GI.Gst.Structs.ParentBufferMeta
Description
The GstMeta which can be attached to a #GstBuffer to hold a reference to another buffer that is only released when the child #GstBuffer is released.
Typically, #GstParentBufferMeta is used when the child buffer is directly using the #GstMemory of the parent buffer, and wants to prevent the parent buffer from being returned to a buffer pool until the #GstMemory is available for re-use.
