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 de1c0b7e8d Fixed intra RDO to include mode bitcost 2014-04-10 16:28:41 +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 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.

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.
2014-04-04 17:28:56 +03:00
Ari Koivula 6e0bc655e2 Resolve unused variable warning.
- This unexpectedly changes bitstream, but as that makes no sense, it must be
  because some part of the program uses uninitialized memory.

Marko Viitanen 234b6ed48c Merge commit 'e15a86268def51984b2ff4efc966ddfa74ca3fa2' 2014-04-04 16:07:57 +03:00

Laurent Fasnacht 816ae13b1d Moved context information inside cabac_data.
This is required in order to be able to work on parallelism.
2014-04-04 14:28:50 +02:00
Laurent Fasnacht 8a14bd3b7b Remove cabac global variable 2014-04-04 14:26:40 +02:00
Laurent Fasnacht 946c815932 init_context directly has a QP parameter, instead of passing an encoder_control*
This makes context less tightly coupled with encoder.
2014-04-04 14:26:39 +02:00
Laurent Fasnacht 1e03cf8ac1 Add a function to free g_exp_table.
Even though g_exp_table has to be global (used in #define), it's better to avoid requiring other module to directly access it.
2014-04-04 14:26:39 +02:00
Marko Viitanen 7484dafd82 Fix for get_coeff_cost() scan mode selection

Ari Koivula e4b942ad67 Enable /W4 for VS.
- Disabled errors are:
 - Implicit conversion from bigger to a smaller type. I don't want to disable
   it but there are still about 60 of these and adding explicit C casts
   everywhere is just going to cause more problems.
 - Nonstandard extension: Non-constant aggregate initializer.
 - Translation unit is empty.

Ari Koivula 61256fc31a Enable -Wall by default. 2014-04-04 13:02:08 +03:00
Ari Koivula 69ac9176a5 Disable warnings for extras/getopt.
- This isn't our code so we don't care about these warnings.
2014-04-04 13:02:08 +03:00
Ari Koivula 7239b59e94 Resolve constant conditional expression warning.
- Working towards issue #11.

- I felt that the macro was a little bit too clever in hiding the if-else
  statements so I removed that aspect, which also has the minor benefit of not
  requiring the starting if (0) statement.
2014-04-04 13:02:07 +03:00
Ari Koivula b19e4f3f2d Resolve possible uninitialized variable warnings.
- Working towards issue #11.

- Neither variable was actually used as uninitialized.

2014-04-04 12:56:23 +03:00
Ari Koivula c142cbba21 Fix typo.
- Obvious typo. This g_bitdepth - 8 used to be g_bitincrement. Doesn't affect
  anything yet as we don't actually support bitdepth > 8 yet.

Marko Viitanen 5bebb34787 Merge pull request #22 from lfasnacht/realloc_fix
Use realloc correctly
2014-04-04 08:28:15 +03:00
Laurent Fasnacht b371a8bb59 Use realloc correctly
Quote from MALLOC(3) manpage:

The realloc() function returns a pointer to the newly allocated memory, which is suitably aligned for  any  kind  of
variable and may be different from ptr, or NULL if the request fails.
2014-04-04 06:37:35 +02:00
Ari Koivula 0074cd1a98 Add extra parenthesis to suppress compiler warnings. 2014-04-03 15:38:18 +03:00
Ari Koivula 27a3329dfb Remove unreferenced_parameter macro.
- It was a silly hack to selectively silence compiler warnings from VS, but
  there is no point as it causes compiler warnings in GCC.
2014-04-03 15:38:17 +03:00
Ari Koivula f380e7d4b0 Check for malloc failure. 2014-04-03 15:38:17 +03:00
Ari Koivula 313466fdff Remove unused variables.
- Working towards issue #11.

- Either removed or redefined variables to not cause a warning.

Marko Viitanen 0da8071300 Changed final cost (and transform skip) error function from SAD to SSD 2014-04-02 14:51:39 +03:00
Marko Viitanen a14fb14e33 Added new commandline parameter --no-transform-skip 2014-04-02 14:49:48 +03:00
Marko Viitanen 21e02e2d7d Added 4x4 SATD (Hadamard)
Taken from HM 13.0
2014-04-02 11:12:42 +03:00
Marko Viitanen cfb21c0e4c Implemented transform skipping (for 4x4 blocks)
transform skip vs. normal transform selection criteria might need more work, currently both are calculated for each 4x4 block and SAD+coeff_SSE is compared.

Marko Viitanen b9f8950cf7 Merge pull request #21 from lfasnacht/global-h-rewrite
Improved clarity of src/global.h
2014-04-01 15:15:00 +03:00
Laurent Fasnacht ae5c573843 Global defines are now documented with references the specification when possible. Removes some redundancy. 2014-04-01 13:48:17 +02:00
