2015-02-19Improve skip_txfm thresholds in the non-rd mode selectionYunqing Wang
Modified the thresholds of deciding whether or not to skip the transforms in model_rd_for_sb_y(). Used zbin[] instead of dequant[] to be more precise. Also, modified the checking coditions. Rtc set borg test results (at speed 6) showed: average PSNR gain: 0.138%, overall PSNR gain: 0.158%, and SSIM gain: 0.177%. The data rate test was modified slightly as suggested by Marco.

2015-02-19Integral projection based motion estimationJingning Han
This commit introduces a new block match motion estimation using integral projection measurement. The 2-D block and the nearby region is projected onto the horizontal and vertical 1-D vectors, respectively. It then runs vector match, instead of block match, over the two separate 1-D vectors to locate the motion compensated reference block. This process is run per 64x64 block to align the reference before choosing partitioning in speed 6. The overall CPU cycle cost due to this additional 64x64 block match (SSE2 version) takes around 2% at low bit-rate rtc speed 6. When strong motion activities exist in the video sequence, it substantially improves the partition selection accuracy, thereby achieving better compression performance and lower CPU cycles. The experiments were tested in RTC speed -6 setting: cloud 1080p 500 kbps 17006 b/f, 37.086 dB, 5386 ms -> 16669 b/f, 37.970 dB, 5085 ms (>0.9dB gain and 6% faster) pedestrian_area 1080p 500 kbps 53537 b/f, 36.771 dB, 18706 ms -> 51897 b/f, 36.792 dB, 18585 ms (4% bit-rate savings) blue_sky 1080p 500 kbps 70214 b/f, 33.600 dB, 13979 ms -> 53885 b/f, 33.645 dB, 10878 ms (30% bit-rate savings, 25% faster) jimred 400 kbps 13380 b/f, 36.014 dB, 5723 ms -> 13377 b/f, 36.087 dB, 5831 ms (2% bit-rate savings, 2% slower) Change-Id: Iffdb6ea5b16b77016bfa3dd3904d284168ae649c

2015-02-17Fix the frame parallel invalid file test failure on ARM.hkuang
There is a corner case that when a frame is corrupted, the following inter frame decode worker will miss the previous failure. To solve this problem, a need_resync flag needs to be added to master thread to keep control of that. Change-Id: Iea9309b2562e7b59a83dd6b720607410286c90a6

2015-02-13Fix an encoder/decode mismatch bugYaowu Xu
This commit prevent the encoder to update last_frame_type when a frame is dropped in the encoder. Prior to this fix, if there is a dropped frame immediatedly after a key frame, decoder would have the value of last_frame_type as key frame, different from encoder as the dropped frame in encoder would have updated the value to an inter frame. This leads to different probability update in encoder and decoder, thereby encoder/decoder mismatch. This fixes issue #941 Change-Id: I27115224b138bec43ae3916c016574f5740822b0

2015-02-10Auto-adaptive encoder frame resizing logicAdrian Grange
Note: This feature is still in development. Add an option for the encoder to decide the resolution at which to encode each frame. Each KF/GF/ARF goup is tested to see if it would be better encoded at a lower resolution. At present, each KF/GF/ARF is coded first at full-size and if the coded size exceeds a threshold (twice target data rate) at the maximum active Q then the entire group is encoded at lower resolution. This feature is enabled in vpxenc by setting: --resize-allowed=1 In addition, if the vpxenc command line also specifies valid frame dimensions using: --resize-width=XXXX & --resize_height=YYYY then *all* frames will be encoded at this resolution.
