2014-05-21Renames x86_64 specific asm filesDeb Mukherjee
Renames all x86_64 specific assembly files to consistently end in _x86_64.asm. This will be useful for build systems to handle these files differently. All new 64-bit specific assembly files should use the new naming convention. Change-Id: I36c89584967c82ffc4088b1b5044ac15d2bb7536

2012-11-07Rough merge of master into experimentalJohn Koleszar
Creates a merge between the master and experimental branches. Fixes a number of conflicts in the build system to allow *either* VP8 or VP9 to be built. Specifically either: $ configure --disable-vp9 $ configure --disable-vp8 --disable-unit-tests VP9 still exports its symbols and files as VP8, so that will be resolved in the next commit. Unit tests are broken in VP9, but this isn't a new issue. They are fixed upstream on origin/experimental as of this writing, but rebasing this merge proved difficult, so will tackle that in a second merge commit.

2012-08-31Encoder denoiser performance improvementYunqing Wang
The denoiser function was modified to reduce the computational complexity. 1. The denoiser c function modification: The original implementation calculated pixel's filter_coefficient based on the pixel value difference between current raw frame and last denoised raw frame, and stored them in lookup tables. For each pixel c, find its coefficient using filter_coefficient[c] = LUT[abs_diff[c]]; and then apply filtering operation for the pixel. The denoising filter costed about 12% of encoding time when it was turned on, and half of the time was spent on finding coefficients in lookup tables. In order to simplify the process, a short cut was taken. The pixel adjustments vs. pixel diff value were calculated ahead of time. adjustment = filtered_value - current_raw = (filter_coefficient * diff + 128) >> 8 The adjustment vs. diff curve becomes flat very quick when diff increases. This allowed us to use only several levels to get a close approximation of the curve. Following the denoiser algorithm, the adjustments are further modified according to how big the motion magnitude is. 2. The sse2 function was rewritten. This change made denoiser filter function 3x faster, and improved the encoder performance by 7% ~ 10% with the denoiser on. Change-Id: I93a4308963b8e80c7307f96ffa8b8c667425bf50

2012-06-11Fix pedantic compiler warningsJohn Koleszar
Allows building the library with the gcc -pedantic option, for improved portabilty. In particular, this commit removes usage of C99/C++ style single-line comments and dynamic struct initializers. This is a continuation of the work done in commit 97b766a46, which removed most of these warnings for decode only builds. Change-Id: Id453d9c1d9f44cc0381b10c3869fabb0184d5966

Compares the sum of differences between the input block and the averaged block. If they differ too much the block will not be filtered. Negligible perfomance hit. Change-Id: Ib1c31a265efd4d100b3abc4a1ea6675038c8ddde

2012-03-21Only support improved quantPaul Wilkins
Deprecate fast quant and strict_quant code. Small effect on quality as fast was used in first pass but the effect is basically neutral across the derf set. The rationale here is to reduce the number of code paths for now to make experimentation easier. Optimized and fast code options can be re-introduced later along with other encode speed options.

2012-02-24Bug fix in ssse3 variance computation.Deb Mukherjee

2012-02-23Supporting high precision 1/8-pel motion vectorsDeb Mukherjee
This is the initial patch for supporting 1/8th pel motion. Currently if we configure with enable-high-precision-mv, all motion vectors would default to 1/8 pel. Encode and decode syncs fine with the current code. In the next phase the code will be refactored so that we can choose the 1/8 pel mode adaptively at a frame/segment/mb level. Derf results: http://www.corp.google.com/~debargha/vp8_results/enhinterp_hpmv.html (about 0.83% better than 8-tap interpoaltion) Patch 3: Rebased. Also adding 1/16th pel interpolation for U and V Patch 4: HD results. http://www.corp.google.com/~debargha/vp8_results/enhinterp_hd_hpmv.html Seems impressive (unless I am doing something wrong). Patch 5: Added mmx/sse for bilateral filtering, as well as enforced use of c-versions of subpel filters with 8-taps and 1/16th pel; Also redesigned the 8-tap filters to reduce the cut-off in order to introduce a denoising effect. There is a new configure option sixteenth-subpel-uv which will use 1/16 th pel interpolation for uv, if the motion vectors have 1/8 pel accuracy. With the fixes the results are promising on the derf set. The enhanced interpolation option with 8-taps alone gives 3% improvement over thei derf set: http://www.corp.google.com/~debargha/vp8_results/enhinterpn.html Results on high precision mv and on the hd set are to follow. Patch 6: Adding a missing condition for CONFIG_SIXTEENTH_SUBPEL_UV in vp8/common/x86/x86_systemdependent.c Patch 7: Cleaning up various debug messages. Patch 8: Merge conflict Change-Id: I5b1d844457aefd7414a9e4e0e06c6ed38fd8cc04

2012-02-16Code simplificationPaul Wilkins
Removal of the pickinter.c and .h files and calls to this code. Removal of some code relating to real time and one pass settings though there is more to be done in this regard. However, vp8_set_speed_features() now only supports modes 0 and 1 and speeds up to 3 so rd should always be set. Change-Id: I62c0c1b6154ab499785baef310536080e87bc4d8
