2014-07-28Move vp9_dec_build_inter_predictors_* to decoder folder.hkuang
Change-Id: Ibe9fa28440cc79ba9f3504d78c7dca7bb01a23e1
2014-07-28Add segmentation map array for current and last frame segmentation.hkuang
The original implementation only allocates one segmentation map and this works fine for serial decode. But for frame parallel decode, each thread need to have its own segmentation map and the last frame segmentation map should be provided from last frame decoding thread. After finishing decoding a frame, thread need to serve the old segmentation map that associate with the previous decoded frame. The thread also need to use another segmentation map for decoding the current frame. Change-Id: I442ddff36b5de9cb8a7eb59e225744c78f4492d8
2014-07-14Merge "Include the right header for VP9 worker thread." into frame_parallelhkuang
2014-07-14Include the right header for VP9 worker thread.hkuang
pthread.h is not supported in windows. vp9_thread.h includes the emulation layer for pthread in windows. Change-Id: I2b1c8ec299928472faca7ebeea998170c9f4d744
2014-07-11Move vp9_thread.* to common.hkuang
Prepare for frame parallel decoding, the reference count buffers need to be protected by mutex. Move vp9_thread.* to common folder so that those buffers could use cross-platform mutex from vp9_thread.*. (cherry picked from commit 337e8015c9deaf8ab7e8d0c3c132160a77dd1590) Change-Id: I0587a08447925f4554d7788686a31483c2ae3f37

2014-07-02Seperate the frame buffers from VP9 encoder/decoder structure.hkuang
Prepare for frame parallel decoding, the frame buffers must be separated from the encoder and decoder structure, while the encoder and decoder will hold the pointer of the BufferPool. Change-Id: I172c78f876e41fb5aea11be5f632adadf2a6f466

2014-07-02Adapt strength of AQ2.Paul Wilkins
Adapt the use of segmentation in AQ mode 2 based on the ambient kf/arf/gf Q. Disable segmentation where the rate per SB is very low and overheads are likely to outweigh the benefits. This patch reduces the -ve average metrics impact of AQ mode 2 while allowing stronger 3 segment AQ in some cases. Average improvement ~0.5-1.0%. Change-Id: I5892dfcc7507c5cc6444531cc7fe17554cf8d0c7
2014-07-02Adds support for reading and writing 10/12-bit y4mDeb Mukherjee
The y4m extension used is the same as the one used in ffmpeg/x264. The patch is adapted from the highbitdepth branch. Also adds unit tests for y4m header parsing and md5 check of the raw frame data, as well as y4m writing. Change-Id: Ie2794daf6dbafd2f128464f9b9da520fc54c0dd6

2014-07-01Re-design quantization processJingning Han
This commit re-designs the quantization process for transform coefficient blocks of size 4x4 to 16x16. It improves compression performance for speed 7 by 3.85%. The SSSE3 version for the new quantization process is included. The average runtime of the 8x8 block quantization is reduced from 285 cycles -> 255 cycles, i.e., over 10% faster.

2014-07-01Elevate NEWMV mode checking threshold in real timeYunqing Wang
The current threshold is knid of low, and in many cases NEWMV mode is checked but not picked as the best mode. This patch added a speed feature to increase NEWMV threshold, so that less partition mode checking goes to check NEWMV. This feature is enabled for speed 6 and 7. Rtc set borg tests showed: 1. Speed 6, overall psnr: -0.088%, ssim: -1.339%; Average speedup on rtc set is 11.1%. 2. Speed 7, overall psnr: -0.505%, ssim: -2.320% Average speedup on rtc set is 12.9%.

2014-06-30Enable encode breakout in real timeYunqing Wang
For real time speed 7, once encode breakout is on(i.e. encoding setting --static-thresh=1), a proper encode breakout threshold is set to speed up the encoder. Set --static-thresh=1, RTC set borg test showed a slight overall psnr loss of 0.162%, but ssim gain of 0.287%. The average speedup on RTC set is 6%, and for some clips, the speedup can be 10+%.

2014-06-30Decide the partitioning threshold from the variance histogramYunqing Wang
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.
