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.

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.

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.

Ari Koivula 0fd9105f0a Fix sao type context init values.
The initialization slice types are in reverse order compared to the codes used
for slice types. They are BPI instead of IPB.

Ari Koivula 3244c98b29 Fix sao cabac contexts.
According to HM implementation, sao luma and chroma use the same contexts.

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.

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.

Ari Koivula d74d4e4ef1 Refactor intra sad calculation functions.
- Move SATD (hadamart) code to it's own functions.
- Generate functions for fixed block sizes with macros, as if using templates.
- Define new interface with function pointer cost_16bit_nxn_func that different
  cost functions can use.
- Hide fixed size block cost functions with getters.
