The frame marked as last_bipred at the encoder side is the frame right before the source frame of BWDREF_FRAME, which was not used as a reference. This CL is to add this type of frames to the reference frame buffer and use them as reference for the coding of future frames. This is a non-normative change. A tiny gain is observed (lowres BDRate -0.016% in avg psnr). The main target of this CL is to make it possible to have more flexible gf group structure. For instance, LAST_BIPRED_UPDATE can be replaced by LAST_UPDATE followed by an extra alt ref frame. Change-Id: If3dbce0959bb468e95d01a1feca1dac6bfb91d36

Turn "allow_screen_content_tools" on when the source video has many blocks with only few different colors. The automatic detection is enabled by defualt (or with command line flag "--tune-content=default"). With "--tune-content=screen", the screen content tools are always turned on. On the screen_content test set, the "default" setting is less than 0.3% worse than the "screen" setting on keyframe encoding. Change-Id: Iac7ab8952c96531d1fae84da1823291f5987519c

This patch adds support for 4:1 rectangular blocks to various common data arrays, and adds new partition types to the EXT_PARTITION_TYPES experiment which will use them. This patch has the following restrictions, which can be lifted in future patches: * ext-partition-types is incompatible with fp_mb_stats and supertx for the moment * Currently only 32x32 superblocks can use the new partition types There's a slightly odd restriction about when we allow PARTITION_HORZ_4 or PARTITION_VERT_4. Since these both live in the EXT_PARTITION_TYPES CDF, read_partition() can only return them if both has_rows and has_cols is true. This means that at least half of the width and height of the block must be visible. It might be nice to relax that restriction but that would imply a change to how we encode partition types, which seems already to be in a state of flux, so maybe it's better to wait until that has settled down.

This experiment replaces the 4-point Type-II scaled-output vp9 DCT transform with the 4-point Type-II orthonormal Daala DCT transform. Right now the CONFIG_DAALA_DCT4 experiment depends on CONFIG_DCT_ONLY as it does not add an orthonormal 4-point DST. subset-1: monty-baseline-dctonly-squaretx-subset1 -> monty-dct4-dctonly-squaretx-subset1-rerun PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 0.0055 | -0.0132 | -0.0405 | 0.0261 | 0.0005 | 0.0246 | 0.0226 objective-1-fast: monty-baseline-dctonly-squaretx-o1f -> monty-dct4-dctonly-squaretx-o1f PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 -0.0215 | -0.1573 | N/A | -0.0131 | -0.0347 | -0.0390 | -0.1121 Change-Id: Idef8f6e5525037d5bbb2d0927675c21d1922d69a

Recently, sub8x8 inter mode decition functions have been removed from the av1 codebase, so codebase does not allow disabling cb4x4 anymore. This makes pvq not working simply crashing because we had disabled cb4x4 if pvq is enabled. Hence, pvq has been fixed for cb4x4. Also, if pvq is enabled, disable lgt and highbitdepth in the configure. Change-Id: I2cb675c0dbc12bce60ed6a66c34ea3e907cc35b3

(1) Work with var-refs to remove redundant bits in ref frame coding; (2) Add a new uni-directional compound reference pair: (LAST_FRAME, LAST3_FRAME); (3) Redesign the contexts for encoding uni-directional reference frame pairs; (4) Use aom_entropy_optimizer to collect stats for all the default probability setups related to the coding of reference frames. Compared against the baseline (default enabled tools excluding ext-tx and global-motion for encoder speed concern) with one-sided-compound, the coding gain of ext-comp-refs + var-refs - one-sided-compound is: lowres: avg_psnr -0.385%; ovr_psnr -0.378% ssim -0.344% midres: avg_psnr -0.466%; ovr_psnr -0.447% ssim -0.513% AWCY - High Latency: PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 -0.2758 | -0.1526 | -0.0965 | -0.2581 | -0.2492 | -0.2534 | -0.2118 AWCY - Low Latency: PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 -1.0467 | -1.4500 | -0.9732 | -0.9928 | -1.0407 | -1.0180 | -1.0049 Compared against the baseline (default enabled tools excluding ext-tx and global-motion for encoder speed concern) without one-sided-compound, the coding gain of ext-comp-refs + var-refs - one-sided-compound is: lowres: avg_psnr -0.875%; ovr_psnr -0.877% ssim -0.895% midres: avg_psnr -0.824%; ovr_psnr -0.802% ssim -0.843% Change-Id: I8de774c9a74c20632ea93ccb0c17779fa94431cb

Fixed a bug in my previous patch that causes a compile error (variable block undefined) when pvq is on. However, with or without LGT, --enable-pvq still has a run time error during encoding. This run time error is independent of the LGT experiment. Change-Id: I98ca5f69a916ea8556e45b820c2eb741c9656277

Building with --enable-dct_only will force the encoder to use only tx_type == DCT_DCT.

A python script is provided to accumulate stats from counts.stt files generated from multiple encoding examples. Command line: python ../../tools/aggregate_entropy_stats.py [dir of stats files] [keyword of filenames] [filename of final stats] Plus cosmetics on output format of optimized prob tables. The comma after the last element of each dimension is removed, i.e., before: { { 128, 128, 128, }, { 128, 128, 128, }, } after: { { 128, 128, 128 }, { 128, 128, 128 } }. The reason is to avoid moving '}' to a second line after applying clang-format. Change-Id: I3b764f4c89b7aefbaf48ac00b8c83713caf75a5d
