2013-08-09Moving loopfilter struct to VP9_COMMON.Dmitry Kovalev
Loop filter configuration doesn't belong to macroblock, so moving it from MACROBLOCKD to VP9_COMMON. Also moving the declaration of loopfilter struct from vp9_blockd.h to vp9_loopfilter.h. Change-Id: I4b3e34be9623b47cda35f9b1f9951f8c5b1d5d28

2013-08-07Adding ss_size_lookup table.Dmitry Kovalev
Removing the old one bsize_from_dim_lookup. Now we have a way to determine block size for plane using its subsampling values (ss_size_lookup). And then we can find the number of pixels in the block (num_pels_log2_lookup). Change-Id: I6fc981da2ae093de81741d3d78eaefed11015db9
2013-08-06Using only one scale function in scale_factors struct.Dmitry Kovalev
Functions scale_mv_q4 and scale_mv_q3_to_q4 were almost identical except q3->q4 conversion in scale_mv_q3_to_q4. Now q3->q4 conversion happens directly in vp9_build_inter_predictor. Also adding useful constants: SUBPEL_BITS and SUBPEL_MASK. Change-Id: Ia0a6ad2ac07c45fdf95a5139ece6286c035e9639
2013-08-05Changing the order switchable filter enum constants.Dmitry Kovalev
This changeset allows to remove vp9_switchable_interp and vp9_switchable_interp_map arrays and make code much clear. Actually we still have to use these mapping but only inside read_interp_filter_type and write_interp_filter_type functions. Change-Id: I4026c6f8c4acefba6c81421b7bacbaa52cc45f50

2013-07-22Optimize operation flow in sub8x8 rd loopJingning Han
Stack the rate-distortion statistics in the sub8x8 rd loop. This allows the encoder to skip the forward transform, quantization, and coeff cost estimation, in the sub8x8 rd optimization search, if the motion vector(s) are of integer pixel value, and have been tested in the previous prediction filter type rd loops of the same block. This gives about 2% speed-up for bus_cif at 2000 kpbs, for speed 0. Its efficacy depends how frequently the motion search will select an integer motion vector.

2013-07-18Merge scale_factors and scale_factors_uv.Ronald S. Bultje
This prevents a duplicate memcpy of a 128-byte struct every time set_scale_factors() is called (which is a lot), thus leading to a decrease from 3.7 MB to 1.85 MB of struct copying per 64x64 block RD/partition loop. Overall, this decreases encoding time of the first 50 frames of bus @ 1500kbps (speed 0) from 1min5.9 to 1min4.9, i.e. about a 1.5% overall speedup. We can likely get more gains by removing the copy of the other struct (and replacing it with an indexing) as well. Change-Id: I3dceb7e79f71e6fe911b11cc994cf89a869dde7a

2013-07-12Some minor cleanups for efficiencyDeb Mukherjee
Implements some of the helper functions more efficiently with lookups rathers than branches. Modeling function is consolidated to reduce some computations. Also merged the two enums BLOCK_SIZE_TYPES and BlockSize into one because there is no need to keep them separate (even though the semantics are a little different). No bitstream or output change. About 0.5% speedup Change-Id: I7d71a66e8031ddb340744dc493f22976052b8f9f

2013-07-10Prunes out full-rd computation based on modeled rdDeb Mukherjee
Adds a speed feature to eliminate full-rd computation if the modeled rd or rd based on a different parameter in the same mode is already a lot larger than the best rd yet. Specifically, only search the sharp and smooth filters if the modeled rd cost based on the regular filter is within a certain factor of the best rd cost so far. Also, skip full-rd computation of non splitmv inter modes if the modeled rd cost based on pred error is within the same factor of the best rd cost so far. Also adds some enhancements in the rd search for splitmv mode to speed things up by early breakouts. Negligible impact on performance. Resuts on derfraw300: psnr: -0.013% with the splitmv enhancements, -0.24% with the rd breakout feature on. speedup: 6% with splitmv enhancements, 20% with also residual breakout (tested on football sequence at 600 Kbps) Change-Id: I37abc308ea9f110c1679ce649b6a7e73ab1ad5fc

Replace case statement with lookup. Small speed gain at low speed settings but at speed 2+ where the number of motion searches etc. falls the impact rises to ~3-4%. Change-Id: Idff639b7b302ee65e042b7bf836943ac0a06fad8 Change-Id: I5940719a4a161f8c26ac9a6753f1678494cec644

2013-07-02Tx size selection enhancementsDeb Mukherjee
(1) Refines the modeling function and uses that to add some speed features. Specifically, intead of using a flag use_largest_txfm as a speed feature, an enum tx_size_search_method is used, of which two of the types are USE_FULL_RD and USE_LARGESTALL. Two other new types are added: USE_LARGESTINTRA (use largest only for intra) USE_LARGESTINTRA_MODELINTER (use largest for intra, and model for inter) (2) Another change is that the framework for deciding transform type is simplified to use a heuristic count based method rather than an rd based method using txfm_cache. In practice the new method is found to work just as well - with derf only -0.01 down. The new method is more compatible with the new framework where certain rd costs are based on full rd and certain others are based on modeled rd or are not computed. In this patch the existing rd based method is still kept for use in the USE_FULL_RD mode. In the other modes, the count based method is used. However the recommendation is to remove it eventually since the benefit is limited, and will remove a lot of complications in the code (3) Finally a bug is fixed with the existing use_largest_txfm speed feature that causes mismatches when the lossless mode and 4x4 WH transform is forced. Results on derf: USE_FULL_RD: +0.03% (due to change in the tables), 0% encode time reduction USE_LARGESTINTRA: -0.21%, 15% encode time reduction (this one is a pretty good compromise) USE_LARGESTINTRA_MODELINTER: -0.98%, 22% encode time reduction (currently the benefit of modeling is limited for txfm size selection, but keeping this enum as a placeholder) . USE_LARGESTALL: -1.05%, 27% encode-time reduction (same as existing use_largest_txfm speed feature). Change-Id: I4d60a5f9ce78fbc90cddf2f97ed91d8bc0d4f936
