2015-02-05Fix high bit depth assembly function bugsYunqing Wang
The high bit depth build failed while building for 32bit target. The bugs were in vp9_highbd_subpel_variance.asm and vp9_highbd_sad4d_sse2.asm functions. This patch fixed the bugs, and made 32bit build work. Change-Id: Idc8e5e1b7965bb70d4afba140c6583c5d9666b75
2015-01-27Fix issues in 32bit PIC enabled buildYunqing Wang
This patch was to fix issue 924: https://code.google.com/p/webm/issues/detail?id=924 The SECTION_RODATA macro was modified to support macho32 format. The sub-pixel functions were modified to pass in 2 more parameters to handle the global offsets for PIC build. Change-Id: I3bfcd336bcae945edf300bca4ab40376a2628cd4

2014-12-03Enable non-rd mode coding on key frame, for speed 6.Marco
For key frame at speed 6: enable the non-rd mode selection in speed setting and use the (non-rd) variance_based partition. Adjust some logic/thresholds in variance partition selection for key frame only (no change to delta frames), mainly to bias to selecting smaller prediction blocks, and also set max tx size of 16x16. Loss in key frame quality (~0.6-0.7dB) compared to rd coding, but speeds up key frame encoding by at least 6x. Average PNSR/SSIM metrics over RTC clips go down by ~1-2% for speed 6.

This commit reworks the forward transform and quantization process for 8x8 block coding. It combines the two operations in a single function to save a store/load stage of the original transform coefficients. Overall the speed -6 is slightly faster (around 1% range). The compression performance of speed -6 is improved by 3.4%. Change-Id: Id6628daef123f3e4649248735ec2ad7423629387

2014-10-07experimental : partition using 1/8 x 1/8 imageJim Bankoski
The concept: There's too much noise in source pixels for variance and at low bitrate the reconstructed looks nothing like the source so we have problems getting good partitionings with either. This skirts the issue by using a box blur scaled down version for variance calculations. To compare against source_var_ moved keyframe to be rd based like source_var.

2014-10-06Add SSE2 code and unit test for VP9 denoiser.JackyChen
This SSE2 is based on VP8 denoiser's SSE2 code. In VP8, there are only 16x16 blocks in denoiser, while in VP9, there are 13 different block sizes. By adding this SSE2 code, the improvement of encoder speed is around 20%(using C code vs using SSE2 code), vary for different clips. The unit test for VP9 denoiser is to confirm that the SSE2 code is bit-exact with the C code. The unit test covers all block size. Change-Id: Ic8d8ac26db4ea40a5f146b5678a065af07eaaa3d
