18f43de964 doc/ffmpeg,ffmpeg-formats: avoid to mention ffmpeg options from formats.texi
Also extends documentation for timestamp related ffmpeg options, in order
to make more apparent the fact that muxer processing may change the
timestamps values.

cb2bd91413 ffmpeg: add the -canvas_size option.
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.

f185a040b0 doc/ffplay,ffmpeg: mention the corresponding negated option for -stats
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.

d11ac64ecf doc: replace '×' symbol with 'x'
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.

b448677e6e doc: remove inclusion of libav* documentation in tools
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.

7794ddeae3 doc/ffmpeg: do not show examples making use of the deprecated glob_sequence pattern type
The syntax of the 'glob_sequence' pattern type is explained in the image2

Also discourage the use of such deprecated pattern type by not showing
examples employing it.

type.

88fc1438c6 ffmpeg: insert bitmap subtitles as video in filters.
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.
