This commit enables a chessboard pattern constrained partition search for 720p and above resolutions. The scheme applies stricter partition search to alternative blocks based on its above/left neighboring blocks' partition range, as well as that of the collocated blocks in the previous frame. It is currently turned on at 16x16 block size level. The chessboard pattern is flipped per coding frame. The speed 3 runtime is reduced: park_joy_1080p, 652832 ms -> 607738 ms (7% speed-up) pedestrian_area_1080p, 215998 ms -> 200589 ms (8% speed-up) The compression performance is changed: hd -0.223% stdhd -0.295% Change-Id: I2d4d123ae89f7171562f618febb4d81789575b19
