That's what Alex suggest with his option number 3. E.g. write a new extension
that allows application to query if a subset of GL_NV_vdpau_interop is
supported.
But since this only applies to rather old hardware nobody is probably going to
do so.
Option number 2 is actually rather easily doable as well, cause we already have
most shaders for this available. Maybe fifty lines of code after all.
But again, rather old hardware and so nobody of the devs interested in fixing
this.
If you are interested in coding this I can easily give you the hints where to
look at.</pre>
