mkvpropedit - Modify properties of existing Matroska files without a complete remux
SINOSSI
mkvpropedit [options] {source-filename} {actions}
DESCRIZIONE
This program analyses an existing Matroska file and modifies some of its properties. Then
it writes those modifications to the existing file. Among the properties that can be
changed are the segment information elements (e.g. the title) and the track headers (e.g.
the language code, 'default track' flag or the name).
Opzioni:
-l, --list-property-names
Lists all known and editable property names, their type (string, integer, boolean etc)
and a short description. The program exits afterwards. Therefore the source-filename
parameter does not have to be supplied.
-p, --parse-mode mode
Sets the parse mode. The parameter 'mode' can either be 'fast' (which is also the
default) or 'full'. The 'fast' mode does not parse the whole file but uses the meta
seek elements for locating the required elements of a source file. In 99% of all cases
this is enough. But for files that do not contain meta seek elements or which are
damaged the user might have to set the 'full' parse mode. A full scan of a file can
take a couple of minutes while a fast scan only takes seconds.
Actions that deal with track and segment info properties:
-e, --edit selector
Sets the Matroska file section (segment information or a certain track's headers) that
all following add, set and delete actions operate on. This option can be used multiple
times in order to make modifications to more than one element.
By default mkvpropedit(1) will edit the segment information section.
See the section about edit selectors for a full description of the syntax.
-a, --add name=value
Adds a property name with the value value. The property will be added even if such a
property exists already. Note that most properties are unique and cannot occur more
than once.
-s, --set name=value
Sets all occurrences of the property name to the value value. If no such property
exists then it will be added.
-d, --delete nome
Deletes all occurrences of the property name. Note that some properties are required
and cannot be deleted.
Actions that deal with tags and chapters:
-t, --tags selector:filename
Add or replace tags in the file with the ones from filename or remove them if filename
is empty. mkvpropedit(1) reads the same XML tag format that mkvmerge(1) reads as
well.
The selector must be one of the words all, global or track. For all mkvpropedit(1)
will replace or remove all tags in a file. With global only global tags will be
replaced or removed.
With track mkvpropedit(1) will replace tags for a specific track. Additionally the
tags read from filename will be assigned to the same track. The track is specified in
the same way edit selectors are specified (see below), e.g. --tags
track:a1:new-audio-tags.xml.
--add-track-statistics-tags
Calculates statistics for all tracks in a file and adds new statistics tags for them.
If the file already contains such tags then they'll be updated.
--delete-track-statistics-tags
Deletes all existing track statistics tags from a file. If the file doesn't contain
track statistics tags then it won't be modified.
-c, --chapters nomefile
Add or replace chapters in the file with the ones from filename or remove them if
filename is empty. mkvpropedit(1) reads the same XML and simple chapter formats that
mkvmerge(1) reads as well.
Actions for handling attachments:
--add-attachment nomefile
Adds a new attachment from filename.
If the option --attachment-name has been used prior to this option then its value is
used as the new attachment's name. Otherwise it is derived from filename.
If the option --attachment-mime-type has been used prior to this option then its value
is used as the new attachment's MIME type. Otherwise it is auto-detected from the
content of filename.
If the option --attachment-description has been used prior to this option then its
value is used as the new attachment's description. Otherwise no description will be
set.
If the option --attachment-uid has been used prior to this option then its value is
used as the new attachment's UID. Otherwise a random UID will be generated
automatically.
--replace-attachment selector:filename
Replaces one or more attachments that match selector with the file filename. If more
than one existing attachment matches selector then all of their contents will be
replaced by the content of filename.
The selector can have one of four forms. They're explained below in the section
attachment selectors.
If the option --attachment-name has been used prior to this option then its value is
set as the new name for each modified attachment. Otherwise the names aren't changed.
If the option --attachment-mime-type has been used prior to this option then its value
is set as the new MIME type for each modified attachment. Otherwise the MIME types
aren't changed.
If the option --attachment-description has been used prior to this option then its
value is set as the new description for each modified attachment. Otherwise the
descriptions aren't changed.
