Member Function Documentation

◆ createPlatformCamera()

void QGStreamerVideoSourcePrivate::createPlatformCamera ( QGStreamerVideoSource * source,
GstElementOrDescription elementOrDesc,
bool active = false )

\qmltype GStreamerVideoSource \nativetype QGStreamerVideoSource \inqmlmodule QtMultimedia

A video source backed by a custom GStreamer bin.

Construct the video source from a GStreamer bin description and attach it to CaptureSession using its \l{CaptureSession::}{nativeVideoSource} property.

For any standard case, we recommend using \l Camera instead of this type, unless you need GStreamer-specific configuration to handle any custom video source.

By default, the type is available only in meta-qt6 builds. In custom builds with GStreamer support, the gstreamer_qt_api feature can enable it.

QtMultimedia must be run with the gstreamer media backend for this class to work.

\qml Item { CaptureSession { nativeVideoSource: GStreamerVideoSource { gstElementDescription: "videotestsrc name=testsrc" active: true } videoOutput: preview }

VideoOutput { id: preview } } \endqml
