Ari Koivula 84cd618daf Add calculation of SAO-offsets for non-LCU sized CUs. Luma SAO works now. 2013-11-11 09:49:49 +02:00
Ari Koivula 692ef3e9d9 Add guard against illegal SAO edge offsets. 2013-11-08 16:13:48 +02:00
Ari Koivula 22d21ffac2 Enable SAO search. 
-Add guard to reconstruction to avoid reconstructing LCUs with no sao type.
-Add temporary guard to SAO search to skip LCUs can't be handled yet.

Ari Koivula 8b0eb66555 Fix bug in SAO reconstruction. 2013-11-08 15:04:53 +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 ef8a984d4f Fix incorrect blitting of top row during SAO reconstruction. 2013-11-08 11:02:18 +02:00
Ari Koivula f9061d322a Fix handling of incomplete LCU's in SAO reconstruction. 2013-11-06 23:09:56 +02:00
Ari Koivula 1c03471d57 Fix for leftmost LCUs being offset by one pixel during SAO reconstruction. 2013-11-06 22:26:00 +02:00
Ari Koivula 98f2a1aedc Fix LCU borders in sao reconstruction. 2013-11-06 11:23:01 +02:00
Ari Koivula 5791301c2b Fix moving of rightmost LCUs during sao reconstruction. 
Now the leftmost LCUs move though.

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.
