2013-06-26Merge "Make intra predictor reference buffer configurable"Jingning Han
2013-06-26Make intra predictor reference buffer configurableJingning Han
This commit enables configurable reference buffer pointer for intra predictor. This allows later removal of spatial dependency between blocks inside a 64x64 superblock in the rate-distortion optimization loop. Change-Id: I02418c2077efe19adc86e046a6b49364a980f5b1

2013-06-18Merge "Make fdct32 computation flow within 16bit range"Jingning Han
2013-06-18Make fdct32 computation flow within 16bit rangeJingning Han
This commit makes use of dual fdct32x32 versions for rate-distortion optimization loop and encoding process, respectively. The one for rd loop requires only 16 bits precision for intermediate steps. The original fdct32x32 that allows higher intermediate precision (18 bits) was retained for the encoding process only. This allows speed-up for fdct32x32 in the rd loop. No performance loss observed.

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
2013-05-29Merge "further clean-ups on intra4x4 coding" into experimentalJingning Han
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

2013-05-22changes intra coding to be based on txfm blockYaowu Xu
This commit changed the encoding and decoding of intra blocks to be based on transform block. In each prediction block, the intra coding iterates thorough each transform block based on raster scan order. This commit also fixed a bug in D135 prediction code. TODO next: The RD mode/txfm_size selection should take this into account when computing RD values. Change-Id: I6d1be2faa4c4948a52e830b6a9a84a6b2b6850f6

2013-05-21Merge "Initial version of alpha channel support" into experimentalJohn Koleszar
2013-05-20WIP: 4x4 idct/recon mergeScott LaVarnway
This patch eliminates the intermediate diff buffer usage by combining the short idct and the add residual into one function. The encoder can use the same code as well. Change-Id: I296604bf73579c45105de0dd1adbcc91bcc53c22
2013-05-16Initial version of alpha channel supportJohn Koleszar
This is a mostly-working implementation of an extra channel in the bitstream. Configure with --enable-alpha to test. Notable TODOs: - Add extra channel to all mismatch tests, PSNR, SSIM, etc - Configurable subsampling - Variable number of planes (currently always uses all 4) - Loop filtering - Per-plane lossless quantizer - ARNR support This implementation just uses the same contents as the Y channel for the A channel, due to lack of content and general pain in playing back 4 channel content. A later patch will use the actual alpha channel passed in from outside the codec. Change-Id: Ibf81f023b1c570bd84b3064e9b4b8ae52e087592

2013-05-13Change to band calculation.Paul Wilkins
Change band calculation back to simpler model based on the order in which coefficients are coded in scan order not the absolute coefficient positions. With the scatter scan experiment enabled the results were appear broadly neutral on derf (-0.028) but up a little on std-hd +0.134). Without the scatterscan experiment on the results were up derf as well. Change-Id: Ie9ef03ce42a6b24b849a4bebe950d4a5dffa6791
