2013-04-23Remove coeff from BLOCKJohn Koleszar
Lookup the data per-plane from the MACROBLOCK struct. Change-Id: I9253c4d3cf886aa9ab4aeab23a2156bfcf994ede
2013-04-23Convert coeff to per-plane MACROBLOCK dataJohn Koleszar
This commit moves the coeff storage from the MACROBLOCK struct to its per-plane part. The next commit will remove the coeff member from the BLOCK structure so that it is consistently accessed per-plane. Also refactors vp9_sb_block_error_c and vp9_sb_uv_block_error_c to be variable subsampling aware. Change-Id: I18c30f87f27c3a012119b6c1970d5fa499804455
2013-04-23Move src_diff to per-plane MACROBLOCK dataJohn Koleszar
First in a series of commits making certain MACROBLOCK members addressable per-plane. This commit also refactors the block subtraction functions vp9_subtract_b, vp9_subtract_sby_c, etc to be loops-over-planes and variable subsampling aware. Change-Id: I371d092b914ae0a495dfd852ea1a3d2467be6ec3

2013-04-22End of orientation zero group experimentDeb Mukherjee
Adds an experiment that codes an end-of-orientation symbol for every eligible zero encountered in scan order. This cleans out various other sub-experiments that were part of the origiinal patch, which will be later included if found useful. Results are slightly positive on all sets (0.1 - 0.2% range).

2013-04-19Simplification of MVref search.Paul Wilkins
As we are no longer able to sort the candidate mvrefs in both encoder and decode and given that the cost of explicit signalling has proved prohibitive, it no longer makes sense to find more than 2 candidates. This patch: Modifies and simplifies add_candidate_mv() Removes the forced addition of a 0 vector in the MAX_MV_REF_CANDIDATES-1 position (in preparation to reducing MAX_MV_REF_CANDIDATES to 2). Re-orders the addition of candidates slightly. This actually gives small gains (circa 0.2% on std-hd) A subsequent patch will remove NEW_MVREF experiment, reduce MAX_MV_REF_CANDIDATES to 2 and remove distance weights as these are implicit now in the order.

2013-04-19Merge "Adjustments to key frame sizing." into experimentalPaul Wilkins
2013-04-19Adjustments to key frame sizing.Paul Wilkins
Adjustments take heavier account of the frame near a kf in deciding boost and limit the total number that can contribute. Also adjusted the minq calculations such that in most cases we generate a smaller key frame. Modified the code that accounts for how static the sequence is and added some adjustment based on image size. This is still very crude but smaller images tend to behave better with a larger delta between KF Q and other frames than larger image formats. Changes give sizable gains in overall PSNR on all the test sets but the biggest gains (~3%) were on the std-hd set. The gains were smaller for SSIM but still significant. Average PSNR results are mixed because this metric can very easily be altered by having a very good / lossless coding of one or two frames. Some of the YT and YT-HD clips in particular have blank lead ins and allowing lossless coding of these appears to make a big difference to average PSNR but it reality does not help much at all.

* changes: Removing rounding from UV MV calculation make buid_inter_predictors block size agnostic (luma)
2013-04-18Removing rounding from UV MV calculationJohn Koleszar
Consider the previous behavior for the MV 1 3/8 (11/8 pel). In the existing code, the fractional part of the MV is considered separately, and rounded is applied, giving a result of 6/8. Rounding is not required in this case, as we're increasing the precision from a q3 to a q4, and the correct value 11/16 can be represented exactly. Slight gain observed (+.033 average on derf) Change-Id: I320e160e8b12f1dd66aa0ce7966b5088870fe9f8
2013-04-18make buid_inter_predictors block size agnostic (luma)John Koleszar
This commit converts the luma versions of vp9_build_inter_predictors_sb to use a common function. Update the convolution functions to support block sizes larger than 16x16, and add a foreach_predicted_block walker. Next step will be to calculate the UV motion vector and implement SBUV, then fold in vp9_build_inter16x16_predictors_mb and SPLITMV. At the 16x16, 32x32, and 64x64 levels implemented in this commit, each plane is predicted with only a single call to vp9_build_inter_predictor. This is not yet called for SPLITMV. If the notion of SPLITMV/I8X8/I4X4 goes away, then the prediction block walker can go away, since we'll always predict the whole bsize in a single step. Implemented using a block walker at this stage for SPLITMV, as a 4x4 "prediction block size" within the BLOCK_SIZE_MB16X16 macroblock. It would also support other rectangular sizes too, if the blocks smaller than 16x16 remain implemented as a SPLITMV-like thing. Just using 4x4 for now. There's also a potential to combine with the foreach_transformed_block walker if the logic for calculating the size of the subsampled transform is made more straightforward, perhaps as a consequence of supporing smaller macroblocks than 16x16. Will watch what happens there. Change-Id: Iddd9973398542216601b630c628b9b7fdee33fe2
