2014-01-21Enforce effective motion vector search rangeJingning Han
This commit explicitly enforces the effective motion vector range in the motion search stage. The range needs to be the intersection of UMV border, effective absolute motion vector value range, and the target search area. Change-Id: I1cf7c563e02b1086040dad6c1f4f6be1538635a6

2013-12-06Full range motion search for regular block sizesJingning Han
Add a full range motion search for regular block sizes. This runs exhaustive search within the given reference area. This commit further optimizes the search process by combining 4 points test into one pipeline, which gives 30% speed-up as compared to run each individual point at a time. This full range search serves as a best possible motion search reference. When replacing the diamond search with full range search, the speed 0 runtime of bus CIF at 2000 kbps goes from 153872ms to 623051ms. The compression performance compared to speed 0 setting gains 0.585% for derf set. Change-Id: Ieef1225216b0b86b4ac4872fa7fb9e18bf2eabb3
2013-11-18Constrain encoder motion search rangeJingning Han

2013-09-11New mode_info_context storage -- undo revertScott LaVarnway
mode_info_context was stored as a grid of MODE_INFO structs. The grid now constists of pointers to MODE_INFO structs. The MODE_INFO structs are now stored as a stream (decoder only), eliminating unnecessary copies and is a little more cache friendly. Change-Id: I031d376284c6eb98a38ad5595b797f048a6cfc0d

2013-09-06New mode_info_context storageScott LaVarnway
mode_info_context was stored as a grid of MODE_INFO structs. The grid now constists of a pointer to a MODE_INFO struct and a "in the image" flag. The MODE_INFO structs are now stored as a stream, eliminating unnecessary copies and is a little more cache friendly. For the test clips used, the decoder performance improved by ~4.3% (1080p) and ~9.7% (720p). Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p) and 5.9% (720p).

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
