SZABLON LINII KOMEND

       mkvextract {source-filename} {mode1} [options] [extraction-spec1] [mode2] [options]
                  [extraction-spec2] [...]

OPIS

This program extracts specific parts from a Matroska file to other useful formats. The
first argument is the name of the source file which must be a Matroska file.

All other arguments either switch to a certain extraction mode, change options for the
currently active mode or specify what to extract into which file. Multiple modes can be
used in the same invocation of mkvextract allowing the extraction of multiple things in a
single pass. Most options can only be used in certain modes with a few options applying to
all modes.

Currently supported is the extraction of tracks, tags, attachments, chapters, CUE sheets,
timestamps and cues.

Podstawowe opcje
The following options are available in all modes and only described once in this section.

-f, --parse-fully
Sets the parse mode to 'full'. The default 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 use this mode. A full scan of a file can take
a couple of minutes while a fast scan only takes seconds.

--command-line-charset zestaw-znaków
Sets the character set to convert strings given on the command line from. It defaults
to the character set given by system's current locale.

--output-charset zestaw-znaków
Sets the character set to which strings are converted that are to be output. It
defaults to the character set given by system's current locale.

-r, --redirect-output nazwa-pliku
Zapisuje wszystkie powiadomienia do pliku nazwa-pliku zamiast do konsoli. Podczas
kiedy może być to robione łatwo z przekierowaniem wyjścia, są przypadki kiedy ta opcja
właśnie jest potrzebna: kiedy terminal ponownie interpretuje plik wyjściowy przed
zapisaniem do pliku. Uznawany będzie zestaw znaków ustawiony z opcją --output-charset.

--flush-on-close
Tells the program to flush all data cached in memory to storage when closing files
opened for writing. This can be used to prevent data loss on power outages or to
circumvent certain problems in the operating system or drivers. The downside is that
multiplexing will take longer as mkvmerge will wait until all data has been written to
the storage before exiting. See issues #2469 and #2480 on the MKVToolNix bug tracker
for in-depth discussions on the pros and cons.

--ui-language kod
Forces the translations for the language code to be used (e.g. 'de_DE' for the German
translations). Entering 'list' as the code will cause the program to output a list of
available translations.

--abort-on-warnings
Tells the program to abort after the first warning is emitted. The program's exit code
will be 1.

--debug temat
Włącza debugowanie dla konkretnej funkcji. Ta opcja jest użyteczna tylko dla
deweloperów.

--engage funkcja
Włącza eksperymentalne funkcjonalności. Lista dostepnych funkcjonalności jest dostępna
po uruchomieniu komendy mkvextract --engage list. Te funkcjonalności nie powinny być
używane w normalnych sytuacjach.

--gui-mode
Turns on GUI mode. In this mode specially-formatted lines may be output that can tell
a controlling GUI what's happening. These messages follow the format '#GUI#message'.
The message may be followed by key/value pairs as in
'#GUI#message#key1=value1#key2=value2...'. Neither the messages nor the keys are ever
translated and always output in English.

-v, --verbose
Be verbose and show all the important Matroska elements as they're read.

-h, --help
Pokazuje informacje o sposobie użycia opcji i zamyka się.

-V, --version
Pokazuje informację o wersji i zamyka się.

@options-file.json
Reads additional command line arguments from the file options-file. For a full
explanation on the supported formats for such files see the section called "Option
files" in the mkvmerge(1) man page.

Tryb wyodrębniania ścieżek
Syntax: mkvextract source-filename tracks [options] TID1:dest-filename1
[TID2:dest-filename2 ...]

The following command line options are available for each track in the 'tracks' extraction
mode. They have to appear in front of the track specification (see below) they should be
applied to.

-c zestaw-znaków
Sets the character set to convert the next text subtitle track to. Only valid if the
next track ID targets a text subtitle track. It defaults to UTF-8.

--blockadd poziom
Keep only the BlockAdditions up to this level. The default is to keep all levels. This
option only affects certain kinds of codecs like WAVPACK4.

--cuesheet
Causes mkvextract(1) to extract a CUE sheet from the chapter information and tag data
for the following track into a file whose name is the track's output name with '.cue'
appended to it.

--raw
Extracts the raw data into a file without any container data around it. Unlike the
--fullraw flag this flag does not cause the contents of the CodecPrivate element to be
written to the file. This mode works with all CodecIDs, even the ones that
mkvextract(1) doesn't support otherwise, but the resulting files might not be usable.

--fullraw
Extracts the raw data into a file without any container data around it. The contents
of the CodecPrivate element will be written to the file first if the track contains
such a header element. This mode works with all CodecIDs, even the ones that
mkvextract(1) doesn't support otherwise, but the resulting files might not be usable.

