Ari Koivula 3af65b8477 Add SAO searching and reconstruction for chroma. 
One I frame and 99 P frames encoded with SAO off and on.
Processed 100 frames,    6693224 bits AVG PSNR: 30.7248 37.8978 37.8287

Ari Koivula 22d21ffac2 Enable SAO search. 
-Add guard to reconstruction to avoid reconstructing LCUs with no sao type.

Ari Koivula 5791301c2b Fix moving of rightmost LCUs during sao reconstruction. 
Now the leftmost LCUs move though.
 2013-11-04 21:37:04 +02:00
Ari Koivula 91024a2095 Disable deblocking because it breaks sao. 2013-11-04 20:51:51 +02:00
Ari Koivula 5f3ee9e096 Sao vcxproj files. 2013-11-04 20:35:48 +02:00
Ari Koivula f21df00386 Save a copy of luma for sao. 2013-11-04 20:33:29 +02:00
Ari Koivula a57b938270 Add new module sao. 
- Move sao-stuff not directly related to encoding to sao-module.
- Calculate sao for all LCUs before encoding any of them. This is in
  preparation to doing the reconstruction line at a time instead of
  LCU at a time.
 2013-11-04 19:41:01 +02:00
Ari Koivula 03f2967899 Block based sao dead end. 
This will never work because the adjacent blocks require the original values
of the boundary pixels to make category decisions.
 2013-11-04 17:55:29 +02:00
Ari Koivula 31af7e3929 Fix sao offsets. Reconstruction kind of works. 2013-11-04 13:05:05 +02:00
Ari Koivula 66fe302520 Fix cabac context for sao. HM accepts encoded sao. 2013-11-04 13:03:51 +02:00
Ari Koivula b6c5c87fb7 Merge branch 'master' into sao 
SAO needs to be coded before LCU data has been searched. Searching
has already been moved to happen before encoding in the master branch.

Conflicts:
	src/encoder.c
	src/picture.c
	src/picture.h
 2013-11-04 12:44:01 +02:00

The initialization slice types are in reverse order compared to the codes used
for slice types. They are BPI instead of IPB.
 2013-10-25 10:51:11 +03:00
Ari Koivula 3244c98b29 Fix sao cabac contexts. 
According to HM implementation, sao luma and chroma use the same contexts.

Marko Viitanen bcb900371f Added top_coeff array to cu_info and implemented derivation logic 2013-10-22 12:09:18 +03:00
Ari Koivula c0f06fdb9e Change intra prediction to use SAD instead of SATD. 
Inter uses only SAD and we don't have mechanisms for comparing these two.
 2013-10-21 17:42:55 +03:00
Ari Koivula 27f5555b1c Change hexacon_search to take const pointers. 2013-10-18 17:51:53 +03:00

Ari Koivula c7ca3a6b44 Clarify parameter passing for hexagon_search. 
Handling mv as a local struct instead of pointer had no performance impact,
but it makes the parameter passing clearer so I'm keeping it.
