GObject ╰── GInitiallyUnowned ╰── GstObject ╰── GstElement ╰── GstBaseTransform ╰── GstGLBaseFilter ╰── GstGLFilter ╰── GstGLViewConvertElement
Convert stereoscopic video between different representations using fragment shaders.
The element can use either property settings or caps negotiation to choose the input and output formats to process.
