-   The FFmpeg Project proudly presents FFmpeg 2.3 "Mandelbrot", a major
-   release with all the great features committed during the three-month period
-   since the release of FFmpeg 2.2.
+   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.
 
-   In this release, there are lots of internal overhauls that make FFmpeg a
-   more accessible project for new developers. Many important new features
-   like QTKit and AVFoundation input devices are committed. Contributions done
-   by Libav such as a new native Opus decoder are also merged.
+   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.
 
-   Because of the increasing difficulty to maintain and lack of maintainers,
-   we are very sorry to say that we have removed all Blackfin and SPARC
-   architecture assembly optimizations with the cleanups done. If you are
-   interested in maintaining optimization for these two architecture, feel
-   free to contact us and we will restore the code!
-
-   Since this release, the traditional Changelog file is upgraded to this
-   modern-looking release note. Old changelogs are moved to doc/Changelog.old.
-
-   Enjoy!
+   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).

-   ┌────────────────────────────┐
-   │ New Optimization           │
-   └────────────────────────────┘
+       • 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.
 
-     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.

+@item start_periods
+This value is used to indicate if audio should be trimmed at beginning of

+finds non-silence. Normally, when trimming silence from beginning of audio

+as silence and trimmed off. Default value is @code{0}.

+@item start_threshold

+audio, a value of @code{0} may be fine but for audio recorded from analog,
+you may wish to increase the value to account for background noise.

+
+@item stop_periods
+Set the count for trimming silence from the end of audio.
+To remove silence from the middle of a file, specify a @var{stop_periods}
+that is negative. This value is then threated as a positive value and is
+used to indicate the effect should restart processing as specified by
+@var{start_periods}, making it suitable for removing periods of silence
+in the middle of the audio.
+Default value is @code{0}.
+
+@item stop_duration
+Specify a duration of silence that must exist before audio is not copied any

+Correct radial lens distortion
+
+This filter can be used to correct for radial distortion as can result from the use
+of wide angle lenses, and thereby re-rectify the image. To find the right parameters
+one can use tools available for example as part of opencv or simply trial-and-error.
+To use opencv use the calibration sample (under samples/cpp) from the opencv sources
+and extract the k1 and k2 coefficients from the resulting matrix.
+
+Note that effectively the same filter is available in the open-source tools Krita and
+Digikam from the KDE project.
+
+In contrast to the @ref{vignette} filter, which can also be used to compensate lens errors,
+this filter corrects the distortion of the image, whereas @ref{vignette} corrects the
+brightness distribution, so you may want to use both filters together in certain
+cases, though you will have to take care of ordering, i.e. whether vignetting should
+be applied before or after lens correction.
