2015-07-07Unify subtract function used in VP8/9Jingning Han
This commit replaces the vp8_ prefixed subtract function with the common vpx_subtract_block function. It removes redundant SIMD optimization codes and unit tests. Change-Id: I42e086c32c93c6125e452dcaa6ed04337fe028d9

This allows rate control to react to content of current frame being encoded. Enabling this feature via the setting: screen_content_mode = 2. Change-Id: Ib2c6670551d96f4907495d5b7b76bb8c49e673db

2015-05-07replace DECLARE_ALIGNED_ARRAY w/DECLARE_ALIGNEDJames Zern
this macro was used inconsistently and only differs in behavior from DECLARE_ALIGNED when an alignment attribute is unavailable. this macro is used with calls to assembly, while generic c-code doesn't rely on it, so in a c-only build without an alignment attribute the code will function as expected.

2015-05-06Move shared SAD code to vpx_dspJohann
Create a new component, vpx_dsp, for code that can be shared between codecs. Move the SAD code into the component. This reduces the size of vpxenc/dec by 36k on x86_64 builds. Change-Id: I73f837ddaecac6b350bf757af0cfe19c4ab9327a

2015-03-19vp8: fix a bug in the internal PSNR calculationYunqing Wang
While CONFIG_INTERNAL_STATS=1, PSNR is calculated while encoding. The aligned width/height were used mistakenly in the calculation. This patch fixed it, and used the orignal image width/height. Change-Id: Iad5334f8693af761b71ebb78f2587db8a3404ecf

2014-11-20Correctly initialize "ones" value in neon quantizeJohann
By using 0xff for a short it was not setting the high bits. When comparing the output with vtst to find non-zero elements it was skipping vaules which had no low bits set such as -512 / 0xFE00. Using -8191 as the first element of coeff will generate this condition. BUG=883 Change-Id: Ia1e10fb809d1e7866f28c56769fe703e6231a657
2014-11-06Remove asm offset dependenciesJohann
The obj_int_extract code is no longer worth maintaining. It creates significant issues when adapting for different build systems and no longer offers as significant of a performance benefit due to improvements in intrinsics. Source files will remain until the various third-party builds are updated. The neon fast quantizer has been moved to intrinsics. The armv6 version has been removed because so few remaining targets require it. Compilers and processors have improved significantly since the pack_tokens code was written. The assembly is no longer faster than the C code. pack_tokens were the only optimizations for the armv5te targets so the targets will be removed after the test infrastructure has been updated. BUG=710 Change-Id: Ic785b167cd9f95eeff31c7c76b7b736c07fb30eb

2014-11-04Avoid divide-by-zero in vp8 initializationJohann
Check that the numerator is not zero. If it is, guess 30fps. Fixes a clang IOC error in the quantize test. It's very unlikely for this to occur in the wild because the setup in the quantize test is very nonstandard. Change-Id: Icdab7b81d4e168d3423e14db20787f960052e0c3
2014-10-31Remove pair quantizationJohann
The intrinsics version of the pair quant is slower than running it individually. Change-Id: I7b4ea8599d4aab04be0a5a0c59b8b29a7fc283f4
2014-10-31vp8 quantization -> intrinsicsJohann
Use intrinsics for neon quantization. Slight loss (<5%) of performance compared to the assembly. Roughly 10x faster on arm64 because that was running C code before. Change-Id: I7cf5242d8f29b7eab5bca6a1c20c89c9fc9ca66d
2014-10-24vp8: Updates to noise level estimate.Marco
-Use full bandwidth (when temporal layers is on) for checking switching. -Normalize metric wrt num_blocks. -Rounding fix to update of average noise level metric. -Make default internal denoiser mode == kDenoiserOnYUV (in denoiser set_parameters()). -Adjust some thresholds.

2014-10-08vp8: Suppress denoising with respect to old reference frames.Marco
If the GOLDEN or ALTREF frame was last updated > x frames in the past, don't use them for denoising (only consider LAST). Using an old reference frame for denoising, e.g., if it is a long-term reference or the last key frame, can cause some visible artifacts, in particular in the aggressive denoising mode.
