Ari Koivula 7532b789f8 Add -std=gnu99 for gcc. 
- std=c99 doesn't work because then struct timespec won't be defined.
 2014-06-17 16:15:39 +03:00
Ari Koivula 94bc457b6c Add option to disable fast intra search. 2014-06-17 15:32:05 +03:00
Ari Koivula e27fc875c0 Clean up intra search. 2014-06-17 15:09:12 +03:00
Ari Koivula e4d70ac1ab Use more starting points for smaller blocks in intra search. 2014-06-17 13:28:27 +03:00
Ari Koivula 9911c7553b Avoid unnecessary intra dir searching. 2014-06-17 13:11:35 +03:00
Ari Koivula bd16a55b9b Always check DC and planar intra modes. 
- At least one of them is always in predicted modes, but to make sure they
  are both included add them explicitly.
 2014-06-17 12:51:15 +03:00
Ari Koivula 70740da123 Add smarter rough intra search. 
- Directional intra mode search is done using halving search from the best
  known mode. Starting modes are vertical, horizontal and the 3 diagonal
  modes.

  as the strategy.
 2014-06-13 15:30:23 +03:00

Ari Koivula bb47534b88 Make encoder_state .c files their own compilation units. 
- It's good that this module has been chopped to smaller pieces, but lets
  avoid including .c files unless we really have to. These make pretty good
  submodules on their own so just make them their own compilation units.

- Move some stuff around to avoid having to forward declare them
  in encoderstate.c.

Ari Koivula dceb3da9b8 Fix bug in search relating to transform with no non-zero coefficients. 
- Because cost was calculated even though there were no coefficients, these
  very good modes were less likely to be selected.

- Added assert to encode_coeff_nxn to avoid these problems in the future.

- Helps with debugging.
 2014-05-16 05:44:03 +03:00
Ari Koivula ab4041c8fc Change cabac debug statements to show information better. 
- Show the number of bits when encoding multiple bins. I would like just the
  bits them selves in string form, but that's too much trouble for this.

- Print then as unsigned and coerce them to unsigned, as they are going
  get coerced to unsigned by the function call anyway.

- Change state to be less verbose.

Ari Koivula f0e990905e Remove chroma mode "36". 
- It's an unnecessary chore to handle this special case everywhere (it means
  chroma_mode == intra_mode). Better just to use the actual mode.
 2014-05-14 19:56:35 +03:00
Ari Koivula 60a0ba4280 Update VS project files to link win32-pthread. 
- I haven't found a good way of including external dependencies to VS projects
  yet. Win32-pthreads is assumed to be found at the same level as kvazaar dir
  and has the files x86/pthreadVC2.lib and x64/pthreadVC2.lib.

- Win32-pthreads also requires the pthreadVC2.dll to be in PATH when running
  the program. Not sure what to do about that yet. We might need an installer
  for windows to handle that.

- Disable openmp as it's no longer used.

- Stop linking Ws2_32.lib as that hasn't been used for ages.

Ari Koivula aee9bf2875 Re-add rdo control to transformskip decision. 
- It got left out when rewriting the function.
 2014-05-14 12:39:23 +03:00
Ari Koivula 9147b7acbf Split residual quantization to separate luma and chroma function. 2014-05-14 11:19:48 +03:00
Tapio Katajisto cc92cfee18 Added few warnings to Makefile 
Cleaned fme code a bit
 2014-05-14 01:49:34 +00:00
Tapio Katajisto efc43c8b3a Added fractional pixel motion estimation 
Added farctional mv support for inter recon

Added 1/8-pel chroma and 1/4-pel luma interpolation
 2014-05-14 01:42:02 +00:00
Ari Koivula e947bd4c0e Clean up trskip decision code and remove old code. 
- You can define structs inside functions! This changes everything!!

- Bitstream changes a little bit compared to old trskip decision. Bdrate
  change is insignificant though.
 2014-05-13 22:00:04 +03:00
Ari Koivula a3cdee9ec5 Move new trskip decision to a function. 2014-05-13 21:59:00 +03:00
Ari Koivula 2ff713ccb2 Add new implementation for trskip decision. 2014-05-13 21:57:45 +03:00
Ari Koivula 8b8da6f493 Make luma and chroma use the same quantization function. 
- Only thing not working was transform skip.
 2014-05-13 21:57:23 +03:00
Ari Koivula f0bfcedba2 Clean up coeff reconstruction code. 2014-05-13 21:56:10 +03:00
Ari Koivula 0c65a9b658 Remove abs_sum from coeff quantization. 
- It's meant for checking if there are any coefficients, but we don't use it
  and it's annoying to remember to initialize it and pass it around. The
  benefit should be quite small anyway.
 2014-05-13 21:54:34 +03:00
Ari Koivula 75042fc65d Move luma quantization to it's own function. 2014-05-13 21:34:06 +03:00
Ari Koivula ba3aaf3189 Expand chroma functions to parent function. 
- This was done so that making the function work with luma would be easier.
 2014-05-13 21:30:14 +03:00
Ari Koivula 637aceb495 Add TR_MAX_WIDTH. 
- Max transform size is constrained by but independent of LCU size.

