2014-02-25Adds variance based fixed size partitioningDeb Mukherjee
Adds a method for determining a fixed size partition based on variance of a 64x64 SB. This method is added to rtc speed 6. Also fixes a bug in rtc_use_partition() and includes some refactoring related to partitioning search, and some cosmetics. Currently compared to speed 5, the coding efficiency of speed 6 is -19% and that of speed 7 is -55%, in cbr mode. Change-Id: I057e04125a8b765906bb7d4bf7a36d1e575de7c6

The optimizer did something funny with the code around line 1412. Before the call to encode_sb split_dist was set properly but after it was adjusted and converted to a negative. https://code.google.com/p/webm/issues/detail?id=714 Change-Id: I9a7631d5325ade2dc28c1030653a23eecec8721b

2014-02-24Adds an intermediate speed level for rtcDeb Mukherjee
Moves the existing speed 6 to speed 7 and adds an intermediate level 6 which is roughly in between speeds 6 and 7 in both speed and coding efficiency. Also includes some minor fixes/adjustments. Change-Id: I98befc4d82d750e79fe426c457c4a2571f6b6cc7

2014-02-21Refactor selected partition size coding for rtcJingning Han
This commit makes a refactoring of the rtc_use_partition. It allows the encoder to take a preferred block size for non-RD mode decision. The boundary blocks are handled such that smaller block sizes that fit in the boundary size will be used instread. In rtc mode, the coding performance of speed -6 for pedestrian_1080p goes from 158980 b/f, 38.934 dB, 22721 ms to 159008 b/f, 40.064 dB, 23721 ms. For rtc set, the speed -6 compression performance is improved by 26%. Still about 2dB behind speed -5 at this point. Change-Id: If0944f0880eaf1ad340bc325d97cea8d0f9dd53f

2014-02-13Removed the reset of mode_info from previous frameYaowu Xu
Prior to this commit, both encoder and decoder reset mode/mv info from previous frame in error resilient mode to ensure bitstreams are able to decode when there is loss of frame in decoder side. However, this is not necessary. This commit changed to remove the reset, so encoder can continue to use mode/mv/partition information from previously encoded frame without affecting decodeablilty under loss of frame.

In rtc coding mode, the encoder is running non-RD mode decision. It does not need dual buffer swap as was the case in the RD mode. This commit initializes the internal buffer pointers outside the block coding loop for rtc mode. Change-Id: Ie076705c60d6b7919217e3f1dfd49e7db5064ac2

2014-02-11Enable encode_breakout in real time encodingYunqing Wang
In real time encoding, we enable encode_breakout to make encoding fast. A speed feature "use_encode_breakout" is defined to set encode_breakout thresholds for different speeds. However, currently, static_thresh is an encoder option. The encode_ breakout can be turned off if user sets static_thresh=0 specifically. The rtc set borg test result: (need to set --static_thresh=1) speed -5, psnr loss -3.543%; speed -4, psnr loss -2.358%; speed -3, psnr loss -0.771%. Encoding speed test: speed -5, 11% - 60% speedup; speed -4, 5.5% - 28% speedup; speed -3, 0.8% - 7% speedup. Change-Id: Icde592ffbe77eac7446f872a2e9eb2051733677b

2014-02-11Modified Aq1 and Aq2Paul Wilkins
Aq 1 only updates segment map on kf and arf and only uses 3 segments. With these settings AQ1 is + for most clips in SSIM but negative in psnr. However, the penalty in PSNR is much less than previously. Old version aq1 average results for std hd -20.899% psnr, -5.809% SSIM New version aq1 for std hd -3.57% psnr, +1.23% SSIM Aq2 Now uses only 2 segments and rd. This mode is still slightly negative for most clips on psnr and SSIM but seems to have a much bigger visual impact on several problem clips than aq mode 1. Old results for std hd: -2.578% psnr, -1.151% SSIM New results for std hd: -1.561% psnr, -0.85% SSIM Change-Id: I94f57f8a73121629ce598fb921aad761c1450e1c
