Re: [PD] Linux, video1394 support?
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 ;) ./MiS On Wed, May 12, 2010 at 12:59 AM, Michal Seta m...@artengine.ca wrote: On Tue, May 11, 2010 at 10:08 AM, IOhannes m zmoelnig zmoel...@iem.at wrote: you should be able to pipe the data from coriander into Gem, using a vloopback device.

[PD] Linux, video1394 support?
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! ./MiS ___ Pd-list@iem.at mailing list UNSUBSCRIBE and account-management - http://lists.puredata.info/listinfo/pd-list
