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
2013-11-05Localizing NEARESTMV special cases in the code.Dmitry Kovalev
Removing special case handling from vp9_tree_probs_from_distribution(), tree_merge_probs(), and vp9_tokens_from_tree_offset() functions. Replacing inter_mode_offset() function with macro INTER_OFFSET which is used now for vp9_inter_mode_tree definition. Change-Id: Iff75a1499d460beb949ece543389c8754deaf178
2013-11-01Removing 'new' probability calculation from convert_distribution().Dmitry Kovalev
We don't have to calculate 'new' probability in convert_distribution() because it is enough to calculate only 'new' counters which could be used to calculate probability if necessary. That's why removing a lot of unused temporary probability arrays and reducing number of get_binary_prob() calls. Change-Id: I4e14eb7203d1ace61bbddefd6b9b6326be83ba63
2013-10-16Merge "Using constants instead of plain numbers."Dmitry Kovalev
2013-10-15Updated encoder to handle intra-only framesAlexander Voronov
Updated the encoder to handle frames that are coded intra-only. Intra-only frames must be non-showable, that is, the "show frame" flag must be set to 0 in the frame header. Tested by forcing the ARF frames to be coded intra- only. Note: The rate control code will need to be modified to account for intra-only frames better than they are currently handled.

Now we have entropy code separate from scan/iscan code. The next step in future is to move iscan code from common part to the encoder. Change-Id: Id9732f7d80aec00af35c1d58d1137c4c96c91451

2013-07-01Make get_coef_context() branchless.Ronald S. Bultje
This should significantly speedup cost_coeffs(). Basically what the patch does is to make the neighbour arrays padded by one item to prevent an eob check in get_coef_context(), then it populates each col/row scan and left/top edge coefficient with two times the same neighbour - this prevents a single/double context branch in get_coef_context(). Lastly, it populates neighbour arrays in pixel order (rather than scan order), so we don't have to dereference the scantable to get the correct neighbours. Total encoding time of first 50 frames of bus (speed 0) at 1500kbps goes from 2min10.1 to 2min5.3, i.e. a 2.6% overall speed increase. Change-Id: I42bcd2210fd7bec03767ef0e2945a665b851df56
2013-07-01Quantize (64-bit only, for now) SSSE3 SIMD.Ronald S. Bultje
Total encoding time for first 50 frames of bus (speed 0) @ 1500kbps goes 2min34.8 to 2min14.4, i.e. a 10.4% overall speedup. The code is x86-64 only, it needs some minor modifications to be 32bit compatible, because it uses 15 xmm registers, whereas 32bit only has 8. Change-Id: I2df53770c2e850813ffa713e1a91b45b0082b904
2013-06-28Inline vp9_get_coef_context() (and remove vp9_ prefix).Ronald S. Bultje
Makes cost_coeffs() a lot faster: 4x4: 236 -> 181 cycles 8x8: 888 -> 588 cycles 16x16: 3550 -> 2483 cycles 32x32: 17392 -> 12010 cycles Total encode time of first 50 frames of bus (speed 0) @ 1500kbps goes from 2min51.6 to 2min43.9, i.e. 4.7% overall speedup.

2013-06-24Move vp9_full_to_model_counts to encoderJohn Koleszar
This function is not called from the decoder, so it doesn't need to be in common/. Change-Id: I6977dd462a25b4ff39c9c7e1b0b5b16aa58ee733

This function never referenced. Change-Id: I1c42cd355bfa88e17d169f7335a44be682af58cc
2013-06-14Remove constant vp9_coef_update_prob tableJohn Koleszar
All elements of this table are equal to 252, so replace it with a single constant VP9_COEF_UPDATE_PROB. Change-Id: I1e2d1d284326ce6df9899a740c2fc344b3ec81c9
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

2013-05-30Replace scatter scan 32x32 with HW friendly scan.Sami Pietila
The first 240 coeff positions (15 top-left blocks) are scanned in the same order as in scatter scan, after that the coeffs are scanned in "block bands", each band at a time, all coeffs in one band before moving on to the next band. This brings down the amount of 4x4 coeff blocks that need to be buffered while scanning, from 15 blocks to 8 blocks. Change-Id: I478a991d63c48bd5e64d36e59fed7a00c9a651ba
2013-05-29Balancing coef-tree to reduce bool decodesDeb Mukherjee
This patch changes the coefficient tree to move the EOB to below the ZERO node in order to save number of bool decodes. The advantages of moving EOB one step down as opposed to two steps down in the other parallel patch are: 1. The coef modeling based on the One-node becomes independent of the tree structure above it, and 2. Fewer conext/counter increases are needed. The drawback is that the potential savings in bool decodes will be less, but assuming that 0s are much more predominant than 1's the potential savings is still likely to be substantial. Results on derf300: -0.237% Change-Id: Ie784be13dc98291306b338e8228703a4c2ea2242
2013-05-29Residual coding to cache energy class of tokens.Sami Pietila
Proposal for tuning the residual coding by changing how the context from previous tokens is calculated. Storing the energy class of previous tokens instead of the token itself eases the critical path of HW implementations. Change-Id: I6d71d856b84518f6c88de771ddd818436f794bab
