2. Description

mkvtoolnix-gui(1) is a Qt(tm) based GUI for mkvmerge(1). It also implements mkvinfo(1)'s and mkvpropedit(1)'s functionality and will evolve to cover mkvextract(1) 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.
