NAME¶
mkvinfo - Print information about elements in Matroska(TM) filesSYNOPSIS¶
mkvinfo
[options] {source-filename}
DESCRIPTION¶
This program lists all elements contained in a Matroska(TM). The output can be limited to a list of tracks in the file including information about the codecs used. -g, --guiStart the GUI. This option is only available
if mkvinfo was compiled with GUI support.
-c, --checksums
Calculates and display the Adler32
checksum for each frame. Useful for debugging only.
-s, --summary
Only show a terse summary of what
mkvinfo(1) finds and not each element.
-t, --track-info
Show statistics for each track in verbose
mode. Also sets verbosity to 1 if it was at level 0 before.
-x, --hexdump
Show the first 16 bytes of each frame as a hex
dump.
-X, --full-hexdump
Show all bytes of each frame as a hex
dump.
-z, --size
Show the size of each element including its
header.
--command-line-charset character-set
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 character-set
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 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
Forces the translations for the language
code to be used (e.g. 'de_DE' for the German translations). It is
preferable to use the environment variables LANG, LC_MESSAGES
and LC_ALL though. Entering 'list' as the code will cause
mkvinfo(1) to output a list of available translations.
--debug topic
Turn on debugging for a specific feature. This
option is only useful for developers.
--engage feature
Turn on experimental features. A list of
available features can be requested with mkvinfo --engage list. These
features are not meant to be used in normal situations.
-v, --verbose
Be more verbose. See the section about
verbosity levels for a description which information will be output at which
level.
-h, --help
Show usage information and exit.
-V, --version
Show version information and exit.
--check-for-updates
Checks online for new releases by downloading
the URL http://mkvtoolnix-releases.bunkus.org/latest-release.xml. Four lines
will be output in key=value style: the URL from where the information was
retrieved (key version_check_url), the currently running version (key
running_version), the latest release's version (key available_version) and the
download URL (key download_url).
Afterwards the program exists with an exit code of 0 if no newer release is
available, with 1 if a newer release is available and with 2 if an error
occured (e.g. if the update information could not be retrieved).
This option is only available if the program was built with support for
libcurl.
@options-file
Reads additional command line arguments from
the file options-file. Lines whose first non-whitespace character is a
hash mark ('#') are treated as comments and ignored. White spaces at the start
and end of a line will be stripped. Each line must contain exactly one option.
Several chars can be escaped, e.g. if you need to start a non-comment line with
'#'. The rules are described in the section about escaping text.
The command line ' mkvinfo -v -v input.mkv --redirect-output info.txt'
could be converted into the following option file:
# Be more verbose -v -v # Parse input.mkv input.mkv # and write the output to info.txt --redirect-output info.txt
VERBOSITY LEVELS¶
The -v option can be used to increase mkvinfo(1)'s verbosity level and print more information about the current file. At level 0 mkvinfo(1) will print only the track headers it finds and their types. mkvinfo(1) will exit as soon as the headers are parsed completely (more technical: as soon as the first cluster is encountered). In this level the seek head entries and the cues will not be displayed -- even if they're located in front of the track information. At level 1 mkvinfo(1) will also print all Matroska(TM) elements encountered for the complete file but the seek head entries and the cue entries. If the summary mode is enabled then mkvinfo(1) will output the frame position as well. At level 2 mkvinfo(1) will also print the seek head entries, the cue entries and the file position at which each Matroska(TM) element can be found at. At level 3 and above mkvinfo(1) will print some information that is not directly connected to a Matroska(TM) element. All other elements only print stuff about the elements that were just found. Level 3 adds meta information to ease debugging (read: it's intended for developers only). All lines written by level 3 are enclosed in square brackets to make filtering them out easy.EXIT CODES¶
•
0 -- This exit codes means that the run has completed successfully.
•
1 -- In this case mkvinfo(1) has output at least one warning, but
the run did continue. A warning is prefixed with the text 'Warning:'.
•
2 -- This exit code is used after an error occurred. mkvinfo(1)
aborts right after outputting the error message. Error messages range from
wrong command line arguments over read/write errors to broken files.
ESCAPING SPECIAL CHARS IN TEXT¶
There are a few places in which special characters in text must or should be escaped. The rules for escaping are simple: each character that needs escaping is replaced with a backslash followed by another character. The rules are: ' ' (a space) becomes '\s', '"' (double quotes) becomes '\2', ':' becomes '\c', '#' becomes '\h' and '\' (a single backslash) itself becomes '\\'.ENVIRONMENT VARIABLES¶
The content is treated as if it had been
passed via the --debug option.
MKVTOOLNIX_ENGAGE and its short form MTX_ENGAGE
The content is treated as if it had been
passed via the --engage option.
MKVTOOLNIX_OPTIONS and its short form MTX_OPTIONS
The content is split on white space. The
resulting partial strings are treated as if it had been passed as command line
options. If you need to pass special characters (e.g. spaces) then you have to
escape them (see the section about escaping special characters in text).
