Struct GLDisplay
Sourcepub struct GLDisplay { /* private fields */ }Expand description
GLDisplay represents a connection to the underlying windowing system.
Elements are required to make use of gst::Context to share and propagate
a GLDisplay.
There are a number of environment variables that influence the choice of platform and window system specific functionality.
- GST_GL_WINDOW influences the window system to use. Common values are ‘x11’, ‘wayland’, ‘surfaceless’, ‘win32’ or ‘cocoa’.
- GST_GL_PLATFORM influences the OpenGL platform to use. Common values are ‘egl’, ‘glx’, ‘wgl’ or ‘cgl’.
- GST_GL_API influences the OpenGL API requested by the OpenGL platform. Common values are ‘opengl’, ‘opengl3’ and ‘gles2’.
Certain window systems require a special function to be called to initialize threading support. As this GStreamer GL library does not preclude concurrent access to the windowing system, it is strongly advised that applications ensure that threading support has been initialized before any other toolkit/library functionality is accessed. Failure to do so could result in sudden application abortion during execution. The most notably example of such a function is X11’s XInitThreads().
§Signals
§create-context
Overrides the GLContext creation mechanism.
It can be called in any thread and it is emitted with
display’s object lock held.
Object
§deep-notify
The deep notify signal is used to be notified of property changes. It is typically attached to the toplevel bin to receive notifications from all the elements contained in that bin.

§Implements

fn watch_closure(&self, closure: &impl AsRef<Closure>)
Limits the lifetime of
closure to the lifetime of the object. When
the object’s reference count drops to zero, the closure will be
invalidated. An invalidated closure will ignore any calls to
invoke_with_values, or
invoke when using Rust closures.Source§fn emit<R>(&self, signal_id: SignalId, args: &[&dyn ToValue]) -> Rwhere
