Can you please direct me to the three lines of code which will
allow me to do this?"
If the poster gets any response at all, it is something like,
"Please see Son Of Grandnephew of MungGrabHack. Several hundred lines
into this wad of code, you might find if you're lucky, a callback which,
if you do it right, might work. By the way, most example code is
deprecated."
This usually makes the poster disappear, probably off to DirectX or
Linux.
Not only is the code obscure (what does SGIdle() really do anyway?
how does
it interact with OpenGL?), but it is dog slow. A 120 MHz 8500 from more
than a decade ago had a video latency of two frames. In the intervening
years, processor speed has increased a factor of 20, yet the latency
is several
times longer. Part of this is due to the loss of ability to process
uncompressed video, but surely with multiple processors we can do
better.
Could we have a quick and simple pure video API? Audio is not required.
High resolution is not necessarily important. But latency is, both for
vision research and for video art/VJ applications.
Thank you for this ranting opportunity.
