2.6.10 Avidemux Scripting: Introduction
Avidemux uses the QtScript scripting engine to provide scripting support for the ECMAScript language. This allows users to execute scripts that query and control the Avidemux environment. Scripts can either be written by the user or generated by Avidemux. The QtScript Debugger allows users to inspect the state of the script environment and control script execution.
