Elise,

I wrote the original Mac OS support for libdc1394 several years ago but I did so using Firewire 400 devices. I suspect the problem here is that the support for Firewire 800 devices is incomplete.

If you're willing to venture into the libdc1394 backend code for Mac OS, you might be able zero-in on the issues fairly quickly. I would hope that only minor changes would be required to get Firewire 800 working.

Regards,
David

I've been using libdc on OSX (an imac)  for a while. But lately, I've been having problems with the newer AVT cameras.
AVT guppy pro and the newer Stingray.

I tried running the example code grab_gray_image with the Guppy pro.
got errors:
libdc1394 warning: Forcefully killing servicing task...
libdc1394 error: Not enough iso bandwidth or channels are available to begin capture
libdc1394 error: Generic failure: in main (grab_gray_image.c, line 128): Could not setup camera-
make sure that the video mode and framerate are
supported by your camera

Not too sure what to do  with that.

When running these two cameras with what I've been using for the last few years, I get these generic failures... What could cause that? Did something change in the AVT firmware?