- Luma and chroma now have the same stride for transform arrays.
 2014-05-13 21:22:40 +03:00
Ari Koivula 1c38209cab Add missing include. 2014-05-13 09:33:05 +03:00
Ari Koivula 13577562e5 Revert change to definition of LCU_WIDTH. 2014-05-13 09:28:01 +03:00
Ari Koivula fb763f7940 Move coefficient generation functions from encoder.c to transform.c. 
- These functions probably should have been there to begin with.
 2014-05-12 11:37:39 +03:00
Ari Koivula a3478ecd20 Move transform skip decision to it's own function. 2014-05-12 11:18:27 +03:00
Ari Koivula d9b890de6e Remove redundant variables. 
- Redefine LCU_WIDTH to be 64. Stuff will break horribly if it's
  anything else anyway.

- Add LCU_WIDTH_C for chroma LCU width. It should be more readable than the
  constant (LCU_WIDTH >> 1).
 2014-05-12 10:58:07 +03:00
Ari Koivula 59e0e98523 Separate luma and chroma coefficient generation variables. 2014-05-12 10:38:24 +03:00
Ari Koivula 0ca65e7606 Move chroma coefficient generation to it's own function. 
- It's time to chop up this monster that is encode_transform_tree.
 2014-05-12 10:24:06 +03:00
Ari Koivula 3c3c9a26c6 Move scan order selection to a function. 2014-05-12 08:47:16 +03:00
Ari Koivula 623d9001a8 Reorder chroma coefficient generation. 2014-05-12 08:47:16 +03:00
Ari Koivula 93141c7d2e Avoid unnecessary copying of predicted pixels when there are no coeffs. 
- These are probably from a time when reconstruction happened in this
  function.
 2014-05-09 16:39:58 +03:00
Ari Koivula 27ab882c25 Clean up coefficient generation. 2014-05-09 16:33:10 +03:00
Ari Koivula ce945ab4ef Handle coefficient initialization better. 
- Coefficients are no longer required to be pre-zeroed. The resulting zeroes
  are copied in even in the case where we already know they are all zeroes.

- Move cbf clearing code to only happen at the leaves of the recursion.

Laurent Fasnacht b48a687d3c Restored parallelism, but it will be done in another way... OpenMP is not very efficient in these kind of dynamic situation 2014-05-07 11:55:56 +02:00
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 eaf8835bda Add some comments and const qualifiers. 2014-05-06 19:20:38 +03:00
Ari Koivula 3910b7989a Clear old cbf data before recursion in encode_transform_tree. 
- Because encode_transform_tree also maintains the CBF data and assumes that
  the CBFs are initially zeroed, calling the function more than once would
  result in incorrect CBF data.
 2014-05-06 19:03:29 +03:00
Ari Koivula bdc16d2612 Improve cu_info coded block flag data structure a bit. 
- It works just like the old structure except that the flags are checked with
  bitmasks instead of having the flag value be propagated upwards. There isn't
  really any benefit to this because the flags still have to be propagated to
  parent CUs.

- Wrapped them inside a struct to make copying them easier. (Just need to copy
  the struct instead of making individual copies)
 2014-05-06 18:28:04 +03:00
Ari Koivula d123b98aea Remove unnecessary tertiary expressions from usages of CABAC_BIN. 2014-05-06 17:39:25 +03:00

It used to treat odd numbers as false.

Ari Koivula 42295d3cb9 Pass preprocessor defines for supported intrinsics in VS2010 explicitly. 
- _M_IX86_FP defines whether VS should generate code using SSE or SSE2
  instructions. It isn't correct to use it to check whether optional runtime
  optimizations should be compiled in. It's also not defined at all in 64-bit
  mode.

