Ari Koivula fb763f7940 Move coefficient generation functions from encoder.c to transform.c. 
- These functions probably should have been there to begin with.
 2014-05-12 11:37:39 +03:00
Ari Koivula a3478ecd20 Move transform skip decision to it's own function. 2014-05-12 11:18:27 +03:00
Ari Koivula d9b890de6e Remove redundant variables. 
- Redefine LCU_WIDTH to be 64. Stuff will break horribly if it's
  anything else anyway.

- Add LCU_WIDTH_C for chroma LCU width. It should be more readable than the
  constant (LCU_WIDTH >> 1).

Ari Koivula 59e0e98523 Separate luma and chroma coefficient generation variables. 2014-05-12 10:38:24 +03:00
Ari Koivula 0ca65e7606 Move chroma coefficient generation to it's own function. 
- It's time to chop up this monster that is encode_transform_tree.

Ari Koivula 3c3c9a26c6 Move scan order selection to a function. 2014-05-12 08:47:16 +03:00
Ari Koivula 623d9001a8 Reorder chroma coefficient generation. 2014-05-12 08:47:16 +03:00
Ari Koivula 93141c7d2e Avoid unnecessary copying of predicted pixels when there are no coeffs. 
- These are probably from a time when reconstruction happened in this
  function.

Ari Koivula 27ab882c25 Clean up coefficient generation. 2014-05-09 16:33:10 +03:00
Ari Koivula ce945ab4ef Handle coefficient initialization better. 
- Coefficients are no longer required to be pre-zeroed. The resulting zeroes
  are copied in even in the case where we already know they are all zeroes.

- Move cbf clearing code to only happen at the leaves of the recursion.

Laurent Fasnacht b48a687d3c Restored parallelism, but it will be done in another way... OpenMP is not very efficient in these kind of dynamic situation 2014-05-07 11:55:56 +02:00
Laurent Fasnacht 0e6f1c99fc Refactor picture to remove hidden dependency between slice and tiles 
picture.type -> encoder_state->global->pictype
picture.slicetype -> encoder_state->global->slicetype
picture.slice_sao_luma_flag -> 1 (was constant)
picture.slice_sao_chroma_flag -> 1 (was constant)

This may be changed later. For now it's better to avoid having slice related stuff in picture.

Ari Koivula eaf8835bda Add some comments and const qualifiers. 2014-05-06 19:20:38 +03:00
Ari Koivula 3910b7989a Clear old cbf data before recursion in encode_transform_tree. 
- Because encode_transform_tree also maintains the CBF data and assumes that
  the CBFs are initially zeroed, calling the function more than once would
  result in incorrect CBF data.
 2014-05-06 19:03:29 +03:00
Ari Koivula bdc16d2612 Improve cu_info coded block flag data structure a bit. 
- It works just like the old structure except that the flags are checked with
  bitmasks instead of having the flag value be propagated upwards. There isn't
  really any benefit to this because the flags still have to be propagated to
  parent CUs.

- Wrapped them inside a struct to make copying them easier. (Just need to copy
  the struct instead of making individual copies)
 2014-05-06 18:28:04 +03:00
Ari Koivula d123b98aea Remove unnecessary tertiary expressions from usages of CABAC_BIN. 2014-05-06 17:39:25 +03:00
