4c14efd234 Fix checks in MB quantizer initialization
vp8cx_mb_init_quantizer() needs to be called at least once to get
all values calculated. This change added one check to decide if
we could skip initialization or not.

9dc95b0a12 Added check to make sure maximum buffer size not exceeded
Added code to clip the buffer level to the maximum buffer
size. Without this the buffer level would increase
unchecked.

This bug was found when encoding an essentially static
scene at 2Mb/s. The encoder is unable to generate frames
consistent with the high data-rate because Q bottoms out
at Qmin.

As frames generated are consistently undersized the buffer
level increases and does not get checked against the
maximum size specified by the user (or default).

1427205215 Changing decoder input partition API to input fragments.
Adding support for several partitions within one input fragment.
This is necessary to fully support all possible packetization
combinations in the VP8 RTP profile. Several partitions can
be transmitted in the same packet, and they can only be split
by reading the partition lengths from the bitstream.

9bf3bc9a72 Correct SPLITMV clamping
Prior to this fix, the clamping state of the last subblock partition
dominated, whereas the correct behavior is to clamp if any partition
needs clamping. This bug was introduced by v0.9.6-232-g6b25501

88e24f07ae added code to clear 2nd order block when appropriate
It is discovered that in rare situations the 2nd order block may
produce a few small magnitude coefficients that has no effect on
reconstruction. The situations are a combination of low quantizer
values (high quality) and low energy in residual signals (content
dependent). This commit added code to detect such cases and reset
the 2nd order block to all 0.

Patch 1 to 4 used code to do all-zero-check on idct result buffer,
and tests on derf set showed a consistent gain of .12%-.14% on all
metrics.But due to a recent change Ie31d90b, the idct result buffer
is not longer populated. So patch 5&6 use an alternative method to
detect the situations. Tests on derf set now shows a consistent
quality gain of .16%-.20%.

As suggested by Jim, Patch 7&8 removed the condition of all first
order block not having any coefficient, instead we reset 2nd order
coefficients to all 0 if sum of absolute value of the coefficients
is small. So it does slightly more than just detecting the oddity
as discussed above, but tests on derf set now show a consistent
gain of .20%-.23% on all metrics.

It is worth noting here that this change does not have any effect
on mid/high quantizer range, it only affects the quantizer value
18 or blow. Within this range, the change helps compression by up
to 2.5% on clips in the derf set.

3556deaca3 combine loopfilter data access
The data processed by the loopfilter overlaps. At the block level, this
results in some redundant transforms. Grouping the filtering allows for
a single 16x16 transpose (and inversion) instead of three 16x8 transposes
(and three more inversions).

This implementation is x86_64 only. We retain the previous
implementation for x86.

Improvements are obviously material dependant, but it seems to be ~%1 in
tests here.

e529a825f7 Fix necessary for input partitions iface to match the RTP profile
These changes fixes a glitch between the RTP profile and the input
partitions interface. Since there's no way for the user to know the
actual number of partitions, the decoder have to read the
multi_token_paritition bits also when input partitions mode is
enabled.

Included are also a couple of fixes for issues with independent
partitions and uninitialized memory reads.

The data that the simple horizontal loopfilter reads is aligned, treat

For the vertical, we only use the bottom 4 bytes, so don't read in 16

This shows a small improvement on older processors which have a
significant penalty for unaligned reads.

4e8d35a461 Copy less when active map is in use
When active map is specified and the current frame is not a key frame,
golden frame nor a altref frame then copy only those active regions.

This significantly reduces encoding time by as much as 19% on the test
system where realtime encoding is used. This is particularly useful
when the frame size is large (e.g. 2560x1600) and there's only a few
action macroblocks.

In sub-pixel motion search, the search range is small(+/- 3 pixels).
Preload whole search area from reference buffer into a 32-byte

instead. This keeps data in cache, and reduces the crossing cache-
line penalty. For tulip clip, tests on Intel Core2 Quad machine(linux)

data access latency is greatly reduced in newer cores.

