This is added as part of ALT_INTRA experiment.
This uses interpolation between top row and estimated bottom row; as
well as left column and estimated right column to generate the
predicted block.The interpolation is done using a predefined weight
array.
Based on experiments, the currently chosen weight array was created
to represent a quadratic curve, but can be tuned further if needed.
Improvement from baseline on Derf set:
ALL Keyframes: 1.279%
Improvement from existing ALT_INTRA:
ALL Keyframes: 1.146%

This commit adds an experiment to interleave the coding of transform
coefficients from YUV planes. The experiment can be enabled at config
time by --enable-coef-interleave.

This is currently just a refactor and creates no change in performance.
It allows new compound types to be added easily in the future to
facilitate experiments with segmentation masks.

After https://aomedia-review.googlesource.com/#/c/5589/ ,
the Global_Motion_Params and GLOBAL_MOTION_TYPE types
are redundant, and can be removed in favour of
WarpedMotionParams and TransformationType respectively.

This commit supports the recursive transform block partition to
start with both square and rectangular transform block sizes.

This CL doesn't change any coding behavior.
The functions modified in this CL include
choose_smallest_tx_size()
choose_largest_tx_size()
choose_tx_size_type_from_rd()
txfm_rd_in_plane()
txfm_yrd()
This change make the code cleaner and will facilitate rd_debug
implementation
Change-Id: I19b1b2384dce8b46b28d4c9baf80ff92998d05b6
* changes:
Merge rd_stats only when it is valid
Let parentheses in handle_inter_mode be symmetric
Add RD_STATS into MB_MODE_INFO
Add txb_coeff_cost_map
Since PVQ's max block size equals to the max transform size,
daala's definition of OD_BSIZE_MAX was changed from 5 down to 4 to
use AV1's max trasform size 32x32. However, dering also uses
OD_BSIZE_MAX and assumes its value is 5, which caused dering
not working.

PVQ replaces the scalar quantizer and coefficient coding with a new
design originally developed in Daala. It currently depends on the
Daala entropy coder although it could be adapted to work with another
entropy coder if needed:
./configure --enable-experimental --enable-daala_ec --enable-pvq
The version of PVQ in this commit is adapted from the following
revision of Daala:
fb51c1ade6
More information about PVQ:
- https://people.xiph.org/~jm/daala/pvq_demo/
- https://jmvalin.ca/papers/spie_pvq.pdf
The following files are copied as-is from Daala with minimal
adaptations, therefore we disable clang-format on those files
to make it easier to synchronize the AV1 and Daala codebases in the future:

Known issues:
- Lossless mode is not supported, '--lossless=1' will give the same result as
'--end-usage=q --cq-level=1'.
- High bit depth is not supported by PVQ.

With RD_STATS in MB_MODE_INFO, we will be able to compare the results
from rate-distortion loop and the results from bitstream packing.

This is just partial implementation
Compare token cost of pack_mb_tokens/pack_txb_tokens with token cost
from rate-distortion loop. If there is any difference, dump out mode
info.

- Const correctness
- Refactoring
- Make variables local when possible etc
- Remove -Wcast-qual to allow explicitly casting away const.
Cherry-picked from aomedia/master: c27fcccc
And then a number of more const correctness changes to make sure other
experiments build OK.

This flag was already added to aomedia/master, so bringing it back to
webm/nextgenv2, as part of an effort to get the two codebases in sync.
Change-Id: I2b933a6a160e4210d1411a9e7978149eb8553205
To get ready for pulling AV1 to nextgenv2
Replace the experimental flag by MOTION_VAR. Rename major variables.
Change-Id: If6cf4f37b9319c46d8f90df551cc7295d66ca205
Refactor to streamline the number of profiles needed, in
preparation for the next steps.
NO change in performance.
Change-Id: I753b89299897857f3c250c316b4cdc4fedcb90e8
Disable rect_tx because we only support 4x4 Walsh-Hadamard transform
in lossless mode.
Fixes failure in ./test_libaom --gtest_filter=*Large*ScreencastQ0/1

this matches style guidelines and stabilizes successive runs of
clang-format across the tree. remaining types should be address in
successive commits.

Uses an array to map block sizes, y tx sizes, and subsampling