- So let's just keep it simple and give a list of everything that is supported
  as release optimizations. It's not clear from the documentation if all of
  these are really supported. It just list a bunch of intrinsics from these
  that are.
 2014-04-30 17:41:15 +03:00
Ari Koivula d1fbc6dc80 Fix a small memory leak. 
- Malloced pointer returned by alloc_yuv_t was not being freed in

Ari Koivula 2a17e9a7aa Merge branch 'sse_intrinsics' 2014-04-28 19:38:08 +03:00
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.
 2014-04-28 19:37:37 +03:00
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 61c67dc485 Allow -DUSE_TILES=1 to be specified in Makefile; define MAX_TILES_PER_DIM. 2014-04-24 08:38:11 +02:00
Laurent Fasnacht 19b1642aa2 Removed all cabac parameters (cabac is part of encoder_state) 2014-04-22 11:46:53 +02:00
Ari Koivula a539ae7e08 Address clang-analyzer warning. 
- The assert needs to be before the initialization.
 2014-04-22 11:55:28 +03:00
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.
 2014-04-22 10:39:12 +02:00
Ari Koivula 88a67a4e49 Fix faulty assert that stops the program from working with inter frames. 
- The assert would be true after the next if block, but in it's current place
  it's false.
 2014-04-22 10:57:38 +03:00
Ari Koivula 54270f271d Fix c89 problem to allow compilation with VS2010. 2014-04-17 19:12:39 +03:00
Ari Koivula 1b437a5989 Address clang-analyzer warnings about garbage values. 
- False alarm, but surprisingly difficult to convince clang of that. It
  doesn't seem to understand bit shifts very well.

- Only assert and changing LCU_WIDTH>>depth to width was necessary to satisfy
  clang.

- Closes #35.
 2014-04-17 18:43:09 +03:00
Ari Koivula 11509c68dc Address clang-analyzer warnings about unused values. 
- Related to issue #35.

- Related to issue #35.
 2014-04-17 18:43:08 +03:00
Ari Koivula 32da12f653 Address a clang-analyzer warning about undefined behavior in filter. 
- Analyzer didn't see that code is never called with MAX_DEPTH as it doesn't
  know the properties of width, height, x and y. Following would also
  silence the error:
    assert(cur_pic->width > 0 && cur_pic->height > 0);
    assert(cur_pic->width % 8 == 8 && cur_pic->height % 8 == 0);
    assert(x > 0 && y > 0);
    assert(x % 8 == 0 && y % 8 == 0);

- Related to issue #35.

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.
 2014-04-17 11:58:03 +03:00
Ari Koivula b35f33b3da Address warnings about unused values. 
- Related to issue #35.
 2014-04-16 18:05:03 +03:00
Ari Koivula 9229e5d11b Fix undefined behavior of EO_IDX. 
- Move the whole eo_cat thing to it's own function.

- Casting pixel values to int should solve issues with SIGN3. Not casting them
  was detected as undefined behavior by CLANG. Probably because the result of
  two unsigned might be treated as unsigned (but isn't on VS2010).
 2014-04-16 14:50:19 +03:00

Ari Koivula 880d09b27a Add sao_type_idx to SAO mode cost estimation. 2014-04-15 21:29:09 +03:00
Ari Koivula 280a946269 Apply bit cost fixes to edge band band sao search. 
- Increases bdrate slightly. It's still a cleaner solution though and further
  improvements to bit cost estimation might improve things.
 2014-04-15 21:28:16 +03:00
Ari Koivula c968253eb3 Estimate SAO merge coding costs better. 
- This doesn't seem to have very much of an effect. I guess the difference
  between 1 and 2 bits isn't that important.
 2014-04-15 21:27:16 +03:00
Ari Koivula ef7840c623 Add SAO coding costs for sao_eo_class, band position and offset sign. 
- This reduces bdrate a little bit.

- It seems like increasing the bit cost of using SAO in general
  increases bdrate.
 2014-04-15 21:24:44 +03:00
Ari Koivula 9ff32c566c Adjust SAO mode coding cost for zero offsets. 
- Coding zero with TR only takes one bit.

- Even though offset 0 should be fairly common, this doesn't seem to help very
  much and actually increases bdrate on some sequences.
 2014-04-15 21:21:31 +03:00

Fix some whitespace issues from a merge.
 2014-04-11 17:06:21 +03:00
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.

