/*Adjust a single corner of a set of metric bins to minimize the squared
prediction error of R and D.
Each bin is assumed to cover a quad like so:
(s0,q0) (s1,q0)
A----------B
| |
| |
| |
| |
C----------Z
(s0,q1) (s1,q1)
The values A, B, and C are fixed, and Z is the free parameter.
Then, for example, R_i is predicted via bilinear interpolation as
x_i=(s_i-s0)/(s1-s0)
y_i=(q_i-q0)/(q1-q0)
dRds1_i=A+(B-A)*x_i
dRds2_i=C+(Z-C)*x_i
R_i=dRds1_i+(dRds2_i-dRds1_i)*y_i
To find the Z that minimizes the squared prediction error over i, this can
be rewritten as
R_i-(A+(B-A)*x_i+(C-A)*y_i+(A-B-C)*x_i*y_i)=x_i*y_i*Z
Letting X={...,x_i*y_i,...}^T and
Y={...,R_i-(A+(B-A)*x_i+(C-A)*y_i+(A-B-C)*x_i*y_i),...}^T,
the optimal Z is given by Z=(X^T.Y)/(X^T.X).
Now, we need to compute these dot products without actually storing data for
each sample.
Starting with X^T.X, we have
X^T.X = sum(x_i^2*y_i^2) = sum((s_i-s0)^2*(q_i-q0)^2)/((s1-s0)^2*(q1-q0)^2).
Expanding the interior of the sum in a monomial basis of s_i and q_i gives
s0^2*q0^2 *(1)
-2*s0*q0^2*(s_i)
-2*s0^2*q0*(q_i)
+q0^2 *(s_i^2)
+4*s0*q0 *(s_i*q_i)
+s0^2 *(q_i^2)
-2*q0 *(s_i^2*q_i)
-2*s0 *(s_i*q_i^2)
+1 *(s_i^2*q_i^2).
However, computing things directly in this basis leads to gross numerical
errors, as most of the terms will have similar size and destructive
cancellation results.
A much better basis is the central (co-)moment basis:
{1,s_i-sbar,q_i-qbar,(s_i-sbar)^2,(s_i-sbar)*(q_i-qbar),(q_i-qbar)^2,
(s_i-sbar)^2*(q_i-qbar),(s_i-sbar)*(q_i-qbar)^2,(s_i-sbar)^2*(q_i-qbar)^2},
where sbar and qbar are the average s and q values over the bin,
respectively.
In that basis, letting ds=sbar-s0 and dq=qbar-q0, (s_i-s0)^2*(q_i-q0)^2 is
ds^2*dq^2*(1)
+dq^2 *((s_i-sbar)^2)
+4*ds*dq*((s_i-sbar)*(q_i-qbar))
+ds^2 *((q_i-qbar)^2)
+2*dq *((s_i-sbar)^2*(q_i-qbar))
+2*ds *((s_i-sbar)*(q_i-qbar)^2)
+1 *((s_i-sbar)^2*(q_i-qbar)^2).
With these expressions in the central (co-)moment bases, all we need to do
is compute sums over the (co-)moment terms, which can be done
incrementally (see oc_mode_metrics_add() and oc_mode_metrics_merge()),
with no need to store the individual samples.
Now, for X^T.Y, we have
X^T.Y = sum((R_i-A-((B-A)/(s1-s0))*(s_i-s0)-((C-A)/(q1-q0))*(q_i-q0)
-((A-B-C)/((s1-s0)*(q1-q0)))*(s_i-s0)*(q_i-q0))*(s_i-s0)*(q_i-q0))/
((s1-s0)*(q1-q0)),
or, rewriting the constants to simplify notation,
X^T.Y = sum((C0+C1*(s_i-s0)+C2*(q_i-q0)
+C3*(s_i-s0)*(q_i-q0)+R_i)*(s_i-s0)*(q_i-q0))/((s1-s0)*(q1-q0)).
Again, converting to the central (co-)moment basis, the interior of the
above sum is
ds*dq*(rbar+C0+C1*ds+C2*dq+C3*ds*dq) *(1)
+(C1*dq+C3*dq^2) *((s_i-sbar)^2)
+(rbar+C0+2*C1*ds+2*C2*dq+4*C3*ds*dq)*((s_i-sbar)*(q_i-qbar))
+(C2*ds+C3*ds^2) *((q_i-qbar)^2)
+dq *((s_i-sbar)*(r_i-rbar))
+ds *((q_i-qbar)*(r_i-rbar))
+(C1+2*C3*dq) *((s_i-sbar)^2*(q_i-qbar))
+(C2+2*C3*ds) *((s_i-sbar)*(q_i-qbar)^2)
+1 *((s_i-sbar)*(q_i-qbar)*(r_i-rbar))
+C3 *((s_i-sbar)^2*(q_i-qbar)^2).
You might think it would be easier (if perhaps slightly less robust) to
accumulate terms directly around s0 and q0.
However, we update each corner of the bins in turn, so we would have to
change basis to move the sums from corner to corner anyway.*/

