Ari Koivula 13577562e5 Revert change to definition of LCU_WIDTH. 2014-05-13 09:28:01 +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 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.

Laurent Fasnacht f30b9c2a11 Fix a buffer overflow in parse_tiles_specification 2014-05-07 11:39:45 +02:00
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
Ari Koivula 380401b2eb Have CABAC_BIN accept any >0 as binary 1. 
It used to treat odd numbers as false.

Ari Koivula 42295d3cb9 Pass preprocessor defines for supported intrinsics in VS2010 explicitly. 
- _M_IX86_FP defines whether VS should generate code using SSE or SSE2
  instructions. It isn't correct to use it to check whether optional runtime
  optimizations should be compiled in. It's also not defined at all in 64-bit
  mode.

- So let's just keep it simple and give a list of everything that is supported
  as release optimizations. It's not clear from the documentation if all of
  these are really supported. It just list a bunch of intrinsics from these
  that are.
 2014-04-30 17:41:15 +03:00
Ari Koivula d1fbc6dc80 Fix a small memory leak. 
- Malloced pointer returned by alloc_yuv_t was not being freed in
  substream_encode.

- Remove use of yuv_t from encode_one_frame, as it's not used there anymore.
 2014-04-30 11:15:34 +03:00
Ari Koivula d808fe3b02 Merge branch 'strategy_selector' 2014-04-29 15:36:48 +03:00
Ari Koivula bd7e021742 Modify strategyselector to work with VS2010. 
- VS doesn't have snprintf.

- VS doesn't support GCC attributes.

- Add defines for __SSE__ and __SSE2__ on VS.
 2014-04-29 15:29:06 +03:00
Laurent Fasnacht bf7e755cf7 Strategies and runtime detection/choice of best algorithm 2014-04-29 11:51:41 +02:00
Ari Koivula 27b94d4b45 Address gcc -Wtype-limits errors. 
- Fixes warnings in #19 and #16.
 2014-04-29 09:15:52 +03:00
Ari Koivula 2a17e9a7aa Merge branch 'sse_intrinsics' 2014-04-28 19:38:08 +03:00
Ari Koivula cecf4b0b4e Move __USE_MINGW_ANSI_STDIO to Makefile. 
- I'm not too clear on how this should be used, but having it in the source
  file after mingw stuff was included caused a warning about redefinition of
  __USE_MINGW_ANSI_STDIO.
 2014-04-28 19:37:37 +03:00
Ari Koivula 4e7e40054f Move picture-sse2.c to src/inline-optimizations/. 
- Having it in the src dir even though it's not a module on it's own breaks
  the scons build script. It's probably better to have these a little bit
  separated from the normal code anyway.
 2014-04-28 19:36:40 +03:00
Laurent Fasnacht d66f809734 reg_sad implementation using SSE2/SSE4.1 intrinsics 2014-04-28 15:36:58 +02:00
Ari Koivula 4490e8afd6 Remove depth dimension from picture->cu_array. 
- It isn't used for anything anymore.

- It was used in the past to hold information during search, but now that
  information is held in lcu_t structs.

Laurent Fasnacht 76ec605b72 SAO works with tiles now 2014-04-28 06:29:21 +02:00

Ari Koivula 145816cfb5 Move printing of CLI stuff to stderr. 
- Printing to stdout corrupts the stream when used with "-o -".
