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.

2014-09-29Fix a bug in calculating delta in VP9 denoiser.JackyChen
When calculating delta in VP8 denoiser, since the block size is fixed to 16x16, the divisor is 256, which is the number of the pixel. But in VP9, the block size varies, the divisor should correspond to the block size. Change-Id: Ibdc1e5d23ba8c788b0d0dc6d406bcdfc34c1b142
2014-09-29Adds two new subpel search methodsDeb Mukherjee
One is a more aggressive version of the pruned subpel tree search where only a single halfpel candidate is searched. The search candidate is based on a surface fit result. The other is a method to obtain the subpel position at one shot based on the same surface fit. The methods have not been deployed in any speed setting yet.

2014-09-26Skip certain ALTREF inter modes in ARF codingJingning Han
This commit enables the encoder to skip checking ALTREF inter modes in ARF coding, if the predicted motion vectors suggest that the GOLDEN_FRAME provides higher prediction accuracy than ALTREF_FRAME. It improves the speed 3 encoding speed by about 5%, at the expense of compression performance loss -0.041% and -0.225% for derf and stdhd, respectively. pedestrian_area 1080p 2000 kbps 66705 b/f, 40.909 dB, 118738 ms -> 66732 b/f, 40.908 dB, 113688 ms old_town_cross 720p 1500 kbps 14427 b/f, 36.256 dB, 62746 ms -> 14412 b/f, 36.252 dB, 60690 ms blue_sky 1080p 1500 kbps 51026 b/f, 35.897 dB, 73310 ms -> 50921 b/f, 35.893 dB, 70406 ms bus CIF 1000 kbps 21301 b/f, 34.841 dB, 7326 ms -> 21248 b/f, 34.837 dB, 7196 ms Change-Id: I76cf88b4d655e1ee3c0cb03c8a5745493040e8d2
2014-09-26Skip the partition search for still framesYunqing Wang
This patch re-enabled the feature in Pengchong's patch (commit 12861260732a4fd5f6b667ce9d5105dc9b606eda). Originally, it was turned on while use_lastframe_partitioning > 0(not used anymore). Now it was added as a feature, and turned on while speed >= 2. As described in the original patch, this feature helps speed up the slideshows in YouTube.
