2012-09-27Entropy coding for hybrid transformDeb Mukherjee
Separates the entropy coding context models for 4x4, 8x8 and 16x16 ADST variants. There is a small improvement for HD (hd/std-hd) by about 0.1-0.2%. Results on derf/yt are about the same, probably because there is not enough statistics. Results may improve somewhat once the initial probability tables are updated for the hybrid transforms which is coming soon. Change-Id: Ic7c0c62dacc68ef551054fdb575be8b8507d32a8
2012-09-21Separating 8x8DCT use from hybridtransform8x8Deb Mukherjee
With this change, even if hybridtransform8x8 experiment is off, 8x8 dct is used for the I8x8 mode. However note that the gains observed with the hybridtransform8x8 experiment will now be less, since part of the gain is now merged in. Change-Id: I9afb3880906fd0a1368a374041fc08efcf060c54

2012-09-07Partial merge of NEWBESTREFMV and NEW_MVREF.Paul Wilkins
This commit merges those parts of the CONFIG_NEW_MVREF that specifically relate to choosing a better set of candidate MV references into the NEWBESTREFMV experiment. CONFIG_NEW_MVREF will then be used for changes relating to the explicit coding of a cost optimized MV reference in the bitstream as part of MV coding.

2012-09-07MV reference changesPaul Wilkins
Extend experiment to use both vectors from MBs coded using compound prediction as candidates. In final sort only consider best 4 candidates for now but make sure 0,0 is always one of them. Other minor changes to new MV reference code. Pass in Mv list to vp8_find_best_ref_mvs(). Change-Id: Ib96220c33c6b80bd1d5e0fbe8b68121be7997095
2012-09-06New motion vector entropy codingDeb Mukherjee
Adds a new experiment with redesigned/refactored motion vector entropy coding. The patch also takes a first step towards separating the integer and fractional pel components of a MV. However the fractional pel encoding still depends on the integer pel part and so they are not fully independent. Further experiments are in progress to see how much they can be decoupled without affecting performance. All components including entropy coding/decoding, costing for MV search, forward updates and backward updates to probability tables, have been implemented. Results so far: derf: +0.19% std-hd: +0.28% yt: +0.80% hd: +1.15% Patch: Simplifies the fractional pel models: derf: +0.284% std-hd: +0.289% yt: +0.849% hd: +1.254% Patch: Some changes in the models, rebased. derf: +0.330% std-hd: +0.306% yt: +0.816% hd: +1.225% Change-Id: I646b3c48f3587f4cc909639b78c3798da6402678
2012-08-30hybrid transform of 16x16 dimensionJingning Han
Enable ADST/DCT of dimension 16x16 for I16X16 modes. This change provides benefits mostly for hd sequences. Set up the framework for selectable transform dimension. Also allowing quantization parameter threshold to control the use of hybrid transform (This is currently disabled by setting threshold always above the quantization parameter. Adaptive thresholding can be built upon this, which will further improve the coding performance.) The coding performance gains (with respect to the codec that has all other configuration settings turned on) are derf: 0.013 yt: 0.086 hd: 0.198 std-hd: 0.501 Change-Id: Ibb4263a61fc74e0b3c345f54d73e8c73552bf926

2012-08-24New Motion Reference SearchPaul Wilkins
Alternative strategy for finding a list of candidate motion vectors to use as reference values in mv coding and as nearest and near. Sort by sad in vp8_find_best_ref_mvs() rather than just pick the best. Allow 0,0 as a best ref option but not a nearest or near unless there are no alternatives. Encode/Decode verified on at least some clips. Some commented out experimental and stats code still in place. Gain over existing code averages about 1% on derf (alll metrics) with improvement on all clips. Other test results pending. The entropy coding of the mode (nearest/near etc) still depends upon and requires the old "findnear" code so this needs looking at and may provide room for further gains.

2012-08-20Merge "Superblock coding." into experimentalRonald S. Bultje
2012-08-20Superblock coding.Ronald S. Bultje
This commit adds a pick_sb_mode() function which selects the best 32x32 superblock coding mode. Then it selects the best per-MB modes, compares the two and encodes that in the bitstream. The bitstream coding is rather simplistic right now. At the SB level, we code a bit to indicate whether this block uses SB-coding (32x32 prediction) or MB-coding (anything else), and then we follow with the actual modes. This could and should be modified in the future, but is omitted from this commit because it will likely involve reorganizing much more code rather than just adding SB coding, so it's better to let that be judged on its own merits. Gains on derf: about even, YT/HD: +0.75%, STD/HD: +1.5%. Change-Id: Iae313a7cbd8f75b3c66d04a68b991cb096eaaba6

2012-08-14Changed to use reference mv as nearest mvYaowu Xu
The reference motion vector selected by surrounding pixels that has the best matching score is used as nearest motion vector. The change has shown consistent gain on all test sets, compression gains range from .2% to .6%. The variation is largely dependent on various other experiments on or off.
