Abstract:
A system and method provide a video description length (VDL) guided constant quality video encoding strategy with bitrate constraint and a video coding system for optimizing encoding bitrate, distortion and complexity of an input video. The method obtains an overall VDL, temporal VDL and spatial VDL of the input video and compares the overall VDL, temporal VDL and spatial VDL of the input video with a reference VDL, temporal VDL and spatial VDL. Based on the comparison, the method adjusts the encoding bitrate, the overall encoding complexity, temporal encoding complexity and spatial encoding complexity of the input video and encodes the input video with the adjusted encoding bitrate, overall encoding complexity, temporal encoding complexity and spatial encoding complexity of the input video.