If the option --attachment-uid has been used prior to this option then its value is
set as the new UID for each modified attachment. Otherwise the UIDs aren't changed.
--update-attachment selector
Sets the properties of one or more attachments that match selector. If more than one
existing attachment matches selector then all of their properties will be updated.
The selector can have one of four forms. They're explained below in the section
attachment selectors.
If the option --attachment-name has been used prior to this option then its value is
set as the new name for each modified attachment. Otherwise the names aren't changed.
If the option --attachment-mime-type has been used prior to this option then its value
is set as the new MIME type for each modified attachment. Otherwise the MIME types
aren't changed.
If the option --attachment-description has been used prior to this option then its
value is set as the new description for each modified attachment. Otherwise the
descriptions aren't changed.
If the option --attachment-uid has been used prior to this option then its value is
set as the new UID for each modified attachment. Otherwise the UIDs aren't changed.
--delete-attachment selector
Deletes one or more attachments that match selector.
The selector can have one of four forms. They're explained below in the section
attachment selectors.
Options for attachment actions:
--attachment-name name
Sets the name to use for the following --add-attachment or --replace-attachment
operation.
--attachment-mime-type mime-type
Sets the MIME type to use for the following --add-attachment or --replace-attachment
operation.
--attachment-description description
Sets the description to use for the following --add-attachment or --replace-attachment
operation.
--enable-legacy-font-mime-types
Enables the use of legacy MIME types for certain types of font attachments. For
example, 'application/x-truetype-font' will be used for TrueType fonts instead of
'fonts/ttf'.
This affects both adding new attachments and replacing existing attachments, but only
if the new MIME type isn't specified. Other existing attachments aren't changed.
The affected MIME types are 'font/sfnt', 'font/ttf' and 'font/collection' which are
all mapped to 'application/x-truetype-fonts' and 'font/otf' which is mapped to
'application/vnd.ms-opentype'.
Altre opzioni:
--disable-language-ietf
Normally when the user requests changes to the 'language' track header property,
mkvpropedit(1) will apply the same change to the new LanguageIETF track header element
in addition to the legacy Language element. If this option is used, the change is only
applied to the legacy Language element.
This option does not affect changes requested via the 'language-ietf' track header
property.
--normalize-language-ietf mode
Enables normalizing all IETF BCP 47 language tags to either their canonical form with
mode 'canonical', to their extended language subtags form with mode 'extlang' or turns
it off with mode 'off'. By default normalization to the canonical form is applied.
In the canonical form all subtags for which preferred values exist are replaced by
those preferred values. This converts e.g. 'zh-yue-jyutping' to 'yue-jyutping' or
'fr-FX' to 'fr-FR'.
For the extended language subtags form the canonical form is built first. Afterwards
all primary languages for which an extended language subtag exists are replaced by
that extended language subtag and its prefix. This converts e.g. 'yue-jyutping' back
to 'zh-yue-jyutping' but has no effect on 'fr-FR' as 'fr' is not an extended language
subtag.
This normalization is only applied to elements that are actually changed:
• When editing track headers only those track language elements that are set via
edit specifications are affected. Languages of tracks that aren't edited aren't
changed. Editing a track but setting only properties other than the language won't
affect the language either.
• When editing chapters all language elements of all chapter elements are affected
as existing chapters are always fully replaced.
• When editing tags only the language elements of the tags that are actually
replaced are affected. For example, when you replace global tags then existing
track tags aren't affected.
The best way to normalize all existing language tags in a file is to remux it with
mkvmerge(1) and set its '--normalize-language-ietf' option to the desired mode.
--command-line-charset character-set
Imposta il set caratteri per convertire le stringhe date dalla riga di comando. Di
base è impostato dalla lingua di sistema.
--output-charset character-set
Imposta il set caratteri per le stringhe convertite date in output. Di base è
impostato dalla lingua di sistema.
-r, --redirect-output file-name
Writes all messages to the file file-name instead of to the console. While this can be
done easily with output redirection there are cases in which this option is needed:
when the terminal reinterprets the output before writing it to a file. The character
set set with --output-charset is honored.