These are placed here instead of on the stack so that they can persist

only a few non-zero coefficients were decoded.
It requires at least 65 elements because the zig-zag index array uses the
65th element as a dumping ground for out-of-range indices to protect us
from buffer overflow.
We make it fully twice as large so that the second half can serve as the
reconstruction buffer, which saves passing another parameter to all the
acceleration functios.
It also solves problems with 16-byte alignment for NEON on ARM.
gcc (as of 4.2.1) only seems to be able to give stack variables 8-byte
alignment, and silently produces incorrect results if you ask for 16.
Finally, keeping it off the stack means there's less likely to be a data
hazard beween the NEON co-processor and the regular ARM core, which avoids
unnecessary stalls.*/

/*Instead of storing every branching in the tree, subtrees can be collapsed
into one node, with a table of size 1<<nbits pointing directly to its
descedents nbits levels down.
This allows more than one bit to be read at a time, and avoids following all
the intermediate branches with next to no increased code complexity once
the collapsed tree has been built.
We do _not_ require that a subtree be complete to be collapsed, but instead
store duplicate pointers in the table, and record the actual depth of the
node below its parent.
This tells us the number of bits to advance the stream after reaching it.
This turns out to be equivalent to the method described in \cite{Hash95},
without the requirement that codewords be sorted by length.
If the codewords were sorted by length (so-called ``canonical-codes''), they
could be decoded much faster via either Lindell and Moffat's approach or
Hashemian's Condensed Huffman Code approach, the latter of which has an
extremely small memory footprint.
We can't use Choueka et al.'s finite state machine approach, which is
extremely fast, because we can't allow multiple symbols to be output at a
time; the codebook can and does change between symbols.
It also has very large memory requirements, which impairs cache coherency.
We store the tree packed in an array of 16-bit integers (words).
Each node consists of a single word, followed consecutively by two or more
indices of its children.
Let n be the value of this first word.
This is the number of bits that need to be read to traverse the node, and
must be positive.
1<<n entries follow in the array, each an index to a child node.
If the child is positive, then it is the index of another internal node in
the table.
If the child is negative or zero, then it is a leaf node.
These are stored directly in the child pointer to save space, since they only
require a single word.
If a leaf node would have been encountered before reading n bits, then it is
duplicated the necessary number of times in this table.
Leaf nodes pack both a token value and their actual depth in the tree.
The token in the leaf node is (-leaf&255).
The number of bits that need to be consumed to reach the leaf, starting from
the current node, is (-leaf>>8).

/*A node in the Huffman tree.
Instead of storing every branching in the tree, subtrees can be collapsed
into one node, with a table of size 1<<nbits pointing directly to its
descedents nbits levels down.
This allows more than one bit to be read at a time, and avoids following all
the intermediate branches with next to no increased code complexity once
the collapsed tree has been built.
We do _not_ require that a subtree be complete to be collapsed, but instead
store duplicate pointers in the table, and record the actual depth of the
node below its parent.
This tells us the number of bits to advance the stream after reaching it.
This turns out to be equivalent to the method described in \cite{Hash95},
without the requirement that codewords be sorted by length.
If the codewords were sorted by length (so-called ``canonical-codes''), they
could be decoded much faster via either Lindell and Moffat's approach or
Hashemian's Condensed Huffman Code approach, the latter of which has an
extremely small memory footprint.
We can't use Choueka et al.'s finite state machine approach, which is
extremely fast, because we can't allow multiple symbols to be output at a
time; the codebook can and does change between symbols.
It also has very large memory requirements, which impairs cache coherency.

