short-circuit av1_get_tx_scale to always return zero when CONFIG_DAALA_TX, and remove it from the actual Daala TX toplevel This has potential overflow consequences for any metrics computation based on pixels; as such, also force use of the high-bitdepth path in each of these case. subset-1: monty-rest-of-stack-baseline-s1@2017-11-13T00:39:03.881Z -> monty-rest-of-stack-noshift-s1@2017-11-13T14:37:42.541Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 -0.0030 | -0.0523 | 0.2656 | -0.0239 | -0.0033 | -0.0029 | 0.0067 objective-1-fast --limit=4: monty-rest-of-stack-baseline-o1f4@2017-11-13T00:37:06.999Z -> monty-rest-of-stack-noshift-o1f4@2017-11-13T14:37:16.992Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 -0.0264 | 0.2303 | 0.0822 | -0.0109 | -0.0395 | -0.0709 | 0.0538 Change-Id: I57da71861f105dc7a404fa75a75bde573855ef79

Modified the lightfield encoding example to accommodate HW implementation requirements. Fixed the encoding scheme, generated a bitstream of a list of references followed by the surrounding large scale tile coded frames. All large scale tile coded frames use the same uncompressed frame header and the same set of frame contexts. This example also wrote out the frame header and frame contexts while encoding a large scale tile frame and setting EXT_TILE_DEBUG to 1. Change-Id: I7cc19099195d0a20335d5c6bfb9f493f1bf3a7b2

In large scale tile coding(namely, large_scale_tile = 1), forced all frames to generate a bit-exact uncompressed frame header. This patch modified parameters that could change from one frame to another. Change-Id: Ibe72519da0b8a4f5a4ef30a4303ad7d7e4992a65

The numerator in the mv projection can be negative, e.g. cur_to_bwd or cur_to_alt2, since either bwdref or altref2 can be a forward predictive reference, whereas the denominator always stays positive. The rounding inside mv projection hence should use signed operation. Change-Id: I42a105835754a002dd31fcfa7c845e4c105ec54f

This is still a rather inefficient black+white encoder, since it carefully computes some chroma data, but just doesn't write it. However, at least the bitstream is now monochrome. Change-Id: Ie8a89bf329e7b41441032fb0d9e9011385bc12ff

I think the result is a little easier to reason about (you now talk about a property of the block, rather than the behaviour that should be enforced). It also matches the code in read_partition in decodeframe.c Change-Id: I13ba06b1504fa153b8b6b60fa14b373483639718

The "src_height" computed in save_deblock_boundary_lines didn't match the one in save_tile_row_boundary_lines, which meant that the wrapper function assumed the deblock code was saving some lines and that code thought that save_cdef_boundary_lines would do it. This patch fixes up the logic to match, and also completely gets rid of the lines_to_save variable (after all, bad things would happen if lines_to_save was 1 because we'll still read both boundary lines later) The tile height gets rounded up to a multiple of 8 luma pixels in save_tile_row_boundary_lines to avoid nasty corner cases. This will only have any effect for rows at the bottom of the frame (where av1_get_tile_rect clips to the frame boundary). BUG=aomedia:1020 Change-Id: I55adb53fa8ba9c7f97fb2fd5b328a3f2f5065464

The br_cdf and lps_cdf with a new 4-state symbol br_cdf. The br symbol indicates whether the level is k, k+1, k+2 or >k+2 In the latter case, a new br symbol is read. Up to 4 br symbols are read which will reach level 14 at most. Levels greater than 14 are golomb coded. The adapted symbol count is reduced further by this commit. E.g. for the I-frame of ducks_take_off at cq=12, the number of adapted symbols is reduced from 4.27M to 3.85M. About 10% reduction. Gains seems about neutral on a limitied subset.

This experiment modifies lv_map to make use of multi symbol. Replace the nz_map and coeff_base binary CDF with a new multi-symbol CDF of size 4. The new base_cdf indicates for each coeff if the level is 0, 1, 2 or >2. Two new special contexts are added to be used for the last coefficient (the EOB coeff). For the EOB coefficient we already know that it is non-zero. We use one context for DC EOB and one for AC EOB (this can potentially be refined more). The new symbol is read/written by special bitreader/bitwriter functions. Those functions reduce the probability precision from 15bit to 9bit before the invocation of the arithmetic coding engine. The adapted symbol count is significantly reduced by this experiment. E.g. for the I-frame of ducks_take_off at cq=12, the number of adapted symbols is reduced from 6.7M to 4.3M.

Rather than backing out all the LGT-related shifting matrices throughout the existing TX code, separate out and simplify Daala inverse TX into a single dedicated entry point. When DAALA_TX is enabled, CONFIG_HIGHBITDEPTH is also forced, and all of Daala TX (lowbd and highbd) uses this single TX dispatch. This patch is purely non-functional changes. subset 1: monty-TXtesting-fwd-s1@2017-11-12T05:25:09.557Z -> monty-TXtesting-inv-s1@2017-11-12T05:25:43.878Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 0.0000 | 0.0000 | 0.0000 | 0.0000 | 0.0000 | 0.0000 | 0.0000 objective-1-fast: monty-TXtesting-fwd-o1f@2017-11-12T05:25:29.386Z -> monty-TXtesting-inv-o1f@2017-11-12T05:25:58.897Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 0.0000 | 0.0000 | 0.0000 | 0.0000 | 0.0000 | 0.0000 | 0.0000 Change-Id: I790e8d7ac08eb214eb712f5441d6e5f76ebddf17

Reduce context model number from 9 to 6. Let context be two kinds: two reference frames are equal distance or not. Also, give equal distance compound weight {9, 7} instead of {8, 8}/16 Reducing context model gives neutral performance. New compound weight provides -0.14% gain.
