-   topic, feel free to join us on the #ffmpeg IRC channel (on
-   irc.freenode.net).
+   The FFmpeg Project proudly presents FFmpeg 2.6 "Grothendieck", about 3
+   months after the release of FFmpeg 2.5.
 
-   ┌────────────────────────────┐
-   │ 🔨  API Information         │
-   └────────────────────────────┘
+   A lot of important work got in this time, so let's start talking about what
+   we like to brag the most about: features.
 
-     FFmpeg 2.5 includes the following library versions:
+   A lot of people will probably be happy to hear that we now have support for
+   NVENC — the Nvidia Video Encoder interface for H.264 encoding — thanks to
+   Timo Rothenpieler, with some little help from NVIDIA and Philip Langdale.
 
-       • libavutil      54.15.100
-       • libavcodec     56.13.100
-       • libavformat    56.15.102
-       • libavdevice    56. 3.100
-       • libavfilter     5. 2.103
-       • libswscale      3. 1.101
-       • libswresample   1. 1.100
-       • libpostproc    53. 3.100
+   People in the broadcasting industry might also be interested in the first
+   steps of closed captions support with the introduction of a decoder by
+   Anshul Maheswhwari.
 
-     Important API changes since 2.4:
+   Regarding filters love, we improved and added many. We could talk about the
+   10-bit support in spp, but maybe it's more important to mention the addition
+   of colorlevels (yet another color handling filter), tblend (allowing you
+   to for example run a diff between successive frames of a video stream), or
+   eventually the dcshift audio filter.
 
-       • avpriv_dv_frame_profile2() has been deprecated
+   There is also two other important filters landing in libavfilter: palettegen
+   and paletteuse, submitted by the Stupeflix company. These filters will be
+   very useful in case you are looking for creating high quality GIF, a format
+   that still bravely fights annihilation in 2015.
 
+   There are many other features, but let's follow-up on one big cleanup
+   achievement: the libmpcodecs (MPlayer filters) wrapper is finally dead. The
+   last remaining filters (softpulldown/repeatfields, eq*, and various
+   postprocessing filters) were ported by Arwa Arif (OPW student) and Paul B
+   Mahol.
 
-     Please refer to the doc/APIchanges file for more information.
+   Concerning API changes, not much things to mention. Though, the introduction
+   of devices inputs and outputs listing by Lukasz Marek is a notable addition
+   (try ffmpeg -sources or ffmpeg -sinks for an example of the usage). As
+   usual, see doc/APIchanges for more information.
 
- ┌────────────────────────────┐
- │ ★  List of New Features    │
- └────────────────────────────┘
+   Now let's talk about optimizations. Ronald S. Bultje made the VP9 decoder
+   usable on x86 32-bit systems and pre-ssse3 CPUs like Phenom (even dual core
+   Athlons can play 1080p 30fps VP9 content now), so we now secretly hope for
+   Google and Mozilla to use ffvp9 instead of libvpx.
 
-   ┌────────────────────────────┐
-   │ ffprobe                    │
-   └────────────────────────────┘
+   But VP9 is not the center of attention anymore, and HEVC/H.265 is also
+   getting many improvements, which includes optimizations, both in C and x86
+   ASM, mainly from James Almer, Christophe Gisquet and Pierre-Edouard Lepere.
 
-    • -show_pixel_formats option
+   Even though we had many x86 contributions, it is not the only architecture
+   getting some love, with Seppo Tomperi adding ARM NEON optimizations to the
+   HEVC stack, and James Cowgill adding MIPS64 assembly for all kind of audio
+   processing code in libavcodec.
 
-   ┌────────────────────────────┐
-   │ ffserver                   │
-   └────────────────────────────┘
+   And finally, Michael Niedermayer is still fixing many bugs, dealing with
+   most of the boring work such as making releases, applying tons of
+   contributors patches, and daily merging the changes from the Libav project.

