2013-09-11New mode_info_context storage -- undo revertScott LaVarnway
mode_info_context was stored as a grid of MODE_INFO structs. The grid now constists of pointers to MODE_INFO structs. The MODE_INFO structs are now stored as a stream (decoder only), eliminating unnecessary copies and is a little more cache friendly. Change-Id: I031d376284c6eb98a38ad5595b797f048a6cfc0d
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
2013-09-10Modify 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

2013-09-08Reduce the amount of extension in src framesYaowu Xu
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).

2013-09-05Use saturated addition in SSSE3 of 32x32 quantJingning Han
The 32x32 forward transform can potentially reach peak coefficient value close to 32700, while the rounding factor can go upto 610. This could cause overflow issue in the SSSE3 implementation of 32x32 quantization process. This commit resolves this issue by replacing the addition operations with saturated addition operations in 32x32 block quantization. Change-Id: Id6b98996458e16c5b6241338ca113c332bef6e70
