Hi,
I can only capture 8-10 fps regardless of image
size using the bttv drivers and the v4l interface.
The type of card I have is an Osprey 100. The device
driver does not support read captures, so I have to
use mmap. Here is the gist of my code:
fd = open(/dev/video0, O_RDONLY);
video_pic
This is a simple question. I am trying to accurately see
how many frames i can grab and write per second using the
v4l interface on my slow mule box.
If my understanding is correct, with mmap, VIDIOCSYNC, frees
a specified frame and then the driver fills the mapped memory
with a video image.
anyone know about this card?
is there any known support for it?
here is the product link:

what cards are there that give a good picture at 640x480? I have
both the winnov PCI and the Opsrey 100, and I cannot capture at more
than 352x288 with them under linux.
