2013-05-31vp9_find_mv_refs_idx change for last frame.Paul Wilkins
Restrict get_matching_candidate() to considering mvs at 8x8 and larger sizes for last frame case. This is to reduce the HW load of using vectors down to the 4x4 level from the previous frame. Change-Id: I6505e610fd63a4e22d67f136aec7905a01b893ba

2013-05-30Creates a new speed 1:Jim Bankoski
This speed 1 - uses variance threshold stolen from static-thresh to determine split. Any superblock with greater than the variance set by static thresh * quantizer index squared is split. In addition transform size is set to largest size less than or equal to partition size, sub pixel filter is set to normal, and only 12 modes are used at all.

Change-Id: Ieb4669ae564bec9f3051485ecdf186cb4e00decb
2013-05-30Remove splitmv.Ronald S. Bultje
We leave it in rdopt.c as a local define for now - this can be removed later. In all other places, we remove it, thereby slightly decreasing the size of some arrays in the bitstream. Change-Id: Ic2a9beb97a4eda0b086f62c039d994b192f99ca5
2013-05-30Remove i4x4_pred.Ronald S. Bultje
It remains as a local define in rdopt.c so we can distinguish between split and non-split modes in the RD loop, but disappears outside that scope in the codec. Change-Id: I98c18fe5ab7e4fbd1d6620ec5695e2ea20513ce9

The commit changed to use a new variant of Walsh-Hadamard Transform by Tim Terriberry. This new variant has the best compression among a number of variants that developed by Tim. Change-Id: Icb3a88515463cfc644b17ca046fcd139db2557e9

2013-05-29Add intra_only and reset_frame_context flagsAdrian Grange
Added two flags to the frame header: intra_only: Signals that the frame is encoded using only INTRA coding modes. reset_frame_context: Indicates that the coding context specified in the frame header should be reset to default values before the frame is encoded/decoded. Change-Id: I182d46f1f84fb67a13c46ad767f246a38d7861a2
2013-05-29Balancing coef-tree to reduce bool decodesDeb Mukherjee
This patch changes the coefficient tree to move the EOB to below the ZERO node in order to save number of bool decodes. The advantages of moving EOB one step down as opposed to two steps down in the other parallel patch are: 1. The coef modeling based on the One-node becomes independent of the tree structure above it, and 2. Fewer conext/counter increases are needed. The drawback is that the potential savings in bool decodes will be less, but assuming that 0s are much more predominant than 1's the potential savings is still likely to be substantial. Results on derf300: -0.237% Change-Id: Ie784be13dc98291306b338e8228703a4c2ea2242

2013-05-29Residual coding to cache energy class of tokens.Sami Pietila
Proposal for tuning the residual coding by changing how the context from previous tokens is calculated. Storing the energy class of previous tokens instead of the token itself eases the critical path of HW implementations. Change-Id: I6d71d856b84518f6c88de771ddd818436f794bab

Moving clr_type, error_resilient_mode, refresh_frame_context, frame_parallel_decoding_mode, frame_context_idx from compressed partition to uncompressed frame header.

2013-05-27Reduce bmi buffer length from 16 to 4Jingning Han
This commit removes the use of bmi_ in the first-pass encoding by forcing encode_intra4x4block_ to use DC_PRED, followed by DCT_DCT only, as John suggested. This makes the need for bmi buffer only up to 4 entries, instead of 16. Change-Id: I3410007dfae789ee46a09ae20c39d3ce3c7954aa

2013-05-23Change txfm_type decisionYaowu Xu
The changing in intra coding to base on transform block, i.e. pred-> txfm->quant->dequant-itxfm->recon, made all blocks within a prediction unit behave consistently, there is no longer a need to handle blocks differently based on the position within a predicitn block. So this commit simplifies the decision of transform type to be based on prediction mode only. Change-Id: If96cb72386f2e9186126ace88afa35ef085b6c96
