c8f4c187b3 Use consistent range for VP8E_SET_NOISE_SENSITIVITY
Accept the same range of inputs for the VP8E_SET_NOISE_SENSITIVITY
control, regardless of whether temporal denoising is enabled or not.
This is important for maintaining compatibility with existing
applications.

22f56b93e5 Formalize encodeframe.c forward delclarations
Change If4321cc5 fixed a bug caused by forward declarations not being
kept in sync across C files, resulting in a function call with the
wrong arguments. The commit moves the affected function declarations
into a header file, along with the other symbols from encodeframe.c
that were being sloppily shared.

f039a85fd8 Make global data const
Removes all runtime initialization of global data. This commit is a
squashed version of the following series cherry-picked from master.
This is necessary because of a change that was merged to the tester
that depends on the scaler being moved to the RTCD framework, which
is a worthwhile thing to include in Eider anyway.

25a36d6b3c multi-res: restore v1.0.0 API
Move the notion of 0 bitrate implying skip deeper into the codec,
rather than doing it at the multi-encoder API level. This preserves
v1.0.0 ABI compatibility, rather than forcing a bump to v2.0.0 over a
minor change. Also, this allows the case where the application can
selectively enable and disable the larger resolution(s) without having
to reinitialize the codec instace (for instance, if no target is
receiving the full resolution stream).

It's not clear how deep to push this check. It may be valuable to
allow the framerate adaptation code to run, for example. Currently put
the check as early as possible for simplicity, should reevaluate this
as this feature gains real use.

3f252e30e4 Modified ARNR MC-filter to ignore ARF frame
The ARNR filter uses MC to find the best match between the
ARF and other nearby frames in the filter-set. Since the
ARF is a member of the filter-set, MC in that case is
unnecesssary. This patch modifies the filter so it does
not apply MC in this case.

f0605f4b7e Removed MV costing from ARNR filtering
The ARNR filter uses a motion compensated temporal filter,
but the motion estimation implementation accounts for the
cost of the mv in its decision making process. The ARNR
filter uses a dummy cost table initialized to 0 as a way
to ignore the mv costs (which are irrelevant to the filter).

This CL modifies the ARNR filter implementation so that
the mv costing is ignored without the requirement for
dummy tables.

24e7b1b90d Moves error concealment allocations from common parts to decoder
The backup MODE_INFO buffer used in the error concealment was
allocated in the codec common parts allocation even though this is a
decoder only resource. Moved the allocation to the decoder side.
No need to update_mode_info_border as mode_info buffers are zero
allocated.

This fixes also a potential memory leak as the EC overlaps buffer was not
properly released before reallocation after a frame size change.

3939e85b26 Fix loopfilter race condition in multithreaded encoder
Race was introduced by https://gerrit.chromium.org/gerrit/15563.

If loopfilter related config params were changed between frames, or
after a KEY frame, there could be a mismatch between encoder's and
decoder's recontructed image. In worst case, when frame buffers are
reallocated because of a size change, the loopfilter could
do an invalid data access (segmentation fault).

Fixes:
Sync with the loopfilter before applying any encoder changes in
vp8_change_config().
Moved the loopfilter synching to the top of
encode_frame_to_data_rate() so that it's done before any alteration of
the encoder.

b41c17d625 Shares one set of RD costs tables between all encoding threads
RD costs were local to MACROBLOCK data and had to be copied all the
time to each thread's MACROBLOCK data. Tables moved to a common place
and only pointers are setup for each encoding thread.

vp8_cost_tokens() generates 'int' costs so changed all types to be
int (i.e. removed unsigned).

NOTE: Could do some more cleaning in vp8cx_init_mbrthread_data().

When producing an invisible ARF, the time stamp counters aren't

prior code was trapping this case with refresh_alt_ref, but this isn't
correct for other uses of the ARF. Instead, use the show_frame flag.

6b33ca395f Fixes to disable MFQE when there is motion.
This patch includes:
1. fixes to disable block based termporal mixing when motion
is detected (because this version of mfqe only handles zero motion).
2. The criterion used for determining whether to mix or
not are changed to use squared differences rather than
absolute differences.
3. Additional checks on color mismatch and excessive block
flatness added. If the block as decoded has very low activity
it is unlikely to yield benefits for mixing.

8106df8f5a MFQE: apply threshold to subblocks and chroma.
In cases where you have a flat background occluded by a moving object
of similar luminosity in the foreground, it was likely that the
foreground blocks would persist for a few frames after the background
is uncovered. This is particularly noticable when the object has a
different color than the background, so add the chroma planes in as an
additional check.

