2014-02-25Use sub-pixel accuracy prediction non-RD modeJingning Han
This commit builds the actual prediction block in sub-pixel accuracy and uses which to calculate SAD for non-RD mode decision. In the trail run on pedestrian_area at 1080p, rtc speed -7 runtime goes from 23495 ms -> 25107 ms (7% slower). The compression performance is improved by 20.57% for rtc test set.

2014-02-25Use dedicated variables to store the best modeJingning Han
Use a set of dedicated variables to buffer the current best mode in non-RD mode decision. This allows to use mode_info for more complicated test in the non-RD process. Change-Id: I6024c9feb0662afd3eb29f7017f7b5a5446f303f

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
2014-02-20Enable reduced set of intra modes in rtc codingJingning Han
This commit enables the use of DC, vertical, and horizontal intra prediction mode in rtc non-RD mode decision. When the best cost value of inter modes is above a given threshold, the encoder runs the above three intra modes and selects the one that has minimum prediction residual in terms of SAD. This together with recent changes on non-RD mode decision and coding control improves compression performance of speed -6 by derf 91% yt 61% hd 46% stdhd 52% In terms of encoding speed, it is about 3 times faster than speed -5.

2014-02-19Rework non-RD mode decision coding flowJingning Han
In the first coding run of a 64x64 block, check the coding mode for each 8x8 block. Will need a second annealing stage to decide the partition size to be encoded. Change-Id: Ida9417805ff3358979b0c0429d4099c023c88866

2014-02-18Enable sub-pixel motion search for rtc modeJingning Han
Run sub-pixel motion search when NEWMV gives lower rate-distortion cost. This improves coding performance of derf set by 8%, std-hd by 2.2%. Change-Id: Ife50f7fda8463927784fe59a41cc439c833e941a

2014-01-29create super fast rtc modeJim Bankoski
This patch only works if the video is a width and height that are both a multiple of 32.. It sets every partition to 16x16, and does INTRADC only on the first frame and ZEROMV on every other frame. It always does does the largest possible transform, and loop filter level is set to 4. Was ~20% faster than speed -5 of vp8 Now 20% slower but adds motion search ( every block ), nearest, near and zeromv The SVC test was changed because - while this realtime mode produces bad quality albeit quickly, it isn't obeying all the rules it should about which frames are available.
