General cleanups. Removing unused constants, macros, and function declarations. Using ROUND_POWER_OF_TWO macro, vp9_zero, vp9_copy where possible. Moving #include from .h to .c. Merging for loops for motion vectors. Change-Id: Ic3bf841764a2bb177128bb3a6d7aa8f68229cd13 2013-07-25 23:13:44 +02:00			`#include "vp9/decoder/vp9_dboolhuff.h"`

Renaming BLOCK_SIZE_TYPE to BLOCK_SIZE in the common/decoder. Adding temporary "typedef BLOCK_SIZE BLOCK_SIZE_TYPE" which will go away after encoder's patch.

Make superblocks independent of macroblock code and data. Split macroblock and superblock tokenization and detokenization functions and coefficient-related data structs so that the bitstream layout and related code of superblock coefficients looks less like it's a hack to fit macroblocks in superblocks. In addition, unify chroma transform size selection from luma transform size (i.e. always use the same size, as long as it fits the predictor); in practice, this means 32x32 and 64x64 superblocks using the 16x16 luma transform will now use the 16x16 (instead of the 8x8) chroma transform, and 64x64 superblocks using the 32x32 luma transform will now use the 32x32 (instead of the 16x16) chroma transform. Lastly, add a trellis optimize function for 32x32 transform blocks. HD gains about 0.3%, STDHD about 0.15% and derf about 0.1%. There's a few negative points here and there that I might want to analyze a little closer. Change-Id: Ibad7c3ddfe1acfc52771dfc27c03e9783e054430 2013-03-04 23:12:17 +01:00
Use standard integer types for pixel values and coefficients. For coefficients, use int16_t (instead of short); for pixel values in 16-bit intermediates, use uint16_t (instead of unsigned short); for all others, use uint8_t (instead of unsigned char).
