## 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.

| inname |  | Use ’inname’ as the source. |

| -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.
