Abstract

A video on demand (VOD) server generates multiple video output qualities (bit rates), resolutions and codecs to best video quality for all viewers’ internet connection. While each codec optimizes tools and does computation-quality tradeoff there isn't much work to exploit computation reduction across codecs. In this work, we propose some methods to achieve this. Specifically, we use VP9 mode decision to reduce the computational requirements of AV1 encoding.
