2014-11-24vp9_ethread: modify VP9_COMP structureYunqing Wang
This patch modified struct VP9_COMP. Created a struct ThreadData to include data that need to be copied for each thread. In multiple thread case, one thread processes one tile. all threads share one copy of VP9_COMP, (refer to VP9_COMP *cpi in the code) but each thread has its own copy of ThreadData, (refer to ThreadData *td in the code). Therefore, within the scope of encode_tiles(), both cpi and td need to be passed as function parameters. In single thread case, the FRAME_COUNTS pointer in ThreadData points to "counts" in VP9_COMMON. Change-Id: Ib37908b2d8e2c0f4f9c18f38017df5ce60e8b13e
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

2013-05-20Updating the model coef experimentDeb Mukherjee
Cleans up the experiment. Actually uses reduced counts for backward updates, and reduced number of probabilities in the context. No change in bitstream when the experiment is on. Between expt on and off: derfraw300 is down only -0.062% (which is better than when expts were run previously). Change-Id: I55285a049a0c22810bdb42914212ab5a4f8521b5
2013-04-29Immigrate tokenize_mb into tokenize_sbJingning Han

We are immigrating the functionalities of macroblock handles into superblock ones, and eventually will remove encode_mb and decode_mb. To be continued on detokenize_ module.

Adds an experiment that codes an end-of-orientation symbol for every eligible zero encountered in scan order. This cleans out various other sub-experiments that were part of the origiinal patch, which will be later included if found useful. Results are slightly positive on all sets (0.1 - 0.2% range).

2013-04-09Make SB coding size-independent.Ronald S. Bultje
Merge sb32x32 and sb64x64 functions; allow for rectangular sizes. Code gives identical encoder results before and after. There are a few macros for rectangular block sizes under the sbsegment experiment; this experiment is not yet functional and should not yet be used.

2013-03-26Use above/left (instead of previous in scan-order) as token context.Ronald S. Bultje
Pearson correlation for above or left is significantly higher than for previous-in-scan-order (absolute values depend on position in scan, but in general, we gain about 0.1-0.2 by using either above or left; using both basically just makes this even better). For eob branch skipping, we continue to use the previous token in scan order. This helps about 0.9% on derf after re-training on a limited data set. Full re-training and results on larger-resolution clips are pending. Note that this commit breaks trellis, so we can probably get further gains out of it by fixing trellis at some later point.

2013-03-07Re-add support for ADST in superblocks.Ronald S. Bultje
This also changes the RD search to take account of the correct block index when searching (this is required for ADST positioning to work correctly in combination with tx_select). Change-Id: Ie50d05b3a024a64ecd0b376887aa38ac5f7b6af6
2013-03-04Make superblocks independent of macroblock code and data.Ronald S. Bultje
Split macroblock and superblock tokenization and detokenization functions and coefficient-related data structs so that the bitstream layout and related code of superblock coefficients looks less like it's a hack to fit macroblocks in superblocks. In addition, unify chroma transform size selection from luma transform size (i.e. always use the same size, as long as it fits the predictor); in practice, this means 32x32 and 64x64 superblocks using the 16x16 luma transform will now use the 16x16 (instead of the 8x8) chroma transform, and 64x64 superblocks using the 32x32 luma transform will now use the 32x32 (instead of the 16x16) chroma transform. Lastly, add a trellis optimize function for 32x32 transform blocks. HD gains about 0.3%, STDHD about 0.15% and derf about 0.1%. There's a few negative points here and there that I might want to analyze a little closer. Change-Id: Ibad7c3ddfe1acfc52771dfc27c03e9783e054430
