I have done in the past and so it is not that new a territory. However, this appears to be a continuing fiasco, unless I am doing something wrong. In this day and age, I should have not roll a new kernel for this kind of a problem. I mean, who in their right mind would think "Ah! Forget the firewire problem, people can compile their own kernel."? Also, you seem to imply that I should roll my own kernel and include the older firewire stack. I would rather I see why the newer one is not working. It is supposed to work, right? If not, then it beats the purpose! It appears to have matured quite a bit that the devs thought of discarding the older one from the compiled kernels. I have verified the same camcorder and the same cable on a Macbook Pro and the camera is detected properly and the video is grabbed without any problems; so the hardware is working properly. I have also tried the same cable and camcorder on different machine running Debian Linux, no luck. Debian appears to be broken in this respect. But it was not so in the past. Kino used to work, dvgrab used to work. In fact, dvgrab has saved me trouble time and again, it was that robust. I have never had this much trouble to get firewire working ... and it is not over yet! So, let me pose this question a bit differently. In today's Debian Testing, is there anyone here who has successfully grabbed dv video from a MiniDV camcorder at all using the newer firewire stack? And on a related note, is there anyone here who had trouble and was able to recompile the current Debian kernel to get this setup working? -- Please reply to this list only.

I have had some trouble with it (dvgrab refusing to find the camera), but I blamed that on the camera. Unplugging and re-plugging in the firewire cable tended to do the trick. There was a point when I couldn't get dvgrab to work, but it worked every time when I ran it under strace, so there could be timing issues. Unfortunately, I can only give these anecdotes and can't really help you, the DV camera was stolen last week and I don't think I'll get another one.

Well, that doesn't sound very encouraging. > There was a point when I couldn't get dvgrab to work, but it worked > every time when I ran it under strace, so there could be timing issues. No luck here with this either. > Unfortunately, I can only give these anecdotes and can't really help > you, the DV camera was stolen last week and I don't think I'll get > another one. Sorry about that. What a shame. This 'problem' has been around for at least 1.5 years, as far as I can remember. I couldn't even find a list of hardware that the newer stack explicitly does not work on. -- Please reply to this list only. I read this list on its corresponding newsgroup on gmane.org.
