This patch does not seem to give any benefits.

Change-Id: I9d2b4091d6af3dfc0875f24db86c01e2de57f8db

Adds an experiment that codes an end-of-orientation symbol
for every eligible zero encountered in scan order.

This cleans out various other sub-experiments that were part
of the origiinal patch, which will be later included if found
useful.

Results are slightly positive on all sets (0.1 - 0.2% range).

Change-Id: I57765c605fefc7fb9d1b57f1b356843602abefaf

Removes the redundant dst pointers from vp9_build_inter_predictors_sb{y,uv}
and the remaining mb specific functions.

Change-Id: I7b6bf439d9394b85ea79b4fe61a3ffc1025720da

First in a series of commits moving the framebuffers pointers to
per-plane data, so that they can be indexed numerically rather than
by name.

This experiment has failed to give much benefit but
does add complexity so deprecated.

Change-Id: Ia6722bc26f34ae7fc5cb15e491aba39d2f20a85b

Use in-place buffers (dst of MACROBLOCKD) for  macroblock prediction.
This makes the macroblock buffer handling consistent with those of
superblock. Remove predictor buffer MACROBLOCKD.

Change-Id: Id1bcd898961097b1e6230c10f0130753a59fc6df

Moving all the probability updates after frame context selection.
This makes it clean and simple to store all the probs in single
struct that can be sent to hardware codec.

Change-Id: I2ec3de81adbd468d8ef34a914caae80a18c3ef56

Removed skip_recon_sb(). Cleanup code so that we could combine
decode_sb and decode_mb later.

Change-Id: I24d1dd5283e2565072838a03c344938b88bfd35c

Also moving frame size check into read_frame_size function.

Change-Id: Ib098d83bd50081bfc2941c87aea0dc58cb39583e

List of moved functions: vp9_decode_uniform, vp9_decode_term_subexp,
vo9_inv_recenter_nonneg, vp9_decode_unsigned_max.

Change-Id: Ib518beb90b791690c5c93de17b8bdbf560033b41

Also using ALLOWED_REFS_PER_FRAME instead of 3.

Change-Id: I810dd8521d8138edb9dbd78edede49b62f706554

Enable recursive partition information coding from SB64X64 down to
MB16X16. The bit-stream syntax is now supporting rectangular block
sizes. It starts from SB64X64 and recursively describes the partition
type of the current block. If the partition type is PARTITION_NONE,
the block is coded as a single unit; if it is PARTITION_HORZ or
PARTITION_VERT, the block is segmented into two independently coded
rectangular units, with no further partition needed; otherwise, the
block is segmented into 4 square blocks. i.e., PARTITION_SPLIT case,
each can be potentially further partitioned.

Forward adaptive probability modeling is used for the partition
information coding, conditioned on the current block size.

New names are y_dc_delta_q, uv_dc_delta_q, uv_ac_delta_q.

Change-Id: I4acae1fc23a4697ce2c5a5becb8dc28ef0a4b552

This flag was added to VP8 to allow a mode where MB-level skipping
was not allowed, saving a bit per mb. It was never used in practice,
and hasn't been tested in VP9, so remove it.

Change-Id: Id450ec6904c6d06c1919508e7efc52d05cde5631

tx_type == DCT_DCT check is an implementation detail of iht_add. Also
adding dequant_add_y function with explicit DCT_DCT check inside.

Change-Id: Ia3cb0225601752cdef0ff6f0acd3a09d9dbd8938

This is the first CL with vp9_reader changes. All another macro
definitions will be replaced after.

Change-Id: I1c6bd9c9a612ec1663d484d6adb4fb720af54063

Now that the predictor is the dest, we do not need the
extra parameters.

Change-Id: I78db73d39b5aff62f15303f3d51ad2797eae74b6

Combine superblock inter predictors into a unified function that
allows configurable block width and height. The inter predictions
of block sizes smaller than 16x16 are handled differently. To be
continued on merging them later.

Change-Id: I14075959dd5e221f00c205c99ca35c1c31ef728e

So it is consistent with I8x8_PRED.

Change-Id: Iefa65124b2419690d83e526c611129c0ede29d11

The intra predictor supports configurable block sizes. It can handle
intra prediction down to 4x4 sizes, when enabled in BLOCK_SIZE_TYPE.

This patch changes the default with the modecoefprob expt
to use mode-based forward updates with one-node pegged
modeling.

The maximum difference with fully trained tables is now
less that 0.1%.

Change-Id: I06b44322e10c6703f93f3c1d48d973b1136a0618

This patch will use the dest buffer instead of the
predictor buffer.  This will allow us in future commits
to remove the extra mem copy that occurs in the dequant
functions when eob == 0.  We should also be able to remove
extra params that are passed into the dequant functions.

Change-Id: I7241bc1ab797a430418b1f3a95b5476db7455f6a

Use sb-common version instead.

Change-Id: If2552b5a39fd2e5272f66a41c5667dda85fd3939

With these fixed, the codec produces identical results regardless of
what literal values are used for the enum members in BLOCK_SIZE_*.

Change-Id: I26db8e08019b58ba432af1f0950ebe6b0eb4ad8c

The unified dequantization, inverse transform, and adding functions
support rectangular block sizes. Also separate the operations on
luma and chroma components, in the consideration of the txfm_size
for uv components in rectangular block sizes.

Change-Id: I2a13246b2a9086b37d575d346070990d854cc110

Unify the sb32x32 and sb64x64 decoding units, which also allow for
other rectangular block sizes.

Change-Id: Ia5187ab2af56f98c3f99272bdf4dbcabe798ad5d

Merge sb32x32 and sb64x64 functions; allow for rectangular sizes. Code
gives identical encoder results before and after. There are a few
macros for rectangular block sizes under the sbsegment experiment; this
experiment is not yet functional and should not yet be used.

Change-Id: I1c356e5f886deb3f8807dc212de9799b55b09d58

Adding ALLOWED_REFS_PER_FRAME constant instead of hard coded number 3.

Change-Id: I46146aa837896936f920c748c7d4aa4c27f026e4

removing redundant code.

Change-Id: Ifc5cc9863897925ea2a7cab4f7309ccf28d80bfe
