[Motmot] Fview color question

[James Waters]

We need to record video of ant colonies in FView that will be used for
two things, 1) Ctrax tracking, and 2) 'manual' frame by frame
behavioral observations.  That second project requires that the ants
be individually marked with color dots -- so we need to record color
video.

We're using a PtGrey Flea2 and Ubuntu 10.04 and all the latest
releases.  When initializing the camera and choosing a ...MONO8 video
mode, it works, but this is grayscale.  We get the following error
message when trying to initialize the camera using any RGB video mode:

Error opening camera

cam_iface_mega.c 305): /build/buildd/libcamiface-0.5.8/src/
cam_iface_dc1394.c (1118): Currently unsupported color coding

Here is the fview.log:

Is there any chance there is a quick fix for this?  If color recording
is not possible with this camera in FView at this time... can you
recommend any other programs?  If we absolutely had to, we could
record grayscale video in FView for use with Ctrax and then record a
second video in color in another program for the other
(color-necessary) analysis... but it would be really preferable to
have these data come from the same source video.

Thanks for your help!
