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.

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.

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.

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.

Laurent Fasnacht 418e6eae51 Changed bitstream handling to allow in-memory bitstream. 2014-04-14 08:13:00 +02:00
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 c38ec1aa10 Added commandline option for RDO (--rd) 2014-04-09 12:29:15 +03:00
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
Ari Koivula 61ae195af7 Resolve warnings about assignments within conditions.
- Working towards issue #11.

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 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.
2014-04-03 15:37:59 +03:00
Marko Viitanen a14fb14e33 Added new commandline parameter --no-transform-skip 2014-04-02 14:49:48 +03:00
Panu Sjövall c8f629495d Remove unnecessary buffer from bitstream.
- Writing encoded data to file is done in bitstream_put one byte at a time and nal_write only writes the packet headers
2014-03-25 11:46:56 +02:00
Ari Koivula eacad83ff9 Fix encoder reconstruction output for non multiple of 8 sized input.
Output changed so that only pixels within the conformance window are output.
2014-03-19 13:24:01 +02:00
Ari Koivula 319174258b Increment version number and update usage information. 2014-03-12 18:06:41 +02:00
Marko Viitanen 17b9c9d0b7 Unified all uses of --input-res to use 'x' as delimiter
Addresses issue #20
2014-03-12 15:20:57 +02:00
Marko Viitanen d2d877933a bugfix: only fclose recout if it was opened 2014-03-11 09:09:43 +02:00
Ari Koivula 1b2705a042 Add video dimensions to the filename of encoder reconstruction. 2014-03-10 18:10:50 +02:00
Ari Koivula 965d8c377a Make encoder reconstruction obey --debug. 2014-03-10 18:10:49 +02:00
Ari Koivula 7e507fd615 Add --input-res CLI parameter.
- Also set default width and height to 0 because it makes no sense to assume
  dimensions. It's kind of like defaulting to the most common altitude when
  the altimeter is broken.
- Add config_validate to have a place for checks on overall cfg state.
2014-03-10 16:09:33 +02:00
Ari Koivula a644848b36 Add --seek CLI parameter.
Related to issue #12.

Motivation for adding this is that the syntax for frame accurate seeking in
ffmpeg is a little cumbersome. Also it's kind of a standard feature I guess.
2014-03-10 15:14:56 +02:00
Marko Viitanen a935aa5d96 Untabified encmain.c and nal.c 2014-03-10 12:10:40 +02:00

Ari Koivula 1cf03cfb37 Add --no-rdoq parameter. 2014-03-05 17:02:21 +02:00
Ari Koivula 73f5c3b80e Fix compiler warnings for VS2010 /W4 in config.c and encmain.c.
- Working towards issue #11.
- Widened datatypes for cfg struct members that take values from atoi to full
  ints so that bounds checking can be done after parsing without overflow.
2014-02-21 17:28:11 +02:00
Luca Barbato 47677af690 Drop remaining unused variables 2014-02-21 15:07:16 +01:00
Luca Barbato 934a4e3b88 whitespace: Drop trailing spaces 2014-02-21 15:03:35 +01:00
Ari Koivula 5760c79272 Fix crash with dimensions that are not multiples of 8.
The clean up of input parsing and encoder initialization code had caused the
real source input dimensions to be used for array initialization, instead of
the dimensions modified to be multiples of the smallest coding unit.
2014-02-21 12:48:33 +02:00
Marko Viitanen bb1ae0da62 Limited maximum number of reference frames to 15
This now complies with the specification (when using only L0 reference list)
2014-02-20 11:09:09 +02:00
Marko Viitanen db689227f4 Increased maximum ref frame count to 16 and set default to 3 2014-02-19 15:09:17 +02:00
Marko Viitanen 478552ea00 Added commandline parameter for reference frame number
Also updated README and usage with the new parameter
2014-02-18 17:45:54 +02:00
Marko Viitanen a6e8373349 Fixed crash issue on windows when cqmfile was not specified
fclose(cqmfile) crashed on windows when cqmfile was NULL
2014-02-14 14:38:53 +02:00
Yusuke Nakamura a860bbc7f9 config: Add --cqmfile to use custom quantization matrices from a file.
The coefficients in a matrix are stored in up-right diagonal order.

The following indicates the default matrices specified in the spec.

  correct newlines for different platforms.

Marko Viitanen ffd00695c7 Better cleanup of allocated memory at exit
Using valgrind all the leaks were tracked and fixed.

allocation fails.

Marko Viitanen ac8141b328 Fixed a bug in intra search and some memory leaks, changed version to 0.2.1
Intra search was using faulty border data and selected modes were a bit random. Around -0.5% (LP) and -2% (AI) change in BD-rate was seen in limited testing conditions.

Marko Viitanen 76f24408b6 Included x264asm abstraction layer -library and fixed Makefile
Name mangling is causing problems on different platforms (issues #2 and #3) and some of it was solved modifying the Makefile. Separate 32bit and 64bit assembly functions were also causing problems and since we were going to move to x264asm abstraction layer anyway, we decided to do it now before spending time on the old implementation.

Ari Koivula 5d12706510 Merge branch 'intra_NxN'
Conflicts:
	src/encoder.c

- Chroma RDOQ changes conflicted because I had moved the chroma
  quantization/dequantization to it's own function.
- Merged to master because I want my code to show up in github. =)
  All the old stuff still works, even though NxN doesn't work, so there
  is no reason not to merge anyway.
2014-01-29 17:04:41 +02:00
Ari Koivula e33655fde5 Remove debug stuff and disable intra NxN in preparation for a merge.
- Re-enable intra search based on reconstructed image.
  - This didn't have as much of an effect as I thought it would.
- Re-enable SAO and deblocking.
- Disable NxN searching. (4x4 luma coding is still broken)
2014-01-29 16:45:37 +02:00
Ari Koivula 71a996f50f Work on reconstruction and searching.
- Set part-size for Inter.
- Change to Intra Only mode for testing.
- Many small changes here and there. Should have been separate commits probably, but too late.
- Disable SAO and deblocking to be able to see problems with reconstruction better.
