Laurent Fasnacht 61c67dc485 Allow -DUSE_TILES=1 to be specified in Makefile; define MAX_TILES_PER_DIM. 2014-04-24 08:38:11 +02:00
Laurent Fasnacht 19b1642aa2 Removed all cabac parameters (cabac is part of encoder_state) 2014-04-22 11:46:53 +02:00
Ari Koivula a539ae7e08 Address clang-analyzer warning. 
- The assert needs to be before the initialization.
 2014-04-22 11:55:28 +03:00
Laurent Fasnacht a44a396ba2 Add Laurent to CREDITS :-) 2014-04-22 10:40:00 +02:00
Laurent Fasnacht 5fea5875a5 Huge refactoring 
Split some parts of encoder_control into encoder_state
(idea: encoder_control is immutable)

Goal is to allow multiple substreams in the future.
 2014-04-22 10:39:12 +02:00
Ari Koivula 88a67a4e49 Fix faulty assert that stops the program from working with inter frames. 
- The assert would be true after the next if block, but in it's current place
  it's false.
 2014-04-22 10:57:38 +03:00
Ari Koivula 54270f271d Fix c89 problem to allow compilation with VS2010. 2014-04-17 19:12:39 +03:00
Ari Koivula 1b437a5989 Address clang-analyzer warnings about garbage values. 
- False alarm, but surprisingly difficult to convince clang of that. It
  doesn't seem to understand bit shifts very well.

- Only assert and changing LCU_WIDTH>>depth to width was necessary to satisfy
  clang.

- Closes #35.
 2014-04-17 18:43:09 +03:00
Ari Koivula 11509c68dc Address clang-analyzer warnings about unused values. 
- Related to issue #35.
 2014-04-17 18:43:08 +03:00
Ari Koivula 0704c43836 Address clang-analyzer warning about undefined behavior in intra. 
- Related to issue #35.
 2014-04-17 18:43:08 +03:00
Ari Koivula 32da12f653 Address a clang-analyzer warning about undefined behavior in filter. 
- Analyzer didn't see that code is never called with MAX_DEPTH as it doesn't
  know the properties of width, height, x and y. Following would also
  silence the error:
    assert(cur_pic->width > 0 && cur_pic->height > 0);
    assert(cur_pic->width % 8 == 8 && cur_pic->height % 8 == 0);
    assert(x > 0 && y > 0);
    assert(x % 8 == 0 && y % 8 == 0);

- Related to issue #35.

Laurent Fasnacht 677fc2ec7d Fix prototype of create_bitstream in bitstream.h 2014-04-17 11:13:08 +02:00
Ari Koivula 51ba80513b Centralize resource deallocation for encmain. 
- CppCheck was complaining about unreleased resources for FILE*. They weren't
  really because they get flushed and closed when program exits normally, but
  let's close them anyway.
 2014-04-17 11:58:03 +03:00
Ari Koivula b35f33b3da Address warnings about unused values. 
- Related to issue #35.
 2014-04-16 18:05:03 +03:00
Ari Koivula 9229e5d11b Fix undefined behavior of EO_IDX. 
- Move the whole eo_cat thing to it's own function.

- Casting pixel values to int should solve issues with SIGN3. Not casting them
  was detected as undefined behavior by CLANG. Probably because the result of
  two unsigned might be treated as unsigned (but isn't on VS2010).

Laurent Fasnacht 9112cbb58c Generate and use static tables 2014-04-16 09:49:09 +02:00
Ari Koivula a982800e1b Merge remote-tracking branch 'remotes/lfasnacht/const' 2014-04-16 10:28:31 +03:00
Ari Koivula df5af669f9 Merge remote-tracking branch 'remotes/lfasnacht/makefile_deps' 2014-04-16 10:28:04 +03:00
Ari Koivula 33b9594fec Take into account the coding cost of not using SAO. 2014-04-15 21:32:24 +03:00
Ari Koivula 880d09b27a Add sao_type_idx to SAO mode cost estimation. 2014-04-15 21:29:09 +03:00
Ari Koivula 280a946269 Apply bit cost fixes to edge band band sao search. 
- Increases bdrate slightly. It's still a cleaner solution though and further
  improvements to bit cost estimation might improve things.
 2014-04-15 21:28:16 +03:00
Ari Koivula c968253eb3 Estimate SAO merge coding costs better. 
- This doesn't seem to have very much of an effect. I guess the difference
  between 1 and 2 bits isn't that important.
 2014-04-15 21:27:16 +03:00
Ari Koivula ef7840c623 Add SAO coding costs for sao_eo_class, band position and offset sign. 
- This reduces bdrate a little bit.

- It seems like increasing the bit cost of using SAO in general
  increases bdrate.
 2014-04-15 21:24:44 +03:00
Ari Koivula 9ff32c566c Adjust SAO mode coding cost for zero offsets. 
- Coding zero with TR only takes one bit.

- Even though offset 0 should be fairly common, this doesn't seem to help very
  much and actually increases bdrate on some sequences.
 2014-04-15 21:21:31 +03:00