--ui-language code
Forza le traduzioni per la lingua code da usare (per esempio: 'it_IT' per le
traduzioni in Italiano). Immettendo 'list' come code mostrerà la lista delle
traduzioni disponibili.
--abort-on-warnings
Indica al programma di interrompere dopo il primo avviso. Il codice di uscita del
programma sarà 1.
--debug argomento
Abilita il debug per una funzionalità. Questa opzione è utile per gli sviluppatori.
--engage funzionalità
Turn on experimental features. A list of available features can be requested with
mkvpropedit --engage list. These features are not meant to be used in normal
situations.
--gui-mode
Mostra la GUI (interfaccia grafica). In questa modalità a terminale ci saranno delle
righe specifiche su cosa sta succedendo. Questi messaggi seguiranno il formato
'#GUI#messaggio'. Il messaggio può essere seguito da delle coppie chiave/valore come
'#GUI#messaggio#chiave1=valore1#chiave2=valore2...'. Né i messaggi e né le chiavi
saranno mai tradotte e l'output sarà sempre in Inglese.

@options-file.json
Legge gli argomenti a riga di comando dal file options-file. Per una spiegazione
completa sul formato supportato vedere la sezione "File di Opzioni" nel manuale di
mkvmerge(1).
EDIT SELECTORS
The --edit option sets the Matroska file section (segment information or a certain track's
headers) that all following add, set and delete actions operate on. This stays valid until
the next --edit option is found. The argument to this option is called the edit selector.
By default mkvpropedit(1) will edit the segment information section.
Informazione segmento
The segment information can be selected with one of these three words: 'info',
'segment_info' or 'segmentinfo'. It contains properties like the segment title or the
segment UID.
Intestazione tracce
Track headers can be selected with a slightly more complex selector. All variations start
with 'track:'. The track header properties include elements like the language code,
'default track' flag or the track's name.
track:n
If the parameter n is a number then the nth track will be selected. The track order is
the same that mkvmerge(1)'s --identify option outputs.
Numbering starts at 1.
track:tn
If the parameter starts with a single character t followed by a n then the nth track
of a specific track type will be selected. The track type parameter t must be one of
these four characters: 'a' for an audio track, 'b' for a button track, 's' for a
subtitle track and 'v' for a video track. The track order is the same that
mkvmerge(1)'s --identify option outputs.
Numbering starts at 1.
track:=uid
If the parameter starts with a '=' followed by a number uid, the track whose track UID
element equals the given uid will be selected. Track UIDs can be obtained with
mkvinfo(1).
track:@number
If the parameter starts with a '@' followed by a number number, the track whose track
number element equals this number will be selected. Track numbers can be obtained with
mkvinfo(1).
Note
Due to the nature of the track edit selectors it is possible that several selectors
actually match the same track headers. In such cases all actions for those edit selectors
will be combined and executed in the order in which they're given on the command line.
SELETTORI ALLEGATO
An attachment selector is used with the two actions --replace-attachment and
--delete-attachment. It can have one of the following four forms:
1. Selection by attachment ID. In this form the selector is simply a number, the
attachment's ID as output by mkvmerge(1)'s identification command.
2. Selection by attachment UID (unique ID). In this form the selector is the equal sign =
followed by a number, the attachment's unique ID as output by mkvmerge(1)'s verbose
identification command.
3. Selection by attachment name. In this form the selector is the literal word name:
followed by the existing attachment's name. If this selector is used with
--replace-attachment then colons within the name to match must be escaped as \c.
4. Selection by MIME type. In this form the selector is the literal word mime-type:
followed by the existing attachment's MIME type. If this selector is used with
--replace-attachment then colons within the MIME type to match must be escaped as \c.
LANGUAGE HANDLING
mkvpropedit(1) mostly tries to do the right thing by default. Therefore changes to the
language property will cause mkvpropedit(1) to apply the same change to both the new
"LanguageIETF" element as well as the old "Language" element similar to how mkvmerge(1)
applies the language to both elements. For example, when using mkvpropedit movie.mkv
--edit track:2 --set language=zh-TW the "LanguageIETF" element will be set to zh-TW and
the old "Language" element to chi.