Marko Viitanen 05169d9476 Added more modes to RDO mode selection in intra search 
Now 8 best modes for sizes 4x4 and 8x8 are added to RDO checking and 3 for other block sizes as before, only applies when --rd 2

 2014-04-10 13:51:14 +03:00
Ari Koivula 40c2fa4d46 Change intra reconstruction to use the same prediction function as search. 
- This fixes a bug with intra search. It sometimes used filtered reference
  pixels for 4x4 blocks leading to inaccurate cost estimate.
 2014-04-10 12:09:19 +03:00
Ari Koivula d5c3ad7a2b Move intra prediction generation to its own function. 2014-04-10 11:27:15 +03:00
Ari Koivula 088dd9ab96 Clean up intra mode search. 
- This changes the bitstream a little bit, because it changes the order in
  which the modes are tried and when two modes have the same cost the first
  one is chosen.

- Dst buffer was removes as it was no longer used.
 2014-04-10 10:25:57 +03:00
Marko Viitanen 43ae0a3b9a Implemented RDO cost calculation to Intra modes 2014-04-10 10:25:20 +03:00

Marko Viitanen 6558c92020 Clean up get_coeff_cost() 
Since contexts were moved to cabac struct, there's no need to store contexts one by one
 2014-04-09 11:50:17 +03:00
Ari Koivula 92ac5025f9 Take intra mode based coeff scan mode into account for coeff bit cost. 
- Previously only diagonal scan mode, the most common one, would be used.

- This improved bdrate by 0.1-0.5 % for p0 and 0-0.2 % for p60.
 2014-04-09 10:44:44 +03:00
Ari Koivula c5dfcdf3aa Simplify scan mode selection. 
- The scan mode selection for chroma was a bit complicated so I checked it
  and it was all unnecessary. The mode selection is the same as for luma.
 2014-04-09 10:36:39 +03:00
Ari Koivula 3764688f84 Fix lambda initialization. 
- Lambda was initialized before slice type was set in encoder_control.
 2014-04-08 16:58:36 +03:00
Ari Koivula 0251bf5a1a Improve calculation of chroma coding cost for 4x4 blocks. 
- Adds calculation of chroma coefficient cost for 4x4 blocks.

- Previously there was no cost. Now the cost is added to the first prediction
  block for NxN.

- This fix should improve bdrate by about 1%.
 2014-04-08 12:43:26 +03:00
Ari Koivula 3c0977c7f3 Fix buffer overflow on copying of reference pixels. 
- Valgrind noticed this.

- Shouldn't affect anything as the buffer overflowed to pixel buffers which
  were initialized later.
 2014-04-04 17:28:56 +03:00
Ari Koivula 6e0bc655e2 Resolve unused variable warning. 
- This unexpectedly changes bitstream, but as that makes no sense, it must be
  because some part of the program uses uninitialized memory.

Laurent Fasnacht 946c815932 init_context directly has a QP parameter, instead of passing an encoder_control* 
This makes context less tightly coupled with encoder.

Ari Koivula 7239b59e94 Resolve constant conditional expression warning. 
- Working towards issue #11.

- I felt that the macro was a little bit too clever in hiding the if-else

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

Marko Viitanen cfb21c0e4c Implemented transform skipping (for 4x4 blocks) 
transform skip vs. normal transform selection criteria might need more work, currently both are calculated for each 4x4 block and SAD+coeff_SSE is compared.

Ari Koivula 0f492c7680 Fix deblocking of transform boundaries. 
This fixes issues with inter. Deblocking works now.
 2014-03-21 10:42:41 +02:00
Ari Koivula c42b25054a Modify deblocking to be done per-LCU in the encoding loop. 
- Intra works. There is still something wrong in inter.

- Avoid horizontal deblocking of the rightmost 4 pixels in the LCU.
  This is because vertical deblocking must be done for all pixels
  before horizontal, but vertical deblocking can't be done for those
  pixels before the next LCU is finished.

- Add separate deblocking of the rightmost pixels of the last LCU
  after the LCU edge has been deblocked.

- This is a pretty ugly hack but will have to do for now.
 2014-03-20 18:14:43 +02:00
Ari Koivula bbd1202f90 Replace old LCU reference pixels initialization with new ones. 
In the future we might even have just a const pointer to reference pixels.
 2014-03-19 16:01:31 +02:00
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 34e453c880 Clean up encode_one_frame. 
There is a lot of duplicated code due to handling random access and trailing
pictures separately. I merged the code for these two branches so it would be
easier to modify.
 2014-03-17 18:04:41 +02:00
Ari Koivula b1596eb76c Refactor coding of end_of_slice_segment_flag. 
According to spec the end_of_slice_segment_flag is always coded, but in the
code it looked like it was not coded for the last LCU in picture. This was
due to the end_of_slice_segment_flag being coded inside cabac_flush, like it
is in HM. This is a bit silly so I moved it out of cabac_flush.
 2014-03-17 18:04:41 +02:00
Ari Koivula 6a384112cc Remove old unnecessary functions from search module.

