Merged-by: Michael Niedermayer <michaelni@gmx.at>
Move the GNU as check before the arch specific asm checks since the .dn
check requires gas compatible assembler.
Disable the VC-1 motion compensation NEON asm which is the only part
using that directive. The integrated assembler in the upcoming clang 3.5
does not support .dn/.qn without plans to change that. Too much effort
to implement it while it is rarely used.

Clang Undefined Behaviour Sanitizer seems to make non-constant constant

inline assembly if no optimization is requested.
Add -O1 to the cflags to hide the misbehaviour.

Fate tests pass with both avresample as well as swresample based opus decoder, but

if theres an alternative or if they could be avoided, they also dont match the

Allow the configure tool to call the gas-preprocessor with an absolute
path when included with either the "--as" or with a separate "--gas"
option. The patch is backward compatible and will not break any current
configuration setups.
The new behavior that comes with this option can be utilized in the
following ways:
Examples:
- Just as single option that includes both the gas-preprocessor.pl and
cc/as at the same time:
$ configure --as="/opt/app/build-tools/gas-preprocessor.pl \
/Applications/Xcode.app/.../Developer/usr/bin/gcc"
- Call gas-preprocessor with a separate option in conjunction with --as:
$ configure --gas="/opt/app/build-tools/gas-preprocessor.pl" \
--as="/Applications/Xcode.app/.../Developer/usr/bin/gcc"
- Address only the the gas-preprocessor and it will automatically fall
back to as or cc whichever that's defined:
$ configure --gas="/opt/app/build-tools/gas-preprocessor.pl"
- Or if no gas-preprocessor.pl is explicitly defined, it falls back to
the old behaivor.
Some compilers when given -x objective-c will tell that they dont support
that but return success. Using a .m file instead returns proper failure in
that case
This should fix a build failure on freebsd

Based on original code by Christophe Gisquet in 2010, updated to work
with current ffmpeg APIs.
Supports grabbing a single window or an area of the screen, including
support for multiple monitors (Windows does funky stuff with negative
coordinates here).
I've moved most of the configuration to AVOptions; the input file name
is now only the string "desktop", or "title=<windowname>" to select a
single window. The AVOptions are the same as x11grab where possible.
Code has been added to support a "show_region" mode, like x11grab, which
will draw a rectangle on the screen around the area being captured.
Instead of duplicating code for paletted image handling, I make use of
the GDI API's ability to output DIB (BMP) images, which can be run
through ffmpeg's existing BMP decoder.
