2016-05-25Fix comments in build_intra_predictors_high()Yaowu Xu
1. Removed TODOs, no longer applicable to finalized vp9 profiles. 2. Added explanation on assumed values for highbitdepth profiles. Change-Id: I59e0bebaaab900cc611ed284daa5fa0bdedb8097

2015-07-31Code refactor on InterpKernelZoe Liu
It in essence refactors the code for both the interpolation filtering and the convolution. This change includes the moving of all the files as well as the changing of the code from vp9_ prefix to vpx_ prefix accordingly, for underneath architectures: (1) x86; (2) arm/neon; and (3) mips/msa. The work on mips/drsp2 will be done in a separate change list. Change-Id: Ic3ce7fb7f81210db7628b373c73553db68793c46

2015-07-13Refactor intra block prediction functionJingning Han
This commit simplifies the intra block boundary condition logic. It removes the block index from the argument set. Change-Id: If00142512eb88992613d6609356dfd73ba390138

2015-06-04vp9_reconintra: simplify d63_predictorJames Zern
calculate the averages needed for even and odd rows once; this removes a conditional from the inner loop the final average calculated currently relies on above[] being extended, it could be reduced to use above[block_size - 2] + 3 * above[block_size - 1] Change-Id: I70f5eac8d8a2a959c7114844a95826f445c3dd4d

2015-05-13Relocate memory operations for common codeJohann
With the sad functions, and hopefully the variance functions soon, moving to the vpx_dsp location, place the defines used in the reference C code in a common location. Change-Id: I4c8ce7778eb38a0a3ee674d2f1c488eda01cfeca
2015-05-08build_intra_predictors*: reduce above_data sizeJames Zern
currently this needs to be 2x (NEED_ABOVERIGHT) the size of the largest block (32) + 1 (for above_left). reduce the buffer size from 128 + 16 (alignment) to 64 + 16. Change-Id: Idaca1806c7e1214e9437de24e15edc2ebf18f95d
2015-05-07build_intra_predictors*: reduce left_col sizeJames Zern
this should only need to be the size of the largest block, i.e., 32, not 64. Change-Id: Ib8cb2424771fdd2a64c55379597248b2722a5ceb
2015-05-07replace DECLARE_ALIGNED_ARRAY w/DECLARE_ALIGNEDJames Zern
this macro was used inconsistently and only differs in behavior from DECLARE_ALIGNED when an alignment attribute is unavailable. this macro is used with calls to assembly, while generic c-code doesn't rely on it, so in a c-only build without an alignment attribute the code will function as expected.

This speeds up a normal YT style 1080P clip decode by ~1% on nexus 7. Change-Id: Ied7fa0d8bc941b2adb4db9382f549ee4d5654f3a
2015-03-04Declare function used by 'once' with 'void' parametersJohann
Visual Studio is exceptionally picky about this: vp9_reconintra.c(900): warning C4113: 'void (__cdecl *)()' differs in parameter lists from 'void (__cdecl *)(void)' [.build-x86_64-win64-vs10\vpx.vcxproj] Change-Id: I564c7415f4608fd962be8c699d6133a996b545f7
2015-03-03fix a race condition caused by intra function pointer initializationYunqing Wang
This patch fixed webm issue 962. (https://code.google.com/p/webm/issues/detail?id=962) The data races occurred when an encoder and a decoder were created at the same time, and the function pointers were initialized twice. Change-Id: I8851b753c4b4ad4767d6eea781b61f0ac9abb44b

2014-10-03Incorporate WRAPLOW macro into non-highbitdepth txDeb Mukherjee
Incorporates the WRAPLOW macro into the non-highbitdepth transforms to aid hardware verification between a software C model and an intended hardware implementation though the use of the configure options: --enable-experimental --enable-emulate-hardware. Note that to avoid further discrepancies between the sse/sse2 implementations of the transforms and the C implementation, when the emulate hardware option is invoked, we also disable sse/sse2/etc. Also incudes some minor cleanups/renaming etc. Change-Id: Ib864d8493313927d429cce402982f1c8e45b3287

2014-05-13Silience -wextra warnings in vp9_reconintra.cJingning Han
The warning messages complained that there are unused arguments in a few prediction modes. This structure was designed on purpose, such that a wrapper function can cover all prediction mode cases and make them readily accessible as an pointer array. This commit silences such warnings.
