Marko Viitanen 362fc6c5a5 Reduced bit cost when skip mode is selected 2014-03-12 14:13:38 +02:00
Ari Koivula aa59605392 Set correct max depth for search work-tree copying. 
The copy up and down functions had wrong max depth so they didn't work with
4x4 blocks.
 2014-03-12 14:02:13 +02:00
Marko Viitanen b5756821dd Tuned cost calculations for "final cost" 
By adding chroma cost and using 1.5x coeff cost instead of 0.5x, additional 3% (LP) and 1.8% (AI) drop in BD-rate noticed.
 2014-03-12 10:35:56 +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.
 2014-03-11 19:19:20 +02:00
Marko Viitanen 75dd1f48ef Bugfix: calculate "final cost" only when block is inter or intra 2014-03-11 17:09:08 +02:00
Marko Viitanen 3b59d7c3a3 Implemented "final cost" calculation for best CU on each depth in search 
Take SAD between reconstruction and original and add cost from coding and cost for coding coefficients.
 2014-03-11 15:01:50 +02:00
Marko Viitanen aa0fb6ccad Store intra coding bit costs to CU structure 2014-03-11 12:15:50 +02:00
Marko Viitanen bdf8166e5c Store inter coding bit costs to CU structure 
To be used for calculating better coding cost later
 2014-03-11 11:40:39 +02:00
Marko Viitanen d2d877933a bugfix: only fclose recout if it was opened 2014-03-11 09:09:43 +02:00
Marko Viitanen eaf4434ae9 Removed unused parameter cur_cu from inter_get_merge_cand() 2014-03-11 09:04:17 +02:00
Marko Viitanen f2e722fed8 Implemented early search termination when skip mode is used 2014-03-11 08:55:38 +02:00
Ari Koivula 1b2705a042 Add video dimensions to the filename of encoder reconstruction. 2014-03-10 18:10:50 +02:00
Ari Koivula 965d8c377a Make encoder reconstruction obey --debug. 2014-03-10 18:10:49 +02:00
Ari Koivula 7e507fd615 Add --input-res CLI parameter. 
- Also set default width and height to 0 because it makes no sense to assume
  dimensions. It's kind of like defaulting to the most common altitude when
  the altimeter is broken.
- Add config_validate to have a place for checks on overall cfg state.
 2014-03-10 16:09:33 +02:00
Ari Koivula a644848b36 Add --seek CLI parameter. 
Related to issue #12.

Motivation for adding this is that the syntax for frame accurate seeking in
ffmpeg is a little cumbersome. Also it's kind of a standard feature I guess.
 2014-03-10 15:14:56 +02:00
Marko Viitanen a935aa5d96 Untabified encmain.c and nal.c 2014-03-10 12:10:40 +02:00

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.
 2014-03-05 17:02:13 +02:00

Ari Koivula 5f75753f85 Set coeff flags correctly. 
The coeff flags are no longer propagated upwards because encode_transform_tree

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.

 2014-02-05 19:16:44 +02:00
Ari Koivula 355340067f Modify search_tree to take a pixel coordinate instead of CU coordinate. 
I need at least 4x4 resolution for NxN. It's simpler to just use pixel
coordinates.
 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.

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
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.
 2014-01-29 14:22:30 +02:00
Ari Koivula 71a996f50f Work on reconstruction and searching.

- 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.

Ari Koivula c0f06fdb9e Change intra prediction to use SAD instead of SATD. 
Inter uses only SAD and we don't have mechanisms for comparing these two.

Ari Koivula c7ca3a6b44 Clarify parameter passing for hexagon_search. 
Handling mv as a local struct instead of pointer had no performance impact,
but it makes the parameter passing clearer so I'm keeping it.
