[libdc1394-devel] "Invalid video format" with Videre Design

[Matthias B. <mat...@gm...>]

Hi all,

has anyone tried to use the "Videre Design STH-MDCS2-var-C" camera(s)
with the new libdc1394 version? (IIDC spec 1.30, using Linux 2.6.15-27)

I am able to use it with the old libdc1394 and coriander-v1.0.1
but it produces following error while starting coriander:

"Invalid format query"

But after selecting a format from the (correct) drop down list in
coriander, the error does not occur anymore even if I reload the
raw1394-module. Only after reconnection of the camera the error happens
again (until manual reselect).
Because of this and the fact that it happens with both of my camera
modules (stereo vision) I think it's a problem of the hardware.

It was possible to ignore/workaround the above error in the old
libdc1394 version but in the new one it isn't anymore.
(I tried libdc1394-2.0.0-rc3 and current subversion.)
Even the helloworld example fails:

Libdc1394 error (control.c:dc1394_update_camera_info:369): Invalid video
format : Could not get current video mode
Libdc1394 error (helloworld.c:main:34): No camera : No camera on the bus

I suppose that this error indicates the same problem, I have with the
old version.
Another camera works fine with both versions of libdc1394 and coriander.

If I'm not sure but if I am NOT the only one having this problem,
perhaps we should create a workaround/fix for the new libdc1394 version?

Any questions? Need additional information of my system? Just ask.


Thanks for your help!

Regards,
Matthias
