Ari Koivula 77339efa57 Add COPYING file and add boilerplate for copyright and GPLv2 to every file. 2014-01-24 12:48:48 +02:00
Ari Koivula f1d8aae5b4 Clean up SAO encoding. 
- Fixes a bug when pic->slice_sao_chroma == false.
 2013-12-19 13:54:32 +02:00
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 692ef3e9d9 Add guard against illegal SAO edge offsets. 2013-11-08 16:13:48 +02:00
Ari Koivula 43ae719ddb Tweak implementation of SAO reconstruction to be a bit more clear. 2013-11-08 15:04:06 +02:00
Ari Koivula f9061d322a Fix handling of incomplete LCU's in SAO reconstruction. 2013-11-06 23:09:56 +02:00
Ari Koivula 7a20e797be Fix incorrect SAO encoding. 2013-11-06 22:50:26 +02:00
Ari Koivula 3eccdc0d7b Move deblocking filtering to happen before SAO reconstruction. 
-Re-enable deblocking.
 2013-11-06 22:50:14 +02:00
Ari Koivula 98f2a1aedc Fix LCU borders in sao reconstruction. 2013-11-06 11:23:01 +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.

 2013-11-04 12:44:01 +02:00
