The ALT_REF_FRAME is now updated in the case of a KEY_FRAME in the VP9 denoiser.

Change-Id: Idf9a9772706f50e774fb240afcc01db38841043c

Separates HBD profile int two profiles (2 and 3) consistent with the
highbitdepth branch. This patch is ported from the original highbitdepth
branch patch: https://gerrit.chromium.org/gerrit/#/c/70460/

Two of the invalid file tests needed to be updated.

The bug sets the wrong pointer to the first pass mb stats
if the encoder does the re-coding in the second pass.

Change-Id: I8a11f45dd7dceb38de814adec24cecccae370d00

This patch is the first step toward simplifying the
frame buffer handling.

The final goal is to have a common frame buffer handling
framework for both encoder and decoder that incorporates
the existing ability to use externally allocated memory.

This commit changed the hard-coded DEFAULT_INTERP_FILTER to a speed
feature with the same default value: SWITCHABLE.

On a Nexus 7, vpxenc (in realtime mode, speed -6)
reported a performance improvement of ~17%.

2 pass only change to calculation of rd mult based on Q.
Make a small adjustment based on frame type and also
replace adjustment based on iifactor with an one based
on the ambient GF/ARF boost level.

Also fix multi arf bug / issue.

Overall these change give an slight improvement in ssim
but hurt psnr a little.

We target this speed to achieve similar encoding speed and better
compression than vp8 rt mode with cpu-used at -12.

Change-Id: Ic1bb4371c81a17ea80e83459c1cbf4c09a3498e8

In vp8, statistics are collected about the different modes as they are searched.
This process is more complicated due to the variable block size. Fields were
added to the PICM_MODE_CONTEXT struct to hold this information for each point in
the search. The information is then taken from the appropriate part of the tree
during denoising.

Change-Id: I196535aee81a8967551c058849d7f9c6874cb730

All changes are for spatial svc only.
1. Enable encoding hidden frames in each layer and use alt reference idex to reference the hidden frame in each layer
2. Use golden reference idx for spatial reference
3. For those layers that don't have hidden frames (caused by lack of frame buffers), reference a hidden frame in lower layers
4. Add "auto-alt-refs" in svc options

This commit fixes a potential out-of-boundary memory access due to
the use of reuse_inter_pred_sby in the non-RD coding flow. It
resolves the corresponding asan error.

Change-Id: Iff605f5921230966990013541cd855d698810922

This commit fixes a mismatched use case of block size in non-RD
intra prediction check. The residual SSE and variance should be
calculated per transform block size, instead of operating block
size, which caused chrome valgrind warning on conditional jump
based on uninitialized value (webm issue 823). This commit
resolves this issue.

Change-Id: I595c06599c7e0fd0e4a08736519ba68fc14bc79a

Refactoring to remove some duplication of probability
tables between tokenization and detokenization.

Change-Id: I3d9130e726a1299fd258f6dfe93315e2d12f76da

Changed to use defined inline functions consistently through
the code.

Change-Id: I7644d24fa7a837378564a6e0790416d3725dd200

Use a weaker filter for second level arf frames.
Average gain across all sets and metrics ~0.3%

Remove code for arnr_type which is no longer
supported in VP9 which always uses a centered blur.

Re-factor and some cleanup.

Currently, vp9_diamond_search_sadx4() is only called when sse3 is
enabled, which is improper since sse2 optimization of sdx4df
functions are available. Changed to always use
vp9_diamond_search_sadx4().

Change-Id: I4b95d6b7a3c6c645783c373f0ba8d645ece24717

There are sse2 optimization of sdx4df functions. Instead of calling
vp9_refining_search_sadx4 only when sse3 is enabled, call it always.

Deleted vp9_find_best_sub_pixel_comp_tree(), and combined it in
vp9_find_best_sub_pixel_tree().

Change-Id: Ifb25763c8b19822df5537cc1daa76ce88dc3b056

Use FAST_HEX in speed 5 and 6, which covers more points than
FAST_DIAMOND and improves motion search quality.

At speed 6, RTC set borg tests showed slight quality gain (psnr
gain: 0.143%, ssim gain: 0.226%). No noticeable encoding speed
change.

This commit combined the full pel and sub pel motion search into a
single function to avoid code duplication. The commit does not change
encoder outputs.

This commit enables a new quantization process for 32x32 2D-DCT
transform coefficient blocks. It improves the compression
performance of speed 5 by 1.4%. The overall compression gains of
speed 5 due to the new quantization scheme is 4.7%. It also includes
the SSSE3 implementation of the 32x32 quantization process.

In the previous version, only certain buffers in the macroblockd were saved and
the restored. In this version, all of the buffers are saved and restored. The
code was then rolled into a loop for readability.

Also contains a tiny fix for when the -DOUTPUT_YUV_DENOISED flag is used.

* Replace max_step_search_steps with constant MAX_MVSEARCH_STEPS
* Fold (reduce_first_step_size + speed > 5) into reduce_first_step_size
  replacing uses of reduce_first_step_size that don't add the speed
  check with zero.

vp9_rdopt is for making rd optimal mode decisions. vp9_rd is for all
other rd related routines. Anything used outside of making an rd optimal
decision belongs in rd.

Moved the threshold adjustment before reference flag checking,
which could set the threshold to INT_MAX for disabled reference
frame, and cause overflow if the adjustment is done after that.

Change-Id: I85e94f8726d5e3ae93f65965aa978721dddc9957

Renamed updating_running_avg() to filter(). Extended function with the rest of
the filter procedure. Made all of the empirically-determined constants used in
VP8 into functions so they can be tweaked more easily.

Change-Id: I41730c8c92370c76885950a43742347477ca4e7e

As in VP8.

Currently, this parameter is set with the VP8E_SET_NOISE_SENSITIVITY flag.
The flag was not renamed so that we don't break the interface for webrtc. This
should probably be changed at some point in the future.

Adapt the use of segmentation in AQ mode 2 based on
the ambient kf/arf/gf Q.

Disable segmentation where the rate per SB is very
low and overheads are likely to outweigh the benefits.

This patch reduces the -ve average metrics impact
of AQ mode 2 while allowing stronger 3 segment AQ
in some cases. Average improvement ~0.5-1.0%.