TID:nazwa
Causes extraction of the track with the ID TID into the file outname if such a track
exists in the source file. This option can be given multiple times. The track IDs are
the same as the ones output by mkvmerge(1)'s --identify option.

Each output name should be used only once. The exception are RealAudio and RealVideo
tracks. If you use the same name for different tracks then those tracks will be saved
in the same file. Example:

$ mkvextract input.mkv tracks 0:video.h264 2:output-two-vobsub-tracks.idx 3:output-two-vobsub-tracks.idx

Tryb wyodrębniania załączników
Syntax: mkvextract source-filename attachments [options] AID1:outname1 [AID2:outname2 ...]

AID:nazwa
Causes extraction of the attachment with the ID AID into the file outname if such an
attachment exists in the source file. If the outname is left empty then the name of
the attachment inside the source Matroska file is used instead. This option can be
given multiple times. The attachment IDs are the same as the ones output by
mkvmerge(1)'s --identify option.

Tryb wyodrębniania rozdziałów
Syntax: mkvextract source-filename chapters [options] output-filename.xml

-s, --simple
Exports the chapter information in the simple format used in the OGM tools
(CHAPTER01=..., CHAPTER01NAME=...). In this mode some information has to be discarded.
Default is to output the chapters in XML format.

--simple-language language
If the simple format is enabled then mkvextract(1) will only output a single entry for
each chapter atom encountered even if a chapter atom contains more than one chapter
name. By default mkvextract(1) will use the first chapter name found for each atom
regardless of its language.

Using this option allows the user to determine which chapter names are output if atoms
contain more than one chapter name. The language parameter must be an ISO 639-1 or ISO
639-2 code.

The chapters are written to specified output file. By default the XML format understood by
mkvmerge(1) is used. If no chapters are found in the file, the output file is not created.

Tags extraction mode
Syntax: mkvextract source-filename tags [options] output-filename.xml

The tags are written to specified output file in the XML format understood by mkvmerge(1).
If no tags are found in the file, the output file is not created.

Tryb wyodrębniania arkuszy Cue
Syntax: mkvextract source-filename cuesheet [options] output-filename.cue

The cue sheet is written to specified output file. If no chapters or tags are found in the
file, the output file is not created.

Tryb wyodrębniania kodów czasowych
Syntax: mkvextract source-filename timestamps_v2 [options] TID1:dest-filename1
[TID2:dest-filename2 ...]

TID:nazwa
Causes extraction of the timestamps for the track with the ID TID into the file
outname if such a track exists in the source file. This option can be given multiple
times. The track IDs are the same as the ones output by mkvmerge(1)'s --identify
option.

Przykład:

$ mkvextract input.mkv timestamps_v2 1:ts-track1.txt 2:ts-track2.txt

Tryb wyodrębniania indeksu cue
Syntax: mkvextract source-filename cues [options] TID1:dest-filename1 [TID2:dest-filename2
...]

TID:docelowa-nazwapliku
Causes extraction of the cues for the track with the ID TID into the file outname if
such a track exists in the source file. This option can be given multiple times. The
track IDs are the same as the ones output by mkvmerge(1)'s --identify option and not
the numbers contained in the CueTrack element.

The format output is a simple text format: one line per CuePoint element with key=value
pairs. If an optional element is not present in a CuePoint (e.g. CueDuration) then a dash
will be output as the value.

Przykład:

timestamp=00:00:13.305000000 duration=- cluster_position=757741 relative_position=11

The possible keys are:

timestamp
The cue point's timestamp with nanosecond precision. The format is HH:MM:SS.nnnnnnnnn.
This element is always set.

duration
The cue point's duration with nanosecond precision. The format is HH:MM:SS.nnnnnnnnn.

cluster_position
The absolute position in bytes inside the Matroska file where the cluster containing
the referenced element starts.

Uwaga
Inside the Matroska file the CueClusterPosition is relative to the segment's data
start offset. The value output by mkvextract(1)'s cue extraction mode, however,
contains that offset already and is an absolute offset from the beginning of the
file.

relative_position
The relative position in bytes inside the cluster where the BlockGroup or SimpleBlock
element the cue point refers to starts.

Uwaga
Inside the Matroska file the CueRelativePosition is relative to the cluster's data
start offset. The value output by mkvextract(1)'s cue extraction mode, however, is
relative to the cluster's ID. The absolute position inside the file can be
calculated by adding cluster_position and relative_position.

