Please note that the YCoCg video codec has been superseded on the 12th of January 2019 by its generalisation MovIm. openYCoCgIt’s the story of a video codec, built on the Y′COCG colour space and specifically designed for restoration purposes. This video codec is developed since early 2014 by Reto Kromer, who first presented it publicly in 2015, but it was called YCoCg only two years later.1 We use the unofficial FourCC “YCOG” for this video codec. The openYCoCg package contains the libycocg C library, implementing the YCoCg video codec, and the openycocg Bash command−line interface to libycocg, allowing to encode, decode, play and analyse Y′COCG video files. The package is released under a 3-Clause BSD 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. A Little Context
