8542f9c4f1 replaygain: correctly parse peak values
According to the ReplayGain spec, the peak amplitude may overflow and may result
in peak amplitude values greater than 1.0 with psychoacoustically coded audio,
such as MP3. Fully compliant decoders must allow peak overflows.

Additionally, having peak values in the 0<->UINT32_MAX scale makes it more
difficult for applications to actually use the peak values (e.g. when
implementing clipping prevention) since values have to be rescaled down.

This patch corrects the peak parsing by removing the rescaling of the decoded
values between 0 and UINT32_MAX and the 1.0 upper limit.

16509d3a28 log: allow color highlighting in Cygwin's mintty
Configure will detect the availability of the Windows' console functions and set
HAVE_SETCONSOLETEXTATTRIBUTE.  Meaning av_log will use those functions to
control colours.  When ffmpeg is run in Cygwin's mintty terminal emulator it
will not use colour highlighting in this case.

Mintty responds to the usual escape code colours (it even supports 256 colours).
Windows' cmd.exe does not.  Fortunately it seems that Cygwin's emulation layer
now translates the basic 16 colours into Windows' Console command functions.

That means that we can have av_log use the standard colour commands and let
ffmpeg print colours in both mintty and cmd.

Not guaranteed to be in nanosecond resolution. On iOS 7 the duration
of one tick is 125/3 ns which is still more than an order of magnitude
better then microseconds.

Replace decicycles with the neutral UNITS. Decicycles is strange but
tenths of a nanosecond and unspecific "deci"-ticks for mach_absolute_time
is just silly.

e3fec3f095 arm: Add EXTERN_ASM to the .func and .type declarations for exported symbols
This makes the generated assembly more internally consistent,
avoiding declaring two labels for the same function (for cases
where EXTERN_ASM is empty) and not declaring a separate unprefixed
label in other cases.

This also makes sure the .func and .type delcarations have the same
prefix. They have previously not been used on the platforms
that have prefixed symbols on arm (iOS), but gas-preprocessor
has recently started using the .func declarations for adding
.thumb_func declarations for such functions.

5dae487235 arm: Allow overriding the alignment set in the function macro
The function macro always sets .align 2 before declaring the
function label (since 5c5e1ea3) and always sets the section to
.text (since 278caa6a).

The .align 5 before certain functions, added in fc252eba, were added
before .text and .align were added to the function macro and thus
became useless/unused when the function macro got them.

This restores the original intention, to align the loop entry
points.

01d245ef43 random_seed: Rewrite the generic clock() based seed code
The new code is faster and reuses the previous state in case of
multiple calls.

The previous code could easily end up in near-infinite loops,
if the difference between two clock() calls never was larger than
1.

This makes fate-parseutils finish in finite time when run in wine,
if CryptGenRandom isn't available (which e.g. isn't available if
targeting Windows RT/metro).

Patch originally by Michael Niedermayer but with some modifications
by Martin Storsjö.

645c94b61b Revert "Merge commit '3bc2e89c76e88ae6f1fd5287e0b11abcfc3c601c'" (Bump libavutil major version to account for the LLS API/ABI changes.)
This reverts commit 792845e436, reversing
changes made to 1d6666a6b8.

Bumping libavutil requires all libraries that use libavutil to have their
major version bumped (yes breakage has been confirmed this is not a hypotheses)

One case of breakage is due to new types being added to AVOptions and
applications that linked to old libavutil and libswresample
then trying to use old libavutil (its soname changed so the old isnt updated)
and new swresample (its soame didnt change so it is updated)
the new swresample contains AVOption types that the old libavutil doesnt
know of thus the application attempting to access these avoptions
fails

AVOptions are used by all libs so the issue can potentially happen with
any other lib, libswresample was just the first that showed the problem
ive not checked if the other libs are affected currently by the same issue
or not

Also in addition to AVOptions, AVFrames are also defined in
libavutil, bumping it without all libs that use AVFrames could lead to
serious inconsistencies when 2 libs/app end up using 2 different libavutils

The alternative of bumping all is still possible after this revert, if it
turns out to be the preferred solution

56572787ae Add Windows resource file support for shared libraries
Originally written by James Almer <jamrial@gmail.com>

With the following contributions by Timothy Gu <timothygu99@gmail.com>

* Use descriptions of libraries from the pkg-config file generation function
* Use "FFmpeg Project" as CompanyName (suggested by Alexander Strasser)
* Use "FFmpeg" for ProductName as MSDN says "name of the product with which the
  file is distributed" [1].
* Use FFmpeg's version (N-xxxxx-gxxxxxxx) for ProductVersion per MSDN [1].
* Only build the .rc files when --enable-small is not enabled.

82b2e9cb1d build: rename version.h to libavutil/ffversion.h
Also the libavutil/ffversion.h will be installed.

Rationale:
* Applications might want to know FFmpeg's version besides the individual
  libraries'.
* Avoids file name clash between FFmpeg's ./version.h and lib*/version.h when
  a library source file includes both and is compiled on an out-of-tree build.

