Revision a0043c6d30 : Enhance the transform skipping decision-making in non-rd mode For large partiti
25 mars 2015, par Yunqing WangChanged Paths :
Modify /vp9/encoder/vp9_pickmode.c
Enhance the transform skipping decision-making in non-rd modeFor large partition blocks(block_size > 32x32), the variance
calculation is modified so that every 8x8 block’s variance
is stored during the calculation, which is used in the
following transform skipping test. Also, the variance for
every tx block is calculated. The skipping test checks all tx
blocks in the partition, and sets the skip flag only if all tx
blocks are skippable. If the skip flag of Y plane is 1, a
quick evaluation is done on UV planes. If the current partition
block is skippable in YUV planes, the mode search checks fewer
inter modes and doesn’t check intra modes.The rtc set borg test(at speed 6) showed that :
Overall psnr : -0.527% ; Avg psnr : -0.510% ; ssim : -0.573%.
Average single-thread speedup on rtc set was 3.5%.
For 720p clips, more speedups were seen.
gipsrecmotion : 13%
gipsrestat : 12%
vidyo : 5 - 9%
dark : 15%
