2015-06-12vp9_entropymode: make vp9_init_mode_probs privateJames Zern
rename to init_mode_probs Change-Id: Id451d7763b784ed37e43f2c35073a778078d3d0f
2015-05-22Re-worked header filesScott LaVarnway
Various header/test files had to be re-worked in order to build "Remove cm parameter from vp9_decode_block_tokens()". This patch reverts the "Remove cm" part and only contains the re-worked header files. Change-Id: I520958a88d1991fee988a3c784d0eac40e117a32
2015-02-06Make encoder and decoder share common thread functionYunqing Wang
Moved vp9_accumulate_frame_counts to vp9_thread_common.c to eliminate the duplicate code. Change-Id: I9cf506d729603c8bf1494b4c86a3b7d47af1917a
2015-01-30Optimize coef updateYaowu Xu
1. move the check of search method of USE_TX_8X8 up one level to avoid operations of build_tree_distributions() 2. count tx used and avoid computaton for coef udpate when one size is not used at all. Change-Id: Ia3e54a2588aa531c41377a1bfaa64385d04a592c
2014-12-11Prevent decoder from using uninitialized entropy context.Alexander Voronov
If decoding starts with intra-only frame, there is a possibility of using uninitialized entropy context, what leads to undefined behavior. Change-Id: Icbb64b5b1bd1e5de2a4bfa2884e56bc0a20840af
2014-10-07Move inter filter defs to vp9_filter.hJingning Han
Add comments on the use case of these definitions. Further reduce the scope of header file in vp9_context_tree.h. Change-Id: Ic4a7638e838d0ac441b64abfc56e57354c059d75
2014-04-22Renaming MB_PREDICTION_MODE to PREDICTION_MODE.Dmitry Kovalev
Actually, it would be great to have two separate enums INTRA_MODES and INTER_MODES in future. Change-Id: I6c4147cf0002853da9c1e03fe9514eab876f01c8
2014-03-10Adding reusable get_y_mode_prob() function.Dmitry Kovalev

2013-11-26Moving mode encodings from common to encoder + cleanup.Dmitry Kovalev
Change-Id: I248ccb1532e2cd95314d0b95108f2c2e71cf084f
2013-11-04Splitting partition_probs array into two arrays.Dmitry Kovalev
We only update partition_probs for inter frames but they are constant for key frames. It is not necessary to have constants inside frame context and copy them every time. This change reduces FRAME_CONTEXT size by at least 48 bytes. Change-Id: If70a53be51043f37fe7d113853217937710932a7

2013-10-11Adding TREE_SIZE macro + cleanup.Dmitry Kovalev
Using TREE_SIZE for the following trees: vp9_intra_mode_tree vp9_inter_mode_tree vp9_partition_tree vp9_switchable_interp_tree vp9_mv_joint_tree vp9_mv_class_tree vp9_mv_class0_tree vp9_mv_fp_tree Change-Id: I0212bb4c1ee6648249f68517e28a67a56591ee1b
2013-10-11Replacing {VP9_COEF, MODE}_UPDATE_PROB with DIFF_UPDATE_PROB.Dmitry Kovalev
Values of MODE_UPDATE_PROB and VP9_COEF_UPDATE_PROB are equal, so replacing them with one constant. Inlining appropriate arguments for functions: vp9_cond_prob_diff_update (encoder) vp9_diff_update_prob (decoder) Change-Id: I1255a1cb477743b799b3bfbbcd8de6b32b067338

Change-Id: I481d9bb2fa3ec72b6a83d5f04d545ad8013f295c
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
2013-08-05Changing 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
2013-07-30Consistent update for inter_mode probabilities.Dmitry Kovalev
Using inter-mode counts instead of inter-mode-tree branch counts inside FRAME_COUNTS structure. Change-Id: I60dde13af37d06146d7d15543311c1b5044e9e04

2013-07-25General cleanups.Dmitry Kovalev
Removing unused constants, macros, and function declarations. Using ROUND_POWER_OF_TWO macro, vp9_zero, vp9_copy where possible. Moving #include from *.h to *.c. Merging for loops for motion vectors. Change-Id: Ic3bf841764a2bb177128bb3a6d7aa8f68229cd13
2013-07-25Removing vp9_adapt_mode_context function.Dmitry Kovalev

