Hi Kids!
Time for a new adventure. I would like to have a working firewire camera input for manipulation in Gem on a linux box that is sitting here purring at me. The cam works fine with Kino and dvgrab, so the linux-firewire connection is all well.
But I am having no luck with pix_video or pdp_v4l. The main problem seems to be that (apparently) recently the naming conventions in debian and possibly linux in general were changed. So there is no more /dev/video0 for the v4l mode, and for pix_video trying to work directly with ieee1394, I get complaints that /dev/ieee1394/dv/ host/PAL/in "Is a directory".
Has anyone had more luck? Do I need to going from stable to testing in some parts of debian? Do I need to use some special somethings?
Hi apparently this is a problem related to the new behavior of udev under Debian. I wouldn't recommand to downgrad udev though. I read the following on videolan's website:
if you have a distribution that uses udev, then you must add/change the following line to the file 50-udev.rules in your /etc/udev/rules.d directory.
%vi /etc/udev/rules.d/50-udev.rules # IEEE1394 (firewire) devices (must be before raw devices below) KERNEL=="raw1394", NAME="%k" KERNEL=="dv1394", NAME="dv1394/%k" KERNEL=="video1394*", NAME="video1394/%n"
I havent tested it yet, since i havent any DV cam before hand at the moment.
The workaround i used at the time is the following:
first check that you belong to the right groups : disk and video by issuing the command groups
If not, then
$ sudo adduser username disk $ sudo adduser username video
then run the attached bash script as a superuser after each restart:
$ sudo bash ./dv.sh
you might have to chmod +x the shell script
Start Pd/Gem, pix_video should work as expected if feeded with the pathname given in the shell script (I cant remember well this part, i'm sorry i'm only sending a translation of my blog notes, i dont have access to the original machine and Pd program this week (public holiday).)
The shell was adapted from an article about Ubuntu Edgy and DV cams
