Ari Koivula 846b608125 Add transform split recursion to intra reconstruction. 2014-05-19 15:58:54 +03:00
Ari Koivula 63f6cad5a0 Include global.h in thread modules. 2014-05-19 15:58:16 +03:00
Ari Koivula 551b087b47 Remove bunch of unnecessary code from encode_transform_unit. 
- Really, it's useless. Selecting scan order isn't this hard.

- Checked from HM that ctx_idx doesn't have anything to do with contexts.
 2014-05-16 17:42:40 +03:00
Ari Koivula f73bef0941 Remove unused include. 2014-05-16 16:09:59 +03:00

Laurent Fasnacht 4f73a7fc91 Instrument threads in order to be able to do some visualization 2014-05-16 08:44:32 +02:00
Ari Koivula a7cd31d87b Update the names of some bins to the current spec. 
- 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.
 2014-05-16 05:44:03 +03:00
Ari Koivula c9a8756fbd Fix NxN scan mode for lcu_get_final_cost. 
- Scan mode was always selected according to the first PU mode.
 2014-05-15 16:20:35 +03:00
Marko Viitanen b08047cce9 Fixed intra chroma mode selection 2014-05-15 09:50:05 +03:00
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.

Laurent Fasnacht baede7f6c4 threadqueue 2014-05-14 13:27:08 +02:00
Laurent Fasnacht 8b7774153f Add SLEEP() define 2014-05-14 13:27:08 +02:00
Laurent Fasnacht aac7fc55b1 Remove filter_deblock function, which is not used and somewhat dangerous, since it doesn't take into account specific stuff about subencoders. 2014-05-14 13:27:07 +02:00
Laurent Fasnacht bc3ca90bdf Fix tiles when SAO or deblock is enabled. 
Was broken by previous commit.
 2014-05-14 13:27:07 +02:00
Laurent Fasnacht 4815a0604b Entropy coding sync works without parallelism, without SAO and without deblocking 2014-05-14 13:27:06 +02:00
Laurent Fasnacht 2c2a2528f3 Remove openmp stuff 2014-05-14 13:27:06 +02:00
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
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.

Seems to be OK with HM now
 2014-05-09 12:42:37 +02:00
Laurent Fasnacht 43b5f84c0d Fix sao_calc_edge_block_dims 
It was computing wrong dimensions, which was causing out-of-bounds reads in sao_reconstruct.
 2014-05-09 10:30:34 +02:00
Laurent Fasnacht 3f975e92cd Replace line fixing symptoms by assertions, to reveal the cause 2014-05-09 08:24:03 +02:00

Ari Koivula 535b42bc9b Fix compilation for VS2010. 2014-05-07 15:26:44 +03:00
Laurent Fasnacht 05eef82896 Remove extra [ from graphviz dump 2014-05-07 13:40:29 +02:00
Laurent Fasnacht 84e5dbee39 Remove quote from graphviz dump 2014-05-07 13:33:02 +02:00
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.
 2014-05-07 11:55:48 +02:00
Laurent Fasnacht 39d96e0546 Fix bug with cabac stream pointing to bad data 2014-05-07 11:55:41 +02:00

Laurent Fasnacht c2872bd6b0 Slices and WPP in command line and encoder 2014-05-07 11:42:04 +02:00
Laurent Fasnacht 2d6f199246 reorganized encoder_state structure 2014-05-07 11:41:27 +02:00
Laurent Fasnacht f0b076876f Moved all the stream related stuff into substream_write_bitstream 2014-05-07 11:40:20 +02:00
Laurent Fasnacht f30b9c2a11 Fix a buffer overflow in parse_tiles_specification 2014-05-07 11:39:45 +02:00
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
Ari Koivula 380401b2eb Have CABAC_BIN accept any >0 as binary 1. 
It used to treat odd numbers as false.
 2014-05-06 17:39:10 +03:00
Marko Viitanen bf2c2a1330 Small changes to fix compiling on VS 
- Added threads.h to VS project
- Included Windows.h in threads.h
 2014-05-05 11:18:43 +03:00

Laurent Fasnacht 212d390003 Cleanup of encoder_state_init and encoder_state_finalize 2014-05-01 11:16:10 +02:00
Laurent Fasnacht 161053f86b Do not allow more tiles than dimension in LCU 2014-05-01 07:11:31 +02:00
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
  substream_encode.

- Remove use of yuv_t from encode_one_frame, as it's not used there anymore.
 2014-04-30 11:15:34 +03:00
Ari Koivula d808fe3b02 Merge branch 'strategy_selector' 2014-04-29 15:36:48 +03:00
Ari Koivula bd7e021742 Modify strategyselector to work with VS2010. 
- VS doesn't have snprintf.

- VS doesn't support GCC attributes.

- Add defines for __SSE__ and __SSE2__ on VS.
 2014-04-29 15:29:06 +03:00
Laurent Fasnacht bf7e755cf7 Strategies and runtime detection/choice of best algorithm 2014-04-29 11:51:41 +02:00
Ari Koivula 27b94d4b45 Address gcc -Wtype-limits errors. 
- Fixes warnings in #19 and #16.
 2014-04-29 09:15:52 +03:00
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

- 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.

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.

- 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).

Ari Koivula c968253eb3 Estimate SAO merge coding costs better. 
- This doesn't seem to have very much of an effect. I guess the difference

 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.

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.

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.

 2014-04-09 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

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

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.

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.

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.

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.
