3edeb7749e configure: Allow log2 with MSVC 2013 onwards.
Only MSVC 2010 in x64 mode, in the static msvcrt, had a
stray log2 function (which wasn't available in the headers).

MSVC 2013 has got a proper log2 function though.

8a3d9ca603 libavcodec: Add an OpenH264 encoder wrapper
Compared to existing, common opensource H264 encoders, this can be
useful since it has got a different license (BSD instead of GPL).

Performance- and qualitywise it is comparable to x264 in ultrafast
mode.

Hooking it up as an encoder in libavcodec also simplifies comparing
it against other common encoders.

This requires OpenH264 1.3 or newer. Since the OpenH264 API and ABI
changes frequently, only releases are supported.

To take advantage of the OpenH264 patent offer, the OpenH264 library
must not be redistributed, but downloaded at runtime at the end-user's
system.

8ebf02f8f5 libavformat: Only use MoveFileExA when targeting the desktop API subset
The MoveFileExA is available in the headers regardless which API
subset is targeted, but it is missing in the Windows Phone link
libraries. When targeting Windows Store apps, the function is
available both in the headers and in the link libraries, and thus
there is no indication for the build system that this function
should be avoided - such an indication is only given by the
Windows App Certification Kit, which forbids using the MoveFileExA
function.

Therefore check the WINAPI_FAMILY defines instead, to figure out
which API subset is targeted.

fe5e6e34c0 lavf: Add an MPEG-DASH ISOFF segmenting muxer
This is mostly to serve as a reference example on how to segment
the output from the mp4 muxer, capable of writing the segment
list in four different ways:
- SegmentTemplate with SegmentTimeline
- SegmentTemplate with implicit segments
- SegmentList with individual files
- SegmentList with one single file per track, and byte ranges

The muxer is able to serve live content (with optional windowing)
or create a static segmented MPD.

In advanced cases, users will probably want to do the segmenting
in their own application code.

These are ok to use from other libraries even though it's not a

considered more a build system compatibility fallback than a
libavutil feature.)

896a5bff64 arm: check if AS supports .dn
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.

The values of {FLT,DBL}_{MAX,MIN} macros on some systems (older musl
libc, some BSD flavours) are not exactly representable, i.e.
(double)DBL_MAX == DBL_MAX is false
This violates (at least some interpretations of) the C99 standard and
breaks code (e.g. in vf_fps) like
double f = DBL_MAX;
[...]
if (f == DBL_MAX) { // f has not been changed yet

Not guaranteed to be in nanosecond resolution. On iOS 7 the duration
of one tick is 125/3 ns which is still more than an order of magnitude
better then microseconds.

Replace decicycles with the neutral UNITS. Decicycles is strange but
tenths of a nanosecond and unspecific "deci"-ticks for mach_absolute_time
is just silly.
