class GstGL.GLQuery

A GstGL.GLQuery represents and holds an OpenGL query object. Various types of queries can be run or counters retrieved.

New in version 1.10.

classmethod local_gl_context(element, direction, context_ptr)

Parameters:

• element (Gst.Element) – a Gst.Element to query from

• direction (Gst.PadDirection) – the Gst.PadDirection to query

• context_ptr (GstGL.GLContext) – location containing the current and/or resulting GstGL.GLContext

Returns:

whether context_ptr contains a GstGL.GLContext

context_ptr:

location containing the current and/or resulting GstGL.GLContext

Return type:

(bool, context_ptr: GstGL.GLContext)
