Details

class Gst.MapInfo

A structure containing the result of a map operation such as Gst.Memory.map(). It contains the data and size.

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

clear()

Release the memory obtained with Gst.Memory.map()

Return type:
