Decode errors can happen with concatenated MP3s
with different formats.

Based on my MicroDVD->ASS conversion code from MPlayer
(sub/subassconvert.c).

Omitting the seconds has not worked for a long time, if ever.
Omitting the minutes too is just nonsensical for a duration
(it is indistinguishable from just seconds).

This moves the cpu flag parsing code from avconv to avutil so
it can be accessed elsewhere.

This is a new library for audio sample format, channel layout, and sample rate
conversion.

libschroedinger is the preferred way to decode Dirac video.

Add "prog" parameter value, and deprecate numeric values.

The functions operate on the sample level rather than the byte level and work
with all audio sample formats.

The native libavfilter hflip filter does the same thing.

Switch from changing global values to defining a separate C style
and add appropriate settings for indenting assignments that span
more than one line.

This is required for letting applications to create and destroy
AVFilterInOut structs in a convenient way.

It was ported to a native libavfilter filter.

Partially based on the port by Niel van der Westhuizen
<nielkie@gmail.com>, done for GCI 2010. Same output as the original
filter and as fast.

See thread:
Subject: [FFmpeg-devel] [PATCH] Port MPlayer 2xSaI filter to libavfilter
Date: Thu, 25 Nov 2010 01:31:24 +1000

Remove unused variable size from video_encode_example() function.

Fix GCC warning:
decoding_encoding.c:214:22: warning: unused variable ‘size’ [-Wunused-variable]

The header is part of the public API, in particular is used by
doc/examples/filtering_audio.c.

Based on a patch by Clément Bœsch <ubitux@gmail.com>

Address trac ticket #1153.

Makes more explicit that framecrc works at the packet level, also prefers
the term "packet" over "frame" when it makes sense.

Add mention to the pts and duration log fields, added in
d2afbd9a56.

Fix trac ticket #1159.

removelogo has been ported to libavfilter, and the wrapper was not
working.

The code is based on the remove-logo filter in MPlayer/libmpcodecs, by
Robert Edele, relicensed to LGPL with consent of the author.

Address trac issue #249.

* adapt examples to new syntax
* mention that glob chars need to be enabled by a preceding % char
* note that globbing will be performed if both a printf and globbing
  pattern would be possible judging from the input pattern

Also, use the new function in the AC-3 encoder.

Address trac ticket #1120.

The $(dir) function used to construct OBJDIRS includes a trailing slash
in the names returned, which GNU make 3.82 does not match to the
slash-less 'doc' in the documentation dependencies, causing parallel
build to fail.  Adding a slash fixes this and still works with make
3.81.

It is not entirely clear that whilst for width and height only an
expression needs to be provided, for interlace the option must
also be given.

It is also unclear that the default is non interlaced aware scaling.

Now that a documentation generator is built in the doc directory,
this is no longer necessary.  Fixes the Make warning:
Makefile:188: target `doc' given more than once in the same rule.
