acquire_memory()

Returns:

a Gst.FlowReturn such as Gst.FlowReturn.FLUSHING when the allocator is inactive.

memory:

a Gst.Memory

Return type:

(Gst.FlowReturn, memory: Gst.Memory)

Acquires a Gst.Memory from self. memory should point to a memory location that can hold a pointer to the new Gst.Memory.
