|
|
Elements are required to make use of #GstContext to share and propogate
|
|
a #GstGLDisplay.
|
|
|
|
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', '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\().</doc>

If @respecify is %TRUE, then the copy is performed in terms of the texture
