2015-06-04Reducing size of MODE_INFO structScott LaVarnway
Reduced size from 124 bytes to 104 bytes. For decode only builds, it is reduced to 68 bytes. Change-Id: If9e6b92285459425fa086ab5a743d0a598a69de3
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
2015-01-14Add encoder control for setting color spaceYaowu Xu
This commit adds encoder side control for vp9 to set color space info in the output compressed bitstream. It also amends the "vp9_encoder_params_get_to_decoder" test to verify the correct color space information is passed from the encoder end to decoder end. Change-Id: Ibf5fba2edcb2a8dc37557f6fae5c7816efa52650
2014-11-06Change the use of a reserved color space entryYaowu Xu
This commit rename a reserved color space entry to BT_2020, it intends to provide support for VP9 bitstream to pass along the color space type defined in BT.2020(Rec.2020) please note this entry does not have any effect on encoding/decoding behavior, but allow applications to the pass the information along from encoding end to decoding end.

2014-10-07Remove vp9_blockd.h from vp9_common_data.cJingning Han
The basic data defs should be above block operation level. Change-Id: I7dd9836d01120ab75e0c472baac9f15495ed0db5
2014-09-02Adds config opt for highbitdepth + misc. vpxDeb Mukherjee
Adds config parameter vp9_highbitdepth, to support highbitdepth profiles. Also includes most vpx level high bit-depth functions. However encode/decode in the highbitdepth profiles will not work until the rest of the code is in place. Change-Id: I34c53b253c38873611057a6cbc89a1361b8985a6
2014-08-07Changes hdr for profiles > 1 for intraonly framesDeb Mukherjee
Specifies the bit-depth, color sampling and colorspace for intra only frames for profiles > 0 Also adds checks to ensure that profile 1 and 3 are exclusively used for non 420 streams. Change-Id: Icfb15fa1acccbce8f757c78fa8a2f60591360745

2014-07-17Separates profile 2 into 2 profiles 2 and 3Deb Mukherjee
Separates HBD profile int two profiles (2 and 3) consistent with the highbitdepth branch. This patch is ported from the original highbitdepth branch patch: https://gerrit.chromium.org/gerrit/#/c/70460/ Two of the invalid file tests needed to be updated. Change-Id: I6a4acd2f7a60b1fb4cbcc8e0dad4eab4248431e3
2014-04-08High-level hooks for Profile 2 (10/12 bit)Deb Mukherjee
Adds some high-level hooks for profile 2 before further progress on the implementation. According to the definitiion in this patch: 1. Profile 2 only supports 10 or 12 bit color but not 8 2. Profile 2 supports all color sampling modes: 444, 422 and 420, and alpha plane. 3. Profile 3 is currently undefined. Please consider the definition carefully and suggest modifications to the definition as needed. Change-Id: I5b284fc679e54ac5aee171af72fa7994cfd28995

Change-Id: I62bb07c377f947cb72fac68add7a6b199e42c6b9
2013-08-26Renaming BLOCK_SIZE_TYPE to BLOCK_SIZE in the common/decoder.Dmitry Kovalev
Adding temporary "typedef BLOCK_SIZE BLOCK_SIZE_TYPE" which will go away after encoder's patch. Change-Id: I06ec6a6f079401439843ec981d1496234fd7775c
2013-08-23Limit mv range to be based on partition sizeYaowu Xu
Previous change c4048dbd limits the mv search range assuming max block size of 64x64, this commit change the search range using actual block size instead. Change-Id: Ibe07ab02b62bf64bd9f8675d2b997af20a2c7e11
2013-08-22rename LOG2_* defines to *_LOG2James Zern
gets rid of a mix of styles Change-Id: I3591d312157bc6f53a25438bf047765c671fd8a8
2013-08-19Change to limit the mv search rangeYaowu Xu
As the pixel values beyond image border are duplicates of pixels on edge, the change limits the mv search range, any mv beyond the limits no longer produce new/different prediction values as entire block with pixels used for subpel interpolation are outside image border. Change-Id: I4c6fdf06e33c1cef1489f5470ce0fb4e5e01fb79
2013-08-09Renaming BLOCK_SIZE_TYPES constant to BLOCK_SIZES.Dmitry Kovalev
There will be another change set to rename BLOCK_SIZE_TYPE enum to BLOCK_SIZE. Change-Id: I8d1dfc873d6186fa5e554262f5169e929978085e
2013-08-07Adding ss_size_lookup table.Dmitry Kovalev
Removing the old one bsize_from_dim_lookup. Now we have a way to determine block size for plane using its subsampling values (ss_size_lookup). And then we can find the number of pixels in the block (num_pels_log2_lookup). Change-Id: I6fc981da2ae093de81741d3d78eaefed11015db9

2013-07-23clean up bw, bhJim Bankoski
many structures use bw and bh and they have different meanings. This cl attempts to start this clean up and remove unneccessary 2 step look up log and then shift operations... also removed partition type multiple operation code in bitstream.c. Change-Id: I7e03e552bdfc0939738e430862e3073d30fdd5db
2013-07-19Renaming TXFM_MODE to TX_MODE (like TX_SIZE, TX_TYPE).Dmitry Kovalev
Moving TX_MODE enum to vp9_enums.h. Renaming txfm_mode variables to tx_mode. Change-Id: I459d1af6dd928ce7fccdf8ce30b6f1ca057bef92
2013-07-12Some minor cleanups for efficiencyDeb Mukherjee
Implements some of the helper functions more efficiently with lookups rathers than branches. Modeling function is consolidated to reduce some computations. Also merged the two enums BLOCK_SIZE_TYPES and BlockSize into one because there is no need to keep them separate (even though the semantics are a little different). No bitstream or output change. About 0.5% speedup Change-Id: I7d71a66e8031ddb340744dc493f22976052b8f9f
2013-07-08Using mi_cols instead of mb_cols.Dmitry Kovalev

