ABSTRACT:
First-pass processing is applied to a video sequence comprising a plurality of video frames to generate first-pass processing results for the video sequence. After completing the first-pass processing, subsequent-pass processing is applied to the video sequence using the first-pass processing results to generate subsequent-pass processing results. An encoded bitstream is generated for the video sequence based on the subsequent-pass processing results.
