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
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
This reverts commit 6906d218ddd1af97228a797f4558e402231d94f1. Another way will be used to handle mb struct. Change-Id: Ic1111a46b2b1ee00f8f9e3fcd4cf3eb6030b2dc4
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
2014-09-19Remove 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.

2014-07-02Adapt strength of AQ2.Paul Wilkins
Adapt the use of segmentation in AQ mode 2 based on the ambient kf/arf/gf Q. Disable segmentation where the rate per SB is very low and overheads are likely to outweigh the benefits. This patch reduces the -ve average metrics impact of AQ mode 2 while allowing stronger 3 segment AQ in some cases. Average improvement ~0.5-1.0%. Change-Id: I5892dfcc7507c5cc6444531cc7fe17554cf8d0c7

2013-10-28vp9: add TileInfoJames Zern
replaces use of cur_tile_mi_(row|col)_(start|end) by VP9_COMMON, making it less stateful and more reusable for parallel tile decoding Change-Id: I1df09382b4567a0e5f4434825d47c79afe2399be
2013-10-16Get rid of "this_mi", use "mi_8x8[0]" everywhere insteadGuillaume Martres
The only case where they were intentionally pointing to different structures was in mbgraph, and this didn't have the expected behavior because both of these pointers are used interchangeably through the code Change-Id: I979251782f90885fe962305bcc845bc05907f80c
2013-10-15Updated encoder to handle intra-only framesAlexander Voronov
Updated the encoder to handle frames that are coded intra-only. Intra-only frames must be non-showable, that is, the "show frame" flag must be set to 0 in the frame header. Tested by forcing the ARF frames to be coded intra- only. Note: The rate control code will need to be modified to account for intra-only frames better than they are currently handled.

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
2013-09-09Revert "New mode_info_context storage"James Zern

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).

2013-07-23Renaming of segment constants.Paul Wilkins
Renamed: MAX_MB_SEGMENTS to MAX_SEGMENTS MB_SEG_TREE_PROBS to SEG_TREE_PROBS The minimum unit for segmentation in the segment map is now 8x8 so it is misleading to use MB_ as macro-block traditionally refers to a 16x16 region. Change-Id: I0b55a6f0426bb46dd13435fcfa5bae0a30a7fa22

Making implementation of vp9_set_pred_flag_{seg_id, mbskip} consistent with vp9_get_segment_id without using confusing sub(a, b) macro. Passing mi_row and mi_col to functions explicitly instead of replying on mb_to_right_edge and mb_to_bottom_edge. Change-Id: I54c1087dd2ba9036f8ba7eb165b073e807d00435
