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.

Ari Koivula e4b942ad67 Enable /W4 for VS.
- Disabled errors are:
 - Implicit conversion from bigger to a smaller type. I don't want to disable
   it but there are still about 60 of these and adding explicit C casts
   everywhere is just going to cause more problems.
 - Nonstandard extension: Non-constant aggregate initializer.
 - Translation unit is empty.

Ari Koivula 69ac9176a5 Disable warnings for extras/getopt.
- This isn't our code so we don't care about these warnings.

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.
2014-04-04 13:02:07 +03:00
Ari Koivula b19e4f3f2d Resolve possible uninitialized variable warnings.
- Working towards issue #11.

- Neither variable was actually used as uninitialized.

Ari Koivula c142cbba21 Fix typo.
- Obvious typo. This g_bitdepth - 8 used to be g_bitincrement. Doesn't affect
  anything yet as we don't actually support bitdepth > 8 yet.

Marko Viitanen 5bebb34787 Merge pull request #22 from lfasnacht/realloc_fix
Use realloc correctly
2014-04-04 08:28:15 +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 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.

- Working towards issue #11.

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

Taken from HM 13.0
2014-04-02 11:12:42 +03:00
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.

Marko Viitanen b9f8950cf7 Merge pull request #21 from lfasnacht/global-h-rewrite
Improved clarity of src/global.h
2014-04-01 15:15:00 +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

Ari Koivula 5d50872ab3 Merge branch 'lcu-encoding' 2014-03-21 16:46:02 +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.

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.

The copy up and down functions had wrong max depth so they didn't work with
4x4 blocks.
