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

2013-06-11Merge "Disallow wide loopfilter on some chroma borders" into experimentalJohn Koleszar
2013-06-11Disallow wide loopfilter on some chroma bordersJohn Koleszar
Don't do the 15 tap filter if there aren't 8 pixels below/right of the edge. Change-Id: I62f16437c1d9ba59b6901a5fe71ddb2f472da344
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
2013-06-11Fix rd partition search for corner blocksJim Bankoski
This commit enables proper partition type search for the bottom- right corner blocks. Change-Id: Id1123d0e4e81eba648ed4f3c0c7ab587e174f650
2013-06-10Fix partition coding of corner blockJingning Han
This commit fixed the allowable partition types for bottom-right corner blocks. When a block has over half of its pixels as valid content in both vertical and horizontal directions, allow all the four partition types in the bit-stream. Otherwise, apply partition type constraints. Change-Id: I2252e2de7125a8bfb1c824bf34299a13c81102e3
2013-06-10Adds a zero check in model_rd functionDeb Mukherjee
Avoids divide-by-zero when variance is 0. Change-Id: I3c7f526979046ff7d17714ce960fe81d6e1442a0

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

2013-06-10Cosmetic cleanups of filtersDeb Mukherjee
No bitstream change. Removes unused filters and the code for the case of 2 switchable filters; also changes the 8tap-smooth filter coefficients for integer shifts to be interpolating to be consistent with the way it is implemented currently. Change-Id: I96c542fd8c06f4e0df507a645976f58e6de92aae
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

2013-06-10Fix use of get_uv_tx_size in loopfilterJohn Koleszar
Change the argument of get_uv_tx_size() to be an MBMI pointer, so that the correct column's MBMI can be passed to the function. Change-Id: Ied6b8ec33b77cdd353119e8fd2d157811815fc98

2013-06-10Merge "Loopfilter: bug fix in sb_type usage" into experimentalYaowu Xu
2013-06-10Fixed point reference picture scalingTero Rintaluoma
Fixed point scaling factors are calculated once for each reference frame by using integer division. Otherwise fixed point scaling routines are used in all scaling calculations. This makes it possible to calculate fixed point scaling factors on device driver software and pass them to hardware and thus avoid division on hardware. TODO: - Missing check for maximum frame dimensions (currently scaling uses 14 bits) - Missing check for maximum scaling ratio (upscaling 16:1, downscaling 2:1) Problems: - Straightforward fixed point implementation can cause error +-1 compared to integer division (i.e. in x_step_q4). Should only be an issue for frames larger than 16k. Change-Id: I3cf4dabd610a4dc18da3bdb31ae244ebaf5d579c
