If the meta is on a buffer but not in the caps as capsfeatures, this means that
the memory can be used like normal system memory too. So there's indeed
something missing here if the buffer content describes a different format
depending on whether you use the meta or access it directly. Maybe needs
another field in the meta to set the format, but how could that then be
negotiated? We can't just add another field to the video/x-raw caps.


Independent of that, if you have multiple capsfeatures in a caps they are AND
combined. That is downstream must support *all* of the features. When
negotiating the elements need to decide on a set of features that is supported
by everything.
