2013-05-14WIP: 32x32 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: I4ea09df0e162591e420d869b7431c2e7f89a8c1a
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

2013-05-10Enable recursive partition type searchJingning Han
This commit enables the search for the optimal superblock partition types in the recursion form. The intention is to make the optimization process more concise and ready to support partition down to 4x4 block size next. Change-Id: Iae279a67df3a7cc372553c84c775bc4d2f3e4336

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

2013-05-08Extend left/above partition context to per mi(8x8)Jingning Han
Update and buffer left/above partition information context per 8x8 block. This allows to further enable recursive partition down to 4x4 block size, and hence deprecating I4X4_PRED and SPLITMV. This commit also fixes a context buffer swap/restore issue in 32x32 partition type search. This gives 0.1% performance gain for derf/yt. Will refactor the superblock partition type search into recursion form. Change-Id: Ib61975aca5f12b78d8018481d7fa1393d085689b
