Gutsy: KDEnlive cannot capture from FireWire

I get this too. Kino captures ok and can control my Sony DCR-HC36 no problem (when started by "sudo kino") but I read that KDEnlive was a better program.
When I first installed and ran KDEnlive the capture panel said I needed dvgrab which I got from synaptic, but then after the re-checking process, any of the capture buttons produce the error.

I concur with both reports; Kino can capture from my Sony DV-cam, kdenlive returns the error as described above.

Same problem here.

Kino can capture only after chmod /dev/raw1394 (not a funny action for regular users, designers and video editors).

I got dvgrab and ffmpeg with "sudo aptitude install", and when trying to capture with kdenlive, I get the same error.

I have the same problem. Completely fresh Gutsy install, only dvgrab, ffmpeg and kdenlive installed on top of default.

Behavior is exactly as described above.

Firewire is PCI card.
Camera is Sony Handycam DVR-HC42, attached to docking station.

Would love to get this resolved as kdenlive is far above the other existing Linux video editing packages, and using dvgrab from the commandline is a pain.

dvgrab 3.0 will not work with kdenlive. Get dvgrab 3.1 source from kino.org and install it.

Beyond that, you may need to update your permissions to /dev/raw1394 so you get read/write to it. Working for me now.

I can confirm the solution provided by Cactuswhack of 2007-12-15; installing dvgrab 3.1 will solve this issue.

Thanks Cactuswhack for your help !

I can also connfirm. After i get permission to /dev/raw1394, Kdenlive display:

Too many output file names.
Usage: dvgrab [options] [file] [-]
Try dvgrab --help for more information
pipe:: I/O error occured
Usually that means that input file is truncated and/or corrupted.

I confirm the problem (incompatibility between kdenlive and dvgrab 3.0) and the solution (uninstall dvgrab 3.0, download and install dvgrab 3.1 source). Please note that at this moment dvgrab 3.0 is also in Hardy.

"Too many output file names.

Yap I confirm too. uninstall dvgrab 3.0 and replace it with dvgrab 3.1 from kino website will solve the problems above.

I can confirm the issue.
With dvgrab 3.1 it works. Additionally I had to give right for /dev/raw1394 (chmod 666).

Please upgrade dvgrab to v3.1..
If Hardy will be an LTS release, it has to "Just work", isn't it?
But KDEnlive "Just doesn't work" with dvgrab v3.0.
Maybe v3.0 is more stable, but useless :-/

There won't likely be any upgrades -- KDEnlive in Hardy is SVN from
2007 December and they've turned that upgrade request down as well:

I'm not sure how we're supposed to consider this useful at all, having
a LTS with non-working, out of date apps and libraries.

Maybe we can ask the Medibuntu team to help us out on this?