/*Super blocks are 32x32 segments of pixels in a single color plane indexed
in image order.
Internally, super blocks are broken up into four quadrants, each of which
contains a 2x2 pattern of blocks, each of which is an 8x8 block of pixels.
Quadrants, and the blocks within them, are indexed in a special order called
a "Hilbert curve" within the super block.
In order to differentiate between the Hilbert-curve indexing strategy and
the regular image order indexing strategy, blocks indexed in image order
are called "fragments".
Fragments are indexed in image order, left to right, then bottom to top,
from Y' plane to Cb plane to Cr plane.
The co-located fragments in all image planes corresponding to the location
of a single quadrant of a luma plane super block form a macro block.
Thus there is only a single set of macro blocks for all planes, each of which
contains between 6 and 12 fragments, depending on the pixel format.
Therefore macro block information is kept in a separate set of arrays from
super blocks to avoid unused space in the other planes.
The lists are indexed in super block order.
That is, the macro block corresponding to the macro block mbi in (luma plane)
super block sbi is at index (sbi<<2|mbi).
Thus the number of macro blocks in each dimension is always twice the number
of super blocks, even when only an odd number fall inside the coded frame.
These "extra" macro blocks are just an artifact of our internal data layout,
and not part of the coded stream; they are flagged with a negative MB mode.*/

From 0ae66d565e6bead8604d312bc1a4e9dccf245c88 Mon Sep 17 00:00:00 2001
From: Tim Terriberry <tterribe@xiph.org>
Date: Tue, 8 May 2012 02:51:57 +0000
Subject: [PATCH] Fix pp_sharp_mod calculation.
This was broken when the dequant_tables indexing changed in commit
r16102, but it only affected post-processing quality, so we never
noticed.
With gcc 4.8.0, this can now trigger a segfault during decoder
initialization.

/*Super blocks are 32x32 segments of pixels in a single color plane indexed
in image order.
Internally, super blocks are broken up into four quadrants, each of which
contains a 2x2 pattern of blocks, each of which is an 8x8 block of pixels.
Quadrants, and the blocks within them, are indexed in a special order called
a "Hilbert curve" within the super block.
In order to differentiate between the Hilbert-curve indexing strategy and
the regular image order indexing strategy, blocks indexed in image order
are called "fragments".
Fragments are indexed in image order, left to right, then bottom to top,
from Y' plane to Cb plane to Cr plane.
The co-located fragments in all image planes corresponding to the location
of a single quadrant of a luma plane super block form a macro block.
Thus there is only a single set of macro blocks for all planes, each of which
contains between 6 and 12 fragments, depending on the pixel format.
Therefore macro block information is kept in a separate set of arrays from
super blocks to avoid unused space in the other planes.
The lists are indexed in super block order.
That is, the macro block corresponding to the macro block mbi in (luma plane)
super block sbi is at index (sbi<<2|mbi).
Thus the number of macro blocks in each dimension is always twice the number
of super blocks, even when only an odd number fall inside the coded frame.
These "extra" macro blocks are just an artifact of our internal data layout,
and not part of the coded stream; they are flagged with a negative MB mode.*/