2013-06-05Moving bits from compressed header to uncompressed one.Dmitry Kovalev
Bits moved: refresh_frame_flags, active_ref_idx[], ref_frame_sign_bias[], allow_high_precision_mv, mcomp_filter_type, ref_pred_probs[]. Derf results: +0.040% Change-Id: I011f43c7eac0371d533b255fd99aee5ed75b85a5
2013-05-23Merge 4x4 block level partition into codebaseJingning Han
Move 4x4/4x8/8x4 partition coding out of experimental list. This commit fixed the unit test failure issues. It also resolved the merge conflicts between 4x4 block level partition and iterative motion search for comp_inter_inter. Change-Id: I898671f0631f5ddc4f5cc68d4c62ead7de9c5a58
2013-05-14Enable recursive partition down to 4x4Jingning Han
This commit allows the rate-distortion optimization recursion at encoder to go down to 4x4 block size. It deprecates the use of I4X4_PRED and SPLITMV syntax elements from bit-stream writing/reading. Will remove the unused probability models in the next patch. The partition type search and bit-stream are now capable of supporting the rectangular partition of 8x8 block, i.e., 8x4 and 4x8. Need to revise the rate-distortion parts to get these two partition tested in the rd loop. Change-Id: I0dfe3b90a1507ad6138db10cc58e6e237a06a9d6
2013-05-10Add joint motion search in comp_inter_inter mode(experiment)Yunqing Wang
In current code, motion vectors got from single prediction mode are used in compound prediction mode directly. These motion vectors may not give accurate prediction since they are searched independently. In this patch, we took Pascal's suggestion, and did joint motion search in compound prediction mode to find better motion vectors in this situation. Test results: Overall PSNR: 0.570%(derf), 0.918%(stdhd); SSIM: 0.572%(derf), 1.009%(stdhd); The encoder is a little slower. This can be improved since some c code is used in motion search. Change-Id: Ib30c9240f6c56c9b070867b4ca89412a76d9f3c6
2013-05-08Extend left/above partition context to per mi(8x8)Jingning Han
Update and buffer left/above partition information context per 8x8 block. This allows to further enable recursive partition down to 4x4 block size, and hence deprecating I4X4_PRED and SPLITMV. This commit also fixes a context buffer swap/restore issue in 32x32 partition type search. This gives 0.1% performance gain for derf/yt. Will refactor the superblock partition type search into recursion form. Change-Id: Ib61975aca5f12b78d8018481d7fa1393d085689b
2013-05-07Add building blocks for partition down to 4x4Jingning Han

2013-05-07Merge SB8X8 into the codebaseJingning Han
Pull sb8x8 out of experimental list. verified via borg run tests. Fixed unit test failures. Change-Id: I12a4bbd17395930580c048ab68becad1ffe46e76
2013-04-30sb8x8 integration in rd loop.Ronald S. Bultje
Work-in-progress, not yet ready for review. TODO items: - bitstream writing (encoder) and reading (decoder) - decoder reconstruction Change-Id: I5afb7284e7e0480847b47cd0097cb469433c9081
2013-04-29Separate I4X4_PRED coding from macroblock modulesJingning Han
Separate the functionality of I4X4_PRED from decode_mb. Use decode_atom_intra instead, to enable recursive partition of superblock down to 8x8. Change-Id: Ifc89a3be82225398954169d0a839abdbbfd8ca3b

Move rectangular superblock coding out of experimental list. Change-Id: I96c37547d122330d666a67b4bf577ae54547857f
2013-04-24Contextual entropy coding of partition syntaxJingning Han
This commit enables selecting probability models for recursive block partition information syntax, depending on its above/left partition information, as well as the current block size. These conditional probability models are reasonably stationary and consistent across frames, hence the backward adaptive approach is used to maintain and update the contextual models. It achieves coding performance gains (on top of enabling rectangular block sizes): derf: 0.242% yt: 0.391% hd: 0.376% stdhd: 0.645% Change-Id: Ie513d9673337f0d27abd65fb566b711d0844ec2e
2013-04-23Add basic building blocks for 8x8 superblocks experiment.Ronald S. Bultje
Change-Id: I274a1d2e461e6ffdb106bac4ad6951692ace314e
2013-04-16Recursive partition syntax codingJingning Han
Enable recursive partition information coding from SB64X64 down to MB16X16. The bit-stream syntax is now supporting rectangular block sizes. It starts from SB64X64 and recursively describes the partition type of the current block. If the partition type is PARTITION_NONE, the block is coded as a single unit; if it is PARTITION_HORZ or PARTITION_VERT, the block is segmented into two independently coded rectangular units, with no further partition needed; otherwise, the block is segmented into 4 square blocks. i.e., PARTITION_SPLIT case, each can be potentially further partitioned. Forward adaptive probability modeling is used for the partition information coding, conditioned on the current block size. Change-Id: I499365fb547839d555498e3bcc0387d8a3587d87
2013-04-09Make SB coding size-independent.Ronald S. Bultje
Merge sb32x32 and sb64x64 functions; allow for rectangular sizes. Code gives identical encoder results before and after. There are a few macros for rectangular block sizes under the sbsegment experiment; this experiment is not yet functional and should not yet be used.
