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

2013-05-14Enable 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

2013-05-13Change 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

2013-05-10Add 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. Change-Id: I3211cee5ccf1cfb426e5eef5353b0ce5bb92b4cd
2013-05-09Subsampling aware allocs and bitstreamJohn Koleszar
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