*
* The functions documented here are actually subdivided into three
* The functions documented here are divided between two
* separate libraries:
* - <tt>libtheoraenc</tt> contains the encoder interface,
* - \c libtheoraenc contains the encoder interface,
* described in \ref encfuncs.
* - <tt>libtheoradec</tt> contains the decoder interface and
* routines shared with the encoder.
* You must also link to this if you link to <tt>libtheoraenc</tt>.
* The routines in this library are described in \ref decfuncs and
* \ref basefuncs.
* - <tt>libtheora</tt> contains the \ref oldfuncs.
* - \c libtheoradec contains the decoder interface,
* described in \ref decfuncs, \n
* and additional \ref basefuncs.
*
* New code should link to <tt>libtheoradec</tt> and, if using encoder
* features, <tt>libtheoraenc</tt>. Together these two export both
* the standard and the legacy API, so this is all that is needed by
* any code. The older <tt>libtheora</tt> library is provided just for
* compatibility with older build configurations.
* New code should link to \c libtheoradec. If using encoder
* features, it must also link to \c libtheoraenc.
*
* In general the recommended 1.x API symbols can be distinguished
* by their <tt>th_</tt> or <tt>TH_</tt> namespace prefix.
* The older, legacy API uses <tt>theora_</tt> or <tt>OC_</tt>
* prefixes instead.
* During initial development, prior to the 1.0 release,
* \c libtheora exported a different \ref oldfuncs which
* combined both encode and decode functions.
* In general, legacy API symbols can be indentified
* by their \c theora_ or \c OC_ namespace prefixes.
* The current API uses \c th_ or \c TH_ instead.
*
* While deprecated, \c libtheoraenc and \c libtheoradec
* together export the legacy api as well at the one documented above.
* Likewise, the legacy \c libtheora included with this package
* exports the new 1.x API. Older code and build scripts can therefore
* but updated independently to the current scheme.

coefficients we decoded for this block.
It contains the value of zzi BEFORE the final token in the block was
decoded.
In most cases this is an EOB token (the continuation of an EOB run from a
previous block counts), and so this is the same as the coefficient count.
However, in the case that the last token was NOT an EOB token, but filled
the block up with exactly 64 coefficients, _last_zzi will be less than 64.
Provided the last token was not a pure zero run, the minimum value it can
be is 46, and so that doesn't affect any of the cases in this routine.
However, if the last token WAS a pure zero run of length 63, then _last_zzi
will be 1 while the number of coefficients decoded is 64.
Thus, we will trigger the following special case, where the real
coefficient count would not.
Note also that a zero run of length 64 will give _last_zzi a value of 0,
but we still process the DC coefficient, which might have a non-zero value
due to DC prediction.
Although convoluted, this is arguably the correct behavior: it allows us to
use a smaller transform when the block ends with a long zero run instead
of a normal EOB token.
It could be smarter... multiple separate zero runs at the end of a block
will fool it, but an encoder that generates these really deserves what it
gets.
Needless to say we inherited this approach from VP3.*/

/*Converts DCT coefficients from transposed order into zig-zag scan order and
stores them in %[y].
This relies on two macros to load the contents of each row:
OC_ZZ_LOAD_ROW_LO(row,"reg") and OC_ZZ_LOAD_ROW_HI(row,"reg"), which load
the first four and second four entries of each row into the specified
register, respectively.
OC_ZZ_LOAD_ROW_LO must be called before OC_ZZ_LOAD_ROW_HI for the same row
(because when the rows are already in SSE2 registers, loading the high half
destructively modifies the register).
The index of each output element in the original 64-element array should wind
up in the following 8x8 matrix (the letters indicate the order we compute
each 4-tuple below):
A 0 8 1 2 9 16 24 17 B

/*Converts DCT coefficients from transposed order into zig-zag scan order and
stores them in Y.
This relies on two macros to load the contents of each row:
OC_ZZ_LOAD_ROW_LO(row,reg) and OC_ZZ_LOAD_ROW_HI(row,reg), which load the
first four and second four entries of each row into the specified register,
respectively.
OC_ZZ_LOAD_ROW_LO must be called before OC_ZZ_LOAD_ROW_HI for the same row
(because when the rows are already in SSE2 registers, loading the high half
destructively modifies the register).
The index of each output element in the original 64-element array should wind
up in the following 8x8 matrix (the letters indicate the order we compute
each 4-tuple below):
A 0 8 1 2 9 16 24 17 B
C 10 3 4 11 18 25 32 40 E
F 33 26 19 12 5 6 13 20 D

N 23 31 38 45 52 59 60 53 J

The order of the coefficients within each tuple is reversed in the comments
below to reflect the usual MSB to LSB notation.*/
