Ari Koivula 2f79bfebf7 Rename parameter encoder_state to state in all functions. 
- It's so widely used that there isn't really need to emphasize that
  it's the encoders state. Also, it isn't really the encoders state,
  but encoding jobs state.

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.

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.

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.