Fixes .

b382d09d29 avutil: reintroduce lls1 as the 52 ABI needs it
lls1 taken from ff130d7

This is incompatible with libavcodec version
55.18.100 to 55.43.100 except 55.39.101
This incompatibility is caused by these libavcodec versions depending on
a libavutil 52 which is ABI incompatible with the previous ABI 52

you can avoid this incompatibility by upgrading your libavcodec so it
does no longer depend on the invalid ABI

19e30a58fc Deprecate obsolete XvMC hardware decoding support
XvMC has long ago been superseded by newer acceleration APIs, such as
VDPAU, and few downstreams still support it. Furthermore XvMC is not
implemented within the hwaccel framework, but requires its own specific
code in the MPEG-1/2 decoder, which is a maintenance burden.

It does not make sense in the vast majority of use cases, no currently

nontrivial, and many of those get it wrong (the "correct" range is
INT_MIN to INT_MAX so that the builtin constant "all" works).

8696e51baf lavu/opt: add AV_OPT_TYPE_CHANNEL_LAYOUT and handler functions
The new type is compatible with AV_OPT_TYPE_INT64, but allows to specify
channel layouts using the format accepted by av_get_channel_layout().

d96e377c39 lavu/channel_layout: change av_get_channel_layout() behavior at the next bump
The new syntax is preferred since it allows backward syntax compatibility
with libswr when switching to the new option handling code with
AV_OPT_TYPE_CHANNEL_LAYOUT.

With the new parser the string:
1234

is interpreted as a channel layout mask, rather than as a number of
channels, and thus it's compatible with the current way to set a channel
layout as an integer (e.g. for the icl and ocl options) making use of
integer option values.

ff_get_channel_layout() with compat=0 will be used in the
AV_OPT_TYPE_CHANNEL handler code.

The user is encouraged to switch to the new forward compatible syntax,
which requires to put a trailing "c" when specifying a layout as a number
of channels.

3e2fa991db x86inc: remove misaligned cpu flag
Prevents a crash if the misaligned exception mask bit is
cleared for some reason.

Misaligned SSE functions are only used on AMD Phenom CPUs
and the benefit is miniscule. They also require modifying
the MXCSR control register and by removing those functions
we can get rid of that complexity altogether.

25cb0c1a1e x86inc: activate REP_RET automatically
Now RET checks whether it immediately follows a branch, so the
programmer dosen't have to keep track of that condition. REP_RET
is still needed manually when it's a branch target, but that's
much rarer.

The implementation involves lots of spurious labels, but that's OK
because we strip them.

d5b58f678d tools: add benchmark for crypto functions.
The benchmark tests the speed of the following algorithms:
MD5, SHA-1, SHA-256, SHA-512, RIPEMD-160, AES-128.

It can optionally be built to perform the same benchmark on
other crypto libraries, for comparison purposes.
The supported libraries are:
- crypto:   OpenSSL's libcrypto;
- gcrypt:   GnuTLS's libgcrypt;
- tomcrypt: LibTomCrypt
To enable them, use this syntax:
make VERSUS=crypto+gcrypt+tomcrypt tools/crypto_bench
They do not need to have been enabled in configure.

e743e7ae6e libavutil: Make avpriv_open a library-internal function on msvcrt
Add one copy of the function into each of the libraries, similarly
to what we do for log2_tab. When using static libs, only one
copy of the file_open.o object file gets included, while when
using shared libraries, each of them get a copy of its own.

This fixes DLL builds with a statically linked C runtime, where
each DLL effectively has got its own instance of the C runtime,
where file descriptors can't be shared across runtimes.

On systems not using msvcrt, the function is not duplicated.

33237123c8 libavutil: Enable the MSVC DLL symbol loading workaround in shared builds as well
This used to only be necessary in static builds (when using the
dynamically linked C runtime), since the _imp prefixed symbols do
exist when linking to the actual DLL. When building testprogs,
however, the current library (e.g. libavutil for some of the testprogs)
is linked statically.

This fixes make fate on DLL builds when using the dynamically
linked C runtime.

dfc6b5c814 file: Move win32 utf8->wchar open wrapper to libavutil
When libavformat was changed to use the new avpriv_open function
in 51eb213d00, this silently bypassed the existing wrapper for
win32. Move the win32 wrapper into libavutil/file.c to make sure
it gets called everywhere (not just in the libavformat case).

This makes sure that non-ascii file names gets opened properly
(where file names internally are stored as utf8, but they get
converted to wchar_t and opened with _wsopen).

c7e921a54f avopt: Check whether the object actually has got an AVClass
AVIOContext has got an av_class member that only gets set if
opening the context using avio_open2, but not if allocating a
custom IO context. A caller that wants to read AVOptions from
an AVIOContext (recursively using AV_OPT_SEARCH_CHILDREN) may
not know if the AVIOContext actually has got a class set or not.

5efbeae38c configure: rename have_incompatible_fork_abi -> have_incompatible_libav_abi
"Fork" is an ambiguous term, since there may be more than one fork, also
"fork" could be confused with the corresponding function. Also it seems
important to point the name of the referenced fork in the symbol.

Note: the old --enable-incompatible-fork-abi command is retained for
compatibility, although it should be considered deprecated.
