That's not a correct statement. Whenever a format is becoming useful,
one will add it to GstVideo. We use fixed enumeration for performance
in caps negotiation. It's based on the premise that there is few new
formats every year. For truly opaque format, or formats that aren't
meant to be displayed, you can of course use your own mime-style
format, caps are generic in this matter (e.g. video/x-raw-opaque,...).