Next, I will apply similar idea to other 2 sub-pixel search functions
for encoding speed > 4.

Make this change exclusively for x86 platforms.

7d1b37cdac Increase chrow row alignment to 16 bytes.
This is done by expanding luma row to 32-byte alignment, since
 there is currently a bunch of code that assumes that
 uv_stride == y_stride/2 (see, for example, vp8/common/postproc.c,
 common/reconinter.c, common/arm/neon/recon16x16mb_neon.asm,
 encoder/temporal_filter.c, and possibly others; I haven't done a
 full audit).
It also uses replaces the hardcoded border of 16 in a number of
 encoder buffers with VP8BORDERINPIXELS (currently 32), as the
 chroma rows start at an offset of border/2.
Together, these two changes have the nice advantage that simply
 dumping the frame memory as a contiguous blob produces a valid,
 if padded, image.

b5ea2fbc2c Improved 1-pass CBR rate control
This patch attempts to improve the handling of CBR streams with
respect to the short term buffering requirements. The "buffer level"
is changed to be an average over the rc buffer, rather than a long
running average. Overshoot is also tracked over the same interval
and the golden frame targets suppressed accordingly to correct for
overly aggressive boosting.

Testing shows that this is fairly consistently positive in one
metric or another -- some clips that show significant decreases
in quality have better buffering characteristics, others show
improvenents in both.

11694aab66 Change to arf boost calculation.
In this commit I have added an experimental function
that tests prediction quality either side of a central position
to calculate a suggested boost number for an ARF frame.

The function is passed an offset from the current position and
a number of frames to search forwards and backwards.
It returns a forward, backward and compound boost number.

The new code can be deactivated using #define NEW_BOOST 0

In its current default state the code searches forwards and backwards
from the proposed  position of the next alt ref.

The the old code used a boost number calculated by scanning forward
from the previous GF up to the proposed alt ref frame position.

I have also added some code to try and prevent placement of a gf/arf
where there is a brief flash.

7296b3f922 New ways of passing encoded data between encoder and decoder.
With this commit frames can be received partition-by-partition
from the encoder and passed partition-by-partition to the
decoder.

At the encoder-side this makes it easier to split encoded
frames at partition boundaries, useful when packetizing
frames. When VPX_CODEC_USE_OUTPUT_PARTITION is enabled,
several VPX_CODEC_CX_FRAME_PKT packets will be returned
from vpx_codec_get_cx_data(), containing one partition
each. The partition_id (starting at 0) specifies the decoding
order of the partitions. All partitions but the last has
the VPX_FRAME_IS_FRAGMENT flag set.

At the decoder this opens up the possibility of decoding partition
N even though partition N-1 was lost (given that independent
partitioning has been enabled in the encoder) if more info
about the missing parts of the stream is available through
external signaling.

Each partition is passed to the decoder through the
vpx_codec_decode() function, with the data pointer pointing
to the start of the partition, and with data_sz equal to the
size of the partition. Missing partitions can be signaled to
the decoder by setting data != NULL and data_sz = 0. When
all partitions have been given to the decoder "end of data"
should be signaled by calling vpx_codec_decode() with
data = NULL and data_sz = 0.

The first partition is the first partition according to the
VP8 bitstream + the uncompressed data chunk + DCT address
offsets if multiple residual partitions are used.

e3f850ee05 Avoid text relocations in ARM vp8 decoder
The current code stores pointers to coefficient tables and loads them to
access the tables contents. As these pointers are stored in the code
sections, it means we end up with text relocations. eu-findtextrel will
thus complain about code not compiled with -fpic/-fPIC.

Since the pointers are stored in the code sections, we can actually cheat
and let the assembler generate relative addressing when accessing the
coefficient tables, and just load their location with adr.

Further testing shows that the overshoot accumulation/damping is too

But some clips show significant overshoot in the buffer window, so
I think this still needs work.
