Marko Viitanen 5f79f30b8c Added preliminary support for multiple reference frames 
L0 reference list is being updated and sent to bitstream but actual usage of other than default reference might break something.
 2014-02-10 11:32:48 +02:00
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)
 2014-02-07 17:24:58 +02:00
Marko Viitanen d106b21954 Removed redundant function call from encode_block_residual()

  anywhere else.

- Working towards issue #11.
- Change lambda cost multiplier for intra NxN to from 256 to 4.
- Add 0.5 to the lambda multipliers so it's rounded instead of truncated.
 2014-02-06 11:04:23 +02:00
Ari Koivula 1d730bd248 Update usage information and version string. 
- Change stderr back to text mode. Can't see what harm it should allow us to print
  correct newlines for different platforms.
- Remove copy-pasted function calls from usage printing.
 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.

Marko Viitanen 337a565232 Better lambda cost implementation (from HM12) 
- Lambda array changed to double as in HM

Marko Viitanen 39a45936a6 Fixed crash bug on QP < 15 caused by division with zero lambda cost 2014-02-04 09:39:27 +02:00
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.

Yusuke Nakamura 4ffdb358ed nal: Add the writing of an additional zero_byte before the start code. 
Enables the output of spec-compliant byte streams, as the specification
notes that an additional zero_byte has to be added under certain
circuimstances.

 2014-01-31 17:17:44 +02:00
Marko Viitanen ac8141b328 Fixed a bug in intra search and some memory leaks, changed version to 0.2.1 
Intra search was using faulty border data and selected modes were a bit random. Around -0.5% (LP) and -2% (AI) change in BD-rate was seen in limited testing conditions.

Marko Viitanen 76f24408b6 Included x264asm abstraction layer -library and fixed Makefile 
Name mangling is causing problems on different platforms (issues #2 and #3) and some of it was solved modifying the Makefile. Separate 32bit and 64bit assembly functions were also causing problems and since we were going to move to x264asm abstraction layer anyway, we decided to do it now before spending time on the old implementation.

Ari Koivula 5d12706510 Merge branch 'intra_NxN' 
Conflicts:
	src/encoder.c

- 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. 
- The NxN coefficients were being saved to the bottom right PU offset instead of
  the parent CU offset.
- Re-enable coefficient coding for chroma NxN.
 2014-01-29 14:22:31 +02:00
Ari Koivula f1b2e9f603 Fix buggy chroma when NxN is present. 
- NxN intra prediction seems to work fully now.
- Coefficients still don't work for NxN.
 2014-01-29 14:22:31 +02:00
Ari Koivula 9f855c16db Fix building of reference border in the bottom of the frame. 
- Don't write to the top-left corner during construction of left border,
  because that is handled later that is handled later.
 2014-01-29 14:22:31 +02:00
Ari Koivula ca454b67df Fix intra filtering for 4x4 luma blocks. 2014-01-29 14:22:31 +02:00
Ari Koivula acbe656c6d Fix intra prediction mode list generation. 2014-01-29 14:22:30 +02:00
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. 
- Set part-size for Inter.
- Change to Intra Only mode for testing.
- Many small changes here and there. Should have been separate commits probably, but too late.
- Disable SAO and deblocking to be able to see problems with reconstruction better.
 2014-01-29 14:18:01 +02:00
Ari Koivula 5e2f22f447 Try to fix intra prediction mode coding for NxN. 
- Adjust predictor list to take modes from PUs in addition to 2Nx2N CUs.
- Change intra_get_dir_luma_predictor to take PU index instead of CU index.
- Comment prediction encoding now that I've had to look it up.

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. 
- Doesn't work yet so it's disabled.

Should work exactly the same, but with the prediction mode selection done
separately from the binarization it's easier to see that the implementation
is correct.
