VMF Tool is a command-line utility to write and read metadata information from a video file. It is based on the Intel Video Metadata Framework SDK, available at https://software.intel.com/en-us/vmf-sdk/download.
vmftool was written for Linux, but support was later hacked together for Mac OS X and Windows.
Operation is:
#!bash
./vmtool.linux --write <video_path> <data_path>
./vmtool.linux --read <video_path>
