2017-04-06VP9 motion vector unit testYunqing Wang
To prevent the motion vector out of range bug, added a motion vector unit test in VP9. In the 4k video encoding, always forced to use extreme motion vectors and also encouraged to use INTER modes. In the decoding, checked if the motion vector was valid, and also checked the encoder/decoder mismatch. The tests showed that this unit test could reveal the issue we saw before.

2015-11-11Add AVX vectorized vp9_diamond_search_sadGeza Lore
This function now has an AVX intrinsics version which is about 80% faster compared to the C implementation. This provides a 2-4% total speed-up for encode, depending on encoding parameters. The function utilizes 3 properties of the cost function lookup table, constructed in 'cal_nmvjointsadcost' and 'cal_nmvsadcosts'. For the joint cost: - mvjointsadcost[1] == mvjointsadcost[2] == mvjointsadcost[3] For the component costs: - For all i: mvsadcost[0][i] == mvsadcost[1][i] (equal per component cost) - For all i: mvsadcost[0][i] == mvsadcost[0][-i] (Cost function is even) These must hold, otherwise the AVX version of the function cannot be used.

2014-10-08Subpel search cleanups and enhancementsDeb Mukherjee
- Some fixes to surface fit. - Returns variance function as cost rather than sad in the pattern search and diamond search functions. Only vp9_pattern_search_sad function used in bigdia search uses sad as integer 1-away costs. - Deploys SUBPEL_TREE_PRUNED_MORE for speed 4+. Results: derf [Speed 3]: About +0.036% in coding efficiency without any discernible speed loss. derf [Speed 4]: About 2-3% faster at -0.199% loss in coding efficiency. derf [Speed 5]: About 3-4% faster at -0.149% loss in coding efficiency.

2014-09-29Adds two new subpel search methodsDeb Mukherjee
One is a more aggressive version of the pruned subpel tree search where only a single halfpel candidate is searched. The search candidate is based on a surface fit result. The other is a method to obtain the subpel position at one shot based on the same surface fit. The methods have not been deployed in any speed setting yet.

2014-09-23Pruned subpel search for speed 3.Deb Mukherjee
Adds code to return an integer cost list for NSTEP search. Then uses it for pruned subpel search in speed 3. derf: -0.06% Speed on mobcal 720p increaes from 10.28 fps to 10.65 fps. [Subject to further testing]. Change-Id: Ib591382d25b2c11bcaba9d3a27a93a9d1ab27a96
2014-08-28Updates vp9_pattern search to return integer sadsDeb Mukherjee
Updates the vp9_pattern_search function to return integer one-away neighbors' sad values, for subsequent use in speeding up the sub-pel search. Also, removes code for the do_refine option which is not being used currently. Updates the integer and subpel functions to pass in a 5-element sad list for output or input. A new pruned sub-pel search algorithm is implemented that uses the sad returned from the integer pel search. But it is not deployed yet. Change-Id: Ifa9f5ad024b5b660570366d2bd900343e1891520

2014-03-03Refactoring motion search libsDeb Mukherjee
The core motion estimation fucntions all return sad now consistently. The only exception is vp9_full_pixel_diamond(), however the core diamond and refining search routines called from vp9_full_pixel_diamond() also return SAD. If variance of pred error + mv cost is desired it must be calculated explicitly outside these functions. For very fast encoding, hopefully this will eliminate some redundant computations. Also suggests reimplementing FAST_HEX with the vp9_pattern_search framework. It is not exactly the same as the existing FAST_HEX, but performance is slightly better and speed is very similar. Enables removing a lot of duplicate code. Change-Id: I152736393438c25bdf7e96b37cbb8ce330f4f94a
