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.

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 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
