Description simon 2007-05-02 11:45:22 UTC
Kino 1.0.0 has problems with capturing from my DVCam. Cam is a Canon MV930,
raw1394 is loaded, /dev/raw1394 exists and has correct permission, user is in group "video".

In fact, the cam is recognized by Kino (Edit > Prefs > ieee1394), but capturing does not work, nor do the control buttons work with the cam.

When I start Kino from the console, it gives me the following:

dvgrab does not work either:
simon@baruch ~ $ dvgrab --frames 25 Clip-
                                                                              ""     0.00 MB 0 frames
                                                                              Capture Stopped
Error: no DV

In the Gentoo-Forums, there is a hint that this might be due to a bug in libdv:

However, the solution found there - i.e., downgrading libdv - is not possible any more. I tried to upgrade libdv to the testing version - same result.

Reproducible: Always

Steps to Reproduce:
1.launch Kino
2.try to capture from dvcam connected to firewire-port

Actual Results:  
capturin not working

What is the output of "dmesg"
  - when the ohci1394 kernel module was loaded,
  - when the camera is plugged in/ switched on,
  - when Kino is trying to access the camera?
Comment 3 simon 2007-05-13 13:57:45 UTC
when loading module:
ieee1394: Initialized config rom entry `ip1394'
ohci1394: fw-host0: OHCI-1394 1.0 (PCI): IRQ=[40]  MMIO=[f5000000-f50007ff]  Max Packet=[2048]  IR/IT contexts=[4/4]
ohci1394: fw-host0: SelfID received outside of bus reset sequence
ieee1394: Host added: ID:BUS[0-00:1023]  GUID[000393fffe1a8e70]

when plugging in and switching on the cam:
ieee1394: The root node is not cycle master capable; selecting a new root node and resetting...
ieee1394: Node added: ID:BUS[0-00:1023]  GUID[00008500013a51de]
ieee1394: Node changed: 0-00:1023 -> 0-01:1023
ieee1394: raw1394: /dev/raw1394 device initialized

when trying to access the cam from Kino:
no change, neither when pressing the Capture-View tab nor when pressing the Capture button in the capture-window 
(note that the play/forward/rewind buttons in Kino's capture window are greyed out. Message in the status bar of Kino is "AV/C Controls Not Enabled") 

Perhaps I should also mention that this happens only on my G4 Powerbook Ti, on my i386-Desktop capturing works fine.
Comment 4 Stefan Richter 2007-05-13 14:40:27 UTC
The driver outputs look OK. Perhaps there is an endianess bug in a library or in Kino.  Maybe you should post your report at .
Comment 5 Denis Dupeyron (RETIRED) gentoo-dev 2007-05-19 15:07:51 UTC
Thanks Simon for reporting this, and Stefan for trying to help.

Simon, this looks definitely like it's an upstream issue. Could you please see with them to try and debug your issue ? Their mailing list is there :
The main author, Dan Dennedy, is usually quite helpful.

In the meantime I'm resolving this as UPSTREAM. Do not hesitate to reopen in case you end up finding out it is a Gentoo issue after all. But I'd be really surprised.

Comment 6 simon 2007-05-20 09:52:30 UTC
I reported the issue upstream right now.
Thanks everybody
