Ok, I've tested it, but had to run pgrab as root, otherwise I get this error:

....
....
avccontroller.cc:75 INFO: AVCController::AVCController()
avccontroller.cc:84 WARNING: couldn't get raw1394 handle
avstream.cc:63 INFO:  _deliveredFrames=0
caught std exception: raw1394 system error
[booker at linux piave]$


But maybe this is a general problem on my machine, because I had to run kino also as root to be able to grab using the IEEE1394 interface.


So when running pgrab as root everything seems to work fine, but there is no captured file in the directory I've specified (please look shell output below).

Did I missed something?

Ooohhh, right now, as I copied the output below, I took notice of this line:

avstream.cc:69 INFO:  _recievedFrames=0

Is this the answer to my problem?

greetings
Reinhard
