2018-10-05Changes to facilitate accurate sub-pel motion searchYunqing Wang
This patch included changes to facilitate accurate sub-pel motion search. More patch will follow to turn on accurate sub-pel motion search. Change-Id: I224c28c338353fe5c7609372162f79885c54248f
2018-09-21Improve subpel MV search for speed 1Hui Su
Do one more subpel MV search each round. This improves coding efficiency slightly: lowres 0.12% midres 0.11% hdres 0.13% Also renames the control flag for subpel MV search quality. Encoding speed loss is less than 1%. This only affects speed 1. Change-Id: I3aecd25342f2dcacea6c143db494f7db6282cb92
2017-04-03Fix for out of range motion vector bug in sub-pel motion estimationRanjit Kumar Tulabandu
BUG=webm:1397 (yunqingwang) To verify that this patch wouldn't cause much performance change, the Borg tests were run. Here was the result: avg_psnr overall_psnr ssim hdres: -0.002 0.006 0.013 midres: 0 0 0 lowres: 0 0 0 Change-Id: Iae395ae7b741e0513cf5bab9dcace110b792a67d

instead of calling vp9_hex_search() directly. this will allow the function to be made private Change-Id: I2f9d4779763aa5b24eda4eb01c78954e061e45ac
2015-08-26vpx_dsp_common: add VPX prefix to MIN/MAXJames Zern

2015-05-06Move shared SAD code to vpx_dspJohann
Create a new component, vpx_dsp, for code that can be shared between codecs. Move the SAD code into the component. This reduces the size of vpxenc/dec by 36k on x86_64 builds. Change-Id: I73f837ddaecac6b350bf757af0cfe19c4ab9327a

2015-04-21Revert "Remove mi_grid_* structures."Scott LaVarnway
(see I3a05cf1610679fed26e0b2eadd315a9ae91afdd6) For the test clip used, the decoder performance improved by ~2%. This is also an intermediate step towards adding back the mode_info streams. Change-Id: Idddc4a3f46e4180fbebddc156c4bbf177d5c2e0d
2015-03-04Make encoder buffer allocation dynamicAdrian Grange
Frame buffers are now allocated dynamically on-demand. Entries in the reference frame map, cm->ref_frame_map, may now be set to -1 (INVALID_IDX) to indicate that there is not a valid reference buffer in that "slot". All slots in the reference frame map are now initialized to the empty state (-1) and each buffer is initialized to have a reference count of 0. Change-Id: Id1afe98de98db4ae8b2dfefed7889c3b28c68582
2014-11-24vp9_ethread: modify VP9_COMP structureYunqing Wang
This patch modified struct VP9_COMP. Created a struct ThreadData to include data that need to be copied for each thread. In multiple thread case, one thread processes one tile. all threads share one copy of VP9_COMP, (refer to VP9_COMP *cpi in the code) but each thread has its own copy of ThreadData, (refer to ThreadData *td in the code). Therefore, within the scope of encode_tiles(), both cpi and td need to be passed as function parameters. In single thread case, the FRAME_COUNTS pointer in ThreadData points to "counts" in VP9_COMMON. Change-Id: Ib37908b2d8e2c0f4f9c18f38017df5ce60e8b13e
2014-11-20Revert "vp9_ethread: include a pointer to mb in VP9_COMP"Yunqing Wang

2014-11-14vp9_ethread: include a pointer to mb in VP9_COMPYunqing Wang
Modified VP9_COMP struct to include MACROBLOCK *mb. This change makes it feasible in multi-thread case to allocate a mb for each thread. Change-Id: I624d6d1aa9c132362200753e5d90b581b1738d6e
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.

2014-09-19Remove mi_grid_* structures.hkuang
mi_grid_* are arrays of pointer to pointer. They save the pointers that point to the MIs in cm->mi. But they are unnecessary and complicated. The original goal was to remove MODE_INFO_t copy. But with an extra MODE_INFO_t pointer inside MODE_INFO_t, same goal could be achieved. This commit totally removes the mi_grid_* structures. But there are still many dummy MODE_INFO_t inside cm->mi which are a waste of memory. Next commit will do on-demand MODE_INFO_t allocation in order to save these memories.

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

2014-07-07Cleanup motion search speed features.Alex Converse

2014-06-02Remove Wextra warnings from vp9_sad.cDeb Mukherjee

2014-05-14Remove Wextra warnings from vp9_sad.cDeb Mukherjee
As a side-effect, the max_sad check is removed from the C-implementation of VP8, for consistency with VP9, and to ensure that the SAD tests common to VP8/VP9 pass. That will make the VP8 C implementation of sad a little slower but given that is rarely used in practice, the impact will be minimal. Change-Id: I7f43089fdea047fbf1862e40c21e4715c30f07ca
