Cisco Thor Video Codec

Thor was an experimental video codec developed by Cisco as a candidate for the NETVC (Next-Gen Video) initiative. While Thor itself is not used as-is, some of its technology contributed to the development of AV1. It's a piece of codec research history with source available for st
