|Covid-19|Thor (video codec) Wikipedia
Thor is a royalty free video codec under development by Cisco Systems. The specifications of Thor were available in various Internet-Drafts.
On July 22, 2015, Thor was presented to the IETF as a candidate for their NETVC video standard. Thor uses some Cisco elements that are also used by HEVC. As part of the NETVC work, the Constrained Low-Pass Filter (CLPF) and motion compensation techniques used in Thor were tested in conjunction with the lapped transform coding techniques from the Daala codec.
