2014-04-08Use source frame difference to make partition decisionYunqing Wang
Calculate the difference variance between last source frame and current source frame. The variance is calculated at 16x16 block level. The variances are compared to several thresholds to decide final partition sizes. An adaptive strategy is implemented to decide using SOURCE_VAR_BASED_PARTITION or FIXED_PARTITION based on motions in the video. The switching test is done once every search_type_check_frequency frames. The selection of source_var_thresh needs to be investigated further later. RTC set Borg test showed 0.424% overall psnr gain, and 0.357% ssim gain. For clips with large enough static area, the encoding speedup is around 2% to 15%.
