MapInfo
===================================================================

.. currentmodule:: gi.repository.Gst





.. class:: MapInfo(*args, **kwargs)
   :no-contents-entry:






A structure containing the result of a map operation such as
:func:`~gi.repository.Gst.Memory.map`. It contains the data and size.

:obj:`~gi.repository.Gst.MapInfo` cannot be used with g_auto() because it is ambiguous whether it
needs to be unmapped using :func:`~gi.repository.Gst.Buffer.unmap` or :func:`~gi.repository.Gst.Memory.unmap`. Instead,
``GstBufferMapInfo`` and ``GstMemoryMapInfo`` can be used in that case.
