2013-06-18Make fdct32 computation flow within 16bit rangeJingning Han
This commit makes use of dual fdct32x32 versions for rate-distortion optimization loop and encoding process, respectively. The one for rd loop requires only 16 bits precision for intermediate steps. The original fdct32x32 that allows higher intermediate precision (18 bits) was retained for the encoding process only. This allows speed-up for fdct32x32 in the rd loop. No performance loss observed.

Don't do the 15 tap filter if there aren't 8 pixels below/right of the edge. Change-Id: I62f16437c1d9ba59b6901a5fe71ddb2f472da344
2013-06-10Fix partition coding of corner blockJingning Han
This commit fixed the allowable partition types for bottom-right corner blocks. When a block has over half of its pixels as valid content in both vertical and horizontal directions, allow all the four partition types in the bit-stream. Otherwise, apply partition type constraints. Change-Id: I2252e2de7125a8bfb1c824bf34299a13c81102e3

2013-06-10Cosmetic cleanups of filtersDeb Mukherjee
No bitstream change. Removes unused filters and the code for the case of 2 switchable filters; also changes the 8tap-smooth filter coefficients for integer shifts to be interpolating to be consistent with the way it is implemented currently. Change-Id: I96c542fd8c06f4e0df507a645976f58e6de92aae

2013-06-10Merge "Loopfilter: bug fix in sb_type usage" into experimentalYaowu Xu
2013-06-10Fixed point reference picture scalingTero Rintaluoma
Fixed point scaling factors are calculated once for each reference frame by using integer division. Otherwise fixed point scaling routines are used in all scaling calculations. This makes it possible to calculate fixed point scaling factors on device driver software and pass them to hardware and thus avoid division on hardware. TODO: - Missing check for maximum frame dimensions (currently scaling uses 14 bits) - Missing check for maximum scaling ratio (upscaling 16:1, downscaling 2:1) Problems: - Straightforward fixed point implementation can cause error +-1 compared to integer division (i.e. in x_step_q4). Should only be an issue for frames larger than 16k. Change-Id: I3cf4dabd610a4dc18da3bdb31ae244ebaf5d579c

2013-06-07Handle partition type coding of boundary blocksJingning Han
The partition types of blocks sitting on the frame boundary are constrained by the block size and the position of each sub-block relative to the frame. Hence we use truncated probability models to handle the coding of such information. 100 frames run: yt 0.138% Change-Id: I85d9b45665c15280069c0234ea6f778af586d87d

2013-06-07Don't crash if motion vector ref points to out-of-bounds area.Ronald S. Bultje
This can only happen if partition is partly out-of-frame, in which case the referenced mv is either out-of-frame also (and thus has the same value as an already-read one), or it is actually uninitialized, in which case we don't want to use it. Change-Id: Icf39fa4d987c7abcbebb9bbdcdd6311e8fb9d3c9
