mkvinfo(1): Print info about tracks in Matroska ...

NAME

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.

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.
