experimental
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.

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
