Ari Koivula b067b2f802 Add lcu_t initialization. 2014-02-26 10:58:20 +02:00
Ari Koivula 7e520a85c4 Add skeleton/plan for LCU based search. 
The plan is to replace the dumb search we are doing now with proper sequential
search that is encapsulated inside data structure that holds all temporary
search data for the LCU.

Marko Viitanen d2b8f50351 Merge branch 'master' of https://github.com/lu-zero/kvazaar 2014-02-25 10:53:51 +02:00
Marko Viitanen 565be069b9 Implemented proper intra mode cost calculation 
This does not currently affect the search primary search defining the used block sizes, only the refining second intra search. Gain 1.9% BD-rate on All Intra 600f of BQMall QP 22,27,32,37.

Merge check is now performed in a function to ease the checking
 2014-02-21 15:54:56 +02:00

Ari Koivula 5760c79272 Fix crash with dimensions that are not multiples of 8. 
The clean up of input parsing and encoder initialization code had caused the
real source input dimensions to be used for array initialization, instead of
the dimensions modified to be multiples of the smallest coding unit.
 2014-02-21 12:48:33 +02:00
Marko Viitanen 13dc95a164 Implemented band SAO reconstruction 2014-02-21 11:52:41 +02:00

Marko Viitanen 5d946c774a Implemented draft SAO band offset functions 2014-02-20 16:08:09 +02:00
Marko Viitanen bb1ae0da62 Limited maximum number of reference frames to 15 
This now complies with the specification (when using only L0 reference list)
 2014-02-20 11:09:09 +02:00
Ari Koivula 18c3d9c72d Add scons build script. 
We will also maintain the Makefile for basic building. This is for more
complicated stuff, like building the project on command line with
Visual Studio.
 2014-02-19 16:58:52 +02:00
Marko Viitanen db689227f4 Increased maximum ref frame count to 16 and set default to 3 2014-02-19 15:09:17 +02:00
Marko Viitanen c230a73155 Added number of reference frames to prefix SEI user data 2014-02-19 14:45:18 +02:00
Marko Viitanen 8490ff1a9d Disabled NxN mode 
Something must be done to enable better selection of NxN blocks in order to gain BD-rate with this mode.
 2014-02-19 14:36:17 +02:00
Marko Viitanen 3618eab72a Added lambda cost when using reference frames with refIdx > 0 
Because selecting references "far away" costs bits, this should help with the issue that multiple reference frames actually increases coded bits with no quality gain.
 2014-02-19 14:34:36 +02:00
Marko Viitanen 478552ea00 Added commandline parameter for reference frame number 
Also updated README and usage with the new parameter

motion vector candidates are not yet scaled or selected correctly
 2014-02-17 09:58:10 +02:00
Marko Viitanen 28aa20df12 Basic search for multiple reference frames 2014-02-17 09:58:10 +02:00
Ari Koivula 8e63dd29bb Fix compiler warnings for VS2010 /W4 in intra.c. 
- Working towards issue #11.
- Removed intra_get_block_mode as unused.
- Removed unused parameters from functions. Many of them were remnants from
  earlier data structures and earlier features of HEVC that have been removed.
- Lots of implicit conversions from larger types to smaller ones. I tried to
  avoid turning all of them to explicit ones this time and opted for changing
  the original data type instead. Had to do it in few cases though to stop the
  changes from propagating too widely.

Marko Viitanen a6e8373349 Fixed crash issue on windows when cqmfile was not specified 
fclose(cqmfile) crashed on windows when cqmfile was NULL
 2014-02-14 14:38:53 +02:00
Yusuke Nakamura a860bbc7f9 config: Add --cqmfile to use custom quantization matrices from a file. 
The coefficients in a matrix are stored in up-right diagonal order.

The following indicates the default matrices specified in the spec.

The intent was to remove the flag that enabled intra in inter frames, as that
is not really that usefull anymore, but it ended up disabling intra instead.

 2014-02-05 18:43:34 +02:00
Ari Koivula ea312082a4 Simplify the prediction mode search recursion. 
No need to be so clever for something this simple.

I moved the cost initialization outside the recursing function because it
relied on the clever recursion to work. It should eventually be moved to its
own function that also initializes all the other fields just to be safe. I
didn't do that yet because I want to do it per-LCU and these functions are
still working on per-frame basis.

Ari Koivula 7bb9c25447 Remove duplicate implementation of intra_build_reference_border. 
The search_buildReferenceBorder was an ugly hack and a place for bugs to hide
that should never have existed. Now it doesn't.

The change reduces PSNR a little, but also reduces the bitrate, when the
expected result was to have no change in either. I'm guessing there was still
some bug in the search_buildReferenceBorder, but the bug could also be in
intra_build_reference_border. Will have to do more testing to be sure, but
having one place to look at will be better than having two.

- Chroma RDOQ changes conflicted because I had moved the chroma
  quantization/dequantization to it's own function.
- Merged to master because I want my code to show up in github. =)
  All the old stuff still works, even though NxN doesn't work, so there
  is no reason not to merge anyway.

Ari Koivula e33655fde5 Remove debug stuff and disable intra NxN in preparation for a merge. 
- Re-enable intra search based on reconstructed image.
  - This didn't have as much of an effect as I thought it would.
- Re-enable SAO and deblocking.
- Disable NxN searching. (4x4 luma coding is still broken)
 2014-01-29 16:45:37 +02:00
Ari Koivula bf80007270 Try to fix 4x4 luma coding. 
Still doesn't work. I have no idea what the problem is. Probably somehow related to the coefficient coding, since the bitstream seems to work, the prediction is correct and the error is not very severe.

- Change scan order selection to be more verbose and based on the correct mode for 4x4. Didn't affect the problem with 4x4 luma in any way although it should have.
- Re-enable residual coding as everything seems to work now besides 4x4 luma.
 2014-01-29 15:09:41 +02:00
Ari Koivula de3c58862a Fix intra NxN chroma coefficients.

Ari Koivula 81b51f17d8 Reimplement intra_build_reference_border to support NxN. 
New implementation uses precalculated tables to look up number of reference
pixels available in coded CUs. Otherwise it works just like the previous
version.

- NxN mostly works. Prediction appears to be almost correct but there is a
  slight error in the exact values, probably related to filtering.

- Clean up code and comment.
- Change terminology to match H.265 specification where possible.
- Move transform splitting for depth==0 out of the coding part. It's not
  possible to do it here anyway because intra reconstruction is different
  if the transform is split.
- Add checking for transform hierarchy depth when coding split flag.
- Fixes bug with cu_data.tr_depth being set. The CU struct was being reused
  for inter coded CUs, which did not initialize the tr_depth.

separately from the binarization it's easier to see that the implementation
is correct.
