US 11,082,473 B1 · Method for complexity reduction in video coding by coding parameters reuse

Abstract

A method for video coding with coding parameter reuse is provided as follows. A first video encoding process is executed with respect to a first video source for generating a first video stream by a first video encoder. First coding parameters are exported during the first video encoding process by the first video encoder. The first coding parameters are processed to generate second coding parameters by a parameter processor. A second video encoding process is executed with respect to a second video source for generating a second video stream by a second video encoder. The first and second video sources have different dynamic ranges from each other, and the second coding parameters are introduced into the second video encoding process.
