everything seems to be working, expect video input.

cool

with message "enummerate" i got info: devices 1 info: device /dev/fw1 dv4l

which means that Gem found one device named "/dev/fw1", and it's using the dv4l backend.

but with "device 3" i got

why do you use "device 3"?

error: videoDC1394: no cameras found

this has several reasons: #1: enumerate told you that there is exactly 1 device; you requested device#3, which is obviously not there. #2: according to what enumerate told you, the 1 device it found is a DV4L device (that is: an ordinary "dv" device, rather than a IIDC device)

i ran puredata with root privileges

no need for that. just make sure that you have read/write perms on the devices you want to access. actually i would highly encourage you to _not_ run pd as root, and instead change the perms for /dev/fw1 so you can access it (for testing a quick "sudo chmod a+rw /dev/fw1" should be enough, but on the long run you should read the udev documentation and make sure that devices created for your camera are g+rw and belong to a group you are member of (e.g. "video"))

so the main obstacle you are facing seems to be how to tell Gem to open the correct device.

since "enumerate" tells you, that there is exactly one available device named "/dev/fw1", i would _strongly_ suggest that you try [device /dev/fw1(

given that this is the third time in this thread that i hint to you that the proper device name could be "/dev/fw1", i would suggest you try it :-)
