It was used for an old implementation of the SBR filterbank.
./configure --disable-everything --disable-ffplay --enable-decoder=aac works.
This restores the behaviour of running only the builtin
regression tests when no path to external samples is given.
aa3805a inadvertently broke this by always setting SAMPLES
to something. Using := makes the ifdef test work as expected
when the FATE_SAMPLES environment variable is empty.

Stripping is generally best left to package management tools, and
since unstripped copies are kept in the build tree, any arguments
about saving space (no matter how insignificant) are void.

When -std=c99 is used, GCC defines __STRICT_ANSI__ to hide non-ANSI
interfaces; on MinGW32, when this macro is defined, some functions that are
part of POSIX but not of Windows APIs are disabled, including strcasecmp().

ICC lies about the version of gcc it emulates, which results

Conio.h is a non-standard header and may not have kbhit()
prototyped. This fixes compile on OS/2 where the EMX version (we're
using a fork) of conio.h only has getch() and getche().

Remove usage of tcgetattr and tcsetattr to modify terminal
parameters, and rely on ctrl-c to stop instead of pressing 'q'.
On systems with conio.h, keep the old behavior.
Changing the terminal settings causes problems if multiple instances
are running asynchronously on the same terminal, such as during a
parallel FATE run, or if the process crashes before restoring the
terminal. In both cases, the terminal state is messed up requiring
a manual reset.

This makes existing pkg-config uses as well as the libsdl checks
use the new pkg-config helper functions, which should be more
robust against broken systems.
Signed-off-by: Mans Rullgard <mans@mansr.com>
This adds helper functions for checking packages with pkg-config
and managing the associated flags.
Note that pkg-config use is still discouraged due to widespread
poor practices resulting in broken flags in many situations. A
few badly designed packages require flags only obtainable using
pkg-config, and these functions are intended for those cases.

This makes it possible to pass a space-separated list of functions
to check_func_headers and check_lib2. If any function is missing,
none are enabled as available, so this should only be used for
all-or-nothing sets, i.e. groups in which none will be used if any
one is missing.

It is pretty hopeless that other considerable projects will adopt
libavutil alone in other projects. Projects that need small footprint
are better off with more specialized libraries such as gnulib or rather
just copy the necessary parts that they need. With this in mind, nobody
is helped by having libavutil and libavcore split. In order to ease
maintenance inside and around FFmpeg and to reduce confusion where to
put common code, avcore's functionality is merged (back) to avutil.

Recent gcc versions define __ARM_PCS or __ARM_PCS_VFP to indicate the
VFP ABI in use, and ARM RVCT defines __SOFTFP__ when using this ABI.
If none of these are defined, check $cross_prefix and $cc for the
substring "hardfloat", and finally fall back to a linker test. This
gives the correct result in most configurations.
Some linkers fail if this flag is used when creating an executable file.
Since the flag is meaningful only for shared libraries, dropping it from
the main link flags is correct.
Fixed-point AC-3 encoder renamed to ac3_fixed.
Regression test acodec-ac3 renamed to acodec-ac3_fixed.
Regression test lavf-rm changed to use ac3_fixed encoder.

This macro is disabled if --enable-small or --disable-optimizations are set.
Currently, this leads to warnings about functions being defined but not used,
for functions in header files.
By defining av_always_inline as inline or as av_unused, we avoid these
warnings.
This doesn't make a normal build with --enable-small any larger,
since the compiler probably chooses not to inline these functions even
if they're marked as inline.

The SAP muxer uses network functions directly, uses the rtp protocol and the
udp protocol. The network functions and the udp protocol are both transitively
enabled via the rtp protocol, so that's the only dependency that needs to

On OS X, this struct is only available if _DARWIN_C_SOURCE is defined,
when we have _POSIX_C_SOURCE defined. This allows the struct to be found,
enabling proper IPv6 multicast functionality on OS X.
The define is already set within the file that uses the struct. Setting it
only for this test in configure avoids having to keep it defined for the
whole build.
