+ │ 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.
+
+   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.
+
+   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).
+
+   ┌────────────────────────────┐
+   │ 🔨  API Information         │

+
+     Important API changes since 2.3:
+
+       • 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.
+
+     Please refer to the doc/APIchanges file for more information.

+
+ ┌────────────────────────────┐
+ │ ⚠  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

-@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,
-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
-@end example
-
-@anchor{background task}
-@section How do I run ffmpeg as a background task?
-
-ffmpeg normally checks the console input, for entries like "q" to stop
-and "?" to give help, while performing operations. ffmpeg does not have a way of
-detecting when it is running as a background task.
-When it checks the console input, that can cause the process running ffmpeg
-in the background to suspend.
-
-To prevent those input checks, allowing ffmpeg to run as a background task,
-use the @url{ffmpeg.html#stdin-option, @code{-nostdin} option}
-in the ffmpeg invocation. This is effective whether you run ffmpeg in a shell
-or invoke ffmpeg in its own process via an operating system API.
-
-As an alternative, when you are running ffmpeg in a shell, you can redirect
-standard input to @code{/dev/null} (on Linux and macOS)
-or @code{NUL} (on Windows). You can do this redirect either
-on the ffmpeg invocation, or from a shell script which calls ffmpeg.
-
-For example:
-
-@example
-ffmpeg -nostdin -i INPUT OUTPUT
-@end example
-
-or (on Linux, macOS, and other UNIX-like shells):
-
-@example
-ffmpeg -i INPUT OUTPUT </dev/null
-@end example
-
-or (on Windows):
-
-@example
-ffmpeg -i INPUT OUTPUT <NUL
-@end example
-
-@section How do I prevent ffmpeg from suspending with a message like @emph{suspended (tty output)}?
-
-If you run ffmpeg in the background, you may find that its process suspends.
-There may be a message like @emph{suspended (tty output)}. The question is how
-to prevent the process from being suspended.
-
-For example:
-
-@example
-% ffmpeg -i INPUT OUTPUT &> ~/tmp/log.txt &
-[1] 93352
-%
-[1]  + suspended (tty output)  ffmpeg -i INPUT OUTPUT &>
-@end example
-
-The message "tty output" notwithstanding, the problem here is that
-ffmpeg normally checks the console input when it runs. The operating system
-detects this, and suspends the process until you can bring it to the
-foreground and attend to it.
-
-The solution is to use the right techniques to tell ffmpeg not to consult
-console input. You can use the
-@url{ffmpeg.html#stdin-option, @code{-nostdin} option},
-or redirect standard input with @code{< /dev/null}.
