2014-10-07experimental : partition using 1/8 x 1/8 imageJim Bankoski
The concept: There's too much noise in source pixels for variance and at low bitrate the reconstructed looks nothing like the source so we have problems getting good partitionings with either. This skirts the issue by using a box blur scaled down version for variance calculations. To compare against source_var_ moved keyframe to be rd based like source_var.

2014-10-07Fix skip_txfm issue in rdopt codeYunqing Wang
Fixed an encoder crash. Set skip_txfm to 0 for cases that skip_txfm isn't calculated. Put memcpy of skip_txfm at right place. Change-Id: Ib3b6afc1b251a85b2a853c8138fb3393f48cfef6

2014-10-07Take out repeated block width/height lookup functionsJingning Han
The functions b_width_log2 and b_height_log2 only do direct table fetch. This commit unifies such use cases by using the table directly and removes these functions. Change-Id: I3103fc6ba959c1182886a2799d21b8b77c8a7b6b

2014-10-06Fix eobs buffer pointer mis-useJingning Han
This commit fixes a buffer pointer mis-use in store_coding_context. The compression performance for stdhd set of speed 3 is improved by 0.097%. It fixes issue 869. Change-Id: Idc59e22035eaf39f7133ca04174894374d647ff7
2014-10-06Add SSE2 code and unit test for VP9 denoiser.JackyChen
This SSE2 is based on VP8 denoiser's SSE2 code. In VP8, there are only 16x16 blocks in denoiser, while in VP9, there are 13 different block sizes. By adding this SSE2 code, the improvement of encoder speed is around 20%(using C code vs using SSE2 code), vary for different clips. The unit test for VP9 denoiser is to confirm that the SSE2 code is bit-exact with the C code. The unit test covers all block size. Change-Id: Ic8d8ac26db4ea40a5f146b5678a065af07eaaa3d

2014-10-06Improve two pass VBR accuracy.Paul Wilkins
Adjustments to the GF interval choice and minimum boost. Adjustment to the calculation of 2 pass worst q. Compared to 09/29 head there is metrics hit on derf of (-0.123%,-0.191%) Compared to the September 29 head and a baseline on September 18 baseline the accuracy of the VBR rate control measured on the derf set is as follows:- Mean error % / Mean abs(error %) Sept 18 baseline (-7.0% / 14.76%) Sept 29 head (-15.7%, 19.8%) This check in (-1.5% / 14.4%) The mean undershoot is reduced slightly but the worst case overshoot on e.g. harbour/highway is increased. This will be addressed in a later patch. Change-Id: Iffd9b0ab7432a131c98fbaaa82d1e5b40be72b58
2014-10-05Fix an IOC issue in vp9_rd_pick_inter_mode_sbJingning Han
It is possible that the GOLDEN reference frame is not avaiable, in which setting the predicted mv will be associated with a residual value of INT_MAX. This commit checks this condition before left shift and comparison with that of ALTREF frame, to avoid overflow issue. Change-Id: Ib98c3149dbdd016f2fe5beaafb13f67d469dd07c

2014-10-03Rework partition search skip schemeJingning Han
This commit enables the encoder to skip split partition search if the bigger block size has all non-zero quantized coefficients in low frequency area and the total rate cost is below a certain threshold. It logarithmatically scales the rate threshold according to the current block size. For speed 3, the compression performance loss: derf -0.093% stdhd -0.066% Local experiments show 4% - 20% encoding speed-up for speed 3. blue_sky_1080p, 1500 kbps 51051 b/f, 35.891 dB, 67236 ms -> 50554 b/f, 35.857 dB, 59270 ms (12% speed-up) old_town_cross_720p, 1500 kbps 14431 b/f, 36.249 dB, 57687 ms -> 14108 b/f, 36.172 dB, 46586 ms (19% speed-up) pedestrian_area_1080p, 1500 kbps 50812 b/f, 40.124 dB, 100439 ms -> 50755 b/f, 40.118 dB, 96549 ms (4% speed-up) mobile_calendar_720p, 1000 kbps 10352 b/f, 35.055 dB, 51837 ms -> 10172 b/f, 35.003 dB, 44076 ms (15% speed-up) Change-Id: I412e34db49060775b3b89ba1738522317c3239c8
2014-10-03Incorporate WRAPLOW macro into non-highbitdepth txDeb Mukherjee
Incorporates the WRAPLOW macro into the non-highbitdepth transforms to aid hardware verification between a software C model and an intended hardware implementation though the use of the configure options: --enable-experimental --enable-emulate-hardware. Note that to avoid further discrepancies between the sse/sse2 implementations of the transforms and the C implementation, when the emulate hardware option is invoked, we also disable sse/sse2/etc. Also incudes some minor cleanups/renaming etc. Change-Id: Ib864d8493313927d429cce402982f1c8e45b3287

2014-10-01Modify block transform skipping checkYunqing Wang
Block transform skipping was implemented based on DCT's energy conservation property. Modified the thresholds using zero bin parameters. AC and DC coefficients were checked separately to allow better identifying of skippable blocks. Borg test at speed 3 showed: stdhd set: psnr gain: 0.153%, ssim gain: 0.051%; derf set: psnr gain: 0.023%, ssim gain: 0.036% For most test clips, the encoding speedup is 1% - 2%. parkrun(720p): 7.5% speedup, park_joy(1080p): 3.5% speedup.

2014-10-01Conditionally skip reference frame checkJingning Han
For regular inter frames, if the distance from GOLDEN_FRAME is larger than 2 and if the predicted motion vector of LAST_FRAME gives lower sse than that of GOLDEN_FRAME, skip the GOLDE_FRAME mode checking in the rate-distortion optimization. It provides about 5% speed-up at expense of -0.137% and -0.230% performance down for speed 3.
