alloc

Description:

public static Memory? alloc (Allocator allocator, int fd, size_t size, FdMemoryFlags flags)

Return a gstmemory that wraps a generic file descriptor.

Parameters:

allocator	allocator to be used for this memory
fd	file descriptor
size	memory size
flags	extra FdMemoryFlags

Returns:

a GstMemory based on allocator. When the buffer will be released the allocator will close the fd unless the gst_fd_memory_flag_dont_close flag is specified. The memory is only mmapped on map request.
