We have a great firewire camera that works well with dvgrab and kino to capture images on our Dapper box...but we can't get it to work w/ pdp/pidip. We were thinking to use coriander but coriander says the camera doesn't have the right specs. Then we tried using Gem, thinking we could then use the gem2pdp object to get it into pdp...but there is no help we could find for pix_video to figure out how to use that object and simple trial and error hasn't gotten us far...we aren't experienced with Gem, which isn't helping.
If we could find a way to convert from the raw1394 to video for linux, then our problems would be solved.
Any ideas?

The help patch and the folder full of examples should get you started...

Hi John,
I was using an Apple iSight recently on Linux and trying to get the
video into pdp. What I ended up doing was using vloopback (http://
www.lavrsen.dk/twiki/bin/view/Motion/VideoFourLinuxLoopbackDevice)
and dc1394_vloopback (one of the libdc1394 sample programs: http://
sourceforge.net/projects/libdc1394) and from there was able to pick
up the video using pdp_v4l.

to set [pix_video] to use DV in linux you need to send it the message
[driver 1( for DV --[driver 0( is for v4l -- but it was looking in
the wrong place for the device - at least a few months ago you needed
to compile a more recent Gem than the usual distribution so that you
could send a message to tell it to look for the correct /dev device,
rather than its default - this may be fixed in your distribution.
in the end I used a Tetra Piccolo framegrabber with 4x v4l inputs
instead so I didn't test out DV or recompile Gem. You may also have
to set [mode 0( if rectangle texturing isn't working properly - as
seems to happen on many platforms with recent Gem versions - if you
just get the centre pixel of the image spread over the whole frame.
