In order to understand memory layout consider the declaration of the
following structs. The first one is a part of our API:
struct vpx_codec_ctx {
// ...
struct vpx_codec_priv *priv;
};
The second one is defined in vpx_codec_internal.h:
struct vpx_codec_priv {
// ...
};
The following struct is defined 4 times for encoder/decoder VP8/VP9:
struct vpx_codec_alg_priv {
struct vpx_codec_priv base;
// ...
};
Private data allocation for the given ctx:
struct vpx_codec_ctx *ctx = <get>
struct vpx_codec_alg_priv *alg_priv = <allocate>
ctx->priv = (struct vpx_codec_priv *)alg_priv;
The cast works because vpx_codec_alg_priv has a
vpx_codec_priv instance as a first member 'base'.

Allow for an option to selectively apply the deblocking loop filter to the denoised
raw block, based on the denoised state (no-filter, filter with zero motion, or filter with non-zero motion)

In the current logic, if the sse for zero motion is smaller
than the sse for new_mv (i.e., best_sse), we may still end up
using the non-zero mv for denoising (if the magnitude of new_mv is above threshold).
This can happen for very noisy content, and can lead to artifacts.
This change ensures that we always use zero_mv (over new_mv) for
denoisng if sse_zero_mv <= best_sse.

If the denoiser filter causes too big a change in the absolute pixel difference
(between source and denoised signal), the block is not denoised, which can cause
visual block artifacts. This change applies a second adjustment to the temporal filter
to effectively allow for a (weaker) denoising for such blocks (which can keep
the absolute differnence within the tolerance range in most cases).
This helps to reduce some of the block artifacts from the denoising.
The additional cost of re-applying the filter to this set of blocks is low,
as the percentage of blocks per frame (with too big a change in absolute pixel difference)
is typically small, 2-5%.

As a side-effect, the max_sad check is removed from the

That will make the VP8 C implementation of sad a little slower
but given that is rarely used in practice, the impact will be

This patch did a cleanup following the commit "Save NEON registers

The recent compiler can generate optimized code that uses NEON registers

Adds a new end-usage option for constant quality encoding in vpx. This
first version implemented for VP9, encodes all regular inter frames
using the quality specified in the --cq-level= option, while encoding
all key frames and golden/altref frames at a quality better than that.
The current performance on derfraw300 is +0.910% up from bitrate control,
but achieved without multiple recode loops per frame.
The decision for qp for each altref/golden/key frame will be improved
in subsequent patches based on better use of stats from the first pass.
Further, the qp for regular inter frames may also be varied around the
provided cq-level.

This is work-in-progress, it implements multiple ARF
encoding behind an experimental flag.
It adds the ability to insert multiple ARF frames into a
single ARF group. This patch implements the reordering
of the coded frames, and implements a fixed-length coding
pattern. It applies a fixed quantizer strategy based on
where the frame is in the coding sequence.
Further work to modify the rate control strategy is
ongoing and will be submitted via a set of future patches.
In this first step, each ARF group is recursively
bisected and an ARF frame added at that position in the
sequence. The recursion continues until ARF frames are
within MIN_GF_INTERVAL frames.
The code sits behind the "multiple-arf" experimental
flag ("CONFIG_MULTIPLE_ARF"). The experimental flag
"oneshotq" ("CONFIG_ONESHOTQ") also needs to be enabled
for this patch to work correctly.

Writing all #define guards using the same style. Inlining macro
VP8DX_BOOL_DECODER_FILL into vp8dx_bool_decoder_fill. Removing unnecessary
includes.

Remove dependency of this function on asm_offsets. ssse3/sse4 next.
Change quant_shift calculation so it be done using SIMD. Pre-calculate
as much as possible to simplify EOB selection.
Take advantage of qcoeff being zero'd by tying the if statements
together.
Speed parity with previous implementation with gcc x86_64 linux

Reduce dependency on offsets file by using intrinsics. Disassembly shows
improvements over previous assembly specifically in register management,
preloading, and {pro,epi}log. Speed change is within margin of error.

