This allows installing into e.g. /usr/lib/ffmpeg and binaries linked
against ffmpeg will pick these .so file while binaries linked against
some fork or different version will pick the libraries in /usr/lib.
There will be still some issues for binaries that (indirectly) end up
depending on multiple variants, but for the simpler cases it should allow
different applications to use different (compatible) variants that
are installed at the same time.

configure: Avoid requiring c99wrap for working around msys path issues
Conflicts:
configure
Merged-by: Michael Niedermayer <michaelni@gmx.at>
Msys is unable to convert unix style absolute paths to windows style
paths when combined with certain multichar MSVC options such as
-Fo<file>. We used to work around this issue by passing them as two
separate parameters separated by a space to c99wrap, which then mapped
them back to the actual parameter format that MSVC uses.
The only paths that actually are an issue are absolute unix style
paths, and the only place such absolute paths are used with the output
arguments (-Fo, -Fe, -Fi, -out:) are for the temp files within configure.
By setting TMPDIR to . for msvc/icl builds, we never need to use
absolute unix style paths for the file output, and we can use the
actual proper form of the file output parameters. This avoids requiring
the c99wrap wrapper for remapping the parameters for cases where the
c99 converter isn't invoked at all (MSVC2013 and ICL).

On some platforms (such as msys), symlinks are (poorly) emulated
by simply creating a copy of the file.
This means that when building out of tree, the build tree gets
a copy of the original makefile, which can lead to unintuitive
build errors when the original makefile gets updated later.
Instead simply create a stub makefile which includes the real
one.

MSVC does support enough of C99 to work without the converter since
the 2013 version. Try to detect which version of the compiler in
the path needs to run the C99 converter or not. When the converter
is omitted, compilation time is reduced quite drastically.
Prior to this, users could still use --cc="c99conv -noconv cl"
when running MSVC 2013 to achieve the same.
This checks the version number instead of doing a normal compile
test, since this check needs to be done earlier in configure, before
the normal compile test helpers are usable.

Merged-by: Michael Niedermayer <michaelni@gmx.at>
For some weird reason gcc does not check if the -Wno disabling variants
of warning flags match existing warning flags. Instead it swallows them
silently. That is, unless other warning or error messages are generated,
because then - for some even more bizarre reason - a complaint about the
unknown disable warning flag is issued along with the error or warning
message.
Thus to check for the availability of a warning disabling option, one
needs to check for the enabling variant instead and then add the
disabling variant to CFLAGS.

Replace the inline awk script with a Perl script which tracks the

This allows to correctly track dependencies for files including files
with a second level include (for example: ffmpeg-devices.texi ->

This also adds a dependency on perl for computing the dependencies, which
should not be a problem since perl is already required all the way for

Change the check_exec_crash test to use a function pointer instead of
simply calling the function. The EBP availability test will crash when
compiled with ICL likely due to compiler optimization shenanigans.
Originally the check_exec_crash code was moved out of main to fix a
problem with gcc's treatment of non-leaf main on x86_32. Libav already
moved the code out of main but the addition of the function pointer will
prevent any inlining which fixes the remaining problem.
A function pointer is used since it is compiler agnostic (as opposed to
say __attribute__ ((noinline)) which would only work with gcc compatible
compilers).

If building libav with -MD in the cflags (for making the MSVC compiler
generate code for using a dynamically linked libc), the system headers
that declare strtod, snprintf and vsnprintf declare the functions as
imported from a DLL. To hook up wrappers of our own for these functions,
the function names are defined to avpriv_*, so that the calling code
within libav calls the wrappers instead. Since these functions
are declared to be imported from DLLs, the calling code expects to
load them from DLL import function pointers (creating references to
_imp__avpriv_strtod instead of directly to avpriv_strtod). If the
libav libraries are not built as DLLs, no such function pointers (as
the calling code expects) are created.
The linker can fix this up automatically in some cases (producing
warnings LNK4217 and LNK4049), if the object files are already
included. By telling the linker to try to include those symbols
(without the _imp prefix as the calling code ends up using),
we get the object files included, so that the linker can do the
automatic fixup. This is done via config.h, so that all (or at least
most) of the object files in our libraries force including the compat
files, to make sure they are included regardless of what files from our
static libraries actually are included.

The next commit will introduce a proper decimation filter to be used
along with the field matching filter. To avoid confusion with this
filter which has currently a very limited usage (and will not work
properly with the fieldmatching filter), the new decimation filter will
take the decimate name, and this filter is renamed to mpdecimate.

The gcov/lcov are a common toolchain for visualizing code coverage with
the GNU/Toolchain. The documentation and implementation of this
integration was heavily inspired from the blog entry by Mike Melanson:

configure: Check for the atomic.h functions used in the suncc atomics header
Conflicts:
configure
Merged-by: Michael Niedermayer <michaelni@gmx.at>
The "suncc" atomics implementation uses a suncc specific memory
barrier, but also relies on a few atomic functions from atomic.h,
that are not suncc specific but specific to solaris. This made
the current implementation fail on suncc on linux.

configure: fix dependencies of XvMC and old vdpau mpeg2 decoders
Merged-by: Michael Niedermayer <michaelni@gmx.at>
This makes standalone compilation of the eatqi decoder
succeed. The dependency comes from the shared mpeg12dec.o file.

h264: Make it possible to compile without error_resilience
Conflicts:
configure
libavcodec/h264.c
Merged-by: Michael Niedermayer <michaelni@gmx.at>
Error resilience is enabled by the h264 decoder, unless explicitly
disabled. --disable-everything --enable-decoder=h264 will produce
a h264 decoder with error resilience enabled, while
--disable-everything --enable-decoder=h264 --disable-error-resilience
will produce a h264 decoder with error resilience disabled.

This allows dropping the mpegvideo dependency from a number of
components.
This also fixes standalone building of the h264 parser, which
was broken in 64e438697.

Dynamically loads the library itself, rather than through VfW.
Supports AvxSynth on Linux and OS X.
Supports the new colorspaces added in AviSynth 2.6 when used
with AviSynth 2.6.
Only compile if CONFIG_ENCODERS is enabled, i.e. if at least one
encoder is to be compiled. This prevents it from being includes in
a decoder-only build.
