...the gluLookat() based camera can be imagined as a sphere surrounding a point, with the camera on the surface of the sphere always looking at the center...to go "forward", the sphere gets smaller, until you arrive at center point: then you automatically flip around and look back at the object...I guess what you are talking about is a way around this where the "lookat" point is constantly changing? That sounds like a lot of work, and I was hoping for a simpler, more generalized solution...
right, i was thinking of moving both the camera-point and the target-point. (it's just a bit of vector arithmetics;-))
so the error now is more like "pix object [pix_alpha] cannot handle YUV". but of course, still the user has no clue about what could be done on their side to fix this.
and while testing i have noticed that the [pix_alpha] did some very strange things with grayscale-images: converting RGB to RGBA inplace, which of course was urging for segfaults...
