--- Comment #54 from Nicolas Dufresne (stormer) <nicolas.dufresne at collabora.co.uk> ---
In fact, memory:VASurface is used to state that stream will only hold buffer
witch contains memory of type VASurface. There could be no VASurface. So if you
had memory:DMABuf, that would mean memory travelling over this stream must be
GstBuffer backed by memory of type memory:DMABuf. Most use case for this is for
guaranties, or because it is known in advance that these DMABuf are not
mappable, so passing those DMABuf as if they where SystemMemory would fail the
requirement that a memory of type SystemMemory should be mappable to user
space. memory:SystemMemory (the default) can be a DMABuf of course, this is and
will always be a legitimate use case.
