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 5e2f22f447 Try to fix intra prediction mode coding for NxN. 
- Adjust predictor list to take modes from PUs in addition to 2Nx2N CUs.
- Change intra_get_dir_luma_predictor to take PU index instead of CU index.
- Comment prediction encoding now that I've had to look it up.
 2014-01-29 13:52:17 +02:00
Marko Viitanen 7a21b9b769 Changed lambda calculation to fix RDOQ issues, RDOQ is now in use by default. 2014-01-28 12:14:43 +02:00
Marko Viitanen 9f70bf74f0 Imported and converted RDOQ from HM 12.0, NOT WORKING YET 2014-01-27 14:34:58 +02:00
Marko Viitanen f5c2292e06 Added simple Makefile and header files needed to compile on linux 2014-01-27 14:34:09 +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.
 2014-01-14 18:39:24 +02:00
Ari Koivula 73fdc35c4f Try to implement 4x4 luma transform coding. 
- Doesn't work yet so it's disabled.
- Change encode_transform_coeff to accept PU (Prediction Unit) coordinates
  instead of CU coordinates because CUs are 8x8.
 2014-01-09 19:30:54 +02:00
Ari Koivula 61232b466c Move types to more appropriate places. 2013-11-12 12:44:58 +02:00
Ari Koivula 181a044b86 Merge branch 'sao' 2013-11-12 11:59:04 +02:00
Marko Viitanen 93f2b75df7 Fixed a bug in flat scaling list and disabled scaling list by default 2013-11-05 09:41:14 +02:00
Ari Koivula a57b938270 Add new module sao. 
- Move sao-stuff not directly related to encoding to sao-module.
- Calculate sao for all LCUs before encoding any of them. This is in
  preparation to doing the reconstruction line at a time instead of
  LCU at a time.
 2013-11-04 19:41:01 +02:00
Ari Koivula b6c5c87fb7 Merge branch 'master' into sao 
SAO needs to be coded before LCU data has been searched. Searching
has already been moved to happen before encoding in the master branch.

Conflicts:
	src/encoder.c
	src/picture.c
	src/picture.h
 2013-11-04 12:44:01 +02:00

Marko Viitanen 1b2b3c19bb Added option to enable residual coding skip when residual under threshold 2013-10-10 16:31:00 +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.
