Abstract
In this paper, we propose a new video encoding strategy - Video description length
guided Constant Quality video coding with Bitrate Constraint (V-CQBC), for large
scale video transcoding systems of video charing websites with varying unknown
video contents. It provides smooth quality and saves bitrate and computation for
transcoding millions of videos in both real time and batch mode. The new encoding
strategy is based on the average bitrate-quality regression model and adapt to the
encoded videos. Furthermore, three types of video description length (VDL),
describing the video overall, spatial and temporal content complexity, are proposed
to guide video coding. Experimental results show that the proposed coding strategy
with saved computation could achieve better or similar RD performance than other
coding strategies.
