This work is inspired by Jim Lindner’ Filmic project and by in-depth discussions with Claudio Weidmann. The MSMI video codec is developed since early 2017 by Reto Kromer, who first presented it publicly in 2018.

The openMSMI package contains the libmsmi C library, implementing the MSMI video codec, and the openmsmi Bash command−line interface to libmsmi, allowing to encode, decode, play and analyse multispectral moving images. The package is released under a Creative Commons Attribution 4.0 International License and is provided «as is» without warranty or support of any kind.

A PDF of the current man page is available.

The source code will become freely available, as soon as a public beta not requiring special user’s skills will be released. Our inner circle can already install and test an alpha, which comes with a short test file, by running the following command:

brew install avpres/formulae/openmsmi

The Homebrew/Linuxbrew formula has been successfully tested on x86_64 architectures running on the following operating systems:

  • Linux: Ubuntu 18.04.1 LTS, 16.04.5 LTS and 14.04.5 LTS, and Slackware 14.2
  • Macintosh: macOS 10.13.6 and 10.12.6, and OS X 10.11.6
  • Windows 10 Pro and Home running the Debian 9.5 or Ubuntu 18.04.1 LTS app
