This function sets the motion search range limit. Rename it to be more informative. Change-Id: I2e8e01073dcb99c9bea9c9acd0a61d672d615444
2013-11-18Constrain encoder motion search rangeJingning Han
Explicitly constrain the upper limit of motion search range (in the unit of full pixel) to be [-1023, +1023]. It is intended to control the effective motion search range for 4K sequences. Change-Id: I645539c70885eec0f155781f439d97d333336e88
2013-10-17Adding allow_hp as an argument to mv search functions.Dmitry Kovalev
Making this change in order to move allow_high_precision_mv field from MACROBLOCKD structure to VP9_COMMON (because it is a frame level flag). Change-Id: I1d006ba36d938e0caf4d40fa051e2e38df9c1108

2013-09-24Limit mv search range for first pass and mbgraphYaowu Xu
Both first pass and mbgraph search use block size 16x16 for motion estimation. This commit put a limit of motion vector range. The effective range allows the entire 16x16 with required subpel interpolation input to be completely outside image border, but not any further away from image border.

2013-08-08Adds a new subpel motion functionDeb Mukherjee
Adds a new subpel motion estimation function that uses a 2-level tree-structured decision tree to eliminate redundant computations. It searches fewer points than iterative search (which can search the same point multiple times) but has the same quality roughly. This is made the default setting at speeds 0 and 1, while at speed 2 and above only a 1-level search is used. Also includes various cleanups for consistency and redundancy removal. Results: derf: +0.012% psnr stdhd: +0.09% psnr Speedup of about 2-3% Change-Id: Iedde4866f5475586dea0f0ba4cb7428fba24eee9
2013-08-06Clean ups of the subpel search functionsDeb Mukherjee
Removes some unused code and speed features, and organizes the interfaces for fractional mv step functions for use in new speed features to come. In the process a new speed feature - number of iterations per step during the subpel search - is exposed. No change when this parameter is set as the original value of 3. Results: subpel_iters_per_step = 3: baseline subpel_iters_per_step = 2: psnr -0.067%, 1% speedup subpel_iters_per_step = 1: psnr -0.331%, 3-4% speedup Change-Id: I2eba8a21f6461be8caf56af04a5337257a5693a8
2013-08-06Flexible support for various pattern searchesDeb Mukherjee
Adds a few pattern searches to achieve various tradeoffs between motion estimation complexity and performance. The search framework is unified across these searches so that a common pattern search function is used for all. Besides it will be easier to experiment with various patterns or combinations thereof at different scales in the future. The new pattern search is multi-scale and is capable of using different patterns at different scales. The new hex search uses 8 points at the smallest scale and 6 points at other scales. Two other pattern searches - big-diamond and square are also added. Big diamond uses 4 points at the smallest scale and 8 points in diamond shape at the larger scales. Square is very similar conceptually to the default n-step search but is somewhat faster since it keeps only one survivor across all scales. Psnr/speed-up results on derf300: hex: -1.6% psnr%, 6-8% speed-up big-diamond: -0.96% psnr, 4-5% speedup square: -0.93% psnr, 4-5% speedup Change-Id: I02a7ef5193f762601e0994e2c99399a3535a43d2

2013-06-26Change meaning of cpi->sf.first_step and rename.Paul Wilkins
Renamed cpi->sf.first_step to cpi->sf.reduce_first_step_size and changed its meaning such that it is a delta applied to reduce the default first step size (>> x) in the motion search rather than an absolute value. The default first step size is already changed according to the image dimensions (smaller for smaller images). cpi->sf.reduce_first_step_size now applies a further correction from the default.

2013-05-16New inter mode context.Paul Wilkins
This patch creates a new inter mode contest that avoids a dependence on the reconstructed motion vectors from neighboring blocks. This was a change requested by a hardware vendor to improve decode performance. As part of this change I have also made some modifications to stats output code (under a flag) to allow accumulation of inter mode context flags over multiple clips Some further changes will be required to accommodate the deprecation of the split mv mode over the next few days. Performance as stands is around -0.25% on derf and std-hd but up on the YT and YT-HD sets. With further tuning or some adjustment to the context criteria it should be possible to make this change broadly neutral. Change-Id: Ia15cb4470969b9e87332a59c546ae0bd40676f6c
2013-05-10Add joint motion search in comp_inter_inter mode(experiment)Yunqing Wang
In current code, motion vectors got from single prediction mode are used in compound prediction mode directly. These motion vectors may not give accurate prediction since they are searched independently. In this patch, we took Pascal's suggestion, and did joint motion search in compound prediction mode to find better motion vectors in this situation. Test results: Overall PSNR: 0.570%(derf), 0.918%(stdhd); SSIM: 0.572%(derf), 1.009%(stdhd); The encoder is a little slower. This can be improved since some c code is used in motion search.

2013-04-26Removed bmi from blockdScott LaVarnway
This originally was "Removed update_blockd_bmi()". Now, this patch removed bmi from blockd and uses the bmi found in mode_info_context. Eliminates unnecessary bmi copies between blockd and mode_info_context. Change-Id: I287a4972974bb363f49e528daa9b2a2293f4bc76

2013-03-13Support +/-2048 motion vector codingJingning Han
Enable entropy coding of motion vectors up to +/-2048. Also extend the motion search range accordingly. Change-Id: Iac2bb015e8934521cef83a19edbe967d9f097436
2013-03-08Extend diff MV limit from +/-256 to +/-1024Jingning Han
Increase the motion search range by 4x. Change MV_CLASS tree of the entropy coding to allow two additional mv classes to cover the extended motion vector limit. The codec determines the effective motion search range conditioned on the actual frame dimension. It provides coding gains: stdhd 0.39% yt 0.56% hd 0.47% Major coding performance gains are packed in several sequences with intense motion activities, e.g., ped_1080p gains 7% at high bit-rates, and on average 3%. TODO: Need to further tune the rate control and motion search units. Change-Id: Ib842540a6796fbee5a797809433ef6a477c6d78d
