Marko Viitanen 40138f082e Modified intra_get_dir_luma_predictor() to use the new structure 
Also fixed intra_pred_ratecost() parameters and usage of intra_build_reference_border()
 2014-02-26 12:38:30 +02:00
Marko Viitanen 1197e24b3f Modified intra_prediction() to use new structure and renamed intra_merge_cost() 2014-02-26 12:34:22 +02:00
Marko Viitanen 68b4e9e3db Modified intra_build_reference_border() to work on the new structure 2014-02-26 12:30:12 +02:00
Marko Viitanen d0a9c5e83b Implemented intra_recon_lcu() to reconstruct intra in the new structure 2014-02-26 12:28:24 +02:00
Marko Viitanen fb9e3ad1d2 Implemented proper intra mode cost calculation 
This does not currently affect the search primary search defining the used block sizes, only the refining second intra search. Gain 1.9% BD-rate on All Intra 600f of BQMall QP 22,27,32,37.

Ari Koivula b067b2f802 Add lcu_t initialization. 2014-02-26 10:58:20 +02:00
Ari Koivula 7e520a85c4 Add skeleton/plan for LCU based search. 
The plan is to replace the dumb search we are doing now with proper sequential
search that is encapsulated inside data structure that holds all temporary
search data for the LCU.

Luca Barbato a6dfe79d16 encoder: Export g_convert_to_bit correctly 
It is a global table initialized in encoder.c and used all over the
codebase.

Ari Koivula db4402e8d6 Fix for SAO band offset merge cost calculation. 
Gives a tiny improvement to both bit rate and psnr.
 2014-02-22 16:08:39 +02:00
Marko Viitanen 34f558ddd7 Fixed SAO cost checking, disabling SAO when RD-cost is 0 
Decreases overall BD-rate a bit more, this fix prevents coding zero offsets to the bitstream

Ari Koivula 73f5c3b80e Fix compiler warnings for VS2010 /W4 in config.c and encmain.c. 
- Working towards issue #11.
- Widened datatypes for cfg struct members that take values from atoi to full
  ints so that bounds checking can be done after parsing without overflow.

Ari Koivula db3b96b90b Fix compiler warnings for VS2010 /W4 in bitstream.c and cabac.c. 
- Working towards issue #11.

Ari Koivula 5760c79272 Fix crash with dimensions that are not multiples of 8. 
The clean up of input parsing and encoder initialization code had caused the
real source input dimensions to be used for array initialization, instead of
the dimensions modified to be multiples of the smallest coding unit.

 2014-02-20 11:09:09 +02:00
Ari Koivula 18c3d9c72d Add scons build script. 
We will also maintain the Makefile for basic building. This is for more
complicated stuff, like building the project on command line with
Visual Studio.