Started adding support for multiple internal decoder instances. Also added
code to limit the vp8 config options available when using frame-based
multithreading.

Adds a flag to disable features that would inhibit frame parallel
decoding. This includes backward adaptation and MV sorting based
on search in ref frame buffer.
Also includes some minor clean-ups.

When error concealment is enabled, it swaps the mi and prev_mi ptrs after
each frame is decoded. The postproc uses the mi ptr for the mode info context.
Now the postproc will use the correct mode info context.

Reduce the delta loop filter for blocks that are cyclicly refreshed.
This helps to reduce the dot artifacts that may happen
when zero_mv blocks are repeatedly loop-filtered.
This change, along with the fix in:
https://gerrit.chromium.org/gerrit/#/c/40409/
helps to reduce this artifact, but cannot remove the dot artifacts completely.

Use the proper seg/mode/ref filter offsets when selecting the
frame loop filter level for fast mode (pick_filter_level_fast).

The MAX_PSNR was used to assign a "psnr" number when the mse is close
to zero. The direct assignment is used to prevent divide by zero in
computation. Changing it from 60 to 100 to be consistent against what
is being done in VP9

WIP: Fixing unsafe threading in VP8 encoder.
Use the passed in macroblock instead of the macroblock located in
cpi.

The loopfilter thread from the previous frame can be running while
starting the current frame. cpi->Source will change during this time causing
the wrong data to be copied. The refresh_x_frame flags also change, which
will cause incorrect updates of the denoised buffers.
Change-Id: I7d982b4fcb40a0610801332aa85f3b792c64e4c3
The denoiser was writing to LAST_FRAME buffer. If LAST_FRAME isn't being
updated, the reference frame buffers were out of sync between the encoder and the
denoised raw buffers. This patch resolves the discrepancy by always writing to a work
buffer (INTRA_FRAME) and then copying from that buffer to any buffers that needs to
be updated.

Multi-threaded code was not updated to disable background
refresh for non base-layer frames at the time it was
disabled in the main C-code.

Don't use the switch to gf_rate_correction factor when
temporal layers is used (i.e., cpi->oxcf.number_of_layers > 1).
In temporal layers, we prefer to avoid this as any frame
(e.g., base layer frame at anchor of pattern) may update
both last and golden (and possibly alt-ref), and so we would get
different rate correction factors within the same layer.
This change will make sure one rate correction factor exists for each layer.
Also, made some other code in qp-regulate that depends on
alt/golden update specific to the 1 layer case.

Rather than building an object file directory heirarchy matching the
source tree's layout, rename the object files so that the object
file name contains the path in the source file tree. The intent here
is to allow two files in different parts of the source tree to have
the same name and still not collide when put into an ar archive.

Creates a merge between the master and experimental branches. Fixes a
number of conflicts in the build system to allow *either* VP8 or VP9
to be built. Specifically either:
$ configure --disable-vp9 $ configure --disable-vp8
--disable-unit-tests
VP9 still exports its symbols and files as VP8, so that will be
resolved in the next commit.
Unit tests are broken in VP9, but this isn't a new issue. They are
fixed upstream on origin/experimental as of this writing, but rebasing
this merge proved difficult, so will tackle that in a second merge
commit.

Most of these were picked up by jenkins in the commit that changed
the vp8 namespace to vp9 in common/.

For non-static functions, change the prefix to vp9_. For static functions,
remove the prefix. Also fix some comments, remove unused code or unused
function prototypes.

Most of these were picked up in the previous commit (prefix change from
vp8_ to vp9_), but I'm pushing this separately so that it's easier to
review.

Converted the forward and inverse transforms to integer forms.
Modify #define TEST_INT 1/0
in the code to call integer/float version of transforms.
The tests showed that average OVERALL PSNR loss was less than 0.1%.

As suggested by Paul, this commit separate the subpel refmv selection
into a separate experiment. It also changed a couple variable names
to better reflect the nature of the variables.
