libtheora 1.1.1 (2009 October 1)
- Fix problems with MSVC inline assembly
- Add the missing encoder_disabled.c to the distribution
- build updates: autogen.sh should work better after switching systems
and the MSVC project now defaults to the dynamic runtime library
- Namespace some variables to avoid conflicts on wince.
libtheora 1.1.0 (2009 September 24)
- Fix various small issues with the example and telemetry code
- Fix handing a zero-byte packet as the first frame
- Documentation cleanup
- Two minor build fixes
libtheora 1.1beta3 (2009 August 22)
- Rate control fixes to smooth quality
- MSVC build now exports all of the 1.0 api
- Assorted small bug fixes
libtheora 1.1beta2 (2009 August 12)
- Fix a rate control problem with difficult input
- Build fixes for OpenBSD and Apple Xcode
- Examples now all use the 1.0 api
- TH_ENCCTL_SET_SPLEVEL works again
- Various bug fixes and source tree rearrangement
libtheora 1.1beta1 (2009 August 5)
- Support for two-pass encoding
- Performance optimization of both encoder and decoder
- Encoder supports dynamic adjustment of quality and
bitrate targets
- Encoder is generally more configurable, and all
rate control modes perform better
- Encoder now accepts 4:2:2 and 4:4:4 chroma sampling
- Decoder telemetry output shows quantization choice
and a breakdown of bitrate usage in the frame
- MSVC assembly optimizations up to date and functional
libtheora 1.1alpha2 (2009 May 26)
- Reduce lambda for small quantizers.
- New encoder fDCT does better on smooth gradients
- Use SATD for mode decisions (1-2% bitrate reduction)
- Assembly rewrite for new features and general speed up
- Share code between the encoder and decoder for performance
- Fix 4:2:2 decoding and telemetry
- MSVC project files updated, but assembly is disabled.
- New configure option --disable-spec to work around toolchain
detection failures.
- Limit symbol exports on MacOS X.
- Port remaining unit tests from the 1.0 release.
libtheora 1.1alpha1 (2009 March 27)
- Encoder rewrite with much improved vbr quality/bitrate and
better tracking of the target rate in cbr mode.
- MSVC project files do not work in this release.
libtheora 1.0 (2008 November 3)
- Merge x86 assembly for forward DCT from Thusnelda branch.

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
dequantize fewer coefficients and 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.*/

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
dequantize fewer coefficients and 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.*/

/*This table gives the square root of the fraction of the squared magnitude of
each DCT coefficient relative to the total, scaled by 2**16, for both INTRA
and INTER modes.
These values were measured after motion-compensated prediction, before
quantization, over a large set of test video (from QCIF to 1080p) encoded at
all possible rates.
The DC coefficient takes into account the DPCM prediction (using the
quantized values from neighboring blocks, as the encoder does, but still
before quantization of the coefficient in the current block).
The results differ significantly from the expected variance (e.g., using an
AR(1) model of the signal with rho=0.95, as is frequently done to compute
the coding gain of the DCT).
We use them to estimate an "average" quantizer for a given quantizer matrix,
as this is used to parameterize a number of the rate control decisions.
These values are themselves probably quantizer-matrix dependent, since the
shape of the matrix affects the noise distribution in the reference frames,
but they should at least give us _some_ amount of adaptivity to different
matrices, as opposed to hard-coding a table of average Q values for the
current set.
The main features they capture are that a) only a few of the quantizers in
the upper-left corner contribute anything significant at all (though INTER
mode is significantly flatter) and b) the DPCM prediction of the DC
coefficient gives a very minor improvement in the INTRA case and a quite
significant one in the INTER case (over the expected variance).*/

These are chosen to be as close to an exact inverse of the approximations
made in the iDCT as possible, while still using mostly 16-bit arithmetic.
We use some 16x16->32 signed MACs, but those still commonly execute in 1
cycle on a 16-bit DSP.
For example, s=(27146*t5+0x4000>>16)+t5+(t5!=0) is an exact inverse of
t5=(OC_C4S4*s>>16).
That is, applying the latter to the output of the former will recover t5
exactly (over the valid input range of t5, -23171...23169).
We increase the rounding bias to 0xB500 in this particular case so that
errors inverting the subsequent butterfly are not one-sided (e.g., the
mean error is very close to zero).
The (t5!=0) term could be replaced simply by 1, but we want to send 0 to 0.
The fDCT of an all-zeros block will still not be zero, because of the
biases we added at the very beginning of the process, but it will be close
