2013-01-09New prediction filterAdrian Grange
This patch removes the old pred-filter experiment and replaces it with one that is implemented using the switchable filter framework. If the pred-filter experiment is enabled, three interopolation filters are tested during mode selection; the standard 8-tap interpolation filter, a sharp 8-tap filter and a (new) 8-tap smoothing filter. The 6-tap filter code has been preserved for now and if the enable-6tap experiment is enabled (in addition to the pred-filter experiment) the original 6-tap filter replaces the new 8-tap smooth filter in the switchable mode. The new experiment applies the prediction filter in cases of a fractional-pel motion vector. Future patches will apply the filter where the mv is pel-aligned and also to intra predicted blocks.

2013-01-08Adds 64x64 hybrid dct/dwt transformDeb Mukherjee
This is to add to the 64x64 transform experiment as an alternative to a 64x64 DCT. Two levels of wavelet decomposition is used on a 64x64 block, followed by 16x16 DCT on the four lowest subbands. The highest three subbands are left untransformed after the first level DWT. Change-Id: I3d48d5800468d655191933894df6b46e15adca56

2013-01-07minor loop filter refactoring and cleanupYaowu Xu
This commit did a couple of minor cleanup/refactoring to prepare for futher loop filter experiments. It merged y_only version of loop filter function into the regular one, which makes sure that same logic is used for functions for picking level and for actual loop filtering.

2013-01-04Fix mode selection infinite loop bugAdrian Grange
Mode selection for SBs could enter an infinite loop because the interpolation filter mode index was not being reset correctly. Change-Id: I4bbe726f29ef5b6836e94884067c46084713cc11
2013-01-04Further change to mv reference search.Paul Wilkins
This experimental change reorders the search so that all possible references that match the target reference frame are tested first and these in order of distance from the current block. These will usually be the highest scoring candidates. If we do not find enough good candidates this way we try non matching cases. These will usually be lower scoring candidates. The change in order together with breakouts when we have found enough candidates should reduce the computational cost and especially reduce the number of sort operations. Quality Results: Std Hd +0.228%, Hd +0.074%, YT +0.046%, derf +0.137% This effect is probably due to the fact that more distant weak candidates are now less likely to get "promoted" over near candidates even if they are repeated.

2013-01-03New interpolation filter selection algorithmAdrian Grange
Old Scheme: When SWITCHABLE filter selection is enabled the encoder evaluates the use of each interpolation filter type and selects the best one to use at the MB level. A frame- level flag can be set to force the use of a particular filter type for all MBs in a frame if it is more efficient to encode that way. The logic here involved a Q dependent threshold that assumed that the second 8-tap filter was a high-pass filter. However, this requires a trip around the recode loop. If the frame-level flag indicates use of a particular filter, the other filters are not evaluated in the pick_mode loop. New Scheme: Each filter type is evaluated at the MB level and a record of the best filter is kept, irrespective of what filter is signaled at the frame-level. Once all MBs have been encoded, a decision is made as to what frame-level mode to set for the *next* frame. If one filter is used by 80% or more of the MBs, then this filter is forced since it is assumed that this will be more efficient if the next frame has similar characteristics. i.e. there is a one-frame lag between measuring the filter selection and setting the frame-level mode to use.

2012-12-27Skip finding best ref_mvs when the mode is ZEROMVYunqing Wang
Read mode before calling vp9_find_best_ref_mvs(). If the mode is ZEROMV, the best ref_mvs are not needed. Then, we can skip calling vp9_find_best_ref_mvs(). Change-Id: I5baa3658dd3f1c7107211cbbbcf919b4584be2e2
2012-12-27Switch the order of calculating 2-D inverse transformYunqing Wang
The 2-D inverse transform X = M1*Z*Transposed_M2 was calculated in 2 steps from left to right: 1. Vertical transform: Y = M1*Z 2. Horizontal transform: X= Y*Transposed_M2 In SIMD, a transpose is needed in vertical transform. Here, switched the calculation order to do it from right to left. In this way, we could eliminate that transpose by writing the intermediate results out to their transposed positions. Change-Id: I34dfe5eb01292f6e363712420d99475e2e81e12c

2012-12-19New previous coef context experimentDeb Mukherjee
Adds an experiment to derive the previous context of a coefficient not just from the previous coefficient in the scan order but from a combination of several neighboring coefficients previously encountered in scan order. A precomputed table of neighbors for each location for each scan type and block size is used. Currently 5 neighbors are used. Results are about 0.2% positive using a strategy where the max coef magnitude from the 5 neigbors is used to derive the context. Change-Id: Ie708b54d8e1898af742846ce2d1e2b0d89fd4ad5

2012-12-19make: fix dependency generationJohn Koleszar
Remove an extra level of escaping around the $@ variable to get valid output. Prior to this change, modifying header files did not trigger a rebuild of sources dependent on them. Change-Id: I93ecc60371b705b64dc8a2583a5d31126fe3f851
2012-12-19Use boolcoder API instead of inliningJohn Koleszar
This patch changes the token packing to call the bool encoder API rather than inlining it into the token packing function, and similarly removes a special get_signed case from the detokenizer. This allows easier experimentation with changing the bool coder as a whole. Change-Id: I52c3625bbe4960b68cfb873b0e39ade0c82f9e91

2012-12-18Changed MAX_PSNR to 100Yaowu Xu
The MAX_PSNR was used to assign a "psnr" number when the mse is close to zero. The direct assignment is used to prevent divide by zero in computation. Changing it from 60 to 100 to be consistent against what is being done in VP9 Change-Id: I4854ffc4961e59d372ec8005a0d52ca46e3c4c1a
