Description Palm Pre 2011-06-21 03:34:35 CEST
Description of problem: I'm trying to get video from miniDV recorder. The only message

$ dvgrab
Error: no camera exists

An old discussion (https://bbs.archlinux.org/viewtopic.php?id=38826) suggested to remove and install firewire-core and firewire-ohci modules. 

Just in case 
# lsmod | grep firewire
firewire_ohci          39903  0 
firewire_core          62218  1 firewire_ohci
crc_itu_t              12707  1 firewire_core

# lsmod | grep 1394

Sorry for responding so late.

Does it make any difference if you run dvgrab as root?

$ dvgrab -f raw 

does the job.

Thanks.

So it works :)

I can't find here http://www.kinodv.org/article/view/46/1/14/ 
nor here http://www.kinodv.org/article/view/46/1/14/
nor when reading the dvgrab man and info pages, what dvgrab should do when you don't give any options, but I could very well be overlooking something. 
And of course, if it can't do without an option, it shouldn't tell it didn't detect a camera but ask for the option instead.

What happens now when you do $ dvgrab ?

It used to be the same error

$ dvgrab
Error: no camera exists

I updated the system yesterday. 
Now

$ dvgrab
Found AV/C device with GUID 0x008088030a60e61a

I don't really think $ dvgrab should work when no options are given.

Not getting a message that you should give an option when you haven't given one, might be an upstream thing.

Anyway, it works for you now, the original bug report was that it didn't work.

I'm closing this bug. Feel free to reopen it if you don't agree
