These functions are using the POSIX clock_gettime() function with the
CLOCK_MONOTONIC clock id. If these are not present on the targeted
platform, the new functions will fallback on using the original realtime functions
av_gettime() and av_usleep().
Monotonic support can be added on other platforms with their
equivalent native system API eventually if possible.
Whenever time is requested to measure relative time, the monotonic clock,
when available, is superior to the system realtime clock because it is
not affected by discontinuous jumps in the system time
In a future step, offering the flexibility to let the user choose between
rt and monotonic clock for avdevices packets will be investigated.
It is very easy to experience the issues that this patch attempt to address
by rewinding back in the past the system time while ffmpeg is running.

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.

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

Conflicts:
libavutil/version.h
Bump done to stay compatible with libav, its not neccessary otherwise for ffmpeg
as we have the new ABI/API under LLS2 and the old (unused) under LLS
Merged-by: Michael Niedermayer <michaelni@gmx.at>
Commit 41578f70cf changed the LLS API, which was
called from libavcodec. Thus using an old libavcodec with a new libavutil will
break.
All scheduled API changes are deferred to the next bump.
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#1769.

This incompatibility is caused by these libavcodec versions depending on

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

VDPAU, and few downstreams still support it. Furthermore XvMC is not
implemented within the hwaccel framework, but requires its own specific

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.
