We leave it in rdopt.c as a local define for now - this can be removed
later. In all other places, we remove it, thereby slightly decreasing
the size of some arrays in the bitstream.

Change-Id: Ic2a9beb97a4eda0b086f62c039d994b192f99ca5

It remains as a local define in rdopt.c so we can distinguish between
split and non-split modes in the RD loop, but disappears outside that
scope in the codec.

Change-Id: I98c18fe5ab7e4fbd1d6620ec5695e2ea20513ce9

Also merge all counters. This removes a few unused probability updates
from the bitstream.

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.

This commit makes clean-ups in the rate-distortion loop for 4x4,
4x8, and 8x4 block sizes for the use of iterative motion search.

Removed unnecessary use of bmi in handle_inter_mode.

Deprecated loop over labels in the 4x4/4x8/8x4 block rd search.

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: Ic40d56fb162f4e201547dfae33e62ccd9e865889

Adding API to read/write uncompressed frame header bits (it is not final
yet). Separate functions to read/write uncompressed header. Moving
clr_type, error_resilient_mode, refresh_frame_context,
frame_parallel_decoding_mode, frame_context_idx from compressed partition
to uncompressed frame header.

Fixes a build issue due to removal of VP9_KF_BINTRAMODES macro,
when ENTROPY_STATS is on.

Change-Id: I75c61702bf626376c942ab49ab887714b43284f0

Uses reduced arrays for probabilities and branch counts in the
encoder. No change in bitstream.

This commit pulls the iterative motion search for compound inter-
inter out from handle_inter_mode_ as a separate function. Hence,
it is applicable to 4x4/4x8/8x4 level compound inter search to be
enabled later.

Also edit the rd loop for 4x4 inter block sizes for cosmetic
purpose.

Change-Id: Ibc71a11cbe5a26cd52faba01026cf8446cf4d2b4

Removed one 4x4 prediction step that was unnessary in the rd loop.
Removed a unused modecosts estimate from encoder side.

1. remove prediction mode conversion
2. unified bmode, same for key and non-key frame
3. set I4X4_PRED count for pdf to 0, as I4X4_PRED is no longer
coded ever. It is determined by ref_frame and block partition

Saves 1 add, 3 shifts (and a shift bias) per 1-D transform.

This commit removes the use of bmi_ in the first-pass encoding by
forcing encode_intra4x4block_ to use DC_PRED, followed by DCT_DCT
only, as John suggested. This makes the need for bmi buffer only
up to 4 entries, instead of 16.

Hardware implementation needs to load coeff probs based on the
transform size. For selectable transform size, moving these bits
earlier in the bitstream adds some delay giving time to preload
the probs and speeds up the decoding process.

Change-Id: I3bfc1f662ae6f219c9286fe9ae6310c7d8a63ea7

Also do per-partition motion vector referencing in <sb8x8 partitions,
and adjust mvref finding for sub8x8 partitions.

1) Added an initialization of rd_tx_select_threshs[].
2) Made updating transform size counts to be consistent

rate-distortion loop.

This commit refactors the iterative motion search for compound
inter-inter mode, to make it support all partition types including
4x4/4x8/8x4 block sizes.

Change-Id: I2213229dfe852001dfec16b149f47c52ce88f3aa

Move 4x4/4x8/8x4 partition coding out of experimental list.

This commit fixed the unit test failure issues. It also resolved
the merge conflicts between 4x4 block level partition and iterative
motion search for comp_inter_inter.

Change-Id: I898671f0631f5ddc4f5cc68d4c62ead7de9c5a58

Added SSE2 version of variance functions for super blocks.

Change-Id: Ibeaae8771ca21c99d41dd74067574a51e97b412d

Reverts to using 128 bit LUT for the coef models rather than 48
to ease hardware implementation.

Also incorporates some cleanups including removing various
hooks to support different lookup tables based on block_type and
ref_type.

Change-Id: I54100c120cca07a2ebd3a7776bc4630fa6a153f6

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: I536f7f125a4ff5149bb3a64f791e835c324535fd

This commit allows the rate-distortion optimization of intra coding
capable of supporting 8x4 and 4x8 partition settings.

It enables the entropy coding of intra modes in key frame using a
unified contextual probability model conditioned on its above/left
prediction modes.

The API is not final yet and can be changed. Actual layout of
uncompressed frame part will be finalized later. Right now moving
clr_type, error_resilient_mode, refresh_frame_context,
frame_parallel_decoding_mode from first compressed partition to
uncompressed frame part.
