> 8. Realize you need to modprobe raw1394 module into your running kernel. This could be a problem with Ubuntu's udev setup, or it could be a problem at the kernel level or hardware level. Whenever a DV/ miniDV/ HDV camcorder is plugged in and is recognized as such by the ieee1394 base driver (which needs the ohci1394 underneath), ieee1394 emits a hotplug event which should cause raw1394 be loaded automatically. raw1394's insertion should cause udev to create the /dev/raw1394 file, and at least that latter part apparently works for you. > 9.

Most other distributions which provide the raw1394 driver grant every user in a "video" group or something like that access to /dev/raw1394. This is because of security concerns of the Ubuntu maintainers; see bug 6290. However, there is light at the end of the tunnel since we are getting new firewire drivers into shape which will allow distributors to implement finer grained access policies. The new drivers don't use a single device file for all devices but a file for each FireWire node (e.g. one for the controller, one for a plugged-in camera...). There appear to be Jaunty test kernel packages which have the new drivers enabled in parallel to the old ones for advanced users to try them. See also bug 276463 (driver migration) and bug 311804 (libraw1394 migration; libraw1394 v2 is required to freely switch between old drivers and new drivers, libraw1394 v2.0.1 enables fine-grained access permission policy). > a.

So there are problems during FireWire I/O or related to disk I/O. There is DMA enabled for the harddisk, right? (hdparm -i /dev/... lists available and currently active DMA modes. It is highly likely that the kernel did enable DMA properly.) > b. You'll still get a "No camera found" error, which truely I'm in the > dark as to why.

It could presumably also happen with other camcorders though; it's just that we only discovered the nature of the problem and its solution very recently. > What I expected to happen, since things should 'just work', is that once > I plug in a camcorder to the 1394 jack, I'll get a popup window asking > me if I want to capture video from the device. Yes, that would be good to have. Would have to be implemented in Gnome and/or KDE. I don't know, maybe there is already integration of this sort between kernel -- KDE 4-- kdenlive. (kdenlive is in active development, while kino is retired to low maintenance mode.) > I also expect that a simple user, using the computer, wont need to > meddle with privileges, in order to get the actual device working for > them, That's, as mentioned, mostly a Ubuntu-specific problem, to be fixed in the short term by the user himself and in the long term by switching to the new drivers with more flexible permissions policy. Ironically, the new drivers are sponsored by Red Hat.

DV capture does actually work out-of-the-box for quite a lot of people, besides the missing pop-up dialogue when a camera was plugged in, and besides Ubuntu's bug 6290. -- raw1394 DV sampling should work out-of-the-box https://bugs.launchpad.net/bugs/300239 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
