@ -192,6 +192,39 @@ Specify the preset for matching stream(s).
@item -stats (@emph{global})
Print encoding progress/statistics. On by default.
@item -attach @var{filename} (@emph{output})
Add an attachment to the output file. This is supported by a few formats
like Matroska for e.g. fonts used in rendering subtitles. Attachments
are implemented as a specific type of stream, so this option will add
a new stream to the file. It is then possible to use per-stream options
on this stream in the usual way. Attachment streams created with this
option will be created after all the other streams (i.e. those created
with @code{-map} or automatic mappings).
Note that for Matroska you also have to set the mimetype metadata tag:
@example
avconv -i INPUT -attach DejaVuSans.ttf -metadata:s:2 mimetype=application/x-truetype-font out.mkv
@end example
(assuming that the attachment stream will be third in the output file).
@item -dump_attachment[:@var{stream_specifier}] @var{filename} (@emph{input,per-stream})
Extract the matching attachment stream into a file named @var{filename}. If
@var{filename} is empty, then the value of the @code{filename} metadata tag
will be used.
E.g. to extract the first attachment to a file named 'out.ttf':
@example
avconv -dump_attachment:t:0 out.ttf INPUT
@end example
To extract all attachments to files determined by the @code{filename} tag:
@example
avconv -dump_attachment:t "" INPUT
@end example
Technical note -- attachments are implemented as codec extradata, so this
option can actually be used to extract extradata from any stream, not just
attachments.