In addition, for block sizes of 8 and 16, the luma threshold is
applied on four subblocks independently, which helps when only part of
the background in the block has been uncovered.

This fixes issue #392, which includes a test clip to reproduce the
issue.

52cf4dcaea Packing bitstream on-the-fly with delayed context updates
Produce the token partitions on-the-fly, while processing each MB.
Context is updated at the beginning of each frame based on the
previoud frame's counters. Optimally encoder outputs partitions in
separate buffers. For frame based output, partitions are concatenated
internally.

Limitations:
    - enabled just in combination with realtime-only mode
    - number of encoding threads has to be equal or less than the
    number of token partitions. For this reason, by default the encoder
    will do 8 token partitions.
    - vpxenc supports partition output (-P) just in combination with
    IVF output format (--ivf)

Performance:
    - Realtime encoder can be up to 13% faster (ARM) depending on the number
    of threads and bitrate settings. Constant gain over the 5-16 speed
    range.
    - Token buffer reduced from one frame to 8 MBs

Quality:
    - quality is affected by the delayed context updates. This again
    dependents on input material, speed and bitrate settings. For VC
    style input the loss seen is up to 0.2dB. If error-resilient=2
    mode is used than the effect of this change is negligible.

Example:
./configure --enable-realtime-only --enable-onthefly-bitpacking
./vpxenc --rt --end-usage=1 --fps=30000/1000 -w 640 -h 480
--target-bitrate=1000 --token-parts=3 --static-thresh=2000

019384f2d3 Only do uv intra-mode evaluation when intra mode is checked
When we encode slide-show clips, for the majority of the time,
only ZEROMV mode is checked, and all other modes are skipped.
This change delayed uv intra-mode evaluation until intra mode is
actually checked. This gave big performance gain for slide-show
video encoding (2nd pass gain: 18% to 28%). But, this change
doesn't help other types of videos.

Also, zbin_mode_boost is adjusted in mode-checking loop, which
causes bitstream mismatch before/after this change when --best
or --good with --cpu-used=0 are used.

507ee87e3e Remove the frame rate factor for key frame size.
When temporal layers is used (i.e., number_of_layers > 1),
we don't use the frame rate boost for setting the key
frame target size. The factor was forcing the target size to be
always at its minimum (2* per_frame_bandwidth) for low frame rates
(i.e., base layer frame rate).

Generally we should modify or remove this frame rate factor;
for now we turn if off for number_of_layers > 1.

mode_info_context->mbmi.mb_skip_coeff has to always reflect the
existence or not of coeffs for a certain MB. The loopfilter needs this
info.
mb_skip_coeff is either set by the vp8_tokenize_mb or has to be set to
1 when the MB is skipped by mode selection. This has to be done
regardless of the mb_no_coeff_skip value.

prob_skip_false is needed just when mb_no_coeff_skip is 1. No need to
keep count of both skip_false and skip_true as they are complementary
(skip_true+skip_false = total_mbs)

e8223bd250 decoder: reset segmentation map on keyframes
Refactoring some of the mode decoding logic introduced a bug where
the segmentation maps would not be properly reset on keyframes.

http://code.google.com/p/webm/issues/detail?id=378

The text of the bug is somewhat misleading as I initially read it to
imply the bug was present in v0.9.7-p1 (Cayuga), but note the text
"master", which indicates this was something subsequent. This issue
bisects back to v0.9.7-p1-84-ga99c20c, so unfortunately it was broken
during the Duclair release.

Thanks to Alexei Leonenko for investigating the root cause.

Second shot at this...

Sync with loopfilter thread as late as possible, usually just at the
beginning of next frame encoding. This returns control to application
faster and allows a better multicore scaling.

When PSNR packets are generated the final filtered frame is needed
imediatly so we cannot delay the sync. Same has to be done when
internal frame is previewed.

fea3556e20 Fix variance overflow
In the variance calculations the difference is summed and later squared.
When the sum exceeds sqrt(2^31) the value is treated as a negative when
it is shifted which gives incorrect results.

To fix this we cast the result of the multiplication as unsigned.

The alternative fix is to shift sum down by 4 before multiplying.
However that will reduce precision.

For 16x16 blocks the maximum sum is 65280 and sqrt(2^31) is 46340 (and
change).

PPC change is untested.

fa1a9290e6 Allow to skip highest-resolution encoding in multi-resolution encoder
Sometimes, a user doesn't have enough bandwidth to send high-resolution
(i.e. HD) video even though the camera catches HD video. This change
allowed users to skip highest-resolution encoding by setting that level's
target bit rate to 0.

