The aom_write_bit() was not calling buf_uabs_write_bit() while the aom_read_bit() function was calling uabs_read_bit(). Change-Id: If98975341472988e8d809aa80a647d7a2531e21e

Calling aom_write_bit() and aom_read_bit() with --enable-daala_ec would call aom_write() and aom_read() with probability 128 which would ultimately call od_ec_enc_bits() and od_ec_dec_bits(). This refactors that code and makes the call explicit. objective-1-fast: master@2016-12-14T18:38:33Z -> daala_ec_bits@2016-12-14T18:36:22Z PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000 0.0000 | 0.0000 | 0.0000 | 0.0000 | 0.0000 | 0.0000 | 0.0000 Change-Id: Ib69e98734fadcdc8b89936b7b6fbd0574afc7e34

The RD_DEBUG experiment computes stats in the _record() functions which then proxy calls through to the actual bit writer. The aom_write_bit_record() should proxy calls through to aom_write_bit() instead of aom_write() with probability 128. Change-Id: I7617fad0f2c25dc05cf111c660a90068c3f4c513

Turned off, by default. TODO: The distortion function of Daala should be added to complete the activity masking working. Note that PVQ QM matrix (i.e. scaler for each band of transform block) is calculated in decoder side as exactly same way in encoder. In Daala, this matrix is written to bitstream and decoder does not generate it. Activity masking can be turned on by setting below flag as 1: Change-Id: I44bfb905cb4e0cad6aa830a4c355cd760a993ffe

Miscellaneous changes. Mostly code simplification and cleanup. Make luma max angle delta depend on block size, which is the way it was before the nextgenv2 branch merge. Also some fixes for compatibility of ext-intra and alt-intra. Change-Id: I2ce869e6ba7dee765a8dc4802f5e88040db3df22

Modifies the C fwd txfms to have correct scaling. Rectangular transforms now are always implemented in a way that the samller side is transformed first. The SSE2 tests are temporarily disabled until the SSSE2 code is modified to be consistent with the C code. Also includes a fdct32 fix. borgtest results show a slight improvement.

The parameters are optimized only on Y, so disable chrominance filtering for now. Later we can extend the syntax to have separate parameters for the chrominance, or optimize the parameters jointly over luminance and chrominance components. lowres: -0.676% (from -0.759%) becomes a little worse midres: -1.837% (from -1.520%) substantial improvement hdres: pending Change-Id: I98d71f48de98394b05fd9036de259cb43d007614

A crash was reported while encoding >1080p file using best mode. (aom issue 107 and issue 108). The cause was that the speed features were initialized using good mode in AV1. The patch(commit f330ca) disabled the upsampled reference usage only for good mode, but not for best mode. So, for 1st key frame, the encoder incorrectly called reset_use_upsampled_references() that caused the segfault. The patch(commit e4e93b) disabled the upsampled reference usage for all encoding modes and resolved the issue. This patch fixed issue 108 and further made sure the upsampled references would be used correctly. BUG=aomedia:108 Change-Id: I8362cc7cd82be324fd77f0bec315aeba509903bd
