- 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.
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.
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.
Enables the output of spec-compliant byte streams, as the specification
notes that an additional zero_byte has to be added under certain
circuimstances.
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.
- 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.
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.
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.
- 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)
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.
