2013-01-14Remove compound intra-intra experiment.Ronald S. Bultje
This experiment gives little gains and adds relatively much code complexity (and it hinders other experiments), so let's get rid of it. Change-Id: Id25e79a137a1b8a01138aa27a1fa0ba4a2df274a

2013-01-14changed UV plane loop filtering for TX_8X8Yaowu Xu
In commit 9a1d73d, loop filtering was added for UV 4x4 boundaries when TX_8X8 is used by a MB. This commit further refined the decision to be based on the actual transform used for the UV planes. When UV planes use 4x4 transform, i.e. when prediction mode used is either I8X8_PRED or SPLITMV, UV planes are filtered on 4x4 boundaries, and no filtering is applied on 4x4 block boundaries when UV planes use 8X8 transform.

2013-01-14Reset x->skip for each iteration in the RD loop.Ronald S. Bultje
This prevents ill-defined behaviour, such as setting x->skip for a mode that is excluded because of frame-level flags (e.g. filter selection, compound prediction selection), then not breaking out of the RD loop because the mode is not allowed, but keeping the flag on. Whatever mode is iterated through next in the RD loop will then carry this flag, and all sort of bad stuff happens, such as x->skip being set on intra pred modes.

Previous commit does not build cleanly on Jenkins with the DWT/DCT hybrid experiment enabled (--enable-dwtdcthybrid). Change-Id: Ia67e8f59d17ef2d5200ec6b90dfe6711ed6835a5
2013-01-12Further enhancements/fixes on dct/dwt hybrid txfmDeb Mukherjee
Fixes some scaling issues. Adds an option to only compute the dct on the low-low subband for 32x32 and 64x64 blocks using only a single 16x16 dct after 1 and 2 wavelet decomposition levels respectively. Also adds an option to use a 8x8 dct as building block. Currenlty with the 2/6 filter and with a single 16x16 dct on the low low band, the reuslts compared to full 32x32 dct is as follows: derf: -0.15% yt: -0.29% std-hd: -0.18% hd: -0.6% These are my current recommended settings, since the 2/6 filter is very simple. Results with 8x8 dct are about 0.3% worse. Change-Id: I00100cdc96e32deced591985785ef0d06f325e44

2013-01-11WIP: Added sse2 version of vp9_mb_lpf_horizontal_edge_wScott LaVarnway
and vp9_mb_lpf_vertical_edge_w_sse2. This was quickly done so we can run some tests over the weekend. Future commits will optimize/refactor these functions further. The decoder performance improved by ~17% for the clip used. Change-Id: I612687cd5a7670ee840a0cbc3c68dc2b84d4af76

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

2013-01-04Further 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.
