first flag that can be used for custom purposes
the memory can't be mapped via gst_memory_map() without any preconditions. (Since: 1.2)
memory must not be shared. Copies will have to be made when this memory needs to be shared between buffers. (DEPRECATED: do not use in new code, instead you should create a custom GstAllocator for memory pooling instead of relying on the GstBuffer they were originally attached to.)
the memory is physically contiguous. (Since: 1.2)
memory is readonly. It is not allowed to map the memory with #GST_MAP_WRITE.
the memory padding is filled with 0 bytes
the memory prefix is filled with 0 bytes
