Since a few days we have the same camera (Sony DFW-VL500), but a =
different
host adapter card (Exsys 6500, ohci).

- kernel 2.2.17 (Suse 7.0)
- latest patch for ieee1394 module, libraw1394 (0.8.2) and libdc1394 =
(0.2)
(+ download of CVS sources)
- coriander 0.0.8 (very nice GUI for using libdc1394)
- samplegrab application from Chris Urmson=20

Be careful about the following when using samplegrab:=20
libdc1394 has been split up recently into a capture part and a control =
part
(and also .c files)! This change is not yet considered in samplegrab.c! =
You
have to replace the function call to dc1394_setup_camera with
dc1394_setup_capture !!!

With all this bleeding edge code we succeeded in capturing pictures =
from the
Sony camera. Interestingly we didn't succeed under Win2000/WinNT so far =
:-()

Now it would be nice to do that with DMA access (via video1394 rather =
than
raw1394), but there are no samples for using video1394 together with =
libdc
(coriander will do that in the future???)
