2013-05-16Removed Q threshold in the usage of ADSTYaowu Xu
Test on cif set showed small but consistent compression gain for almost all encodings with overall impact of .08%. The gains average aournd .12% combined with D63 adst change. Test encoding on std-hd set is ongoing.. Change-Id: If4d94799cf0486fb9c770b193e5c386d13d99d59

2013-05-15Combining integer and fractional parts of mvs for entropy coding.Dmitry Kovalev
Combining encode_nmv_component with encode_nmv_component_fp and read_nmv_component with read_nmv_component_fp. Bitstream is slightly changed (only the order of bits), here are the results on test sets: stdhd: +0.047, yt: -0.038, derf: +0.001, hd: -0.011. Change-Id: I1be312e976796df78ca63368702d0ee19f2b8c50
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

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
