Bindings for Qt

About

QtGStreamer provides C++ bindings for GStreamer with a Qt-style API, plus some helper classes for integrating GStreamer better in Qt applications.

Status

The QtGStreamer C++ bindings are very out of date and unmaintained.

For integration with the Qt toolkit there is the qmlgl plugin in gst-plugins-good which provides the following elements:

  • qmlglsink: a video sink that renders to a QQuickItem in a QML application
  • qmlglsrc: A video src that captures a window from a QML view
  • qmlgloverlay: afilter that renders a QML scene onto a video stream

Features

  • uses QtCore helper classes (QString, QList, etc..) where it can, to ease integration with Qt
  • provides proper Qt event loop integration for GstBus, which is useful for platforms where Qt is not compiled with GLib event loop support
  • provides a video widget for plugging several GStreamer video sinks into Qt GUI applications (outdated, see above)
  • provides support for connecting arbitrary GObject signals to C++ slots in a type safe manner, without knowing the signals interface at compile time. This is especially useful for connecting signals from element plugins
  • provides bindings that completely hide the GStreamer ABI, so your application doesn’t need to link to GStreamer itself
