"<< SUBPEL_BITS" needs to be added in the calculation. Call
set_scaled_offsets() to calculate x_offset_q4 and y_offset_q4.

It is enough to check just block type: intra or inter. Intra block implies
intra prediction mode, and inter block implies inter mode.

replaces use of cur_tile_mi_(row|col)_(start|end) by VP9_COMMON, making
it less stateful and more reusable for parallel tile decoding

Restructured the storing of loopfilter information. Deleted
loop_filter_info struct and reduced copying happened in every
superblock.
Tests showed a 0.5% ~ 0.8% decoder speed gain.

update_partition_context / partition_plane_context: this will allow for
separate storage to be used in tile decoding

When only upper-left 8x8 area has non-zero dct coefficients, we
could skip 1D IDCT for 9th to 32th rows to save operations. This
function is called when eob <= 34.

For consistency with idct function names. Renames:
vp9_short_fdct4x4 -> vp9_fdct4x4
vp9_short_walsh4x4 -> vp9_fwht4x4

Assign the pointer to mode_info stream per tile. Remove the use of
tile_col in the decoding modules.

The ref's scale_factors are set at frame level, and then copied for
each partition block. Since the struct members are mostly constant,
this patch separated the constant and non-constant members, and
reduced struct copying. This gave 0.5% ~ 1.4% decoder speed gain.

This commit uses left_available flag to decide if the left mode_info
struct is available for left_block_mode. As discussed with James
Zern (jzern@), this prevents the codec from fetching mode_info from
blocks in the left tile, which although effectively not used might
present concerns for multi-threaded tile decoding.
This is NOT a bit-stream change.
Change-Id: I1dc8cf1bcbf056688eee27c7bc5706ac4b4e0125
Simple modification to reduce number of cycles in the
function.
Original function number of cycles: 973
Modified function number of cycles: 835
Improvment factor: 1.165

This reverts commit a82001b1cf, reversing
changes made to f6d870f7ae.
This commit breaks windows builds and needs some work to fix those and
some additional comments.

Just making fdct consistent with iht/idct/fht functions which all use
stride (# of elements) as input argument.
Change-Id: I0ba3c52513a5fdd194f1e7e2901092671398985b
We used set_partition_seg_context() only before calls to:
1. update_partition_context()
2. partition_plane_context()
Moving these functions from vp9_blockd.h to vp9_onyxc_int.h and
inlining set_partition_seg_context into them. After that it is not
necessary to have {above, left}_seg_context fields in MACROBLOCKD struture,
so removing them also.
Change-Id: I4723f59e1c8f3788432b7f51185d8d747b3a97f9
Renames for consistency with other constants:
NUM_FRAME_TYPES -> FRAME_TYPES
NUM_PARTITION_CONTEXTS -> PARTITION_CONTEXTS
Change-Id: I3db30acb2868eb0a424237c831087b2e264ec47f
This patch fixed a bug that caused 32bit PIC build mismatch. The
stack pointer was modified after "GET_GOT". Loading left pointer
from a hard-coded position gave wrong result.

Commit "d207 intra prediction ssse3 using bytes" caused mismatch
while building 32bit PIC code. Disabled these SSSE3 functions
until we fix the bug.

in most cases at least the left column was a harmless race as it was
left unused later in the code.

That makes decoder and encoder (only bitstream writing part) a little bit
simpler and faster. Moving get_sb_index() function to the encoder.

* changes:
Use a separate MODE_INFO stream for each tile column
Get rid of "this_mi", use "mi_8x8[0]" everywhere instead
Make the static_segmentation feature work again
The only case where they were intentionally pointing to different
structures was in mbgraph, and this didn't have the expected behavior
because both of these pointers are used interchangeably through the code
Change-Id: I979251782f90885fe962305bcc845bc05907f80c
Moving code that gets band_translate array from get_scan_and_band()
function to get_band_translate() function. Renaming get_scan_and_band() to
get_scan().
Change-Id: I43047c205a1ca2a6e24be44db39dc04b7a385008
Updated the encoder to handle frames that are coded
intra-only. Intra-only frames must be non-showable,
that is, the "show frame" flag must be set to 0 in
the frame header.
Tested by forcing the ARF frames to be coded intra-
only.
Note: The rate control code will need to be modified
to account for intra-only frames better than they
are currently handled.

Remove the semicolon in the definition of vp9_zero macro. Make all
the use cases of vp9_zero of consistent format.

Values of MODE_UPDATE_PROB and VP9_COEF_UPDATE_PROB are equal, so replacing
them with one constant. Inlining appropriate arguments for functions:
vp9_cond_prob_diff_update (encoder)
vp9_diff_update_prob (decoder)

We have two SSE2-optimized functions for idct4_1d:
vp9_idct4_1d_sse2 <-- removing this one
idct4_1d_sse2
vp9_idct4_1d_sse2 was used only by the following functions which already
have SSE2 optimized variants:
vp9_idct4x4_16_add_c -> vp9_idct4x4_16_add_see2
idct8_1d -> vp9_idct8x8_{16, 10, 1}_see2
vp9_short_iht4x4_add_c -> vp9_short_iht4x4_add_see2
Change-Id: Ib0a7f6d1373dbaf7a4a41208cd9d0671fdf15edb
To ensure fast encoding/decoding on devices without ssse3 support,
SSE2 optimization of sub-pixel filters was done. Test using 1080p
clip showed the decoder speeds were ~70fps with ssse3 filters, ~60fps
with sse2 filters, and ~15fps with c filters.

snprintf is not supported by MSVC, the commit replace it with the msvc
variant _snprintf to enable build.

When all coefficients are zeros, skip the corresponding 1-D inverse
transform. This practice has been used in the SSE2 implementation of
inverse 32x32 DCT. This commit imports this algorithm into the C code.
Change-Id: I0f58bfcb183a569fab85d524d5d9cf8ae8653f86
We already have itxm_add member in MACROBLOCKD structure. Both
inv_txm4x4_1_add and inv_txm4x4_add are just its special cases for
different eob values. But eob logic is already implemented in
vp9_iwht4x4_add and vp9_idct4x4_add (that's why also removing
inverse_transform_b_4x4_add).
