Re: [PD] Linux, video1394 support?

2010-05-12 Thread Michal Seta
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 ;)

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

 Thanks

[PD] Linux, video1394 support?

2010-05-11 Thread Michal Seta
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 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.
