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).

2013-08-23Renaming D27 to D207.Dmitry Kovalev
I've already renamed d27_predictor to d207_predictor but forgot about the corresponding constant. Change-Id: Id312aa80fc5b5a1ab8a709a33418a029552a6857

2013-08-15Renaming d27 predictor to d207.Dmitry Kovalev
27 degrees intra predictor is actually 207 degrees, so renaming it. Change-Id: Ife96a910437eb80ccdc0b7a5b7a62c77542ae5be
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
2013-08-09Moving loopfilter struct to VP9_COMMON.Dmitry Kovalev
Loop filter configuration doesn't belong to macroblock, so moving it from MACROBLOCKD to VP9_COMMON. Also moving the declaration of loopfilter struct from vp9_blockd.h to vp9_loopfilter.h. Change-Id: I4b3e34be9623b47cda35f9b1f9951f8c5b1d5d28
2013-08-08General code cleanup.Dmitry Kovalev
Removing redundant parenthesis and curly braces. Combining declarations with initializations. Adding useful intermediate variables instead of recalculating expressions every time. Change-Id: I00106f404afd60bfc189905b0fded881684f941a
2013-08-05Changing the order switchable filter enum constants.Dmitry Kovalev
This changeset allows to remove vp9_switchable_interp and vp9_switchable_interp_map arrays and make code much clear. Actually we still have to use these mapping but only inside read_interp_filter_type and write_interp_filter_type functions. Change-Id: I4026c6f8c4acefba6c81421b7bacbaa52cc45f50

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
2013-07-23Removing vp9_is_interpolating_filter array.Dmitry Kovalev
All filters are interpolating now, so we don't need this array, all values from this array are evaluated to true. Change-Id: I9af6d8219ae0eb984063cd15e4e2296374ae4961

2013-07-22Using update_ct and update_ct2 functions for probability update.Dmitry Kovalev
Update logic for both mode and mvref was the same, so using MODE_COUNT_SAT, MODE_MAX_UPDATE_FACTOR, update_ct, update_ct2 for both cases. Removing function update_tx_ct because it was identical to update_mode_ct2. Change-Id: Iff566be27dbd6cde4c2ec04e8d988f207046b8f0

2013-06-10Cosmetic cleanups of filtersDeb Mukherjee
No bitstream change. Removes unused filters and the code for the case of 2 switchable filters; also changes the 8tap-smooth filter coefficients for integer shifts to be interpolating to be consistent with the way it is implemented currently. Change-Id: I96c542fd8c06f4e0df507a645976f58e6de92aae
2013-06-10Implement intra-coded framesAdrian Grange
Implements ability to signal and decode frames that are encoded using only intra coding modes. Only the decode side has been implemented here. Change-Id: I53ac6a8d90422cd08ba389e5236e15b45f9e93de
