MKVINFO

NAME

mkvinfo − Print information about tracks in Matroska files

SYNOPSIS

mkvinfo [options] inname

DESCRIPTION

This program lists all tracks contained in a Matroska file including information about the codecs used.

−g, −−gui

Start the GUI. This option is only available if mkvinfo was compiled with GUI support.

−v, −−verbose

Be verbose and show all Matroska elements. See the section ´VERBOSITY LEVELS’ for details.

−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 finds and not each element.

−−output−charset <charset>

Sets the charset to which strings are converted that are to be output. It defaults to the charset given by system’s current locale.

-r, −−redirect−output <filename>

Writes all messages to the file filename 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 charset set with −−output-charset is honored.

−h, −−help

Show usage information.

−V, −−version

Show version information.

VERBOSITY LEVELS

The -v option can be used to increase mkvinfo’s verbosity level and print more information about the current file.
level 0

will print only the track headers it finds and their types. mkvinfo 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.

level 1

will also print all Matroska elements encountered for the complete file but the seek head entries and the cue entries.

level 2

will also print the seek head entries, the cue entries and the file position at which each Matroska element can be found at.

level 3

will print some information that is not directly connected to a Matroska 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.
