Hello,
I have been trying to get a Point Grey Firefly (firewire) camera working in Linux (Karmic). It works fine with ReactiVision and coriander (the only 2 apps I tried). In pd, I was preferring [pix_video] but neither v4l2 driver nor dv1394 works (I believe this is a dc camera).
Does anyone have any experience with this camera in linux? Does anyone know of any OpenCV frontend that could deal with this kind of camera from where I could send OSC or something like that?
I need to get it working within a week :)
Thank you in advance for any leads!

[pix_video] has no support for IIDC cameras yet. it's planned for the next release, however.
the "dv" backend in pix_video refers to camcorder's (those ieee1394 cameras that don't work with coriander); it doesn't work with the new juju stack, however (found in recent linux kernels; most distributions seem to only ship this new stack :-()

if it is working with coriander, you should be able to pipe the data from coriander into Gem, using a vloopback device. make sure that you specify the proper dimensions on both sides manually.

AFAIK the RT kernel still has the old stack

so [pdp_ieee1394] isn't working? From there you could use [pix_2gem]

afaik, [pdp_ieee1394] is a pdp-clone of the videoDV backend of Gem; everything that applies to Gem's "dv" support should also apply to [pdp_ieee1394].
my information might be outdated, though.

pdp_ieee1394 was originally for OSX and is not in all pd-extended(s) for linux

I just used it on ubuntu Karmic with extended 41.4. Worked great.

Thanks for the tip. I will try it tonight.

So, nope, no go for me. [pdp_ieee1394] fails with initializing: Inappropriate ioctl for device
It is the same message I get with [pix_video]
Any other leads?

afaik, the current kernel (as in kernel.org) still has both stacks. however, most distributions enable only the new stack by default. i'm not sure what you mean by "the RT kernel"; is it a self-compiled kernel with some RT-patches applied? or do you mean a pre-compiled kernel from some to-be-specified distribution with a to-be-specified version?

Oh yes, I mean the RT kernel for Ubuntu - missing in Jaunty, present in Karmic and hopefully Lucid. This thread may be interesting: http://www.ffado.org/?q=node/1316

I did that but performance is rather unacceptable. I guess I will go that route if everything else fails.

Just for the record. The performance is not that bad, I made a mistake, something else in the pd patch was consuming lots of cycles.
Coriander tends to be CPU hungry and apparently I need to have display window open in order for it to schlep data over loopback. Displaying only a few frames a second in coriander cuts down on the CPU usage, while the number of frames can be set independently for the loopback.
Voilà. I do hope that this is only a temporary solution ;)
