2013-06-26Make intra predictor reference buffer configurableJingning Han
This commit enables configurable reference buffer pointer for intra predictor. This allows later removal of spatial dependency between blocks inside a 64x64 superblock in the rate-distortion optimization loop. Change-Id: I02418c2077efe19adc86e046a6b49364a980f5b1

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
2013-06-14Merge "Avoid inverse transform/recon without residual"John Koleszar
2013-06-13Avoid inverse transform/recon without residualJohn Koleszar
Avoid calling decode_block, inverse transform/add in the block is a skip block for SBs smaller than 8x8 and intra-coded SBs. Change-Id: I1684182f4a0050c8d6bb46cba6830d9425e7127d

2013-06-11Trap reference frames of invalid sizeJohn Koleszar
A corrupt bitstream could refer to a reference frame that has no size. Change-Id: I56c3b71a9dbb58b498e9969403e289c0e574f948
2013-06-11decode_tiles(): validate buffer readsJohn Koleszar
Previous code indexed using the tile length coded in the bitstream without checking that the read would be valid. Change-Id: Ia5047762223a4f80d75016dd546dc2ef18b6887d
2013-06-11Minor change in forward updatesDeb Mukherjee
Removes the case of coding prob = 0 for forward updates, since that is not an allowed probability to code. Slightly improves efficiency but may not matter in practice. Change-Id: I3b4caf82e8f0891992f0706d4089cc5a27568dba

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
2013-06-10Using network byte order (big-endian) to encode tile size.Dmitry Kovalev
This is consistent with uncompressed header encoding. Change-Id: Iccf40a44b493ed36ee085b81ed56f7952cde70a9
2013-06-10Remove remnants of VP8 profiles/versionsJohn Koleszar
Remove the bilinear filter mode, and the no-loopfilter mode, and the related vp9_setup_version() function. Change-Id: I32311367812faf37863131df3af37d63d03973d7
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
2013-06-08TX_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

2013-06-07Merge "Handle partition type coding of boundary blocks" into experimentalYaowu Xu
2013-06-07Uncompressed header: new encoding for frame sizeDmitry Kovalev
For key frames everything is the same as before. For inter frames we try to reference last/golden/altref frame size. If there is no match then the actual size is encoded. Also we don't allow zero width and height anymore. Change-Id: I49d791fd94af749c823579b0c5ef17c961372678
2013-06-07Frame header changes to support intra_only framesAdrian Grange
Made changes to the frame header to write the sync code in the frame header for a non-displayable, intra-only frame. Extended reset_frame_context to 2-bits. (Submitting on behalf of Dmitri) Change-Id: Ie836ae0df9ed572fb4f08aabe9351a555c4f3b96
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
2013-06-07Cleans up mbskip encodingDeb Mukherjee
Refactors mbskip coding to be compatible with coding of the rest of the symbols. Adds forward/backward adaptation and removes a lot of the legacy code. Results: fast50: +1.6% derfraw300: +0.317% Change-Id: I395a2976d15af044d3b8ded5acfa45f6f065f980

2013-06-07Handle partition type coding of boundary blocksJingning Han
The partition types of blocks sitting on the frame boundary are constrained by the block size and the position of each sub-block relative to the frame. Hence we use truncated probability models to handle the coding of such information. 100 frames run: yt 0.138% Change-Id: I85d9b45665c15280069c0234ea6f778af586d87d
