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

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.

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.

Laurent Fasnacht 1e03cf8ac1 Add a function to free g_exp_table. 
Even though g_exp_table has to be global (used in #define), it's better to avoid requiring other module to directly access it.

 2014-04-04 13:02:08 +03:00
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
  statements so I removed that aspect, which also has the minor benefit of not
  requiring the starting if (0) statement.

  anything yet as we don't actually support bitdepth > 8 yet.
 2014-04-04 12:56:22 +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.
 2014-04-04 06:37:35 +02:00
Ari Koivula 0074cd1a98 Add extra parenthesis to suppress compiler warnings. 2014-04-03 15:38:18 +03:00
Ari Koivula 27a3329dfb Remove unreferenced_parameter macro. 
- It was a silly hack to selectively silence compiler warnings from VS, but
  there is no point as it causes compiler warnings in GCC.

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.
 2014-04-02 10:54:03 +03:00
Laurent Fasnacht ae5c573843 Global defines are now documented with references the specification when possible. Removes some redundancy. 2014-04-01 13:48:17 +02:00
Panu Sjövall c8f629495d Remove unnecessary buffer from bitstream. 
- Writing encoded data to file is done in bitstream_put one byte at a time and nal_write only writes the packet headers
 2014-03-25 11:46:56 +02:00
Ari Koivula 953aef0379 Move rest of LCU encoding inside the LCU loop. 
- Move SAO search inside the LCU loop.

- Move CU coding inside the LCU loop.

- Move SAO frame reconstruction loop to sao module.
 2014-03-21 12:41:44 +02:00
Ari Koivula 746eaa3671 Move deblocking code to filter module. 2014-03-21 11:57:12 +02:00
Ari Koivula 4d34377c42 Clean up deblocking code a bit. 
- Change guards to use the same method of checking for coordinate alignment.

- Move variables to reduce their scope.
 2014-03-21 10:50:47 +02:00
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.
 2014-03-19 16:01:30 +02:00
Ari Koivula eacad83ff9 Fix encoder reconstruction output for non multiple of 8 sized input. 
Output changed so that only pixels within the conformance window are output.
 2014-03-19 13:24:01 +02:00
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. 
- As we move to per-LCU encoding only search_lcu will be necessary.

- Function search_best_mode is no longer used.
 2014-03-17 18:04:41 +02:00
Marko Viitanen c7ee176480 Removed unused function search_best_mode() 2014-03-17 12:56:04 +02:00
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.

Ari Koivula aa59605392 Set correct max depth for search work-tree copying. 
The copy up and down functions had wrong max depth so they didn't work with
4x4 blocks.
 2014-03-12 14:02:13 +02:00
Marko Viitanen b5756821dd Tuned cost calculations for "final cost" 
By adding chroma cost and using 1.5x coeff cost instead of 0.5x, additional 3% (LP) and 1.8% (AI) drop in BD-rate noticed.
 2014-03-12 10:35:56 +02:00
Ari Koivula 409b094acf Try and get NxN to work again. 
- Moved NxN search to be done on the same level as other searches, as it's
  really not any different from 2Nx2N.
- Produces working bitstream but reconstruction is different.
 2014-03-11 19:19:20 +02:00
Marko Viitanen 75dd1f48ef Bugfix: calculate "final cost" only when block is inter or intra 2014-03-11 17:09:08 +02:00

Ari Koivula 7e507fd615 Add --input-res CLI parameter. 
- Also set default width and height to 0 because it makes no sense to assume
  dimensions. It's kind of like defaulting to the most common altitude when
  the altimeter is broken.
- Add config_validate to have a place for checks on overall cfg state.
 2014-03-10 16:09:33 +02:00
Ari Koivula a644848b36 Add --seek CLI parameter. 
Related to issue #12.

Motivation for adding this is that the syntax for frame accurate seeking in
ffmpeg is a little cumbersome. Also it's kind of a standard feature I guess.

Ari Koivula ca51f660d5 Fix fluctuation of coefficients on identical frames when RDOQ is on. 
Moves CABAC context initialization to take place before search. This fixes
an issue with RDOQ returning different coefficients for identical adjacent
frames.

- This actually probably worsens BD-rate a little for all frames except the
  first one because we were using last frames final CABAC context for every
  LCU and now we are using initialized CABAC contexts. The fix is to encode
  the LCU before we start compressing the next LCU so we can update CABAC
  contexts.

Ari Koivula 5f75753f85 Set coeff flags correctly. 
The coeff flags are no longer propagated upwards because encode_transform_tree
is being called from depth > 0. The fix is to initialize the whole coeff flag
array when the coeff flag is set.