Przykład:

$ mkvextract input.mkv cues 1:cues-track1.txt 2:cues-track2.txt

PRZYKŁADY

       Extracting both chapters and tags in their respective XML formats at the same time:

           $ mkvextract movie.mkv chapters movie-chapters.xml tags movie-tags.xml

       Extracting a couple of tracks and their respective timestamps at the same time:

           $ mkvextract "Another Movie.mkv" tracks 0:video.h265 "1:main audio.aac" "2:director's comments.aac" timestamps_v2 "0:timestamps video.txt" "1:timestamps main audio.txt" "2:timestamps director's comments.txt"

       Extracting chapters in the Ogg/OGM format and re-encoding a text subtitle track to another
       character set:

           $ mkvextract "My Movie.mkv" chapters --simple "My Chapters.txt" tracks -c MS-ANSI "2:My Subtitles.srt"

for the output file name. The following track types are supported at the moment:

A_AAC/MPEG2/*, A_AAC/MPEG4/*, A_AAC
Wszystkie pliki AAC będą zapisane do plików AAC z nagłówkami ADTS przed każdym
pakietem. Nagłówki ADTS nie będą zawierać niewspieranego pola emfazy.

A_AC3, A_EAC3
These will be extracted to raw AC-3 files.

A_ALAC
Ścieżki ALAC będą zapisane jako pliki CAF.

A_DTS
These will be extracted to raw DTS files.

A_FLAC
Ścieżki FLAC będą zapisane do surowych plików FLAC.

A_TRUEHD, A_MLP
These will be extracted to raw TrueHD/MLP files.

A_TTA1
Ścieżki TrueAudiobędą zapisane jako pliki TTA. Proszę zauważyć, że w wyniku
ograniczonej precyzji formatu Matroska, wyodrębnione nagłówki plików będą miały inne
dwa pola: data_length (łączna liczba sampli w pliku) i CRC.

A_VORBIS
Dźwięk Vorbis będzie zapisany do pliku OggVorbis.

A_WAVPACK4
Ścieżki WavPack będą zapisane jako pliki WV.

S_HDMV/PGS
Napisy PGS będą zapisane jako pliki SUP.

S_HDMV/TEXTST
TextST subtitles will be written as a special file format invented for mkvmerge(1) and
mkvextract(1).

S_KATE
Ścieżki Kate będą zapisane do kontenera Ogg.

S_TEXT/SSA, S_TEXT/ASS, S_SSA, S_ASS
Napisy tekstowe SSA i ASS będą zapisane jako pliki odpowiednio SSA/ASS.

S_TEXT/UTF8, S_TEXT/ASCII
Proste napisy tekstowe będą zapisane jako pliki SRT.

S_VOBSUB
Napisy VobSub będą zapisane jako pliki SUB razem z odpowiednimi plikami indeksu IDX.

V_MPEG4/ISO/AVC
Ścieżki obrazu H.264 / AVC będą zapisane jako ścieżki surowe (dane podstawowe) H.264,
które mogą być później przetwarzane np. przez MP4Box z pakietu GPAC.

V_MPEG4/ISO/HEVC
H.265 / HEVC video tracks are written to H.265 elementary streams which can be
processed further with e.g. MP4Box from the GPAC package.

V_MS/VFW/FOURCC
Ścieżki obrazu ze stałym FPS mające taki CodecID są zapisywane do plików AVI.

V_REAL/*
Ścieżki RealVideo będą zapisane jako pliki RealMedia.

V_THEORA
Ścieżki Theora będą zapisane do kontenera Ogg

V_VP8, V_VP9
VP8 / VP9 ścieżki są zapisywane do plików IVF.

Tagi
Tagi są konwertowane do formatu XML. Jest to taki sam format jaki mkvmerge(1)
obsługuje w plikach wejściowych.

Załączniki
Załączniki są zapisywane do pliku wyjściowego takie jakie są. Żadna konwersja nie jest
wykonywana.

Rozdziały
Chapters are converted to a XML format. This format is the same that mkvmerge(1)
supports for reading chapters. Alternatively a stripped-down version can be output in
the simple OGM style format.

Kody czasowe
Timestamps are first sorted and then output as a timestamp v2 format compliant file
ready to be fed to mkvmerge(1). The extraction to other formats (v1, v3 and v4) is not
supported.

KODY ZAMKNIĘCIA

       mkvextract(1) exits with one of three exit codes:

       •   0 -- Ten kod zamknięcia oznacza, że wyodrębnianie zostało zakończone powodzeniem.

       •   1 -- In this case mkvextract(1) has output at least one warning, but extraction 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.  mkvextract(1) aborts right after
           outputting the error message. Error messages range from wrong command line arguments
           over read/write errors to broken files.

ZMIENNE ŚRODOWISKOWE

       mkvextract(1) uses the default variables that determine the system's locale (e.g.  LANG
       and the LC_* family). Additional variables:

       MKVEXTRACT_DEBUG, MKVTOOLNIX_DEBUG i jego skrócona forma MTX_DEBUG
           The content is treated as if it had been passed via the --debug option.

       MKVEXTRACT_ENGAGE, MKVTOOLNIX_ENGAGE i jego skrócona forma MTX_ENGAGE
           The content is treated as if it had been passed via the --engage option.