To test it, modify the following line in vp8_multi_resolution_encoder.c.
    unsigned int  target_bitrate[NUM_ENCODERS]={1400, 500, 100};
To skip the highest-resolution level, change it to
    unsigned int  target_bitrate[NUM_ENCODERS]={0, 500, 100};
To skip the first and second highest resolution levels, change it to
    unsigned int  target_bitrate[NUM_ENCODERS]={0, 0, 100};

This change also fixed a small problem in mapping, which slightly helped
quality and performance.

a910049aea New RTCD implementation
This is a proof of concept RTCD implementation to replace the current
system of nested includes, prototypes, INVOKE macros, etc. Currently
only the decoder specific functions are implemented in the new system.
Additional functions will be added in subsequent commits.

Overview:
  RTCD "functions" are implemented as either a global function pointer
  or a macro (when only one eligible specialization available).
  Functions which have RTCD specializations are listed using a simple
  DSL identifying the function's base name, its prototype, and the
  architecture extensions that specializations are available for.

Advantages over the old system:
  - No INVOKE macros. A call to an RTCD function looks like an ordinary
    function call.
  - No need to pass vtables around.
  - If there is only one eligible function to call, the function is
    called directly, rather than indirecting through a function pointer.
  - Supports the notion of "required" extensions, so in combination with
    the above, on x86_64 if the best function available is sse2 or lower
    it will be called directly, since all x86_64 platforms implement
    sse2.
  - Elides all references to functions which will never be called, which
    could reduce binary size. For example if sse2 is required and there
    are both mmx and sse2 implementations of a certain function, the
    code will have no link time references to the mmx code.
  - Significantly easier to add a new function, just one file to edit.

Disadvantages:
  - Requires global writable data (though this is not a new requirement)
  - 1 new generated source file.

Commit 892e23a5b introduced support for the VP8D_GET_LAST_REF_USED,
but missed the mapping of the control id to the underlying function,
so it was unavailable to applications.

In addition, the underlying function vp8_references_buffer() is
moved from common/postproc.c to decoder/onyxd_if.c as postproc.c is
not built in all configurations.

83cef816fd Correct clamping in use of vp8_find_near_mvs()
Commit e06c242ba introduced a change to call vp8_find_near_mvs() only
once instead of once per reference frame by observing that the only
effect that the frame had was on the bias applied to the motion
vector. By keeping track of the sign_bias value, the mv to use could
be flip-flopped by multiplying its components by -1.

This behavior was subtley wrong in the case when clamping was applied
to the motion vectors found by vp8_find_near_mvs(). A motion vector
could be in-bounds with one sign bias, but out of bounds after
inverting the sign, or vice versa. The clamping must match that done
by the decoder.

This change modifies vp8_find_near_mvs() to remove the clamping from
that function. The vp8_pick_inter_mode() and vp8_rd_pick_inter_mode()
functions instead track the correctly clamped values for both bias
values, switching between them by simple assignment. The common
clamping and inversion code is in vp8_find_near_mvs_bias()

630d3b95e2 Revert "Multithreaded encoder, late sync loopfilter"
This commit is incomplete, as it does not synchronize the loop filter
before returning a handle to the reconstructed frame in
vpx_codec_get_preview_frame(), which can cause (false?) failures
when running the test_reconstruct_buffer test.

This may be related to a bug that does cause visible artifacts, which
is also under investigation.

This reverts commit 380d64ecb1.

Makes the thresholds for the multiframe quality enhancement module
depend on the difference between the base quantizers. Also modifies
the mixing function to weigh the current low quality frame less if
the difference in quantizer is large. With the above modifications
mfqe works well for both scalable patterns as well as low quality
key frames.

e479379abb Fixed bugs in multi-layer code related to changing params
When running multi-layer (ML) encodes and dynamically
changing coding parameters on the fly (e.g. frame
duration/rate, bandwidths allocated to each layer)
the encoder would not produce sensible output.

In certain cases the rate targeting would be
hideously inaccurate.

These fixes make it possible to change these coding
parameters correctly and to maintain accurate control
of the rate targeting.

I also added the specification of the input timebase
into the test program, vp8_scalable_patterns.c.

2a0d7b1a55 Reduce the default kf_max_dist to 128.
The default maximum keyframe interval is 9999, or over five minutes
at normal video rates. When the encoder produces streams with such
a long interval seeking (with correct output) is more expensive,
and live streaming is impossible.

Of course the encoding application should set this parameter
based on its knowledge of the intended use of the stream, but
reducing the default gives better results for applications
which do not.
