Hi,

The GstSurfaceMeta is not really usable as is. I think it would be much simpler
to simply make gst_surface_meta_create_converter() take a GstBuffer instead of
a GstSurfaceMeta, unless it is possible to retrieve the parent GstBuffer from a
GstMeta. Likewise, GstSurfaceMeta::create_converter would also take a GstBuffer
argument. That way, we will have similar semantics to older 0.10
GstSurfaceBuffer.

No patch yet, as I am undecided on whether (i) I simply nuke GstSurfaceMeta arg
away and replace it with GstBuffer, or (ii) simply add GstBuffer after the
GstSurfaceMeta * argument. I would favor option (i) for now.

However, for OpenGL use cases, there is still the question how do we get the
original GL context? Would the client application or library actually allow
exposure of its internal GL context, from which the GL texture was created
from?
