2011-06-09remove one set of 16x16 variance funcationsYaowu Xu
call to this set of functions are replaced by var16x16. Change-Id: I5ff1effc6c1358ea06cda1517b88ec28ef551b0d
2011-06-06remove redundant functionsYaowu Xu
The encoder defined about 4 set of similar functions to calculate sum, variance or sse or a combination of them. This commit removed one set of these functions, get8x8var and get16x16var, where calls to the later function are replaced with var16x16 by using the fact on a 16x16 MB: variance == sse - sum*sum/256 Change-Id: I803eabd1fb3ab177780a40338cbd596dffaed267

2011-05-09Use diamond search to replace full search in full-pixel refining searchYunqing Wang
In NEWMV mode, currently, full search is used as the refining search after n-step search. By replacing it with an iterative diamond search of radius 1 largely reduced the computation complexity, but still maintained the same encoding quality since the refining search is done for every macroblock instead of only a small precentage of macroblocks while using full search. Tests on the test set showed a 3.4% encoding speed increase with none psnr & ssim loss. Change-Id: Ife907d7eb9544d15c34f17dc6e4cfd97cb743d41

2011-04-29changed configure option name to reduce confusionYaowu Xu
Renamed configure option "enable-psnr" to "enable-internal-stats" to better reflect the purpose of the option and eliminate the confusion reported in http://code.google.com/p/webm/issues/detail?id=35 Change-Id: If72df6fdb9f1e33dab1329240ba4d8911d2f1f7a
2011-04-25Merge "keep values in registers during quantization"Johann
2011-04-22Fix overflow in temporal_filter_apply_sse2().Ronald S. Bultje
The accumulator array is an integer array, so use paddd instead of paddw to add values to it. Fixes overflows when using large --arnr-maxframes (>8) values. Change-Id: Iad83794caa02400a65f3ab5760f2517e082d66ae
2011-04-21keep values in registers during quantizationJohann
add an sse4 quantizer so we can use pinsrw/pextrw and keep values in xmm registers instead of proxying through the stack. and as long as we're bumping up, use some ssse3 instructions in the EOB detection (see ssse3 fast quantizer) pick up about a percent on 32bit and about two on 64bit.

2011-04-19modify SAVE_XMM for potential 64bit useJohann
the win64 abi requires saving and restoring xmm6:xmm15. currently SAVE_XMM and RESTORE XMM only allow for saving xmm6:xmm7. allow specifying the highest register used and if the stack is unaligned. Change-Id: Ica5699622ffe3346d3a486f48eef0206c51cf867
2011-04-19Merge "Add save/restore xmm registers in x86 assembly code"Johann
2011-04-18Add save/restore xmm registers in x86 assembly codeJohann
Went through the code and fixed it. Verified on Windows. Where possible, remove dependencies on xmm[67] Current code relies on pushing rbp to the stack to get 16 byte alignment. This broke when rbp wasn't pushed (vp8/encoder/x86/sad_sse3.asm). Work around this by using unaligned memory accesses. Revisit this and the offsets in vp8/encoder/x86/sad_sse3.asm in another change to SAVE_XMM. Change-Id: I5f940994d3ebfd977c3d68446cef20fd78b07877

2011-04-13store quant_shift as an unsigned charJohann
in encodframe.c, quant_shift is set to 0 or 1 in vp8cx_invert_quant only use 8 bits to store this, instead of 16. will allow saving an xmm register in an updated version of the regular quantize Change-Id: Ie88c47fe2aff5af0283dab1147fb2791e4b12f90

2011-04-07fixed an overflow in ssim calculationJim Bankoski
This commit fixed an overflow in ssim calculation, added register save and restore to make sure assembly code working for x64 platform. It also changed the sampling points to every 4x4 instead of 8x8 and adjusted the constants in SSIM calculation to match the scale of previous VPXSSIM.

2011-04-01tweak vp8_regular_quantize_b_sse2Johann
rather than look up rc in the zig zag table, embed it in the macro. this also allows us to shuffle some values in the macro and keep *d in rsi gains of about the same order as the obj_int_extract implementation: ~2% Change-Id: Ib7252dd10eee66e0af8b0e567426122781dc053d

2011-03-21Remove unused vp8_get4x4sse_cs_mmx declarationJohn Koleszar
This declaration did not match the prototype_sad() prototype, but was unused in this translation unit, so it is removed instead. Fixes issue 290. Change-Id: I168854f88a85f73ca9aaf61d1e5dc0f43fc3fdb3
2011-03-17Increase static linkage, remove unused functionsJohn Koleszar
A large number of functions were defined with external linkage, even though they were only used from within one file. This patch changes their linkage to static and removes the vp8_ prefix from their names, which should make it more obvious to the reader that the function is contained within the current translation unit. Functions that were not referenced were removed. These symbols were identified by: $ nm -A libvpx.a | sort -k3 | uniq -c -f2 | grep ' [A-Z] ' \ | sort | grep '^ *1 ' Change-Id: I59609f58ab65312012c047036ae1e0634f795779
