver/cpp_samples/metavision_file_cutter
when installing Metavision SDK from installer or packages. For other deployment methods, check the page
Path of Samples.
Expected Output
The tool cuts the input file and saves the edited outcome to the given path and given filename.
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 on recorded data, provide the full path to an input RAW or HDF5 event file (here, we use a file from our Sample Recordings), the full path to the output file, the “start” and “end” time to cut:
Linux
metavision_file_cutter -i traffic_monitoring.hdf5 -s 2 -e 10 -o output_cut.hdf5
Windows
metavision_file_cutter.exe -i traffic_monitoring.hdf5 -s 2 -e 10 -o output_cut.hdf5
To check for additional options:
Linux
metavision_file_cutter -h
Windows
metavision_file_cutter.exe -h
