2013-12-04Merge "Cleaning up vp9_entropy.h file."Dmitry Kovalev
2013-12-03Moving eob array to the encoder.Dmitry Kovalev
In the decoder we don't need to save eobs, we can pass eob as an argument. That's why removing eob arrays from VP9Decompressor and TileWorkerData, and moving eob pointer from macroblockd_plane to macroblock_plane. Change-Id: I8eb919acc837acfb3abdd8319af63d1bbca8217a
2013-12-03Cleaning up vp9_entropy.h file.Dmitry Kovalev

2013-11-26Removing qcoeff buffers from the decoder.Dmitry Kovalev
We only need qcoeff buffers in the encoder. Reducing TileWorkerData struct and VP9Decompressor struct sizes by 24K. Change-Id: Id148868461f7ffa3d3dd634b371503ae9c57e207

2013-11-13Simplifies band-getting with a static arrayDeb Mukherjee
Simplifies the code by implementing band mapping with static arrays. A lot of the code complexity introduced in a previous patch disappears. Change-Id: Ia3fac36e594fb5ad2d55ae141c58bba4c55c2d28
2013-11-12Adding const to tree pointer inside vp9_extra_bit struct.Dmitry Kovalev
Change-Id: I60e02fa3de930ff1f969687ab5af93dee40d86ad
2013-11-12Removes conditional statements from band gettingDeb Mukherjee
Implements scan order to band map with arrays in both the encoder and decoder to remove conditional statements. Encoding seems to be about 1% faster at speed 0, tested on football. Decoding seems to be about 0.5-1% faster on a set of 25 videos. Change-Id: Idb233ca0b9e0efd790e30880642e8717e1c5c8dd

* changes: Use a separate MODE_INFO stream for each tile column Get rid of "this_mi", use "mi_8x8[0]" everywhere instead Make the static_segmentation feature work again
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
2013-10-16Adding get_band_translate() function.Dmitry Kovalev
Moving code that gets band_translate array from get_scan_and_band() function to get_band_translate() function. Renaming get_scan_and_band() to get_scan(). Change-Id: I43047c205a1ca2a6e24be44db39dc04b7a385008

Extracting get_scan_and_band function from get_entropy_context to remove duplicated code. Change-Id: I5da1f5a60263017e887da68bc834317b5f084cb2
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
This reverts commit dae17734ece414091ba1184f7becd0aa6c0004f1 Encode crashes, leaks and increases integer overflow errors. Change-Id: I595aa2649bb8d0b6552ff91652837a74c103fda2
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).

2013-08-21Removing a lot of duplicated code.Dmitry Kovalev
Adding set_contexts contexts function and call it instead of set_contexts_on_border. Calling txfrm_block_to_raster_xy to get aoff and loff. Change-Id: I41897e344afd2cae1f923f4fdbe63daccf6fe80e
2013-08-19Passing plane_bsize to foreach_transformed_block_visitor.Dmitry Kovalev
Updating all foreach_transformed_block_visitor functions to work with plane block size instead of general block. Removing a lot of duplicated code. Change-Id: I6a9069e27528c611f5a648e1da0c5a5fd17f1bb4

2013-08-15Merge "Moving segmentation struct from MACROBLOCKD to VP9_COMMON."Dmitry Kovalev
2013-08-15Refactor rd loop for chroma componentsJingning Han
This commit makes the rate-distortion optimization search of chroma components consistent across all block sizes. It removes redundant codes. Change-Id: I7e76f54d045e8efdd41d84a164c71f55b484471b
2013-08-15Moving segmentation struct from MACROBLOCKD to VP9_COMMON.Dmitry Kovalev
VP9_COMMON is the right place to segmentatation struct because it has global segmentation parameters, not something specific to macroblock processing. Change-Id: Ib9ada0c06c253996eb3b5f6cccf6a323fbbba708
2013-08-15Unify luma and chroma rd-cost estimationJingning Han
This commit unifies the rate-distortion cost calculation process of luma and chroma components. It allows early termination to be enabled later in the rd search loop of chroma components, in consistent with luma pixels. Change-Id: I2e52a7c6496176bf2a5e3ef338d34ceb8aad9b3d
2013-08-15Merge "Renaming in MB_MODE_INFO"Paul Wilkins
2013-08-14foreach_transformed_block_in_plane cleanup, explicit tx_size var.Dmitry Kovalev
Making foreach_transformed_block_in_plane more clear (it's not finished yet). Using explicit tx_size variable consistently instead of (ss_txfrm_size / 2) or (ss_txfrm_size >> 1) expression. Change-Id: I1b9bba2c0a9f817fca72c88324bbe6004766fb7d
2013-08-14Renaming in MB_MODE_INFOPaul Wilkins
The macro block mode info context originally contained an entry for each 16x16 macroblock. In VP9 each entry refers to an 8x8 region not a macro block, so the naming is misleading. This first stage clean up changes the names of 3 entries in the structure to remove the mb_ prefix. TODO clean up the nomenclature more widely in respect of mbmi and bmi.

2013-08-12Entropy context related cleanups.Dmitry Kovalev

2013-07-29Remove a redundant branching in tokenize_bJingning Han
The tokenize_b function is only called when output flag is on. Hence removing the conditional branch on it therein. Change-Id: Ib709f47f23f39ca05a695faf86fa3377f11f2dd0
2013-07-29Tune tokenization/detokenization flow for speed-upJingning Han
This commit optimizes the tokenization and detokenization operational flow for speed-up. It makes the coding process about 0.3% faster at speed 0. Change-Id: I28008df7482874e4b5f237f2d418ff82a249dd56
2013-07-29Skip redundant tokenization in rd loopJingning Han
This commit makes the encoder skip the redundant tokenization process in the rate-distortion optimization search loop, while updating the entropy contexts accordingly. It makes the speed 0 encoding process about 0.5% faster at no performance change. Change-Id: I34a4155a0b5332afeb45c93a51c7f35a294d685c

2013-07-24Adding condition inside get_tx_type_{4x4, 8x8, 16x16}.Dmitry Kovalev
Adding plane type check condition because it was always used outside of get_tx_type_{4x4, 8x8, 16x16}. Change-Id: I02f0bbfee8063474865bd903eb25b54d26e07230
2013-07-23Moving counts from FRAME_CONTEXT to new struct FRAME_COUNTS.Dmitry Kovalev
Counts are separate from frame context. We have several frame contexts but need only one copy of all counts. Change-Id: I5279b0321cb450bbea7049adaa9275306a7cef7d
