2013-09-11Improved 8t filtersScott LaVarnway
Reformatted version of a patch submitted by Erik/Tamar from Intel. For the test clips used, the decoder performance improved by ~2%. Change-Id: Ifbc37ac6311bca9ff1cfefe3f2e9b7f13a4a511b
2013-09-11Changes in speed 2 settingsDeb Mukherjee
Propose some changes to the speed 2 settings to improve quality. In particular, turns off the adjust_thresholds_by_speed feature which improves results by 6%. Also removes the code for adjust_thresholds_by_speed since it conflicts with the adaptive rd thresh feature. Overall, with this change speed 2 is -15.2% from speed 0 settings, on derf, which is significantly better than -21.6% down before. Change-Id: I6e90a563470979eb0c258ec32d6183ed7ce9a505

2013-09-10Remove redundant condition check in 32x32 quantJingning Han
The c code implementation of 32x32 quantization does the zbin check of all coefficients prior to the quant/dequant loop, hence removing the redundant zbin check inside the loop. This only affects the c code version. SSSE3 version does not separate the zbin check out. Change-Id: Ic197a7d61d0b25fcac3cc092987651378cb56e4e
2013-09-10Enable and fix resize_test for VP9Adrian Grange
Added the resize_test unit test to the VP9 set. Set g_in_frames = 0 to avoid a problem when the total number of frames being encoded is smaller than g_in_frames. In this case the test will not have access to the encoded frames and will not be able to compare them for testing for encoder/decoder mismatch. Change-Id: I0d2ff8ef058de7002c5faa894ed6ea794d5f900b

Improves results a little. derf is now +1.078% over bitrate control. Change-Id: I4812136f3e67be21d14ec089419976a32a841785
2013-09-10Stop partition checking when distortion is smallYunqing Wang
If the current obtained distortion is very small, which happens for static image case, we pick the current partition type without further split checking. This won't affect regular videos. For static videos, we got 10%~12% encoding speed gain. PSNR was better for some clips, and worse for others. Overall it was even. Change-Id: If787a57bedf46fc595ca4f5ded2b0c0a69e9fdef
2013-09-10Merge "Modify encode breakout for static frames"Yunqing Wang
2013-09-10Modify encode breakout for static framesYunqing Wang
Thank Paul for the suggestions. While turning on static-thresh for static-image videos, a big jump on bitrate was seen. In this patch, we detected static frames in the video using first-pass stats. For different cases, disable encode breakout or reduce encode breakout threshold to limit the skipping. More modification need be done to break incorrect partition picking pattern for static frames while skipping happens. Change-Id: Ia25f47041af0f04e229c70a0185e12b0ffa6047f

2013-09-10Modified mode skip functionality.Paul Wilkins
A previous speed feature skipped modes not used in earlier partitions but this not longer worked as intended following changes to the partition coding order and in conjunction with some other speed features (Especially speed 2 and above). This modified mode skip feature sets a mask after the first X modes have been tested in each partition depending on the reference frame of the current best case. This patch also makes some changes to the order modes are tested to fit better with this skip functionality. Initial testing suggests speed and rd hit count improvements of up to 20% at speed 1. Quality results. (derf -1.9%, std hd +0.23%). Change-Id: Idd8efa656cbc0c28f06d09690984c1f18b1115e1

The commit changes the border pixel extension from 160 pixel each side to what is necessary in arnr filter or motion estimation portion, i.e. 16 pixel on top and left side. For right or bottom side, the extension is changed to either round up image size to multiple of 64 or at least 16 pixels. Change-Id: Ic05e19b94368c1ab4df568723aae5734e6c3d2c5

2013-09-06Fix overflow issue in 16x16 quantization SSSE3Jingning Han
The 16x16 transform unit test suggested that the peak coefficient value can reach 32639. This could cause potential overflow issue in the SSSE3 implmentation of 16x16 block quantization. This commit fixes this issue by replacing addition with saturated addition. Change-Id: I6d5bb7c5faad4a927be53292324bd2728690717e

2013-09-06Support a constant quality mode in VP9Deb Mukherjee
Adds a new end-usage option for constant quality encoding in vpx. This first version implemented for VP9, encodes all regular inter frames using the quality specified in the --cq-level= option, while encoding all key frames and golden/altref frames at a quality better than that. The current performance on derfraw300 is +0.910% up from bitrate control, but achieved without multiple recode loops per frame. The decision for qp for each altref/golden/key frame will be improved in subsequent patches based on better use of stats from the first pass. Further, the qp for regular inter frames may also be varied around the provided cq-level. Change-Id: I6c4a2a68563679d60e0616ebcb11698578615fb3

2013-09-06New mode_info_context storageScott LaVarnway
mode_info_context was stored as a grid of MODE_INFO structs. The grid now constists of a pointer to a MODE_INFO struct and a "in the image" flag. The MODE_INFO structs are now stored as a stream, eliminating unnecessary copies and is a little more cache friendly. For the test clips used, the decoder performance improved by ~4.3% (1080p) and ~9.7% (720p). Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p) and 5.9% (720p).
