2014-10-15Some updates for Speed 6/VAR_BASED_PARTITION.Marco
Reduce the intra_cost_penalty for non-rd mode, and some updates to VAR_BASED_PARTITION. Visual tests show some improvement at Speed 6, for RTC clips. Change-Id: If9090daf7aed14906a32d931a538ab544bbca606

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.

2014-10-07experimental : partition using 1/8 x 1/8 imageJim Bankoski
The concept: There's too much noise in source pixels for variance and at low bitrate the reconstructed looks nothing like the source so we have problems getting good partitionings with either. This skirts the issue by using a box blur scaled down version for variance calculations. To compare against source_var_ moved keyframe to be rd based like source_var.

2014-10-07Take out repeated block width/height lookup functionsJingning Han
The functions b_width_log2 and b_height_log2 only do direct table fetch. This commit unifies such use cases by using the table directly and removes these functions. Change-Id: I3103fc6ba959c1182886a2799d21b8b77c8a7b6b

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

2014-07-15VP9 Denoiser denoises after mode/bsize searchTim Kopp
In vp8, statistics are collected about the different modes as they are searched. This process is more complicated due to the variable block size. Fields were added to the PICM_MODE_CONTEXT struct to hold this information for each point in the search. The information is then taken from the appropriate part of the tree during denoising.

2014-07-11Fix chrome valgrind warning due to the use of mismatched bsizeJingning Han
This commit fixes a mismatched use case of block size in non-RD intra prediction check. The residual SSE and variance should be calculated per transform block size, instead of operating block size, which caused chrome valgrind warning on conditional jump based on uninitialized value (webm issue 823). This commit resolves this issue. Change-Id: I595c06599c7e0fd0e4a08736519ba68fc14bc79a

As in VP8. Currently, this parameter is set with the VP8E_SET_NOISE_SENSITIVITY flag. The flag was not renamed so that we don't break the interface for webrtc. This should probably be changed at some point in the future. Change-Id: Ic73fcb0dde9d1d019e9d042050b617333ac65472
