However, not what I'm trying to do. It's more like I'm trying to capture a VGA image every 5 or ten seconds, and then, say, save it or display it on one other machine. I do, in fact, work with vehicles, but generally maritime ones with old radars or depth sounding equipment.
Not many VGA framegrabbers exist even for PCI bus (which I'm trying to avoid, as I don't want a whole 'nother computer for this). We've used this in the past (hey! linux drivers!).
I've found the comments about streaming and getting around DRM interesting.
Basically, I'm talking about capturing a frame, oh, every 5 seconds. Really, there are alot of legacy systems I've been working with that have no output other than video! There's no way to record what's on the computer/embedded device other than grab the VGA output. This means a whole 'nother computer (and desktop grade at that) just for taking data. The webcam pointed at the screen is something that we have, in fact, tried. That kinda stuff doesn't work on the factory floor, nor does having another computer.
And believe me, there's work to be done using this kinda data aquisition in maritime applications.

Yep-- it's not like we ever outsource coding in the USA...
Yeah yah. Whatever...
I think John Stewart has used this rhetorical method enough. Please do not encourage it.
