Ari Koivula 0c65a9b658 Remove abs_sum from coeff quantization. 
- It's meant for checking if there are any coefficients, but we don't use it
  and it's annoying to remember to initialize it and pass it around. The
  benefit should be quite small anyway.
 2014-05-13 21:54:34 +03:00
Ari Koivula 75042fc65d Move luma quantization to it's own function. 2014-05-13 21:34:06 +03:00
Ari Koivula ba3aaf3189 Expand chroma functions to parent function. 
- This was done so that making the function work with luma would be easier.
 2014-05-13 21:30:14 +03:00
Ari Koivula 637aceb495 Add TR_MAX_WIDTH. 
- Max transform size is constrained by but independent of LCU size.

- Luma and chroma now have the same stride for transform arrays.

Ari Koivula 1c38209cab Add missing include. 2014-05-13 09:33:05 +03:00
Ari Koivula 13577562e5 Revert change to definition of LCU_WIDTH. 2014-05-13 09:28:01 +03:00
Ari Koivula 6b27d67b46 Merge branch 'coeff_cleanup' 2014-05-12 15:37:03 +03:00
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).
 2014-05-12 10:58:07 +03:00
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.
 2014-05-12 10:24:06 +03:00
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.
 2014-05-09 16:39:58 +03:00
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 43b5f84c0d Fix sao_calc_edge_block_dims

Ari Koivula f890ffb1e5 Update SConstruct to work with mingw64. 
- 64bit mingw64 needs TMP.

- Also add openmp and -march=native, as those are also in the makefile.

- Might help with #54.

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.
