+   ┌────────────────────────────┐
+   │ *  API Information         │
+   └────────────────────────────┘
+
+     FFmpeg 2.3 is completely source-compatible to the FFmpeg 2.2 series. There
+     are however some API deprecations that you need to take care of. Use `git
+     diff n2.2 n2.3 doc/APIchanges` to show the list of added and deprecated
+     APIs. FFmpeg 2.3 includes the following library versions:
+
+       • libavutil      52.92.100
+       • libavcodec     55.69.100
+       • libavformat    55.48.100
+       • libavdevice    55.13.102
+       • libavfilter     4.11.100
+       • libswscale      2. 6.100
+       • libswresample   0.19.100
+       • libpostproc    52. 3.100
+
+     Please refer to the doc/APIChanges file for more information.
+
+   ┌────────────────────────────┐
+   │ New Optimization           │
+   └────────────────────────────┘
+
+     We are excited to announce that we have committed new x86 assembly
+     optimization for HEVC, and FFmpeg's audio resampler libswresample. ARM
+     users will get a boost in MLP/TrueHD decoding thanks to new optimization.
+     Decoding Huffyuv also got a major boost from optimization on the C code.
+
+     Of special interest for Microsoft Visual Studio users, we have also
+     converted some preexisting x86 assembly to NASM/Yasm format compatible
+     with MSVC setup, especially in the area of audio resampling.
+
+     Another major feature in this release is the introduction of AArch64
+     (ARMv8) assembly optimization. AArch64 is another name for the first
+     64-bit ARM architecture, used by Apple A7 SoC inside iPhone 5S. Some
+     32-bit ARM assembly has already been ported to AArch64, but more work is
+     underway.
+
+   ┌────────────────────────────┐
+   │ Native Opus decoder        │
+   └────────────────────────────┘
+
+     Opus is an open audio format jointly developed by Xiph.Org, Mozilla,
+     Skype/Microsoft, and Broadcom. It combines the features of the Skype Cilk
+     speech codec and the Xiph.Org CELT music codec into one low-latency
+     codec. Decoding Opus is already possible since FFmpeg 1.0 using the
+     libopus library, but the new Opus native decoder brings a higher level of
+     stability and speed.
+
+   ┌────────────────────────────┐
+   │ QTKit and AVFoundation     │
+   └────────────────────────────┘
+
+     For OS X users, the new QTKit and AVFoundation devices allow you to use
+     the integrated camera on Macs. AVFoundation is a newer API only available
+     on OS X 10.7 "Lion" or newer. For users with older OS X systems, the
+     QTKit device using the older OS X API is for you.
+
+   ┌────────────────────────────┐
+   │ API Additions              │
+   └────────────────────────────┘
+
+     In this release, stream side data are introduced as AVStream.side_data as
+     a way to store miscellaneous stream-wide information. The format is
+     similar to the previously anonymous structure AVPacket.side_data (now
+     named as AVPacketSideData). With this change, audio ReplayGain
+     information and video rotation matrix are now exported through this API,
+     if available in the demuxer.
+
+     We also have improved libswresample's Doxygen API documentation, so new
+     developers wishing to use FFmpeg's excellent libraries can get started
+     more easily and faster.
+
+   ┌────────────────────────────┐
+   │ Last But Not Least         │
+   └────────────────────────────┘
+
+     Other interesting new features including hqx video filter, a pixel art
+     scaling filter; a fixed-point AC-3 decoder contributed by Imagination
+     Technologies; an On2 TrueMotion VP7 video decoder; an HTML5 WebVTT
+     subtitle decoder that allows creation of WebVTT from any text-based
+     subtitles; and an 1-bit Direct Stream Digital audio decoder.

-the lower the more frequent bytes will be modified, with 1 meaning
-every byte is modified.

-@section How do I use @command{pkg-config} when cross-compiling?
-
-The best way is to install @command{pkg-config} in your cross-compilation

-
-You can also use @command{pkg-config} from the host environment by
-specifying explicitly @code{--pkg-config=pkg-config} to @command{configure}.
-In that case, you must point @command{pkg-config} to the correct directories

-
-As an intermediate solution, you can place in your cross-compilation
-environment a script that calls the host @command{pkg-config} with
