2013-05-15WIP: 16x16 idct/recon mergeScott LaVarnway
This patch eliminates the intermediate diff buffer usage by combining the short idct and the add residual into one function. The encoder can use the same code as well. Change-Id: Iea7976b22b1927d24b8004d2a3fddae7ecca3ba1

2013-05-14Enable recursive partition down to 4x4Jingning Han
This commit allows the rate-distortion optimization recursion at encoder to go down to 4x4 block size. It deprecates the use of I4X4_PRED and SPLITMV syntax elements from bit-stream writing/reading. Will remove the unused probability models in the next patch. The partition type search and bit-stream are now capable of supporting the rectangular partition of 8x8 block, i.e., 8x4 and 4x8. Need to revise the rate-distortion parts to get these two partition tested in the rd loop. Change-Id: I0dfe3b90a1507ad6138db10cc58e6e237a06a9d6

2013-05-13Do joint motion search iterativelyYunqing Wang
Allow motion search multiple times iteratively, and break out the loop if this search couldn't find better motion vectors. Limit the maximum number of search to 2. Tests results: 1. stdhd set: 0.311%(overall psnr); 0.346%(ssim). positive gain on 10 out of 16 clips(best: 2.746% on sunflower; worst: -0.434% on old_town_cross). 2. derf set: 0.016%(overall psnr); 0.062%(ssim). positive gain on half of the clips(best: 0.499% on bowing; worst: -0.387 on city).

2013-05-13Change to band calculation.Paul Wilkins
Change band calculation back to simpler model based on the order in which coefficients are coded in scan order not the absolute coefficient positions. With the scatter scan experiment enabled the results were appear broadly neutral on derf (-0.028) but up a little on std-hd +0.134). Without the scatterscan experiment on the results were up derf as well. Change-Id: Ie9ef03ce42a6b24b849a4bebe950d4a5dffa6791
2013-05-11Use consistent partition context setup in enc/decJingning Han
Move set_partition_seg_context_ to common file. Use consistent context setup conditions for partition probability model update at encoder and decoder. Change-Id: I24b7ed3b1c48e3d2568191a46b70136b99b67b1a
2013-05-11Force bsize for UV in I4X4 and SPLITMVJingning Han
Use 4x4 block coding for UV components arbitrarily in I4X4_PRED and SPLITMV coding modes. This is a temporary solution to enable bit-stream support for recursive partition down to 4x4 block size. Will separate the functionalities of 4x4 block coding rate-distortion out from those of superblocks. Change-Id: I03dc15d5897014f175f3f2c91e9b266091d56797

2013-05-10Add joint motion search in comp_inter_inter mode(experiment)Yunqing Wang
In current code, motion vectors got from single prediction mode are used in compound prediction mode directly. These motion vectors may not give accurate prediction since they are searched independently. In this patch, we took Pascal's suggestion, and did joint motion search in compound prediction mode to find better motion vectors in this situation. Test results: Overall PSNR: 0.570%(derf), 0.918%(stdhd); SSIM: 0.572%(derf), 1.009%(stdhd); The encoder is a little slower. This can be improved since some c code is used in motion search.

2013-05-09Fix non-4:2:0 chroma MV calculation for SPLITMVJohn Koleszar
The previous code was somewhat vestigial for 16x16 MI units, but was incorrect when called with chroma blocks larger than 4x4 because the block index caused a reference to a non-existent BMI. This patch uses the same MV for all chroma subblocks in SPLITMV mode, which is suboptimal for non-4:2:0 subsamplings, but as SPLITMV may be removed in the near future, will use this as a stop gap.

Make framebuffer allocations according to the chroma subsamping factors in use. A bit is placed in the raw part of the frame header for each of the two subsampling factors. This will be moved in a future commit to make them part of the TBD feature set bits, probably only set on keyframes, etc. Change-Id: I59ed38d3a3c0d4af3c7c277617de28d04a001853
