2012-08-14Merge "Changed to use reference mv as nearest mv" into experimentalYaowu Xu
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.

2012-08-10Code cleanup.Paul Wilkins
Add local variable in several places to reference the MB mode info structure. Currently this is usually accessed in the code as x->e_mbd.mode_info_context->mbmi.* or in some places xd->mode_info_context->mbmi.* Resolved some uses of x-> for the MACROBLOCKD structure. Rebased without dependency on motion reference experiment. Change-Id: If6718276ee4f2ef131825d1524dfdb02a3793aed

2012-08-07A bit of temporary relief on encoder slownessYaowu Xu
The commit replaces run-time initialization of cosine constants with static constant values, which provides ~30% relief on slow speed. The real solution, however will be to implement integer versions of those functions that current use float/double. Change-Id: Ie3ff1793509653d78dd1aeaf88cc6737da1bc55f
2012-08-07a new way of determining reference motion vectorYaowu Xu
Using surrounding reconstructed pixels from left and above to select best matching mv to use as reference motion vector for mv encoding. Test results: AVGPSNR GLBPSNR VPXSSIM Derf: 1.107% 1.062% 0.992% Std-hd:1.209% 1.176% 1.029% Change-Id: I8f10e09ee6538c05df2fb9f069abcaf1edb3fca6
2012-08-06Refactoring hybrid transform codingJingning Han
The forward and inverse hybrid transforms are now performed using single function modules, where the dimension is sent as argument. Added an inline function clip8b to clip the reconstruction pixels into range of 0-255. Change-Id: Id7d870b3e1aefc092721c80c0af6f641eb5f3747

This allows building on MountainLion as the 10.6 SDK has been removed from the latest Xcode version (4.4 4F250). Also fix all warnings for that build. Change-Id: Ib70bca4a25295f13595f0d10ea9f0229631de5a4

Merged in the high_precision_mv experiment to make it easier to work on new mv encoding strategies. Also removed coef_update_probs3(). Change-Id: I82d3b0bb642419fe05dba82528bc9ba010e90924
2012-08-03Replacing the 8x8 DCT with 8x8 ADST/DCT for I8x8Jingning Han
Fixed the code review comments. Under the htrans8x8 experiment the 8X8 DCT in the I8X8 mode is replaced with a combination of 8X8 ADST and DCT. Overall coding gains with the htrans8x8 experiment are: derf: 0.486 std-hd: 1.040 hd: 1.063 yt: 0.506 Note that part of the gain comes from bigger transforms (8x8 instead of 4x4) and part comes from replacing the DCT wth the ADST.

2012-08-02Use 8x8 DCT transform for I8X8 prediction modeJingning Han
Apply 2D-DCT transform of dimension 8x8 to encode prediction residuals of I8X8 mode. Brought back block type 3 probability context model for 8x8 tokens, which is used for the coefficients of Y blocks in I8x8 modes. The coefficient costs estimate of I8X8 mode in rate-distortion is also changed appropriately. Performance results: derf: 0.246 yt: 0.114 std-hd: 0.730 hd: 0.670 Change-Id: If1d970eeb4e1827c9f0d2c5b27d33089b347ea27
2012-07-31Merging and bug-fix in enhanced_interp experimentDeb Mukherjee
Merged the enhanced_interp experiment. Found and fixed a bug in the include files framework, whereby certain encoder files were still using the old INTERP_EXTEND value of 3 instead of 4. The thresholds for mv range mcomp.c need a small adjustment to prevent crashes. The results are more or less unchanged. Change-Id: Iac5008390f1efc97ce1102fbb5f8989c847fb579
2012-07-30Adds support for switchable interpolation filters.Deb Mukherjee
Allows for swtiching/setting interpolation filters at the MB level. A frame level flag indicates whether to use a specifc filter for the entire frame or to signal the interpolation filter for each MB. When switchable filters are used, the encoder chooses between 8-tap and 8-tap sharp filters. The code currently has options to explore other variations as well, which will be cleaned up subsequently. One issue with the framework is that encoding is slow. I tried to do some tricks to speed things up but it is still slow. Decoding speed should not be affected since the number of filter taps remain unchanged. With the current version, we are up 0.5% on derf on average but some videos city/mobile improve by close to 4 and 2% respectively. If we did a full-search by turning the SEARCH_BEST_FILTER flag on, the results are somewhat better. The framework can be combined with filtered prediction, and I seek feedback regarding that. Rebased. Change-Id: I8f632cb2c111e76284140a2bd480945d6d42b77a
