- │ RELEASE NOTES for FFmpeg 2.4 "Fresnel" │
- └────────────────────────────────────────┘

-   The FFmpeg Project proudly presents FFmpeg 2.4 "Fresnel", just 2 months
-   after the release of 2.3. Since this wasn't a long time ago, the Changelog
-   is a bit short this time.
+              ┌─────────────────────────────────────────────┐
+              │ RELEASE NOTES for FFmpeg 2.6 "Grothendieck" │
+              └─────────────────────────────────────────────┘

-   The most important thing in this release is the major version bump of the
-   libraries.  This means that this release is neither ABI-compatible nor
-   fully API-compatible. But on the other hand it is aligned with the Libav
-   11 release series, and will as a result probably end up being maintained for
-   a long time.
+   The FFmpeg Project proudly presents FFmpeg 2.6 "Grothendieck", about 3
+   months after the release of FFmpeg 2.5.

-   As usual, if you have any question on this release or any FFmpeg related
-   topic, feel free to join us on the #ffmpeg IRC channel (on
-   irc.freenode.net).
+   A lot of important work got in this time, so let's start talking about what
+   we like to brag the most about: features.

-   ┌────────────────────────────┐
-   │ 🔨  API Information         │
-   └────────────────────────────┘
+   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.

-     FFmpeg 2.4 includes the following library versions:
+   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.

-       • libavutil      54.7.100
-       • libavcodec     56.1.100
-       • libavformat    56.4.101
-       • libavdevice    56.0.100
-       • libavfilter     5.1.100
-       • libswscale      3.0.100
-       • libswresample   1.1.100
-       • libpostproc    53.0.100
+   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
+   the dcshift audio filter.

-     Important API changes since 2.3:
+   There are also two other important filters landing in libavfilter: palettegen
+   and paletteuse. Both submitted by the Stupeflix company. These filters will
+   be very useful in case you are looking for creating high quality GIFs, a
+   format that still bravely fights annihilation in 2015.

-       • The new field mime_type was added to AVProbeData, which can
-         cause crashes, if it is not initialized.
-       • Some deprecated functions were removed.
-       • The avfilter_graph_parse function was made compatible with Libav.
-       • The Matroska demuxer now outputs verbatim ASS packets.
+   There are many other new 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, there are not many things to mention. Though, the
+   introduction of device 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. But VP9 is not the
+   center of attention anymore, and HEVC/H.265 is also getting many
+   improvements, which include C and x86 ASM optimizations, mainly from James
+   Almer, Christophe Gisquet and Pierre-Edouard Lepere.

-   ┌────────────────────────────┐
-   │ libavformat                │
-   └────────────────────────────┘
+   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.

-    • Icecast protocol.
-    • API for live metadata updates through event flags.
-    • UTF-16 support in text subtitles formats.
-    • The ASS muxer now reorders the Dialogue events properly.
+   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.

-   ┌────────────────────────────┐
-   │ libavfilter                │
-   └────────────────────────────┘
+   A more complete Changelog is available at the root of the project, and the
+   complete Git history on http://source.ffmpeg.org.

-    • Ported lenscorrection filter from frei0r filter.
-    • Large optimizations in dctdnoiz to make it usable.
-    • Added codecview filter to visualize information exported by some codecs.
-    • Added silenceremove filter.
-
-   ┌────────────────────────────┐
-   │ libavutil                  │
-   └────────────────────────────┘
-
-    • Added clip() function in eval.
-
- ┌────────────────────────────┐
- │ ⚠  Behaviour changes       │
- └────────────────────────────┘
-
-  • dctdnoiz filter now uses a block size of 8x8 instead of 16x16 by default
-  • -vismv option is deprecated in favor of the codecview filter
-  • libmodplug is now detected through pkg-config
-  • HTML documentation generation through texi2html is deprecated in
-    favor of makeinfo/texi2any
-  • ICY metadata are now requested by default with the HTTP protocol
+   We hope you will like this release as much as we enjoyed working on it, and
+   as usual, if you have any questions about it, or any FFmpeg related topic,
+   feel free to join us on the #ffmpeg IRC channel (on irc.freenode.net) or ask
+   on the mailing-lists.

@@ -90,6 +91,56 @@ To build FFmpeg, you need to install the development package. It is usually

+@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}:

+
+If you need to @emph{replace} @command{pkg-config}'s search list

+@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

@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

+This option is used to benchmark all available OpenCL devices and print the
+results. This option is only available when FFmpeg has been compiled with
+@code{--enable-opencl}.
+
+When FFmpeg is configured with @code{--enable-opencl}, the options for the
+global OpenCL context are set via @option{-opencl_options}. See the
+"OpenCL Options" section in the ffmpeg-utils manual for the complete list of
+supported options. Amongst others, these options include the ability to select
+a specific platform and device to run the OpenCL code on. By default, FFmpeg
+will run on the first device of the first platform. While the options for the
+global OpenCL context provide flexibility to the user in selecting the OpenCL
+device of their choice, most users would probably want to select the fastest
+OpenCL device for their system.
+
+This option assists the selection of the most efficient configuration by
+identifying the appropriate device for the user's system. The built-in
+benchmark is run on all the OpenCL devices and the performance is measured for
+each device. The devices in the results list are sorted based on their
+performance with the fastest device listed first. The user can subsequently
+invoke @command{ffmpeg} using the device deemed most appropriate via
+@option{-opencl_options} to obtain the best performance for the OpenCL
+accelerated code.
+
+Typical usage to use the fastest OpenCL device involve the following steps.

+Run the command:
+@example

+Note down the platform ID (@var{pidx}) and device ID (@var{didx}) of the first

 Note that the APIC frames must be written at the beginning, so the muxer will
 buffer the audio frames until it gets all the pictures. It is therefore advised
 to provide the pictures as soon as possible to avoid excessive buffering.
