[ros-users] Digital Camera 1394 in ROS?

[Dejan Pangercic]

Dear all,

this is a slightly derailed topic, but I guess that some of ROS users
using FireWire cameras might be familiar with it.
In Ubuntu 9.04 (2.6.28.16 kernel) I tried getting images from my
Marlin FireWire camera using "camera1394" package which resulted in
the "firewire bus not initialized" error.

When I checked "dmesg" command I noticed that the kernel does not
really react to plugging/unplugging of the camera. I have necessary
ubuntu packages installed (libdc1394-22-dev, libdc1394-22,
libraw1394-8, libraw1394-dev) and the /dev/[raw | video]1394 files
with writing rights are there as well. Usual fallback to get images
with "coriander" software also failed.

I guess my questions would now be:
a)Has anyone else experienced the similar behaviour?
b)Is the system installation of libdc1394-22-dev and libdc1394-22
actually needed (given camera1394 pkg depends on libdc1394v2)?
c)According to https://ieee1394.wiki.kernel.org/index.php/Release_Notes#Linux_2.6.31,
the old FireWire drivers are slowly getting deprecated. How will this
affect/fit into the camera1394 pkg?


thx and cheers, D.
