摘要： A multi-pass video encoder includes a video encoding module that encodes a video signal based on an initial configuration data set to generate an initial processed video signal and an initial output data set. An application coding control module generates the initial configuration data set and generates a first updated configuration data set based on both the initial processed video signal and the initial output data set. The video encoding module further encodes the video signal based on the first updated configuration data set to generate a first updated processed video signal and a first updated output data set.
