This reorders the lfe_fir tables, and drops the mirrored half,
such that the loops in lfe_interpolation_fir() can be simplified.
The new loop structure should be easier to implement with SIMD.
Static data size is reduced by 2kB.
3% faster on Cortex-A8.

This prevents gcc reloading the value from memory on each iteration
of the loop.

Optimised implementations of the synth filter will require these
arrays 16-byte aligned.

Call the RDFT by a function pointer like other FFT related transforms.
This makes instruction set optimized versions possible.

If the format probe hits end of file, do not add the error code
to the buffer position. This is obviously wrong, and with a
small input file would cause a negative buffer overflow.
Fixes issue 1818.

Both bash and ksh abuse this variable even in POSIX mode, leading
to unpleasant surprises.

This moves the H264-specific functions from DSPContext to the new
H264DSPContext. The code is made conditional on CONFIG_H264DSP
which is set by the codecs requiring it.
The qpel and chroma MC functions are not moved as these are used by
non-h264 code.

This adds a "fate" make target which runs the full FATE test suite.
Individual tests can be run with "make fate-$testname".
The location of the FATE test samples must be specified with the
--samples=PATH option to configure.
The tests/fate-update.sh script regenerates the references files and
test list from the online FATE database. These are checked in since
generating them requires non-standard tools.

The init function is only compiled if MMX is enabled, the call

This moves the DWT functions from snow.c and dsputil.c to a file of
their own. A new struct, DWTContext, holds the function pointers
previously part of DSPContext.

w53_32_c() and w97_32_c() are defined as stubs when snow encoder is
disabled. In this case, those functions are not referenced at all
and do thus not need to be defined.

These casts are correct and safe. The pointers are guaranteed to
have proper alignment, and aliasing is not a problem with character
types.

This disables all codecs, formats, etc. It saves some typing when
only a few components are desired.

The presence of the .SECONDARY directive caused thing to not always
be correctly rebuilt. Mentioning the object files explicitly as
targets gives the desired result of make not deleting them without
unpleasant side-effects.

Force version.sh to run whenever the version might have changed,
regardless of what is being built. This is done by attaching the
dependencies to a dummy file (.version) which is included from the
makefile. As make will always attempt to rebuild any included files
before considering other rules, this ensures that the real version.h
is (re-)created before it is required by any source file.

This silly program always writes its output to the current directory.
Changing directory is better than moving the file afterwards.

This reduces the number of false dependencies on header files and
speeds up compilation.

ffmpeg.c uses lrintf(), which is missing on some systems. Previously
it picked up the replacement via libavutil/internal.h due to
HAVE_AV_CONFIG_H being erroneously defined.
Moving these replacements to a separate header enables ffmpeg.c to
use them without being exposed to internal interfaces.
This use of a non-public header is justified by the header in question
not being part of the internal interface either. It should rather be
considered as part of the build system, which is shared between the
libraries and the applications.
This header cannot be installed since the tested conditions depend on
the compiler.

This is a bit hackish. I will try to think of something nicer, but
this will do for now.

Some of the per-arch headers are only meant to be used through
the parent header of the same name. Testing these standalone
does not make sense.

This unused header is a placeholder for work in progress(?).

This deprecated function is only used by ffserver, yet does not have
a prototype visible there.
In the long term, ffserver should be made IPv6-aware. In the meantime,
this change removes cruft from lavf and fixes some warnings in ffserver.

This function is not referenced outside this file and has no
prototype. Feel free to flame if this is wrong.
Originally committed as revision 22314 to svn://svn.ffmpeg.org/ffmpeg/trunk
This makes it an error to not have a prototype in scope for
a function with external linkage. The flag is only enabled
for gcc due to -Werror=type not working with all compilers.

ffserver-regression.sh doesn't need anything else from

intreadwrite.h is not part of the public API and should thus
