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 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).

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
Ari Koivula 67a3d5542c Add better delta distortion calculation to sao. 2014-04-15 21:17:29 +03:00

Laurent Fasnacht 52ae027b3a Avoid undefined behavior in memcpy calls 
"The memcpy() function shall copy n bytes from the object pointed to by s2 into the object pointed to by s1. If copying takes place between objects that overlap, the behavior is undefined."

Ari Koivula 29787efbbc Fix whitespace. 
Fix some whitespace issues from a merge.
 2014-04-11 17:06:21 +03:00
Ari Koivula 83d5a4753d Move input resolution to the same line as internal resolution. 
The \n must have been left there by accident.
 2014-04-11 16:55:08 +03:00
Ari Koivula 0b5c357795 Move all output to stderr. 
It has to be in stderr to allow piping bitstream from stdout.
 2014-04-11 16:50:59 +03:00
Ari Koivula 115872b300 Add total running time to output. 2014-04-11 12:42:37 +03:00

Marko Viitanen a657cf84d9 Insert most probable (predicted) intra modes to RDO search 2014-04-10 15:59:36 +03:00
Marko Viitanen 05169d9476 Added more modes to RDO mode selection in intra search 
Now 8 best modes for sizes 4x4 and 8x8 are added to RDO checking and 3 for other block sizes as before, only applies when --rd 2

Ari Koivula 5fa5e01e05 Merge branch 'intra-cleanup' 
Conflicts:

 2014-04-10 13:51:14 +03:00
Ari Koivula 40c2fa4d46 Change intra reconstruction to use the same prediction function as search. 
- This fixes a bug with intra search. It sometimes used filtered reference
  pixels for 4x4 blocks leading to inaccurate cost estimate.
 2014-04-10 12:09:19 +03:00
Ari Koivula d5c3ad7a2b Move intra prediction generation to its own function. 2014-04-10 11:27:15 +03:00
Ari Koivula 088dd9ab96 Clean up intra mode search. 
- This changes the bitstream a little bit, because it changes the order in
  which the modes are tried and when two modes have the same cost the first
  one is chosen.

- Dst buffer was removes as it was no longer used.
 2014-04-10 10:25:57 +03:00
Marko Viitanen 43ae0a3b9a Implemented RDO cost calculation to Intra modes 2014-04-10 10:25:20 +03:00
Marko Viitanen c38ec1aa10 Added commandline option for RDO (--rd) 2014-04-09 12:29:15 +03:00
Marko Viitanen 6558c92020 Clean up get_coeff_cost() 
Since contexts were moved to cabac struct, there's no need to store contexts one by one
 2014-04-09 11:50:17 +03:00
Ari Koivula 92ac5025f9 Take intra mode based coeff scan mode into account for coeff bit cost. 
- Previously only diagonal scan mode, the most common one, would be used.

- This improved bdrate by 0.1-0.5 % for p0 and 0-0.2 % for p60.
 2014-04-09 10:44:44 +03:00
Ari Koivula c5dfcdf3aa Simplify scan mode selection. 
- The scan mode selection for chroma was a bit complicated so I checked it
  and it was all unnecessary. The mode selection is the same as for luma.
 2014-04-09 10:36:39 +03:00
Ari Koivula 3764688f84 Fix lambda initialization. 
- Lambda was initialized before slice type was set in encoder_control.
 2014-04-08 16:58:36 +03:00
Ari Koivula 0251bf5a1a Improve calculation of chroma coding cost for 4x4 blocks. 
- Adds calculation of chroma coefficient cost for 4x4 blocks.

- Previously there was no cost. Now the cost is added to the first prediction
  block for NxN.

- This fix should improve bdrate by about 1%.
 2014-04-08 12:43:26 +03:00
Ari Koivula 3c0977c7f3 Fix buffer overflow on copying of reference pixels. 
- Valgrind noticed this.

- Shouldn't affect anything as the buffer overflowed to pixel buffers which
  were initialized later.
