Change "file:stream[:syncfile:syncstream]" to
"file.stream[:syncfile.syncstream]", the latter syntax is more
consistent with the stream identifier form printed by
av_dump_format(), and more readable. Both syntaxes are currently
accepted by the opt_map() code.

This leaves fft.h with only the core FFT and MDCT definitions
thus making it more managable.

These windows do not really belong in fft/mdct files and were
easily confused with the similarly named tables used by rdft.

This function is not tightly coupled to mdct, and it's in the way
of making a fixed-point mdct implementation.

This removes the rather pointless wrappers (one not even inline)
for calling the fft_calc and related function pointers.

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.

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.

Fix warning:
ffplay.c: At top level:
ffplay.c:3027: warning: missing braces around initializer
ffplay.c:3027: warning: (near initialization for ‘options[53].u’)

Fix crash if ic->pb is NULL and ic->pb->error is evaluated. This
happens for example with: ffplay photo.jpeg.

This way building ffmpeg on mingw won't require windows specific tools

This avoids the main/SDL_main declaration clash caused by SDL on
Windows and other platforms.

Since initially committed in 2004, this codec has only been touched
for maintenanance.  Functionally, it contains no novel ideas and
its intended audience is better served by existing mature codecs.

This allows the AC-3 decoder to be used directly with RealMedia
decoders that unlike the libavformat one do not byte-swap automatically.
Since the new code is only used in case we would fail directly otherwise
there should be no risk for regressions.
The "buf" pointer needs to be overwritten since otherwise the CRC check fails.

draw_slice() checks that the fade factor is < 65536 and only
calculates the fade if so. But the fade factor is clipped in
end_frame() by av_clip_uint16() to 65535, so the fade is calculated
for every frame.  This patch alters the check so that it compares with
< 65535 (UINT16_MAX).

draw_slice() checks that planes 0 and 1 of AVFilterBufferRef's data
are not NULL before manipulating planes 1 and 2. This patch makes the
check against planes 1 and 2. More senseful and possibly more robust.

This fixes ugliness when configure outputs its (empty) results on HPUX
(maybe some other UNIXes too):

Enabled indevs:

and use in scale_coefficients() for the floating-point AC-3 encoder.

This updates the seek test reference to match de11ee90.  Before this
change, most of the seeks requested positions before the supposed
start of the file (the preroll time), resulting in the first packet
being returned.  With the preroll subtracted, some of these seeks
will land within the file and some beyond the end, thus returning
a different set of packets.
