Drop Snow codec
Snow is a toy codec with no real-world use and horrible code.

-Snow Video Codec Specification Draft 20080110
-=============================================
-
-Introduction:
-=============
-This specification describes the Snow bitstream syntax and semantics as
-well as the formal Snow decoding process.
-
-The decoding process is described precisely and any compliant decoder
-MUST produce the exact same output for a spec-conformant Snow stream.
-For encoding, though, any process which generates a stream compliant to
-the syntactical and semantic requirements and which is decodable by
-the process described in this spec shall be considered a conformant
-Snow encoder.
-
-Definitions:
-============
-
-MUST the specific part must be done to conform to this standard
-SHOULD it is recommended to be done that way, but not strictly required
-
-ilog2(x) is the rounded down logarithm of x with basis 2
-ilog2(0) = 0
-
-Type definitions:
-=================
-
-b 1-bit range coded
-u unsigned scalar value range coded

-
-diag_mc
- flag to enable faster diagonal interpolation
- this SHOULD be 1 unless it turns out to be covered by a valid patent
-
-htaps
- number of half pel interpolation filter taps, MUST be even, >0 and <10
-
-hcoeff
- half pel interpolation filter coefficients, hcoeff[0] are the 2 middle
- coefficients [1] are the next outer ones and so on, resulting in a filter
- like: ...eff[2], hcoeff[1], hcoeff[0], hcoeff[0], hcoeff[1], hcoeff[2] ...
- the sign of the coefficients is not explicitly stored but alternates
- after each coeff and coeff[0] is positive, so ...,+,-,+,-,+,+,-,+,-,+,...
- hcoeff[0] is not explicitly stored but found by subtracting the sum
- of all stored coefficients with signs from 32
- hcoeff[0]= 32 - hcoeff[1] - hcoeff[2] - ...
- a good choice for hcoeff and htaps is
- htaps= 6
- hcoeff={40,-10,2}
- an alternative which requires more computations at both encoder and
- decoder side and may or may not be better is
- htaps= 8
- hcoeff={42,-14,6,-2}
-
-
-ref_frames
- minimum of the number of available reference frames and max_ref_frames
- for example the first frame after a key frame always has ref_frames=1
-
-spatial_decomposition_type

- 1 is a 5/3 symmetric compact integer wavelet

-Range Coding of integers:
--------------------------
-FIXME
-
-
-Neighboring Blocks:
-===================
-left and top are set to the respective blocks unless they are outside of
-the image in which case they are set to the Null block
-
-top-left is set to the top left block unless it is outside of the image in
-which case it is set to the left block
-
-if this block has no larger parent block or it is at the left side of its
-parent block and the top right block is not outside of the image then the
-top right block is used for top-right else the top-left block is used
-
-Null block
-y,cb,cr are 128
-level, ref, mx and my are 0
-
-
-Motion Vector Prediction:
-=========================
-1. the motion vectors of all the neighboring blocks are scaled to
-compensate for the difference of reference frames
-
-scaled_mv= (mv * (256 * (current_reference+1) / (mv.reference+1)) + 128)>>8
-
-2. the median of the scaled left, top and top-right vectors is used as
-motion vector prediction
-
-3. the used motion vector is the sum of the predictor and
- (mvx_diff, mvy_diff)*mv_scale
-
-
-Intra DC Predicton:
-======================
-the luma and chroma values of the left block are used as predictors
-
-the used luma and chroma is the sum of the predictor and y_diff, cb_diff, cr_diff
-to reverse this in the decoder apply the following:
-block[y][x].dc[0] = block[y][x-1].dc[0] + y_diff;
-block[y][x].dc[1] = block[y][x-1].dc[1] + cb_diff;
-block[y][x].dc[2] = block[y][x-1].dc[2] + cr_diff;
-block[*][-1].dc[*]= 128;
-
-
-Motion Compensation:
-====================
-
-Halfpel interpolation:
-----------------------
-halfpel interpolation is done by convolution with the halfpel filter stored
-in the header:
-
-horizontal halfpel samples are found by
-H1[y][x] = hcoeff[0]*(F[y][x ] + F[y][x+1])
- + hcoeff[1]*(F[y][x-1] + F[y][x+2])
- + hcoeff[2]*(F[y][x-2] + F[y][x+3])
- + ...
-h1[y][x] = (H1[y][x] + 32)>>6;
-
-vertical halfpel samples are found by
-H2[y][x] = hcoeff[0]*(F[y ][x] + F[y+1][x])
- + hcoeff[1]*(F[y-1][x] + F[y+2][x])
- + ...
-h2[y][x] = (H2[y][x] + 32)>>6;
-
-vertical+horizontal halfpel samples are found by
-H3[y][x] = hcoeff[0]*(H2[y][x ] + H2[y][x+1])
- + hcoeff[1]*(H2[y][x-1] + H2[y][x+2])
- + ...
-H3[y][x] = hcoeff[0]*(H1[y ][x] + H1[y+1][x])
- + hcoeff[1]*(H1[y+1][x] + H1[y+2][x])
- + ...

