Command line usage
Invoking
Avidemux may be called with many arguments. The most obvious is avidemux(nbsp)myFile.avi, that will load myFile.avi.
You can also provide other commands, each one of them beginning by “–” to invoke an action. You won't have the full capabilities of the GUI though.
Warning: When in command line mode, all alert boxes will be skipped and questions will be automatically set to NO.
The arguments are evaluated from left to right and processed one at a time. The command line is far from bullet proof as most of the checks are inside the GUI.
A project file is a file containing all settings and loaded files. It is a “snapshot” of avidemux state at the point it was saved.
Commands
To get up to date command list and parameters, just invoke Avidemux with the argument --help.