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
2013-07-20Merge "Consistent names for inter mode probabilities and encodings."Dmitry Kovalev
2013-07-19Fixing problem introduced in one of my previous commits.Dmitry Kovalev
Changing fc->tx_probs back to fc->pre_tx_probs. This change actually affects the bitstream but current test vectors work. Chrome branch is not affected at all. Broken since: cc662dd Adding struct tx_probs and struct tx_counts to cleanup the code. Change-Id: I36dd4b3678e902e10aba8dd49b0012eb558c209d
2013-07-19Consistent names for inter mode probabilities and encodings.Dmitry Kovalev
Renaming vp9_sb_mv_ref_tree to vp9_inter_mode_tree, and vp9_sb_mv_ref_encoding_array to vp9_inter_mode_encodings. Change-Id: I0e91fbf81350d3ec5a2599064c74089b5d06133a
2013-07-17Removing kf_{y, uv}_mode_prob arrays from VP9Common.Dmitry Kovalev
These arrays have constant values (no any updates). Removing two corresponding memcpy calls. Making a little cleanup in vp9_entropymode.h as well: removing redundant 'extern' keyword and moving all function declarations at the end. Change-Id: Ia16b38b46aec2e2500f5df29c40a297ae241dede
2013-07-16Moving vp9_kf_default_bmode_probs to vp9_entropymode.c.Dmitry Kovalev

2013-07-12Adding struct tx_probs and struct tx_counts to cleanup the code.Dmitry Kovalev
Also removing unused declarations from vp9_entropymode.h file. Change-Id: Ib9c5826db3584a32f6bb3297a76c522b99d83402
2013-06-10New probs for filters/tx_size and a few othersDeb Mukherjee
* New probs for subpel filters/tx_count * Makes a change to not reset to defaults for the tx_size probs if an intermediate frame reverts to using a fixed tx_size. * A few updates to the parameters for backward adaptation for mode/mv * some cosmetic cleanups derf300: +0.06% Change-Id: I22994d659bc31ca7a4fc8820fde24001e64a2920
2013-06-08TX_SIZE contexts simplification.Deb Mukherjee
Reduces TX_SIZE contexts to 2 for each kind. The code is cleaner and there is hardly any performance difference with more than two contexts. Results: almost neutral Change-Id: I17656bd6db76224ae2856adf882504560e7dbaa4
2013-06-07Coding tx-size selection by use of spatial contextDeb Mukherjee
Adds coding of transform size within a frame by use of context of transform sizes selected in left and above blocks. Also incorporates code for generating stats. TODO: generate and incorporate new default stats Change-Id: I6a7af099f6ad61d448521d9a51167aedaf638ed6
2013-06-07Coding updates for tx-size selectionDeb Mukherjee
Changes to the coding of transform sizes, along with forward and backward probability updates. Results: derf300: +0.241% Context based coding of transform sizes will be in a separate patch. Change-Id: I97241d60a926f014fee2de21fa4446ca56495756
2013-06-06New intra mode and partitioning probabilities.Ronald S. Bultje
Split partition probabilities between keyframes and non-keyframes, since they are fairly different. Also have per-blocksize interframe y intramode probabilities, since these vary heavily between different blocksizes. Lastly, replace default probabilities for partitioning and intra modes with new ones generated from current codec. Replace counts with actual probabilities also. Change-Id: I77ca996e25e4a28e03bdbc542f27a3e64ca1234f
2013-06-05Cosmetic renaming VP9_MVREFS to VP9_INTER_MODESDeb Mukherjee
NO bitstream change Change-Id: I79f6146dac5fdd157051b6f8dc611c0b7b5e5f7f
2013-05-30Merge VP9_YMODES, VP9_UV_MODES, INTRA_MODE_COUNT and cousins.Ronald S. Bultje
These are now merged in a new define called VP9_INTRA_MODES. Change-Id: I0890f895756a7395d84c92f98f43e43f4cf9050d
2013-05-30Merge all intra mode coding trees into a single one.Ronald S. Bultje
Also merge all counters. This removes a few unused probability updates from the bitstream. Change-Id: I20f58853e9dac84d8c0d9703ae012c55917516eb
2013-05-29Remove some unused code related to macroblock/splitmv coding.Ronald S. Bultje
Change-Id: Ic40d56fb162f4e201547dfae33e62ccd9e865889
2013-05-27a few clean-upsYaowu Xu
1. remove prediction mode conversion 2. unified bmode, same for key and non-key frame 3. set I4X4_PRED count for pdf to 0, as I4X4_PRED is no longer coded ever. It is determined by ref_frame and block partition Change-Id: If5b282957c24339b241acdb9f2afef85658fe47d
2013-05-26Remove splitmv.Ronald S. Bultje
Also do per-partition motion vector referencing in <sb8x8 partitions, and adjust mvref finding for sub8x8 partitions. Change-Id: Id3ed1ed4d2a8910d11d327db6cc63b8eb79f941f
2013-05-17Replace default counts with default probs.Paul Wilkins
Replace vp9_kf_default_bmode_counts structure with direct default probabilities. The probability structure is smaller and it removes the need to specify in the bitstream how to convert the counts to probabilities. Note that I have concerns still about the size and value of the large intra mode context. This may cause problems for HW but it also means we rely heavily on reverse update as forwards update of a structure this size is problematic. I intend to review this more generally in the next few days to see if we can come up with a competitive solution that does not rely on such a large context.
