[VDPAU] Fake VDPAU library

[José Hiram Soltren]

Hello Vincent,

I am the current maintainer of VDPAU.

I do not presently know of a fake VDPAU library as you describe, or a
VAAPI backend. Such a VDPAU library would take some effort to write as
it would need to be stateful and correctly implement the semantics of
VDPAU. For example, a call to VdpVideoSurfaceCreate() should require a
previous call to VdpDeviceCreateX11() to create a VdpDevice, just as it
does on any VDPAU implementation.

A fake VDPAU library would be helpful in the use case you mention.
Unfortunately, I am unable to commit to any release date or timeframe
for such a library at present.

The VDPAU API works with multiple implementations by design. If you or
anyone else implement such a library please do feel free to announce it
on this list.

Regards,
--José
