- If invisible pixels, av1_daala_dist() simply use source pixles for dst. - Added av1_daala_dist_diff() which inputs diff signal instead of dst. - Refactored daala_dist code so that av1_daala_dist() and _diff() is called inside av1's distortion calculation functions, pixel_sse() and sum_squares_visible().

This patch changes the motion vector scaling and clamping to be slightly more accurate (removing an occasional 1px offset due to multiple roundings) and fixes the border clamping when scaling frames. Change-Id: I032dc0b87854eebafa58f1f803981e23c8cc2d9b

Avoids mixing accesses to ctx->pending_cx_data with serialization logic. "index_sz" is deduced from the write position, instead of being redundantly computed. Change-Id: Ic14f93886da61acc1735fbbe4f787e45a4ca79eb

This reverts commit a3d70911. Reason for revert: this was fixed in cb637674 which moved the definition to a different line causing this change to merge cleanly, resulting in a duplicate. Change-Id: I2d8763f0e2af320f043a1417ba33e82f82163592

NCOBMC_ADAPT_WEIGHT allow using different interpolation kernels to combine overlapped predictions generated using mvs in the neighboring blocks. This experiment will build on top of MOTION_VAR and it might conflict with WARPED_MOTION in the developing stage, so will only be effective when MOTION_VAR is on and WARPED_MOTION is off.

The special path in build_inter_predictors for chroma blocks corresponding to sub8x8 luma blocks would always fetch the scale factors from 'xd', which correspond (at least in the decoder) to the references of the block for which is_chroma_reference returns true. The correct behaviour is to fetch the scale factors from 'ref_buf', which corresponds to the references of the block currently being predicted. This patch fixes some encode/decode mismatches which were caused by the above behaviour when the various reference frames had different sizes. Change-Id: I48a0a167ea25d47d08018016cf8b77885b3b5d6b

- First pass encoding time reduces ~10.9% on i7-6700 at 100 frames, 1080p. - avx2 works for coeff number >= 8 cases; coeff number < 8 case will be implemented by sse2. - Unit test is added type B/FP/DC. Change-Id: Ibe5b7807c64e6dfc2d59c470ed50a6e8ca94ef7c

Previously, for block >=8x8, and tx < 8x8, we skipped setting the early-exit flag in block_rd_txfm() because distortion for sub8x8 tx block is from MSE but reference (best) is from daala-dist. However, not setting early-exit flag turned out to be the reason for a regression in MSE probe mode of daala-dist because it loses the chance to set rd_stats properly. On the other hand, there is still a small regression, say 0.05% psnr bd-rate, which seems to occur in the case that a tx block in a partition has chosen the skipped rd_cost since it is smaller than non-skip rd_cost and set the early-exit flag to 0 (so, not exit), but the daala-dist applied to the whole partition cannot access the same info but can choose from two kinds of rd_costs: 1) all tx blocks are skipped (even if a tx block has non-zero coeff) and 0 bits 2) sum of final distortion of all tx blocks (i.e. non-zero coeff decoded) and bits to encode coeffs.

Adds an option bit in the bitstream syntax to allow chroma to have restoration tilesize that is coupled to luma based on subsmapling of the color components. This is meant to ease encoder hardware implementation. Change-Id: Ic3cc2b68c0f33701ed3ff2fe19cf57cd864da67f

cb4x4 itself should not require these sizes. This simplifies compatibility with other experiments, since we can first make them work with cb4x4 (which is now on by default), and then worry about chroma_sub8x8 and chroma_2x2 (which is not) in separate steps. Encoder and decoder output should remain unchanged. Change-Id: Iff2a5494cab3b7d96f881e8bd9cd4bf18c817cfa

When writing the compressed header, prob_diff_update() was called for compound_type_prob[] for every defined block size, even though luma never uses block sizes smaller than 4x4. This fixes is_any_masked_compound_used() and is_interinter_compound_used() to properly return 0 for chroma-only block sizes, and then uses these functions to guard the probability updates in write_compressed_header() and read_compressed_header(), the same way the actual compound type values are guarded in read_inter_block_mode_info() and pack_inter_mode_mvs().

Without tempmv-signaling configured, using the previous frame's MVs requires that the last frame was a show frame. With tempmv-signaling configured, cm->show_last_frame is not checked when calculating use_prev_frame_mvs. This patch adds that check and resolves mismatches seen with random resizing and random superres. Includes a couple fixes too - cm's last_width, last_height, and last_show_frame were updated under different conditions. Now they're all updated at the same time.
