based approach simply because the limiting factor is the pixel resolution
along the 360-degree rotation path. The doughnut shaped image is limited
to a single frame of the video, and that's a pretty fierce limitation
when you remember that the image has to be unwrapped and stretched to
the full "width."
But for a "window" in a VR tour, I think it could be useful. The ability
to pan around a moving picture is quite fascinating--if people viewing
it can be encouraged to discover this function (which I doubt).
I am not familiar with the other video players you mention. Do they
provide a 360-degree field of view that you can pan around as the
video plays? That seems to be the whole (or main) point of this work.

mirror) could profit from being used with a really good camera that
combines the latest dynamic range coverage with high resolution images.
But I note that even the D300S doesn't take videos at its highest
native resolution. Video cameras with HD resolution are quite inexpensive
here in Japan, but HD stretched around a 360-degree wide image is not
really good enough for anything but a VERY small window. And of course
the doughnut image is circular, so it only takes advantage of the "narrow"
side of the rectangular HD image. Lots of wasted pixels, as we have
with circular fisheye images.
The alternative is to use multiple cameras, but then you have the
problems of synch and "stitching" the various images. Cost, too, of
course, which tends to drive things back towards cruder, cheaper cameras.

maintained in top condition. I have corresponded with the guy in
charge asking questions about their mirror-based approach, as I can
think of possible saleable applications where stitching is uneconomic
and acceptable quality much lower.

This could benefit from a frame-rate control. The quality is fine
but I find the speed multiplication caused by the present frame rate
quite unsettling. The movement of the clouds across the sky is
really nice to watch, and near real-time frame rates would enable
a less frenetic viewing experience.
