Hey Jamie...
Not sure if this is really the answer you're looking for but anyway.....
If you do a..
struct video_capability videoCapability;
ioctl(_videoDevice, VIDIOCGCAP, &videoCapability)
and look at...
videoCapability.minwidth
videoCapability.minheight
videoCapability.maxwidth
videoCapability.maxheight
This will tell you the min/max capture sizes of the card... Based on that
info you know the info for a correct call to..
struct video_mmap videoMmap;
ioctl(_videoDevice, VIDIOCMCAPTURE, &videoMmap)
Hope this helps...
Cheers,
-Smity
