Refactor: Fix include guards. - Remove _ from the beginning of include guards because that prefix is for the implementation. - Move include guards to the beginning of file. - Unify the syntax.

Update Doxygen documentation Add module information to all header files. Update all header file documentations to briefly say what they are, and to use the javadoc format so the brief actually gets included into the doxygen documentation. Remove \file from implementation files, in order to not repeat the info from the header files. Add files under strategies and tools to Doxygen and update the Doxygen settings to be just plain better. Make README be the main page of Doxygen documentation.

Run include-what-you-use fix_includes.py fix_includes.py The includes should make more sense now and not just happen to compile due to headers included from other headers. Used a modified version of IWYU. Modifications were to attribute int8_t and so on to stdint.h instead of sys/types.h and immintrin.h instead of more specific headers. include-what-you-use 0.7 (git:b70df35) based on clang version 3.9.0 (trunk 264728)

#include "cu.h"
Reorder includes to avoid hidden dependencies. - Includes of global.h have been moved to headers because most headers require stdint.h. - Includes required by the header have been moved from the .c to the header. - Spaces have been added between includes to distinguish classes of includes.

Add extern for g_chroma_scale. - g_chroma_scale is used in filter.c.

void kvz_itransformskip(const encoder_control_t *encoder, int16_t *block,int16_t *coeff, int8_t block_size);
Implemented transform skipping (for 4x4 blocks) transform skip vs. normal transform selection criteria might need more work, currently both are calculated for each 4x4 block and SAD+coeff_SSE is compared.
2014-04-02 07:54:03 +00:00
Fix selection of transform function for 4x4 blocks DST function was returned for inter luma transform blocks of size 4x4 even though they must use DCT. Fixed by checking the prediction mode of the block in addition to whether it is chroma or luma.

[jccr] WIP initial implementation Add somekind of search for joint chroma residual coding. Bitstream is currently correct but prediction is incorrect because the jccr is actually not used in the search. Hard coded to be enabled

Combine luma and chroma quantization functions Replaces functions kvz_quantize_lcu_luma_residual and kvz_quantize_lcu_chroma_residual in transform.c with function kvz_quantize_lcu_residual. The new function can handle any of the YUV colors. Removes some duplicated code.
