Local variable offsets are now consistent for the functions,
removed unused parameters, reworked the assembly to eliminate
stalls/instructions.

Failed to build on Linux (as described in Android.mk) with NDK r7b.
Set vpx_rtcd.h dependency after libvpx sources are added to
LOCAL_SRC_FILES so that vpx_rtcd.h is generated before any libvpx file
is touched.

This patch includes:
1. fixes to disable block based termporal mixing when motion
is detected (because this version of mfqe only handles zero motion).
2. The criterion used for determining whether to mix or
not are changed to use squared differences rather than
absolute differences.
3. Additional checks on color mismatch and excessive block
flatness added. If the block as decoded has very low activity
it is unlikely to yield benefits for mixing.

In cases where you have a flat background occluded by a moving object
of similar luminosity in the foreground, it was likely that the
foreground blocks would persist for a few frames after the background
is uncovered. This is particularly noticable when the object has a
different color than the background, so add the chroma planes in as an
additional check.
In addition, for block sizes of 8 and 16, the luma threshold is
applied on four subblocks independently, which helps when only part of
the background in the block has been uncovered.
This fixes issue #392, which includes a test clip to reproduce the
issue.

When using 'make dist' after --disable-vp8[encoder|decoder] it would
fail to recognize the option. This would only occur when also specifying
--enable-install-docs and --enable-install-srcs but not
--enable-codec-srcs
Including vpx/ fixes builds with --enable-codec-srcs
vpx_timer.h is also required for vpxenc.c

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.

Reduced the size of the struct by 8 bytes, which would be
a memory savings of 64800 bytes for 1080 resolutions. Had
an extra byte, so created an is_4x4 for B_PRED or SPLITMV
modes. This simplified the mode checks in
vp8_reset_mb_tokens_context and vp8_decode_mb_tokens.

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 new vp8_decode_mb_tokens() uses a modified version of
WebP's GetCoeffs function. For now, the dequant does not
occur in GetCoeffs.
Tests showed performance improvements up to 2.5% depending
on material.

Adds logic to disable mfqe for the first frame after a configuration
change such as change in resolution. Also adds some missing

This change added a motion search skipping mechanism similar
to what we did in second pass. For a macroblock that is very
similar to the macroblock at same location on last frame,
we can set its mv to be zero, and skip motion search. This
improves first-pass performance for slide shows and video
conferencing clips with a slight PSNR loss.

Newer XCodes have moved the SDK path from /Developer/SDKs
Use a suggestion from jorgenisaksson@gmail.com to locate it
osx_sdk_dir is not required to be set. Apple now offers a set
command line tools which do not require this. isysroot is also
not required in newer versions of XCode so only set it when we
are confident in the location.
There remain issues with the iOS configure steps which will be
addressed later

This issue likely doesn't appear in the unmodified encoder, but
sufficient hacking on the mode selection loop can expose it.