Ari Koivula 9563b50a34 Refactor coefficient group scan mapping lists. 
The relation between coefficients positions and coefficient group positions
was a big confusing due to the use of 16x16 diagonal coefficient mappings
also as coefficient group mappings.

- Moved all coefficient group mappings to their own const arrays and added
  a new array the select the correct coefficient group mapping. This removes
  special cases for 8x8 and 32x32 transform sizes.

- Removed all coefficient group mapping initialization from init_sig_last_scan.

- Removed 128x128 and 64x64 from regular coefficient group array as those
  transform sizes don't exist anymore in HEVC.

  the LCU before we start compressing the next LCU so we can update CABAC

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 13dc95a164 Implemented band SAO reconstruction 2014-02-21 11:52:41 +02:00

Something must be done to enable better selection of NxN blocks in order to gain BD-rate with this mode.
 2014-02-19 14:36:17 +02:00
Marko Viitanen 3618eab72a Added lambda cost when using reference frames with refIdx > 0 
Because selecting references "far away" costs bits, this should help with the issue that multiple reference frames actually increases coded bits with no quality gain.
 2014-02-19 14:34:36 +02:00
Marko Viitanen 478552ea00 Added commandline parameter for reference frame number

Ari Koivula 8e63dd29bb Fix compiler warnings for VS2010 /W4 in intra.c. 
- Working towards issue #11.
- Removed intra_get_block_mode as unused.
- Removed unused parameters from functions. Many of them were remnants from
  earlier data structures and earlier features of HEVC that have been removed.
- Lots of implicit conversions from larger types to smaller ones. I tried to
  avoid turning all of them to explicit ones this time and opted for changing
  the original data type instead. Had to do it in few cases though to stop the
  changes from propagating too widely.
 2014-02-14 17:15:54 +02:00
Marko Viitanen a6e8373349 Fixed crash issue on windows when cqmfile was not specified

Ari Koivula ea312082a4 Simplify the prediction mode search recursion. 
No need to be so clever for something this simple.

I moved the cost initialization outside the recursing function because it
relied on the clever recursion to work. It should eventually be moved to its
own function that also initializes all the other fields just to be safe. I
didn't do that yet because I want to do it per-LCU and these functions are
still working on per-frame basis.

Ari Koivula 7bb9c25447 Remove duplicate implementation of intra_build_reference_border. 
The search_buildReferenceBorder was an ugly hack and a place for bugs to hide
that should never have existed. Now it doesn't.

The change reduces PSNR a little, but also reduces the bitrate, when the
expected result was to have no change in either. I'm guessing there was still
some bug in the search_buildReferenceBorder, but the bug could also be in
intra_build_reference_border. Will have to do more testing to be sure, but
having one place to look at will be better than having two.

Ari Koivula bf80007270 Try to fix 4x4 luma coding. 
Still doesn't work. I have no idea what the problem is. Probably somehow related to the coefficient coding, since the bitstream seems to work, the prediction is correct and the error is not very severe.

- Change scan order selection to be more verbose and based on the correct mode for 4x4. Didn't affect the problem with 4x4 luma in any way although it should have.
- Re-enable residual coding as everything seems to work now besides 4x4 luma.

New implementation uses precalculated tables to look up number of reference
pixels available in coded CUs. Otherwise it works just like the previous
version.

- NxN mostly works. Prediction appears to be almost correct but there is a
  slight error in the exact values, probably related to filtering.

Ari Koivula 91024a2095 Disable deblocking because it breaks sao. 2013-11-04 20:51:51 +02:00
Ari Koivula f21df00386 Save a copy of luma for sao. 2013-11-04 20:33:29 +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.

Ari Koivula 03f2967899 Block based sao dead end. 
This will never work because the adjacent blocks require the original values
of the boundary pixels to make category decisions.

Ari Koivula 31af7e3929 Fix sao offsets. Reconstruction kind of works. 2013-11-04 13:05:05 +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.

Ari Koivula 0fd9105f0a Fix sao type context init values. 
The initialization slice types are in reverse order compared to the codes used
for slice types. They are BPI instead of IPB.
