libdc1394 error: Failed to initialize libdc1394‏

Asked by hxu on 2010-01-13

Hello,
I tried to use a firewire camera on my desktop but failed.

Here is what I use:
*Debian lenny 2.6.26-1-686
*libraw1394-2.0.5
*libdc1394-2.1.2

Here are the results when I use the following commands.
@ lsmod |grep video1394
video1394 13372 0
ohci1394 24944 1 video1394
ieee1394 75800 3 raw1394,video1394,ohci1394

 @ls -al /dev/raw1394
crw-rw-rw- 1 root root 171, 0 2009-12-28 14:44 /dev/raw1394

@ ls -al /dev/video1394

The libraw1394 works well. The PCI card can be recognized when run the testlibraw under libraw1394/tools.

But when I run dc1394_reset_bus under libdc1394/examples, error message shows
"libdc1394 error: Failed to initialize libdc1394".

Does anyone have any idea about how to fix this problem? Thanks a lot.

Will check if the reset bus uses correctly the libraw...

What is the brand/model of your camera? Maybe it is not IIDC compatible...

Peter Antoniac (pan1nx) said : #2

I wonder if that reset bus uses the juju or legacy call. There was a discussion back couple of months on the same topic...

hxu (xuhuij) said : #3

The camera I used is Point Gray Flea2.

Peter Antoniac (pan1nx) said : #4

That error can only come from control.c and it is coming from dc1394_new call. It has nothing to do with reset bus. The only way that it could fail is via the legacy calls (basically, it doesn't load even the platform structure). Can you also export DC1394_DEBUG=1 and give us the output.

Can you help with this problem?
