Memory.isSpan
bool isSpan(gst.memory.Memory mem2, out size_t offset)Check if mem1 and mem2 share the memory with a common parent memory object and that the memory is contiguous.
If this is the case, the memory of mem1 and mem2 can be merged efficiently by performing [gst.memory.Memory.share] on the parent object from the returned offset.
Parameters
mem2 | a #GstMemory |
offset | a pointer to a result offset |
Returns
true if the memory is contiguous and of a common parent.
