This tool is a gadget for offline probability training.
A binary executable aom_entropy_optimizer will be generated in
tools/. It parses a binary file consisting of counts written in
the format of FRAME_COUNTS in entropymode.h, and computes the
optimized probability table, which will be written to a new c file
optimized_probs.c using the format in entropymode.c.
Command line:
./aom_entropy_optimizer [directory of the count file]
The input file can be either be generated from a single run by
turning on entropy_stats experiment(counts are accumulated from
frame to frame, and finally written to counts.stt), or be collected
at a larger scale, at which a python script (will be provided soon)
can be used to aggregate multiple stats output.
Optimization for initial CDFs will be also supported later.

The new_tokenset experiment replaces the unconstrained tokenset with a
multisymbol alphabet in an inventive way.
Tested configurations:
new_tokenset + ec_adapt, new_tokenset, ec_multisymbol

Zero, one, and two or more coded as one symbol (head).
Remaining tokens coded as a tail symbol.
The pareto CDF distribution is adjusted to cover tokens from
two onwards.

The code that generates the raw distribution is based on a MATLAB
program by Debargha Mukherjee, and the algorithm used to quantize the
distribution comes from the ANS Toolkit by Jarek Duda.

git diff adds the following line to diffs:
\ No newline at end of file
which interferes with diff.py parsing. diff.py only looks for '+', '-'
and ' ' at the beginning of the line.

Creates a merge between the master and experimental branches. Fixes a
number of conflicts in the build system to allow *either* VP8 or VP9
to be built. Specifically either:
$ configure --disable-vp9 $ configure --disable-vp8
--disable-unit-tests
VP9 still exports its symbols and files as VP8, so that will be
resolved in the next commit.
Unit tests are broken in VP9, but this isn't a new issue. They are
fixed upstream on origin/experimental as of this writing, but rebasing
this merge proved difficult, so will tackle that in a second merge
commit.

When run with no arguments, report warnings in the diff between the
working tree and HEAD. With arguments, report warnings in the diff
between the named commit and its parents.

Prior to this patch, if there were any lint errors, this script would
exit with an error, even if those errors were not in the hunks being
tested by this script. This change makes it so that if any lint lines
are printed, an error is returned.

truncate() operates from the current file pointer position. On at least
Linux specifying 0 without resetting the pointer will pad the file with
zeros to the current offset.

It's common for commit messages to be wrapped at odd places. git-gui
is often to blame. Adds support for automatically fixing up these
messages if running ftfy --amend, and adds a new option --msg-only for
fixing only the commit message.

This is a utility for applying a limited amount of style correction on
a change-by-change basis. Rather than a big-bang reformatting, this
tool attempts to only correct the style in diff hunks that you touch.
This should make the cosmetic changes small enough that we can mix them
with functional changes without destroying the diffs, and there's an
escape hatch for separating the reformatting to a second commit for
purists and cases where it hurts readability.
At this time, the script requires a clean working tree, so run it after
you've commited your changes. Run without arguments, the style
corrections will be applied and left unstaged in your working copy. It
also supports the --amend option, which will automatically amend your
HEAD with the corrected style, and --commit, which will create a new
change dependent on your HEAD that contains only the whitespace changes.
There are a number of ways this could be applied in an automated manner
if this proves to be useful, either on a project-wide or per-user
basis. This doesn't buy anything in terms of real code quality, the
intent here would be to keep formatting nits out of review comments in
favor of more meaningful ones and help people whose habitual style
doesn't match the baseline.
Requires astyle[1] 1.24 or newer.

This information is in git, so it's better to use that as a source than
updating this file manually. This script can be run manually at release
time for now, or we can set up a cron job sometime in the future.
