Starting up firewire for camcorder [solved]

[Unclethommy]

Hi i've enable the firewire options in my kernel and asked it to be loaded into the kernel rather than modules. Having booted it says that raw1394 is loaded. However when i start kino (whether as root or as normal user) is say that the raw1394 module is not loaded. I've checked using dmesg:

heaven mark # dmesg | grep 1394
ieee1394: raw1394: /dev/raw1394 device initialized


Seems to have intialized. Does it need to be loaded as a module? I've installed dvgrab as some people say it solved the problem but i still cant connect to the camera.

Any ideas would be greatly appreicated.


Thanks

I'd try building it in as a module. In my experience, it seems often that there are issues (maybe udev's fault?) with drivers being built into the kernel for devices which are connected and disconnected. So, in general, I try to build all plugged-in devices as modules.

Also, you can do:

I've tried building the ieee1394 driver as a module and loaded using modprobe for both ieee1394 and raw1394 which have loaded up fine as seen below:

heaven mark # lsmod
Module Size Used by
raw1394 21620 0
ieee1394 74932 1 raw1394
spca5xx 649488 0
lirc_gpio 7984 0
lirc_dev 10852 1 lirc_gpio
ext3 92808 3
jbd 40724 1 ext3
nvidia 4543444 12 [permanent]


Using kino still gives me an error saying: "WARNING: raw1394 kernel module not loaded or failure to read/write /dev/raw1394!

Can anyone help? this is really the only problem which i havent managed to solve before i can finally drop using windows XP

I had the same problem today, but now it works
It seems that the reason is ohci1394 module missing

[Unclethommy]

I've recompiled my kernel with ohci1394 enabled as a module, i'm one step closer as the warning from kino (0.9.0 with patch) doesnt display anymore and it displays my cameras name in the ieee1394 section under preferences. Problem is when i try to control the camera with the buttons it crashes giving the following output.I'm going to try and post the problem on the kino forum but I thought of adding it here too incase something looks familiar.

My lsmod is as follows (i think i have every possible 1394 module module installed) :


heaven mark # lsmod | grep 1394
video1394 14164 0
raw1394 21620 0
dv1394 14932 0

Did some digging on the internet and apparently the fault is due to the latest version of libdv-0.104-r1. the problem is resolved when it is rolled back to 0.104. Hope this helps others. Thanks for all the support. Much appreciated.

Unclethommy,
which version of gcc do you have?

I have the same problem with crashing of kino. Though I can capture movies from camera, but if I try to use controls - kino crashes. More of this, it crashes when I try to open captured video files for editing. However it is possible to play them with mplayer, so they should be ok.

I have 4.1.1(-r1) and cannot compile libdv-0.104 (see https://forums.gentoo.org//viewtopic-t-494961.html, for instance)
So for now I do not see what should I do (downgrade gcc? )

[Unclethommy]

I'm using 4.1.1 (not r1) so it may be the culprit. The problem was fixed when i downgraded libdv, works like a charm now (only niggle is the sound plays out of my camcorder when its playing films which can be irritating when you want to do other things, wasnt a problem in windows as the usb capture from the camcorder muted the camcorder's sound even though it copied it to the the hardrive with the video. I'm not a pro and so havent been able to try to establish a connection via USB. Does such software exist?)


EDIT: I just checked my camcorder for you and it definitely stops working when r1 version of libdv gets installed (emerge -update accidentally upgraded it) . On forcing it to downgrade. It works fine (still noisy )

Hope it helps. I know the frustration so i fell you pain lol.

[romamax]

So I did it. I have emerged gcc-3.4.6-r1 and successfuly compiled libdv-0.104. And now it works perfectly!

However I don't believe that exactly -r1 in my gcc-4.1.1 makes it not to compile libdv-0.104 (see the link in my previous post for problems with libdv-0.104 (and -0.102) and gcc-4.1.1; it is said there that libdv-0.104-r1 was the solution of the problem; and it was indeed the solution, but in the case of kino it made only problems... )
