- Vectors that point far outside the frame don't work, although the special
case of them pointing right beside the frame works. So test for vectors
pointing farther away.
- Update include directory for greatest.
- Working towards issue #11.
- Moved all const arrays from .h to the .c. These are not used anywhere else.
- Moved entropy_bits array and its helper macro to rdo.c. They are not used
anywhere else.
- Implicit conversions to explicit ones.
- 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.
- 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.
