The reasoning behind this addition is that various third party
applications are interested in getting some motion information out of a
video "for free" when it is available.
It was considered to export other information as well (such as the intra
information about the block, or the quantization) but the structure
might have ended up into a half full-generic, half full of codec
specific cruft. If more information is necessary, it should either be
added in the "flags" field of the AVMotionVector structure, or in
another side-data.
This commit also includes an example exporting them in a CSV stream.
this allows disabling and enabling it
it also prevents crashes if vfpv3 and neon are disabled which previously
would have enabled the flag
And last but not least one can enable setend on cpus like cortex-a8 where
its fast but disabled by default

On mingw64 with c++11 support, the link libraries do contain a
nanosleep function, while it isn't exposed via the headers. Using
check_func_headers instead of a plain check_func fixes this
misdetection.

configure: Suggest upgrading gas-preprocessor instead of just installing
Merged-by: Michael Niedermayer <michaelni@gmx.at>
The -MD option (for enabling a dynamically linked crt) gets interpreted
as a cpp option for generating dependency information (into a file named
'-.d', when preprocessing to a pipe). We shouldn't be passing
any and all C compiler flags to armasm (which is a plain assembler,
only with cpp bolted on via gas-preprocessor), but these are the
main conflicting ones.

This removes the avcodec dependency and make the code almost twice as
fast. More to come.
The DCT factorization is based on "Fast and numerically stable
algorithms for discrete cosine transforms" from Gerlind Plonkaa &

configure: Include the armcc build number in the compiler identification
Merged-by: Michael Niedermayer <michaelni@gmx.at>
This tries to find the most expressive part of the output of
armcc --vsn to include, giving a compiler identification of
"ARM Compiler 5.04 update 2 (build 82)" instead of just
"ARM Compiler 5.04" for armcc 5.0.
4.x versions of armcc output the following, for "armcc --vsn":
ARM C/C++ Compiler, RVCT4.0 [Build 925]
For evaluation purposes only
Software supplied by: ARM Limited
ARM C/C++ Compiler, 4.1 [Build 894]
For evaluation purposes only
Software supplied by: ARM Limited
5.0 versions output this:
Product: ARM Compiler 5.04
Component: ARM Compiler 5.04 update 2 (build 82)
Tool: armcc [5040081]

llvm's integrated assembler supports the AArch64 asm on darwin since
August 2014. So check $as first before using gas-preprocessor.pl via
$gas. Makes the checks specific for that the architecture specific asm
needs. PPC Altivec and AArch64 needs on ':vararg' for macro arguments.
Arm needs in addition the '.altmacro' directive.
Initialise VC1DSPContext for parser as well as for decoder.
Note, the VC-1 code doesn't actually use the function pointer yet.

pulse-simple is additional library built on top of PulseAudio.
It causes ffmpeg to link to library which is not needed anymore.
This commit removes that redundant dependency.
