2016-09-16Revert "Restore vp8_sixtap_predict4x4_neon"Johann Koenig
This reverts commit d9dce2f48eed1368a44c368fa87a506bd89ffec5. Appears to be failing the SixtapPredict tests in some configurations and possibly test vectors as well. Change-Id: Ica6aa83ebac47d0a76e451846e7da67b1c17a7d7

2016-09-15Restore vp8_bilinear_predict4x4_neonJohann
This function was removed when clang started introducing alignment hints which caused the 32 bit vld1_lane_u32/vst1_lane_u32 to fail: https://llvm.org/bugs/show_bug.cgi?id=24421 The load has been rendered safe with an implementation ~indiscernible performance-wise that uses _u8 and over-reads just a touch. It is still ~5x faster than C in the unaligned case and doing both filters. BUG=webm:892 BUG=webm:1273 Change-Id: Icf7167189391b46202f47233bb585c24c42bcc36

2016-09-16vp8 postproc: expand CONFIG_POSTPROC guardJohann
postproc.c is overloaded and used for both postproc and internal stats. If only --enable-internal-stats is specified there are issues with non-existent struct members and unused functions. Change-Id: I82367f1ffce659c3918c9f964dbce94a716fbb89

2016-09-15Restore vp8_sixtap_predict4x4_neonJohann
This function was removed when clang started introducing alignment hints which caused the 32 bit vld1_lane_u32/vst1_lane_u32 to fail: https://llvm.org/bugs/show_bug.cgi?id=24421 The load has been rendered safe with an implementation ~indiscernible performance-wise that uses _u8 and over-reads just a touch. The store, when unaligned, has a version that is ~25% slower but safe when xoffset = 0 (second pass filter only). When the first pass filter (or both) are in play, the new version is almost identical in speed. Worst case performance (both filters, unaligned stores) is roughly 3-4x faster than C.

2016-09-09vp8: Set the skin model to mode 1.Marco
This change was reverted before due to a hangouts encode-time regression investigation. But since then this change has been cleared of causing any noticeable regression. This mode reduces some false detection, and uses the same model as in vp9. Change-Id: I9c82a748c5f601d0aca9f61ee218abfbd58c62bd

2016-08-31Define VP8_TEMPORAL_ALT_REF to !CONFIG_REALTIME_ONLYJohann
Previously VP8_TEMPORAL_ALT_REF was only defined for non-realtime-only builds. However, its value was checked with #if, not #ifdef. Fixes -Wundef warnings. BUG=webm:1069 Change-Id: If78d8731298f3f0d3662ffa25f973e7adaf67152

2016-08-25Fix formatting in internal stats for vp8 and vp9Sarah Parker
This corrects a formatting error introduced in: I1e9d548ce445d29002f0c59ebfd3957a6f15e702 where spaces were used as delimiters instead of tabs. The corresponding fix for vp10 is in Ica3d625d6672b3c47e0e208b45eede29b9004030. Change-Id: Ibc4eb8fd82e6b926ba259a679dc98557cadba9b1

vp8_decoder_create_threads() has allocations that expect one is set. Change-Id: I423f2153a2969c88d48ba45cc9ead4a01443ce65
2016-08-23Remove halfpix specializationJohann
This function only exists as a shortcut to subpixel variance with predefined offsets. xoffset = 4 for horizontal, yoffset = 4 for vertical and both for "hv" Removing this allows the existing optimizations for the variance functions to be called. Instead of having only sse2 optimizations, this gives sse2, ssse3, msa and neon. BUG=webm:1273 Change-Id: Ieb407b423b91b87d33c4263c6a1ad5e673b0efd6
2016-08-23vp8: fix decoder crash with invalid leading keyframesJames Zern
decoding the same invalid keyframe twice would result in a crash as the second time through the decoder would be assumed to have been initialized as there was no resolution change. in this case the resolution was itself invalid (0x6), but vp8_peek_si() was only failing in the case of 0x0. invalid-vp80-00-comprehensive-018.ivf.2kf_0x6.ivf tests this case by duplicating the first keyframe and additionally adds a valid one to ensure decoding can resume without error.

2016-08-10Align thread entry point stackAleksey Vasenev
_beginthreadex does not align the stack on 16-byte boundary as expected by gcc. On x86 targets, the force_align_arg_pointer attribute may be applied to individual function definitions, generating an alternate prologue and epilogue that realigns the run-time stack if necessary. This supports mixing legacy codes that run with a 4-byte aligned stack with modern codes that keep a 16-byte stack for SSE compatibility. https://gcc.gnu.org/onlinedocs/gcc/x86-Function-Attributes.html Change-Id: Ie4e4ab32948c238fa87054d5664189972ca6708e Signed-off-by: Aleksey Vasenev <margtu-fivt@ya.ru>

2016-08-03Pad 'Left' when building under ASanJohann
The neon intrinsics are not able to load just the 4 values that are used. In vpx_dsp/arm/intrapred_neon.c:dc_4x4 it loads 8 values for both the 'above' and 'left' computations, but only uses the sum of the first 4 values. BUG=webm:1268 Change-Id: I937113d7e3a21e25bebde3593de0446bf6b0115a
2016-07-28vp8: Switch skin model to mode 0 to save some cycle.JackyChen
