Fill @info with the pointer and sizes of the memory in @mem that can be
accessed according to @flags.
This function can return %FALSE for various reasons:
- the memory backed by @mem is not accessible with the given @flags.
- the memory was already mapped with a different mapping.
@info and its contents remain valid for as long as @mem is valid and
until gst_memory_unmap() is called.
For each gst_memory_map() call, a corresponding gst_memory_unmap() call
should be done.
