2012-12-10A bug fix related to switchable filtersDeb Mukherjee
The switchable count update was mistakenly inside a macro. Change-Id: Iec04c52ad57034b88312dbaf05eee1f47ce265b3
2012-12-10Further changes to mv reference code.Paul Wilkins
Some further changes and refactoring of mv reference code and selection of center point for searches. Mainly relates to not passing so many different local copies of things around. Some place holder comments. Change-Id: I309f10ffe9a9cde7663e7eae19eb594371c8d055

2012-12-07Clean up 4x4 coefficient decoding code.Ronald S. Bultje
Don't use vp9_decode_coefs_4x4() for 2nd order DC or luma blocks. The code introduces some overhead which is unnecessary for these cases. Also, remove variable declarations that are only used once, remove magic offsets into the coefficient buffer (use xd->block[i].qcoeff instead of xd->qcoeff + magic_offset), and fix a few Google Style Guide violations.

2012-12-07Introduce vp9_coeff_probs/counts/stats/accum types.Ronald S. Bultje
Use these, instead of the 4/5-dimensional arrays, to hold statistics, counts, accumulations and probabilities for coefficient tokens. This commit also re-allows ENTROPY_STATS to compile. Change-Id: If441ffac936f52a3af91d8f2922ea8a0ceabdaa5

2012-12-0732x32 transform for superblocks.Ronald S. Bultje
This adds Debargha's DCT/DWT hybrid and a regular 32x32 DCT, and adds code all over the place to wrap that in the bitstream/encoder/decoder/RD. Some implementation notes (these probably need careful review): - token range is extended by 1 bit, since the value range out of this transform is [-16384,16383]. - the coefficients coming out of the FDCT are manually scaled back by 1 bit, or else they won't fit in int16_t (they are 17 bits). Because of this, the RD error scoring does not right-shift the MSE score by two (unlike for 4x4/8x8/16x16). - to compensate for this loss in precision, the quantizer is halved also. This is currently a little hacky. - FDCT and IDCT is double-only right now. Needs a fixed-point impl. - There are no default probabilities for the 32x32 transform yet; I'm simply using the 16x16 luma ones. A future commit will add newly generated probabilities for all transforms. - No ADST version. I don't think we'll add one for this level; if an ADST is desired, transform-size selection can scale back to 16x16 or lower, and use an ADST at that level. Additional notes specific to Debargha's DWT/DCT hybrid: - coefficient scale is different for the top/left 16x16 (DCT-over-DWT) block than for the rest (DWT pixel differences) of the block. Therefore, RD error scoring isn't easily scalable between coefficient and pixel domain. Thus, unfortunately, we need to compute the RD distortion in the pixel domain until we figure out how to scale these appropriately. Change-Id: I00386f20f35d7fabb19aba94c8162f8aee64ef2b

2012-12-05Begin to refactor vpx_scale usage in VP9Johann
Only declare the functions in vpx_scale RTCD and include the relevant header. Remove unused files and functions in vpx_scale to avoid wasting time renaming. vpx_scale/win32/scaleopt.c contains functions which have not been called in a long time but are potentially optimized. The 'vp8' functions have not been renamed yet. That is for after the cleanup. Change-Id: I2c325a101d60fa9d27e7dfcd5b52a864b4a1e09c

2012-12-05Change to MV reference search.Paul Wilkins
This patch reduces the cpu cost of the MV ref search by only allowing insert for candidates that would be in the current top 4. This could alter the outcome and slightly favors near candidates which are tested first but also limits the worst case loop count to 4 and means in many cases it will drop out and not happen.
