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 43ae0a3b9a Implemented RDO cost calculation to Intra modes 2014-04-10 10:25:20 +03:00
Marko Viitanen c38ec1aa10 Added commandline option for RDO (--rd) 2014-04-09 12:29:15 +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.

Marko Viitanen 234b6ed48c Merge commit 'e15a86268def51984b2ff4efc966ddfa74ca3fa2' 2014-04-04 16:07:57 +03:00
Marko Viitanen e15a86268d Clean up tabs and whitespaces 2014-04-04 16:04:44 +03:00
Laurent Fasnacht 816ae13b1d Moved context information inside cabac_data. 
This is required in order to be able to work on parallelism.
 2014-04-04 14:28:50 +02:00
Laurent Fasnacht 8a14bd3b7b Remove cabac global variable 2014-04-04 14:26:40 +02:00
Laurent Fasnacht 946c815932 init_context directly has a QP parameter, instead of passing an encoder_control* 
This makes context less tightly coupled with encoder.
 2014-04-04 14:26:39 +02:00
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 14:26:39 +02:00
Marko Viitanen 7484dafd82 Fix for get_coeff_cost() scan mode selection 
Small BD-rate improvement with this fix

Marko Viitanen b09854d964 Implemented RDO function to calculate bits used for coefficient coding 2014-04-04 13:09:42 +03:00
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.
 2014-04-04 13:02:09 +03:00
Ari Koivula 61256fc31a Enable -Wall by default. 2014-04-04 13:02:08 +03:00
Ari Koivula 69ac9176a5 Disable warnings for extras/getopt. 
- This isn't our code so we don't care about these warnings.
 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.
 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.
 2014-04-04 13:02:06 +03:00
Ari Koivula 61ae195af7 Resolve warnings about assignments within conditions. 
- Working towards issue #11.
 2014-04-04 13:02:06 +03:00
Ari Koivula d44d1837bb Remove unreferenced parameters. 
- Working towards issue #11.
 2014-04-04 12:56:24 +03:00
Ari Koivula 46d33d3945 Resolve unsigned/signed mismatch warnings. 
- Working towards issue #11.
 2014-04-04 12:56:23 +03:00
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.
 2014-04-04 12:56:22 +03:00
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.
 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.
 2014-04-03 15:38:17 +03:00
Ari Koivula f380e7d4b0 Check for malloc failure. 2014-04-03 15:38:17 +03:00
Ari Koivula 313466fdff Remove unused variables. 
- Working towards issue #11.

- Either removed or redefined variables to not cause a warning.
 2014-04-03 15:37:59 +03:00
Marko Viitanen 0da8071300 Changed final cost (and transform skip) error function from SAD to SSD 2014-04-02 14:51:39 +03:00
Marko Viitanen a14fb14e33 Added new commandline parameter --no-transform-skip 2014-04-02 14:49:48 +03:00
Marko Viitanen 21e02e2d7d Added 4x4 SATD (Hadamard) 
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.
 2014-04-02 10:54:03 +03:00
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
 2014-03-25 11:46:56 +02:00
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.
 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.
