2012-09-10Hybrid transform cleanupsDeb Mukherjee
Some cleanups that will make it easier to maintain the code and incorporate upcoming changes on entropy coding for the hybrid transforms. Change-Id: I44bdba368f7b8bf203161d7a6d3b1fc2c9e21a8f
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

2012-08-24change to properly account for coef scaling in unit testsYaowu Xu
The transform functions in experimental branch absorbed a scaling factor of 4 to allow quantization steps closer to unit quantizer. This commit added scaling code in between forward and inverse transform to properly account for the scaling factor. Change-Id: I9a573ddc1ffa74973b34800a5da1a56dbabe0949
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.

2012-08-20Superblock 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

2012-08-16Fixed decoder mismatch issueJingning Han
Resolved the decoder mismatch issue due to quantization parameter threshold for hybrid transform coding. The macroblock dequantizer initialization is moved to be performed before coefficient detokenization, since the (de)tokenization is now dependent on the macroblock level quantization parameter.