Additionally there's a new track header property named language-ietf that can be set or
removed. Changes to this property only apply to the new "LanguageIETF" track header
element. A caveat is that the old "Language" track header element is a mandatory element
in Matroska — meaning even if it isn't present in the file it still has an implied value.
When the user only sets the language-ietf property but not the language property,
mkvpropedit(1) will therefore add the old "Language" element in certain cases & set it to
und (meaning "undetermined") as the user didn't specify a value for it.
When reading XML chapter or tag files mkvpropedit(1) works like mkvmerge(1) does.
The creation of the new elements can be disabled completely with the command-line option
`--disable-language-ietf` which operates on all three new elements.
You can chose the normalization method applied to extended language sub-tags with the
parameter --normalize-language-ietf.
ESEMPI
The following example edits a file called 'movie.mkv'. It sets the segment title and
modifies the language code of an audio and a subtitle track. Note that this example can be
shortened by leaving out the first --edit option because editing the segment information
element is the default for all options found before the first --edit option anyway.
$ mkvpropedit movie.mkv --edit info --set "title=The movie" --edit track:a1 --set language=fre --edit track:a2 --set language=ita
The second example removes the 'default track flag' from the first subtitle track and sets
it for the second one. Note that mkvpropedit(1), unlike mkvmerge(1), does not set the
'default track flag' of other tracks to '0' if it is set to '1' for a different track
automatically.
$ mkvpropedit movie.mkv --edit track:s1 --set flag-default=0 --edit track:s2 --set flag-default=1
Replacing the tags for the second subtitle track in a file looks like this:
$ mkvpropedit movie.mkv --tags track:s2:new-subtitle-tags.xml
Removing all tags requires leaving out the file name:
$ mkvpropedit movie.mkv --tags all:
Replacing the chapters in a file looks like this:
$ mkvpropedit movie.mkv --chapters new-chapters.xml
Removing all chapters requires leaving out the file name:
$ mkvpropedit movie.mkv --chapters ''
Adding a font file (Arial.ttf) as an attachment:
$ mkvpropedit movie.mkv --add-attachment Arial.ttf
Adding a font file (89719823.ttf) as an attachment and providing some information as it
really is just Arial:
$ mkvpropedit movie.mkv --attachment-name Arial.ttf --attachment-description 'The Arial font as a TrueType font' --attachment-mime-type application/x-truetype-font --add-attachment 89719823.ttf
Replacing one attached font (Comic.ttf) file with another one (Arial.ttf):
$ mkvpropedit movie.mkv --attachment-name Arial.ttf --attachment-description 'The Arial font as a TrueType font' --replace-attachment name:Comic.ttf:Arial.ttf
Deleting the second attached file, whatever it may be:
$ mkvpropedit movie.mkv --delete-attachment 2
Deleting all attached fonts by MIME type:
$ mkvpropedit movie.mkv --delete-attachment mime-type:application/x-truetype-font
CODICI DUSCITA
mkvpropedit(1) esce con uno di tre codici di uscita:
• 0 -- This exit code means that the modification has completed successfully.
• 1 -- In this case mkvpropedit(1) has output at least one warning, but the modification
did continue. A warning is prefixed with the text 'Warning:'. Depending on the issues
involved the resulting files might be ok or not. The user is urged to check both the
warning and the resulting files.
• 2 -- This exit code is used after an error occurred. mkvpropedit(1) aborts right
after outputting the error message. Error messages range from wrong command line
arguments over read/write errors to broken files.

VARIABILI DAMBIENTE
mkvpropedit(1) uses the default variables that determine the system's locale (e.g. LANG
and the LC_* family). Additional variables:
MKVPROPEDIT_DEBUG, MKVTOOLNIX_DEBUG and its short form MTX_DEBUG
The content is treated as if it had been passed via the --debug option.
MKVPROPEDIT_ENGAGE, MKVTOOLNIX_ENGAGE and its short form MTX_ENGAGE
The content is treated as if it had been passed via the --engage option.
