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.
