-              └───────────────────────────────────────┘
+   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.
 
-   The FFmpeg Project proudly presents FFmpeg 3.4 "Cantor", about 6
-   months after the release of FFmpeg 3.3.
+   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.
 
-   A complete Changelog is available at the root of the project, and the
-   complete Git history on http://source.ffmpeg.org.
+   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).
 
-   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.

-//! Context-locking: to facilitate multi-threaded implementations, the following 4 functions
-//! provide a simple mutex-style host synchronization. If a non-NULL context is specified
-//! in CUVIDDECODECREATEINFO, the codec library will acquire the mutex associated with the given
-//! context before making any cuda calls.
-//! A multi-threaded application could create a lock associated with a context handle so that
-//! multiple threads can safely share the same cuda context:
-//!  - use cuCtxPopCurrent immediately after context creation in order to create a 'floating' context
-//!    that can be passed to cuvidCtxLockCreate.
-//!  - When using a floating context, all cuda calls should only be made within a cuvidCtxLock/cuvidCtxUnlock section.
-//!
-//! NOTE: This is a safer alternative to cuCtxPushCurrent and cuCtxPopCurrent, and is not related to video
-//! decoder in any way (implemented as a critical section associated with cuCtx{Push|Pop}Current calls).

-  "flags2" decoding option now allows the flag "ass_ro_flush_noop" preventing

-
-2016-02-26 - 2941282 - lavc 57.26.100 - avcodec.h
-  Add a "sub_text_format" subtitles decoding option allowing the values "ass"
-  (recommended) and "ass_with_timings" (not recommended, deprecated, default).
-  The default value for this option will change to "ass" at the next major
-  libavcodec version bump.
-
-  The current default is "ass_with_timings" for compatibility. This means that
-  all subtitles text decoders currently still output ASS with timings printed
-  as strings in the AVSubtitles.rects[N]->ass fields.
-
-  Setting "sub_text_format" to "ass" allows a better timing accuracy (ASS
-  timing is limited to a 1/100 time base, so this is relevant for any subtitles
-  format needing a bigger one), ease timing adjustments, and prevents the need
-  of removing the timing from the decoded string yourself. This form is also
-  known as "the Matroska form". The timing information (start time, duration)
-  can be found in the AVSubtitles fields.

-
-Be friendly and respectful towards others and third parties.
-Treat others the way you yourself want to be treated.
-
-Be considerate. Not everyone shares the same viewpoint and priorities as you do.
-Different opinions and interpretations help the project.
-Looking at issues from a different perspective assists development.
-
-Do not assume malice for things that can be attributed to incompetence. Even if
-it is malice, it's rarely good to start with that as initial assumption.
-
-Stay friendly even if someone acts contrarily. Everyone has a bad day

-If you yourself have a bad day or are angry then try to take a break and reply
-once you are calm and without anger if you have to.

-Try to help other team members and cooperate if you can.

-
-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

-@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{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,
