## 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.

| --ui-language <code>

| Forces the translations for the language code to be used (e.g. de_DE for the German translations). If is preferable to use the environment variables LANG, LC_MESSAGES and LC_ALL though. Entering "list" as the code will cause mkvinfo to output a list of available translations.

| -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. If the summary mode is enabled then mkvinfo will output the frame position as well.

| 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.
