Laurent Fasnacht bf7e755cf7 Strategies and runtime detection/choice of best algorithm 2014-04-29 11:51:41 +02:00
Ari Koivula 4e7e40054f Move picture-sse2.c to src/inline-optimizations/. 
- Having it in the src dir even though it's not a module on it's own breaks
  the scons build script. It's probably better to have these a little bit
  separated from the normal code anyway.

Laurent Fasnacht d66f809734 reg_sad implementation using SSE2/SSE4.1 intrinsics 2014-04-28 15:36:58 +02:00
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.

Ari Koivula 313466fdff Remove unused variables. 
- Working towards issue #11.

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

Marko Viitanen 21e02e2d7d Added 4x4 SATD (Hadamard) 
Taken from HM 13.0
 2014-04-02 11:12:42 +03:00
Ari Koivula 7328fc2897 Add special handling for bottom right LCU pixel. 
I didn't take into account that the reference pixel on the top-left of the
LCU gets over written if we just replace the top reference pixels for
current LCU with the bottom reference pixels after doing the search.
To handle this I copy the pixel that gets overwritten to the vertical
reference pixels.
 2014-03-19 16:01:31 +02:00
Ari Koivula 57ce7e990b Add new reference pixel buffer management to encoding loop. 
- This is necessary because after we add in-loop filters to be done per LCU,
  the reconstruction buffer will have the deblocked pixels. We only need the
  edge-pixels for intra prediction though so we just save those.

- Right now it only copies the pixels and passes them on to search, where
  the copied pixels are asserted to be the same ones we copy from
  reconstruction buffer.

- New yuv_t struct added for arrays of dynamic length. We might want to change
  other buffers to use it or something like it in the future.

Ari Koivula e66fe65f8b Fix compiler warnings for VS2010 /W4 in picture.c. 
- Working towards issue #11.
 2014-02-10 16:50:53 +02:00
Marko Viitanen 5f79f30b8c Added preliminary support for multiple reference frames 
L0 reference list is being updated and sent to bitstream but actual usage of other than default reference might break something.
 2014-02-10 11:32:48 +02:00
Ari Koivula 526e3f9790 Fix interpolated_sad not working with vectors pointing far outside the frame. 2014-02-07 14:24:18 +02:00
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.
 2014-01-31 16:54:43 +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 21678930b1 Add an alternate way of accessing pixel buffers. 2013-11-14 15:38:10 +02:00
Marko Viitanen 60cb42735e Fixed issues on compiling the encoder on linux 2013-11-13 08:46:31 +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 66fe302520 Fix cabac context for sao. HM accepts encoded sao. 2013-11-04 13:03:51 +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 d9e6d8413d Added coeff data to picture-struct 2013-10-18 11:39:32 +03:00
Ari Koivula d74d4e4ef1 Refactor intra sad calculation functions. 
- Move SATD (hadamart) code to it's own functions.
- Generate functions for fixed block sizes with macros, as if using templates.
- Define new interface with function pointer cost_16bit_nxn_func that different
  cost functions can use.
- Hide fixed size block cost functions with getters.

Ari Koivula 0df974cb0d Change sad functions to accept negative block widths. 
This makes boundary checking clearer.
 2013-10-11 14:11:21 +03:00
Ari Koivula 4e36992752 Move basic SAD functions to picture-module. 2013-10-10 21:49:41 +03:00
Marko Viitanen c9cf75775b Deblocking fix: store block residual status and use it in deblocking 2013-10-09 17:39:23 +03:00

Ari Koivula 86b4ee475a Refactor: picture.c remove leading whitespace. 
Changing indentation like this really messes with diff, so I did it in
a separate commit.