 In the default mode of operation the encoder has to honor frame constraints

 A frame containing a lot of small details is harder to compress and the encoder

@@ -90,6 +91,56 @@ To build FFmpeg, you need to install the development package. It is usually
 called @file{libfoo-dev} or @file{libfoo-devel}. You can remove it after the
 build is finished, but be sure to keep the main package.
 
+@section How do I make @command{pkg-config} find my libraries?
+
+Somewhere along with your libraries, there is a @file{.pc} file (or several)
+in a @file{pkgconfig} directory. You need to set environment variables to
+point @command{pkg-config} to these files.
+
+If you need to @emph{add} directories to @command{pkg-config}'s search list
+(typical use case: library installed separately), add it to
+@code{$PKG_CONFIG_PATH}:
+
+@example
+export PKG_CONFIG_PATH=/opt/x264/lib/pkgconfig:/opt/opus/lib/pkgconfig
+@end example
+
+If you need to @emph{replace} @command{pkg-config}'s search list
+(typical use case: cross-compiling), set it in
+@code{$PKG_CONFIG_LIBDIR}:
+
+@example
+export PKG_CONFIG_LIBDIR=/home/me/cross/usr/lib/pkgconfig:/home/me/cross/usr/local/lib/pkgconfig
+@end example
+
+If you need to know the library's internal dependencies (typical use: static
+linking), add the @code{--static} option to @command{pkg-config}:
+
+@example
+./configure --pkg-config-flags=--static
+@end example
+
+@section How do I use @command{pkg-config} when cross-compiling?
+
+The best way is to install @command{pkg-config} in your cross-compilation
+environment. It will automatically use the cross-compilation libraries.
+
+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
+using the @code{PKG_CONFIG_LIBDIR}, as explained in the previous entry.
+
+As an intermediate solution, you can place in your cross-compilation
+environment a script that calls the host @command{pkg-config} with
+@code{PKG_CONFIG_LIBDIR} set. That script can look like that:
+
+@example
+#!/bin/sh
+PKG_CONFIG_LIBDIR=/path/to/cross/lib/pkgconfig
+export PKG_CONFIG_LIBDIR

 @section ffmpeg does not work; what is wrong?
@@ -416,6 +467,40 @@ point acceptable for your tastes. The most common options to do that are
 @option{-qscale} and @option{-qmax}, but you should peruse the documentation
 of the encoder you chose.
 
+@section I have a stretched video, why does scaling does not fix it?
+
+A lot of video codecs and formats can store the @emph{aspect ratio} of the
+video: this is the ratio between the width and the height of either the full
+image (DAR, display aspect ratio) or individual pixels (SAR, sample aspect
+ratio). For example, EGA screens at resolution 640×350 had 4:3 DAR and 35:48
+SAR.
+
+Most still image processing work with square pixels, i.e. 1:1 SAR, but a lot
+of video standards, especially from the analogic-numeric transition era, use
+non-square pixels.
+
+Most processing filters in FFmpeg handle the aspect ratio to avoid
+stretching the image: cropping adjusts the DAR to keep the SAR constant,
+scaling adjusts the SAR to keep the DAR constant.
+
+If you want to stretch, or “unstretch”, the image, you need to override the
+information with the
+@url{http://ffmpeg.org/ffmpeg-filters.html#setdar_002c-setsar, @code{setdar or setsar filters}}.
+
+Do not forget to examine carefully the original video to check whether the
+stretching comes from the image or from the aspect ratio information.
+
+For example, to fix a badly encoded EGA capture, use the following commands,
+either the first one to upscale to square pixels or the second one to set
+the correct aspect ratio or the third one to avoid transcoding (may not work
+depending on the format / codec / player / phase of the moon):
+
+@example
+ffmpeg -i ega_screen.nut -vf scale=640:480,setsar=1 ega_screen_scaled.nut
+ffmpeg -i ega_screen.nut -vf setdar=4/3 ega_screen_anamorphic.nut
+ffmpeg -i ega_screen.nut -aspect 4/3 -c copy ega_screen_overridden.nut
