MSVC 2013 has got a proper log2 function though.

Imagination Technologies has come up with MIPS Warrior Processor Cores.
More details can be found at-
http://www.imgtec.com/mips/warrior/pclass.asphttp://www.imgtec.com/mips/warrior/iclass.asp
This is a preparation patch to submit optimized code for MSA (MIPS-SIMD-Architecture)
This patch set is adding support for P5600 and I6400 CPUs.
MIPS 'generic' case is added, with mips32r2 arch as default (fpu and dsp opt enabled).
Sample configurations for new MSA architectures-
$ ./configure --enable-cross-compile --cross-prefix=<PATH> --arch=mips --target-os=linux --cpu=p5600
$ ./configure --enable-cross-compile --cross-prefix=<PATH> --arch=mips --target-os=linux --cpu=i6400

There are no independant uses of mips32r2 instructions except for the
FPU parts. Due to the heavy use of mips32r2 specifc fpu extensions, I
am guessing the original author intended MIPSFPU to imply MIPS32R2 anyway.
Since these fpu instructions are available on mips64 (non-r2), enable them
there as well.
Also remove the last occurence of HAVE_MIPS32R2 (which is coupled to
HAVE_MIPSFPU anyway).
mips32r2 is left in the list of options form compatability so that using
--disable-mips32r2 doesn't break anything.

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.

libavformat: Only use MoveFileExA when targeting the desktop API subset
Conflicts:
configure
Merged-by: Michael Niedermayer <michaelni@gmx.at>
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.

Try to detect "$cc -static" without "pkg-config --static".
Also, when a library detection using pkg-config fails,
make it explicit this was pkg-config.
The require variant dies if the package is not present.
The check variant does not import the flags to the used list.
The new variant imports the flags if the package is present
but does not die if it is not.
The new call graph is: require -> use -> check.
Use use_pkg_config for libx264 and libsmbclient: more readable
and three external call less per library.

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.
