GstUdmabufAllocator

This is a subclass of GstDmaBufAllocator that implements the gst_allocator_alloc method using memfd_create() and UDMABUF_CREATE. Platforms not supporting that (most non-Linux) will always return NULL.

Functions

gst_udmabuf_allocator_get 

GstAllocator*
gst_udmabuf_allocator_get ()

Get the GstUdmabufAllocator singleton if available.

Returns ( [transfer: full][nullable]) –

a GstAllocator or NULL if gst_udmabuf_allocator_init_once did not register the allocator.

Since : 1.28

GstAllocators.UdmabufAllocator.prototype.get 

function GstAllocators.UdmabufAllocator.prototype.get(): {
    // javascript wrapper for 'gst_udmabuf_allocator_get'
}

Get the GstAllocators.UdmabufAllocator singleton if available.

Returns (Gst.Allocator) –

a GstAllocator or null if GstAllocators.UdmabufAllocator.prototype.init_once did not register the allocator.

Since : 1.28

GstAllocators.UdmabufAllocator.get 

def GstAllocators.UdmabufAllocator.get ():
    #python wrapper for 'gst_udmabuf_allocator_get'

Get the GstAllocators.UdmabufAllocator singleton if available.

Returns (Gst.Allocator) –

a GstAllocator or None if GstAllocators.UdmabufAllocator.init_once did not register the allocator.

Since : 1.28

gst_udmabuf_allocator_init_once 

gst_udmabuf_allocator_init_once ()

Register a GstUdmabufAllocator using gst_allocator_register with the name GST_ALLOCATOR_UDMABUF. This is no-op after the first call.

Since : 1.28

GstAllocators.UdmabufAllocator.prototype.init_once 

function GstAllocators.UdmabufAllocator.prototype.init_once(): {
    // javascript wrapper for 'gst_udmabuf_allocator_init_once'
}

Register a GstAllocators.UdmabufAllocator using gst_allocator_register with the name GstAllocators.ALLOCATOR_UDMABUF. This is no-op after the first call.

Since : 1.28

GstAllocators.UdmabufAllocator.init_once 

def GstAllocators.UdmabufAllocator.init_once ():
    #python wrapper for 'gst_udmabuf_allocator_init_once'

Register a GstAllocators.UdmabufAllocator using gst_allocator_register with the name GstAllocators.ALLOCATOR_UDMABUF. This is no-op after the first call.

Since : 1.28
