On July 22, 2015, Thor was presented to the IETF as a candidate for their NETVC video standard.[2] Thor uses some Cisco elements that are also used by HEVC.[3] 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.[4]
According to Steinar Midtskogen, a principal Thor developer and AV1 contributor, Thor is in good shape for real-time CPU encoding (as of NETVC meeting 101, March 19, 2018), in strong contrast to AV1 at the same time.[8] Thor development had stalled for the finalization of AV1, but Midtskogen envisaged further Thor development by merging the Daala entropy coder and adding more tools for screen content.[9]
