--add-metadata Write metadata to the video file
|

--no-add-metadata Do not write metadata (default)
|

--parse-metadata FIELD:FORMAT Parse additional metadata like title/artist
|
||||
from other fields. Give field name to
|
||||
extract data from, and format of the field
|
||||
seperated by a ":". Either regular
|
||||
expression with named capture groups or a
|
||||
similar syntax to the output template can
|
||||
also be used. The parsed parameters replace
|
||||
any existing values and can be use in
|
||||
output template. This option can be used
|
||||
multiple times. Example: --parse-metadata
|
||||
"title:%(artist)s - %(title)s" matches a
|
||||
title like "Coldplay - Paradise". Example
|
||||
(regex): --parse-metadata
|
||||
from other fields. Give a template or field
|
||||
name to extract data from and the format to
|
||||
interpret it as, seperated by a ":". Either
|
||||
regular expression with named capture
|
||||
groups or a similar syntax to the output
|
||||
template can be used for the FORMAT.
|
||||
Similarly, the syntax for output template
|
||||
can be used for FIELD to parse the data
|
||||
from multiple fields. The parsed parameters
|
||||
replace any existing values and can be used
|
||||
in output templates. This option can be
|
||||
used multiple times. Example: --parse-
|
||||
metadata "title:%(artist)s - %(title)s"
|
||||
matches a title like "Coldplay - Paradise".
|
||||
Example: --parse-metadata "%(series)s
|
||||
%(episode_number)s:%(title)s" sets the
|
||||
title using series and episode number.
|
||||
Example (regex): --parse-metadata
|
||||
"description:Artist - (?P<artist>.+?)"
|

--xattrs Write metadata to the video file's xattrs
