## Synopsis

`mkvtoolnix-gui` configuration-file-name.mtxcfg source-file.ext --info matroska-file.mkv --edit-chapters chapter-file.ext --edit-headers matroska-file.mkv

## Description

&mkvtoolnix-gui; is a Qt based GUI for &mkvmerge;. It also implements &mkvinfo;'s and &mkvpropedit;'s functionality and will evolve to cover &mkvextract; as well. All settings (e.g. source files, track options etc) can be saved and restored.

Listing configuration file names with the extension `.mtxcfg` causes the GUI to load the those configuration files in the appropriate tool. Any other file name is added as a source file for multiplexing, opened in the info tool, the chapter editor or in the header editor depending on the current mode. The current mode can be changed with `--merge`, `--info`, `--edit-chapters` or `--edit-headers`. The default mode is adding files for multiplexing.

Note that if an instance of the application is already running when the application is started a second time, all file names given on the command line are handled by the already-running instance.

`--merge`

  All following file names will be added as source files to the current multiplex job. This is the default mode.

`--info`

  Additionally the info tool will be selected on startup instead of the multiplexer tool.
