Ari Koivula b14f89c88f Rename struct encoder_state to encoder_state_t. 2015-03-04 14:00:46 +02:00
Ari Koivula d7383ccb25 Change license to LGPL.
- Everyone who has contributed code to the project has been asked to license
  their contributions under LPGL and they have agreed.

- COPYING file changed to say LGPLv2.1 instead of GPLv2.

- GPL changed to LGPL in the header of every single file that a header and
  header added to the few that were missing one.

- Also.. Happy new year!

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 5e7945888a Inter-frame prediction with tiles works.
Many thanks to Jean-Hugues Recolin for the insightful comments about shifts!

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 478740cf21 Add missing new lines to ends of files. 2014-02-03 16:54:03 +02:00
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 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.
2014-01-29 14:18:01 +02:00
Ari Koivula 77339efa57 Add COPYING file and add boilerplate for copyright and GPLv2 to every file. 2014-01-24 12:48:48 +02:00
Ari Koivula a38a5fd647 Improve transform tree coding.
- Clean up code and comment.
- Change terminology to match H.265 specification where possible.
- Move transform splitting for depth==0 out of the coding part. It's not
  possible to do it here anyway because intra reconstruction is different
  if the transform is split.
- Add checking for transform hierarchy depth when coding split flag.
- Fixes bug with cu_data.tr_depth being set. The CU struct was being reused
  for inter coded CUs, which did not initialize the tr_depth.

Marko Viitanen 13bbd2fb37 Fixed inter_get_mv_cand() candidate selection of B0 CU 2013-10-02 15:10:40 +03:00
Ari Koivula 681975ad4b Fix inter reconstruction for 8x8 blocks and enable 8x8 inter blocks again.
Inter reconstruction was modifying the movement in place when it shouldn't
have. This was causing issues only for the 8x8 blocks, because for larger
blocks the modified movement vector was too far away to be seen by the blocks
below it.
2013-09-30 18:01:21 +03:00
Ari Koivula 04f1dde8a1 Fix overwriting of motion vectors during search.
- Makes everything besides search to only use the bottom most layer of the
  picture.cu_array structure.

Marko Viitanen 0bf4f65a55 Refactor: encoder.h renaming 2013-09-18 14:49:01 +03:00
Ari Koivula 44a5498e30 Reorder includes to avoid hidden dependencies.
- Includes of global.h have been moved to headers because most headers
  require stdint.h.
- Includes required by the header have been moved from the .c to the header.
- Spaces have been added between includes to distinguish classes of includes.
