-              └────────────────────────────────────────┘
+   The FFmpeg Project proudly presents FFmpeg 2.4 "Fresnel", just 2 months

+   is a bit short this time.
 
-   The FFmpeg Project proudly presents FFmpeg 2.8 "Feynman", about 3
-   months after the release of FFmpeg 2.7.
+   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.

-You can also use @command{pkg-config} from the host environment by

-In that case, you must point @command{pkg-config} to the correct directories

-As an intermediate solution, you can place in your cross-compilation

-@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

-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

-Do not forget to examine carefully the original video to check whether the

-
-For example, to fix a badly encoded EGA capture, use the following commands,

+@itemize
+@item
+For streaming at very low bitrates, use a low frame rate
+and a small GOP size. This is especially true for RealVideo where
+the Linux player does not seem to be very fast, so it can miss
+frames. An example is:
+
+@example
+ffmpeg -g 3 -r 3 -t 10 -b:v 50k -s qcif -f rv10 /tmp/b.rm
+@end example
+
+@item
+The parameter 'q' which is displayed while encoding is the current
+quantizer. The value 1 indicates that a very good quality could
+be achieved. The value 31 indicates the worst quality. If q=31 appears
+too often, it means that the encoder cannot compress enough to meet
+your bitrate. You must either increase the bitrate, decrease the
+frame rate or decrease the frame size.
+
+@item
+If your computer is not fast enough, you can speed up the
+compression at the expense of the compression ratio. You can use
+'-me zero' to speed up motion estimation, and '-g 0' to disable
+motion estimation completely (you have only I-frames, which means it
+is about as good as JPEG compression).
+
+@item
+To have very low audio bitrates, reduce the sampling frequency
+(down to 22050 Hz for MPEG audio, 22050 or 11025 for AC-3).
+
+@item
+To have a constant quality (but a variable bitrate), use the option
+'-qscale n' when 'n' is between 1 (excellent quality) and 31 (worst
+quality).

+A preset file contains a sequence of @var{option=value} pairs, one for

+Preset files are specified with the @code{pre} option, this option takes a
