Detailed Description

The VideoOutput class A VideoRenderer wrapper with QObject features.

If create VideoOutput without a given renderer id, QtAV will try to create a widget based renderer, and dynamically load QtAVWidgets module if it's not loaded.

Constructor & Destructor Documentation

QtAV::VideoOutput::VideoOutput ( QObject * parent = 0 )

VideoOutput Create a QWidget based renderer.

Result can be a QOpenGLWidget or QGLWidget based renderer if possible. Otherwise fallback to a software renderer

QtAV::VideoOutput::VideoOutput	(	VideoRendererId	rendererId,
		QObject *	parent = `0`
	)

VideoOutput Create a renderer with given rendererId.

MUST check VideoOutput::isAvailable() later!
