Force re-generation of the manuals when an included file is modified.
The current dependency generation system is enable to track nested
inclusions.
The drawback is that the files will be generated even when there is no
strict need (for example if filters.texi is modified, ffmpeg.1 is
rebuilt), thus it trades a false negative with a false positive.
We used to use 'filtergraph' or 'filter graph' randomly.
'filtergraph' was chosen due to having 57 occurrences in
the documentation, whereas 'filter graph' had only 19.

Also extends documentation for timestamp related ffmpeg options, in order
to make more apparent the fact that muxer processing may change the
timestamps values.
Allows, amongst other things, to override the size guessed
by the sub2video hack.
Note: the -s option could have more or less the same semantic,
but it receives a special treatment by the options system.
This helps lazy users who didn't read the part about boolean options, in
case they grep for "-nostats".
-stdin and -stats are the only booleans option enabled by default. This
is a partial fix for Trac ticket #2332, a complete overhaul of boolean
options documentation is probably overkill.
Non-ascii chars are not correctly rendered in both MAN and HTML output or
may even cause compilation failure. Thus avoid to use them until we find
a satisfying way to deal with them.
Fix trac ticket #2243.
This shrinks the tool manuals to a manageable size. Relevant manuals are
referenced in the "See Also" chapter.
Overall documentation inclusion should still be possible through the use
of a conditional variable set during configuration time, if someone feels
the need for a huge-wall-of-text-fashioned manual.
Add more references, and generate alternative variants for HTML and POD
output. In particular, this allows to render a "See Also" chapter in the
HTML output.
The syntax of the 'glob_sequence' pattern type is explained in the image2
manual section, so there is no need to replicate it here.
Also discourage the use of such deprecated pattern type by not showing
examples employing it.
Replace the syntax explanation with an use example of the 'glob' pattern
type.
With this feature, it becomes possible to perform commonly
requested tasks, such as hardcoding bitmap subtitles.
This will be reverted once libavfilter has proper support
for subtitles. All the changes have the string "sub2video"
in them, it makes it easy to spot the parts.
Allows to disable interaction from standard input.
Useful, for example, if ffmpeg is in the background process group.
Roughly the same result can be achieved with "ffmpeg ... < /dev/null"
but it requires a shell.
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).
