Introduction

This is a filter wrapping the functionality of QJSEngine from the Qt framework.
Providing a simple way to use JavaScript code as filter in a filter graph, receiving and sending samples.

Note

The difference to the Qt5 QML Processor is that this filter is designed to work headless and synchronously in the trigger pipe.
Its triggers are handled by the GUI Thread, meaning that they are asynchron.

JavaScript Filter SDK

The following global javascript Objects are available in your scripts:

• adtf::javascript::scripting::cScriptFilter
• adtf::javascript::scripting::cScriptTypes
• adtf::javascript::scripting::cScriptClock

For all other available wrapper classes and objects please see adtf::javascript::scripting.
