Memory.map

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.Memory.unmap is called.

For each gst.memory.Memory.map call, a corresponding gst.memory.Memory.unmap call should be done.
