The vbp thresholds are set seperately for boosted/non-boosted superblocks according to their segment_id. This way we don't have to force the boosted blocks to split to 32x32. Speed 6 RTC set borg test result showed some quality gains. Overall PSNR: +0.199%; Avg PSNR: +0.245%; SSIM: +0.802%. No speed change was observed. Change-Id: I37c6643a3e2da59c4b7dc10ebe05abc8abf4026a

Currently, VP9 supports column-tile encoding, which allows a frame to be encoded in multiple column tiles independently. The number of column tiles are set by encoder option "--tile-columns". This provides a way to encode a frame in parallel. Based on previous set of patches, this patch implemented the tile- based multi-threaded encoder. Each thread processes one or more tiles. Usage: For HD clips: --tile-columns=2 --threads=1/2/3/4 While using 4 threads, tests showed that the encoder achieved 2.3X - 2.5X speedup at good-quality speed 3, and 2X speedup at realtime speed 5.

Before encoding a frame, calculate and store each 16x16 block's variance of source difference between last and current frame. Find partitioning threshold T for the frame from its variance histogram, and then use T to make partition decisions. Comparing with fixed 16x16 partitioning, rtc set test showed an overall psnr gain of 3.242%, and ssim gain of 3.751%. The best psnr gain is 8.653%. The overall encoding speed didn't change much. It got faster for some clips(for example, 12% speedup for vidyo1), and a little slower for others. Also, a minor modification was made in datarate unit test.

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%.
