Summary0001751: Command line option for Playback upon opening file

Command line options don't offer a /play or similar option to open and starting playback (hence using OpenMPT for playback).

This is useful when setting OpenMPT as external viewer for module files in orthodox file managers like Total Commander or Far Manager.

Also, a /windowmode=normal|minimized|maximized option would complement the /play option.

For the time being, you could make use of openmpt123 included in, which seems more suited for the external player's role. Granted, it doesn't support some features, but it's much lighter and is still very powerful.

As of r20522, there is now a /play command line switch. Test builds can be obtained from

If multiple modules are passed, the last opened module will be played. This also works in conjunction with the /shared switch to reuse an existing OpenMPT instance.

Regarding the /windowmode flag, do you have any example of other software that supports this kind of switch? If Total Commander cannot passes the correct STARTUPINFO flags to OpenMPT, maybe you could detour the execution through the built-in Windows command start, which has /min and /max parameters, e.g. start /min path\to\openmpt.exe /play ...
