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 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 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.

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.

Marko Viitanen b83559d3f3 Use RDO to check for transform skip mode 2014-04-04 13:09:42 +03:00
Ari Koivula b19e4f3f2d Resolve possible uninitialized variable warnings. 
- Working towards issue #11.

- Neither variable was actually used as uninitialized.

Ari Koivula 46d33d3945 Resolve unsigned/signed mismatch warnings. 
- Working towards issue #11.
 2014-04-04 12:56:23 +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
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 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
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 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 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 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 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
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.
 2014-03-14 16:56:49 +02:00
Ari Koivula e93ae54e70 Fix bug with selecting wrong coeff scan mode for 4x4 blocks. 2014-03-12 14:56:05 +02:00
Ari Koivula 409b094acf Try and get NxN to work again. 
- Moved NxN search to be done on the same level as other searches, as it's
  really not any different from 2Nx2N.
- Produces working bitstream but reconstruction is different.

Ari Koivula 1cf03cfb37 Add --no-rdoq parameter. 2014-03-05 17:02:21 +02:00
Ari Koivula ca51f660d5 Fix fluctuation of coefficients on identical frames when RDOQ is on. 
Moves CABAC context initialization to take place before search. This fixes
an issue with RDOQ returning different coefficients for identical adjacent
frames.

- This actually probably worsens BD-rate a little for all frames except the
  first one because we were using last frames final CABAC context for every
  LCU and now we are using initialized CABAC contexts. The fix is to encode
  the LCU before we start compressing the next LCU so we can update CABAC
  contexts.

Marko Viitanen 9968fd46b0 Fixed chroma array index calculations in transform_tree() and intra_recon_lcu() 2014-02-27 16:42:32 +02:00
Ari Koivula 5f75753f85 Set coeff flags correctly. 
The coeff flags are no longer propagated upwards because encode_transform_tree
is being called from depth > 0. The fix is to initialize the whole coeff flag
array when the coeff flag is set.

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 241aa9155c Fixed crash-bug when using NxN Intra mode (array index overflow) 
In NxN mode, chroma predictions were pushed to buffer when chroma should not have been used at all. (Because it is processed only on first of the four NxN luma blocks)

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.

Conflicts:

- 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.
 2014-01-29 17:04:41 +02:00
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

- Disable SAO and deblocking to be able to see problems with reconstruction better.
 2014-01-29 14:18:01 +02:00

Ari Koivula a38a5fd647 Improve transform tree coding. 
- 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.
 2014-01-14 18:39:24 +02:00
Ari Koivula d5745aa31a Fix encode_transform_tree to handle 4x4 luma. 
- Add room to cu_data.coeff_top_yuv arrays for the 4x4 PUs data. Will probably have to do the same to other coeff flags. The flags could also probably be combined as they are a bit redundant.
 2014-01-13 18:37:47 +02:00
Ari Koivula 73fdc35c4f Try to implement 4x4 luma transform coding.

Ari Koivula a57b938270 Add new module sao. 
- Move sao-stuff not directly related to encoding to sao-module.
- Calculate sao for all LCUs before encoding any of them. This is in
  preparation to doing the reconstruction line at a time instead of
  LCU at a time.
 2013-11-04 19:41:01 +02:00
Ari Koivula 03f2967899 Block based sao dead end. 
This will never work because the adjacent blocks require the original values

Ari Koivula 116d5b14be Fix handling of non factor of 8 resolution. 
- Reimplement bit filling routines to copy bits form the edge, instead of
  using a constant.

- Add real_width and real_height to encoder_input and store the actual input
  resolution in them instead of in encoder_input.width and height. This fixed
  a crash. It's also clearer.

- Correctly scale conf_win offsets to be in terms of chroma.