-
-Smaller pel interpolation:
---------------------------
-if diag_mc is set then points which lie on a line between 2 vertically,
-horiziontally or diagonally adjacent halfpel points shall be interpolated
-linearls with rounding to nearest and halfway values rounded up.
-points which lie on 2 diagonals at the same time should only use the one
-diagonal not containing the fullpel point

-
-the remaining points shall be bilinearly interpolated from the
-up to 4 surrounding halfpel and fullpel points, again rounding should be to
-nearest and halfway values rounded up
-
-compliant Snow decoders MUST support 1-1/8 pel luma and 1/2-1/16 pel chroma
-interpolation at least

-Overlapped block motion compensation:
--------------------------------------
-FIXME
-
-LL band prediction:
-===================
-Each sample in the LL0 subband is predicted by the median of the left, top and
-left+top-topleft samples, samples outside the subband shall be considered to
-be 0. To reverse this prediction in the decoder apply the following.
-for(y=0; y<height; y++){
- for(x=0; x<width; x++){
- sample[y][x] += median(sample[y-1][x],
- sample[y][x-1],
- sample[y-1][x]+sample[y][x-1]-sample[y-1][x-1]);
- }
-}
-sample[-1][*]=sample[*][-1]= 0;
-width,height here are the width and height of the LL0 subband not of the final
-video
-
-
-Dequantizaton:
-==============
-FIXME
-
-Wavelet Transform:
-==================
-
-Snow supports 2 wavelet transforms, the symmetric biorthogonal 5/3 integer
-transform and a integer approximation of the symmetric biorthogonal 9/7
-daubechies wavelet.
-
-2D IDWT (inverse discrete wavelet transform)
---------------------------------------------
-The 2D IDWT applies a 2D filter recursively, each time combining the
-4 lowest frequency subbands into a single subband until only 1 subband
-remains.
-The 2D filter is done by first applying a 1D filter in the vertical direction
-and then applying it in the horizontal one.
- --------------- --------------- --------------- ---------------
-|LL0|HL0| | | | | | | | | | | |
-|---+---| HL1 | | L0|H0 | HL1 | | LL1 | HL1 | | | |
-|LH0|HH0| | | | | | | | | | | |
-|-------+-------|->|-------+-------|->|-------+-------|->| L1 | H1 |->...
-| | | | | | | | | | | |
-| LH1 | HH1 | | LH1 | HH1 | | LH1 | HH1 | | | |
-| | | | | | | | | | | |
- --------------- --------------- --------------- ---------------

-
-1D Filter:
-----------
-1. interleave the samples of the low and high frequency subbands like
-s={L0, H0, L1, H1, L2, H2, L3, H3, ... }
-note, this can end with a L or a H, the number of elements shall be w
-s[-1] shall be considered equivalent to s[1 ]
-s[w ] shall be considered equivalent to s[w-2]
-
-2. perform the lifting steps in order as described below
-
-5/3 Integer filter:
-1. s[i] -= (s[i-1] + s[i+1] + 2)>>2; for all even i < w
-2. s[i] += (s[i-1] + s[i+1] )>>1; for all odd i < w

-Snow's 9/7 Integer filter:
-1. s[i] -= (3*(s[i-1] + s[i+1]) + 4)>>3; for all even i < w
-2. s[i] -= s[i-1] + s[i+1] ; for all odd i < w
-3. s[i] += ( s[i-1] + s[i+1] + 4*s[i] + 8)>>4; for all even i < w
-4. s[i] += (3*(s[i-1] + s[i+1]) )>>1; for all odd i < w

-optimization tips:
-following are exactly identical
-(3a)>>1 == a + (a>>1)
-(a + 4b + 8)>>4 == ((a>>2) + b + 2)>>2
-
-16bit implementation note:
-The IDWT can be implemented with 16bits, but this requires some care to
-prevent overflows, the following list, lists the minimum number of bits needed
-for some terms
-1. lifting step
-A= s[i-1] + s[i+1] 16bit
-3*A + 4 18bit
-A + (A>>1) + 2 17bit
-
-3. lifting step
-s[i-1] + s[i+1] 17bit
-
-4. lifiting step
-3*(s[i-1] + s[i+1]) 17bit
-
-
-TODO:
-=====
-Important:
-finetune initial contexts
-flip wavelet?
-try to use the wavelet transformed predicted image (motion compensated image) as context for coding the residual coefficients
-try the MV length as context for coding the residual coefficients
-use extradata for stuff which is in the keyframes now?
-the MV median predictor is patented IIRC
-implement per picture halfpel interpolation
-try different range coder state transition tables for different contexts
-
-Not Important:
-compare the 6 tap and 8 tap hpel filters (psnr/bitrate and subjective quality)
-spatial_scalability b vs u (!= 0 breaks syntax anyway so we can add a u later)
