2013-12-16Converting vp9_treecoder.h to vp9_prob.{h, c}Dmitry Kovalev
Moving vp9_norm probability table from vp9_entropy.c to vp9_prob.c Change-Id: Ie757b73860c6f43130790c332b292e2a1a81b788
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

2013-10-11Replacing {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

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

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

2013-07-17Removing 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

2013-06-10New 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

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.

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

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.

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
2013-04-16Recursive 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

2013-02-20Refactoring of switchable filter search for speedDeb Mukherjee
Refactors the switchable filter search in the rd loop to improve encode speed. Uses a piecewise approximation to a closed form expression to estimate rd cost for a Laplacian source with a given variance and quantization step-size. About 40% encode time reduction is achieved. Results (on a feb 12 baseline) show a slight drop: derf: -0.019% yt: +0.010% std-hd: -0.162% hd: -0.050% Change-Id: Ie861badf5bba1e3b1052e29a0ef1b7e256edbcd0
2013-01-23Adds an error-resilient mode with testDeb Mukherjee
Adds an error-resilient mode where frames can be continued to be decoded even when there are errors (due to network losses) on a prior frame. Specifically, backward updates are turned off and probabilities of various symbols are reset to defaults at the beginning of each frame. Further, the last frame's mvs are not used for the mv reference list, and the sorting of the initial list based on search on previous frames is turned off as well. Also adds a test where an arbitrary set of frames are skipped from decoding to simulate errors. The test verifies (1) that if the error frames are droppable - i.e. frame buffer updates have been turned off - there are no mismatch errors for the remaining frames after the error frames; and (2) if the error-frames are non droppable, there are not only no decoding errors but the mismatch PSNR between the decoder's version of the post-error frames and the encoder's version is at least 20 dB.

2013-01-14Remove compound intra-intra experiment.Ronald S. Bultje
This experiment gives little gains and adds relatively much code complexity (and it hinders other experiments), so let's get rid of it. Change-Id: Id25e79a137a1b8a01138aa27a1fa0ba4a2df274a
2013-01-14Merge prediction filterAdrian Grange
Removed the experimental flag from around the prediction filter. Change-Id: Ic1dd2db8fe8ac17ed5129f83094d4c5cdd5527d2
2013-01-09New prediction filterAdrian Grange
This patch removes the old pred-filter experiment and replaces it with one that is implemented using the switchable filter framework. If the pred-filter experiment is enabled, three interopolation filters are tested during mode selection; the standard 8-tap interpolation filter, a sharp 8-tap filter and a (new) 8-tap smoothing filter. The 6-tap filter code has been preserved for now and if the enable-6tap experiment is enabled (in addition to the pred-filter experiment) the original 6-tap filter replaces the new 8-tap smooth filter in the switchable mode. The new experiment applies the prediction filter in cases of a fractional-pel motion vector. Future patches will apply the filter where the mv is pel-aligned and also to intra predicted blocks. Change-Id: I08e8cba978f2bbf3019f8413f376b8e2cd85eba4
2012-12-18Use standard integer types for pixel values and coefficients.Ronald S. Bultje
For coefficients, use int16_t (instead of short); for pixel values in 16-bit intermediates, use uint16_t (instead of unsigned short); for all others, use uint8_t (instead of unsigned char). Change-Id: I3619cd9abf106c3742eccc2e2f5e89a62774f7da
