2014-05-15Revert "Remove Wextra warnings from vp9_sad.c"Jim Bankoski
This reverts commit 7ab9a9587b96db4edce6be916c1f02297a9555ff Nightly test http://build.webmproject.org/jenkins/view/libvpx-nightly-tests/job/libvpx%20unit%20tests%20(valgrind-2)/arch=x86_64-linux-gcc,filter=-*VP8*:*Large.*/276/console Failed This patch did not address all the assembly issues some of the vp8 assembly counts on 5 arguments being passed in to this function: one example : vp8_sad8x16_wmt Please address or split this into vp9 and vp8 patches.

2014-05-14Remove Wextra warnings from vp9_sad.cDeb Mukherjee
As a side-effect, the max_sad check is removed from the C-implementation of VP8, for consistency with VP9, and to ensure that the SAD tests common to VP8/VP9 pass. That will make the VP8 C implementation of sad a little slower but given that is rarely used in practice, the impact will be minimal. Change-Id: I7f43089fdea047fbf1862e40c21e4715c30f07ca

2013-10-16Implement variance-based adaptive quantizationGuillaume Martres
This should be similar to what x264 does with --aq-mode 1. It works well with clips like parkjoy and touhou (http://x264.nl/developers/Dark_Shikari/LosslessTouhou.mkv). At low bitrates, the segmentation signaling overhead may negate the benefits of this feature. (PGW) Default changed to feature OFF to allow provisional merge.

2013-06-25Add averaging-SAD functions for 8-point comp-inter motion search.Ronald S. Bultje
Makes first 50 frames of bus @ 1500kbps encode from 3min22.7 to 3min18.2, i.e. 2.3% faster. In addition, use the sub_pixel_avg functions to calc the variance of the averaging predictor. This is slightly suboptimal because the function is subpixel-position-aware, but it will (at least for the SSE2 version) not actually use a bilinear filter for a full-pixel position, thus leading to approximately the same performance compared to if we implemented an actual average-aware full-pixel variance function. That gains another 0.3 seconds (i.e. encode time goes to 3min17.4), thus leading to a total gain of 2.7%. Change-Id: I3f059d2b04243921868cfed2568d4fa65d7b5acd

2013-05-10Add joint motion search in comp_inter_inter mode(experiment)Yunqing Wang
In current code, motion vectors got from single prediction mode are used in compound prediction mode directly. These motion vectors may not give accurate prediction since they are searched independently. In this patch, we took Pascal's suggestion, and did joint motion search in compound prediction mode to find better motion vectors in this situation. Test results: Overall PSNR: 0.570%(derf), 0.918%(stdhd); SSIM: 0.572%(derf), 1.009%(stdhd); The encoder is a little slower. This can be improved since some c code is used in motion search.

2013-02-28this commit converts all sad ptrs to uint32Jim Bankoski
sse4_1 code used uint16_t for returning sad, but that won't work for 32x32 or 64x64. This code fixes the assembly for those and also reenables sse4_1 on linux Change-Id: I5ce7288d581db870a148e5f7c5092826f59edd81
2013-02-27Remove unused vp9_copy32xnJohn Koleszar
This function was part of an optimization used in VP8 that required caching two macroblocks. This is unused in VP9, and might not survive refactoring to support superblocks, so removing it for now. Change-Id: I744e585206ccc1ef9a402665c33863fc9fb46f0d

For coefficients, use int16_t (instead of short); for pixel values in 16-bit intermediates, use uint16_t (instead of unsigned short); for all others, use uint8_t (instead of unsigned char). Change-Id: I3619cd9abf106c3742eccc2e2f5e89a62774f7da
