This supports HMAC-MD5 and HMAC-SHA1 for now, other hashes are
simple to add.

In particular, make it consistent with the ffmpeg docs.

"analyzeduration" is not used to detect the input duration, but to
specify the max probe data duration. Fix option description and related
doc entry accordingly.

This allows to name an internal reference in the POD/MAN output.

Also fix a lavu version typo in APIchanges.

The paragraph is about what ffserver is not and where to look for other
information, but is pretty redundant and distracting, especially
considering the new organization of the documentation.

In particular, add some markup, fix empty line, and merge it with "How
does it work?" section.

This uses page duration instead of byte size to determine when to buffer
the page. Also, it tries to avoid continued pages by buffering the current
page if there are already packets in the page and adding the next packet
would require it to be continued on a new page. This can improve seeking
performance.

The default page duration is 1 second, which is much saner than filling
all page segments by default.

This allows reordering, duplication, and silencing of input channels.

It's obviously undesireable to blindly allocate memory based on
a damaged 'size' value, for example.

It's pretty much the best tool for the job, and it's what we
all use now anyway.

If a bug exists on the tracker, its ID should always be included
in fix messages.

Also, any relevant bug fixes should be CC'd to libav-stable, so
we can actually track what needs to be backported, instead of
just randomly combing the git history and old CVEs.

We obviously prefer git-send-email(1), and the disjointed nature
of the two statements was misleading.

Snow is a toy codec with no real-world use and horrible code.

This is a port of virtual dub's histogram equalization filter by Donald
A. Graft. Based on the work by Jérémy Tran <tran.jeremy.av@gmail.com>,
done for SOCIS 2012.

This is a port of the kerndeint filter (libmpcodecs/vf_kerndeint) by
Donal A. Graft (original avisynth plugin author), and is based on the
work by Jérémy Tran <tran.jeremy.av@gmail.com> done for SOCIS 2012.

Add a paragraph about MSVC and mention 24-bit FLAC encoding.

After making some blind tests on a small collection of music
samples for home usage. It turned out that the default cutoff
was too low.

The impact of filter_size was not clearly distinguishable (the
results were on the edge) with the music samples but turned out
to be clearly audible in some synthetic samples.

Thanks to Daniel for helping out with the listening tests.

Also rename the "enable_auto" field to "deint", to match the name of the
option.

Also add example showing cat piping images to ffmpeg.

Note that the linebreaks text codec option (but not the feature) has
been removed; its main goal was to allow demuxers to configure the text
decoder (and not meant to be used by users), but the AVOption are not a
viable solution. This is solved differently in this commit.
