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.

Ari Koivula 8c42054f4c Merge branch 'greatest' 2014-01-31 16:21:35 +02:00
Ari Koivula 6b4d113feb Replace seatest with greatest as a framework for unit tests.
- Add our own Github fork of greatest as a submodule, in case we want to
  improve it and push changes upstream easily in the future.
- Update existing unit tests to use greatest.
- Update Visual Studio project to remove traces of seatest and include greatest.

Marko Viitanen 70ab90f637 Merge pull request #4 from jeeb/stdin_and_gitignore
Two minor additions

Ari Koivula 7d5c3f7d0f Rename sad_tests.cpp to sad_tests.c. 2014-01-31 14:36:50 +02:00
Jan Ekström f9a3d40b48 gitignore: Add object files to the list of ignored files
Running the Makefile outside bin or build leads to creation of
these files in a place that does not get ignored.

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.

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.

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.
