Jan Ekström 271c08f963 config: Add a string copying helper function 
Removes the need to add the same code into multiple places
 2014-01-31 17:24:04 +02:00
Jan Ekström d8d44e5bcd encoder: Remove a non-UTF-8 symbol from the code 
Silences a Visual Studio warning on systems where the symbol is not
in the local code page

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.

Jan Ekström f1ff6a8274 encmain: Add rudimentary support for input via stdin 2014-01-31 14:32:41 +02:00
Marko Viitanen 80da15df4d Adjusted cost calculation of CU split 
Quick testing shows BD-rate change of -14% (LP) and -4% (AI) with 600 frames of BQMall using QP 22,27,32,37.

Marko Viitanen 5d5fbb8704 Added commandline configuration of intra period (-p <intra_period>) 2014-01-31 10:23:56 +02:00
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 b93629f26e Re-enable P frames. 
It was inadvertently disabled due to an aborted merge.

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.

Just a simple copy and paste with minimal changes.
 2014-01-15 16:55:05 +02:00
Ari Koivula 35ba873abc Move transform unit coding to its own function. 2014-01-14 18:47:02 +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. 
- Doesn't work yet so it's disabled.
- Change encode_transform_coeff to accept PU (Prediction Unit) coordinates
  instead of CU coordinates because CUs are 8x8.

Ari Koivula 553bcdc324 Rewrite intra prediction mode coding to be simpler. 
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.
 2013-12-18 14:16:04 +02:00
Ari Koivula cf0d314d03 Clean up prediction mode coding. 
This was done as preparation for adding NxN intra.

- Move sao-stuff not directly related to encoding to sao-module.
- Calculate sao for all LCUs before encoding any of them. This is in

  LCU at a time.

Ari Koivula 03f2967899 Block based sao dead end.

Ari Koivula 36fe88caef Fix rounding errors in chrome half pel prediction. 
The spec speaks nothing about rounding these values, but HM12 rounds the final
values. HM might be based on an old version of the spec that does all this rounding and clipping.

- Also fixes erroneous indexing when both horizontal and vertical are half pel.

Ari Koivula 681975ad4b Fix inter reconstruction for 8x8 blocks and enable 8x8 inter blocks again. 
Inter reconstruction was modifying the movement in place when it shouldn't
have. This was causing issues only for the 8x8 blocks, because for larger
blocks the modified movement vector was too far away to be seen by the blocks
below it.
