GstGLBaseFilterGstGLBaseFilter — GstBaseTransform subclass for transformin OpenGL resources |
GObject ╰── GInitiallyUnowned ╰── GstObject ╰── GstElement ╰── GstBaseTransform ╰── GstGLBaseFilter ╰── GstGLFilter
GstGLBaseFilter handles the nitty gritty details of retrieving an OpenGL
context. It also provided some wrappers around GstBaseTransform's
start(), stop() and set_caps() virtual methods that ensure an OpenGL context
is available and current in the calling thread.
