WebPAnimEncoder API is a combination of encoder (WebPEncoder) and muxer
(WebPMux). It performs several optimizations to make it more efficient
than the combination of WebPEncode() and native ffmpeg muxer.
When WebPAnimEncoder API is used:
- In the encoder layer: we use WebPAnimEncoderAdd() instead of
WebPEncode().
- The muxer layer: works like a raw muxer.
On the other hand, when WebPAnimEncoder API isn't available, the old code is
used as it is:
- In the codec layer: WebPEncode is used to encode each frame
- In the muxer layer: ffmpeg muxer is used

Use the Multi-library interface to load at runtime x265 libraries
supporting alternative bit depths (e.g. 8bit and 16bit).
The linked library will try to load the library supporting the
pixel format if it is not supported by itself.
Fallback requesting the native library (passing 0 to x265_api_get) if
a library supporting the requested bit depth is not available.

ffmpeg can now use the x265 multi-library interface to make a runtime
selection between a number of libx265 libraries (perhaps 8bpp and 16bpp).
ffmpeg will link to one build of libx265 (statically or
dynamically) and this linked version of libx265 will support one
bit-depth (8 or 10 bits). At runtime, ffmpeg now has the option to request the
encoder to use a different bit depth(8 or 10). If the requested bitdepth
is zero, or if it matches the bitdepth of the system default libx265 (the
currently linked library), then this library will be used for encode.
If ffmpeg requests a different bit-depth, the linked libx265 will attempt
to dynamically bind a shared library with the requested bit-depth from the install
location (default or user-specified).
new x265 API:
const x265_api* api = x265_api_get(int bitDepth);
x265_api - holds the libx265 public API functions
bitDepth - requested API for 8bpp or 16bpp
note: Use 0 to indicate native bit depth of the linked libx265 and
x265_api_get(0) is guaranteed to return a non-null pointer

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.
