Laurent Fasnacht 52ae027b3a Avoid undefined behavior in memcpy calls 
"The memcpy() function shall copy n bytes from the object pointed to by s2 into the object pointed to by s1. If copying takes place between objects that overlap, the behavior is undefined."

Ari Koivula 29787efbbc Fix whitespace. 
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.
 2014-04-11 16:50:59 +03:00
Ari Koivula 115872b300 Add total running time to output. 2014-04-11 12:42:37 +03:00
Marko Viitanen de1c0b7e8d Fixed intra RDO to include mode bitcost 2014-04-10 16:28:41 +03:00
Marko Viitanen a657cf84d9 Insert most probable (predicted) intra modes to RDO search 2014-04-10 15:59:36 +03:00
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.
 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 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

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

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.
