hi all
i would lije to use a unibrain firewire camera for tracking in debian. my problem is that i can see the picture in coriander, but mot in pd/gem/pidip.
any ideas?
#1 (Gem only) upgrade to the latest and greatest Gem (svn!), where you can read iidc cameras directly
#2 older versions of Gem and pdp don't have iidc support; so you need to somehow make your camera's images show up in v4l(2) devices
#2a v4l1-loopback: coriander already comes with v4l1-loopback support; in order to use it you have to, install the the v4loopback kernel module: # module-assistant auto-install vloopback # modprobe vloopback this will give you 2 new devices e.g. /dev/video1 (being the "pipe" where coriander can write to) and /dev/video2 (being the "pipe" that pix_video/pdp_v4l can read)
#2b v4l2-loopback (which i favour as it is more modern and i have my fingers in it) if you are on debian/sid you can simply do: # modula-assistant auto-install v4l2loopback # modprobe v4l2loopback this will give you 1 new device e.g. /dev/video1 which can be written to by e.g. gstreamer and read by pix_video/pdp_v4l2 $ gstreamer dc1394src ! ffmpegcolorspace ! v4l2sink
if you are not on debian/sid, you might want to get v4l2loopback from http://github.com/umlaeute/v4l2loopback/ and simply run $ make $ sudo insmod ./v4l2loopback.ko
