Abstract:

No

Structure:

GstAllocators.UdmabufAllocatorClass

This is a subclass of GstAllocators.DmaBufAllocator that implements the Gst.Allocator.alloc() method using memfd_create() and UDMABUF_CREATE. Platforms not supporting that (most non-Linux) will always return None.

New in version 1.28.

classmethod get()

Returns:

a Gst.Allocator or None if GstAllocators.UdmabufAllocator.init_once() did not register the allocator.

Return type:

Gst.Allocator or None

Get the GstAllocators.UdmabufAllocator singleton if available.

New in version 1.28.

classmethod init_once()

Register a GstAllocators.UdmabufAllocator using Gst.Allocator.register() with the name GstAllocators.ALLOCATOR_UDMABUF. This is no-op after the first call.

New in version 1.28.
