Color Coding Error

[Paul Gray]

Hi all,
I am having trouble when trying to run the exampleTouchkitSimple;

Whenever I try to run it, I get this error:
libdc1394 error: RAW1394 failure: in _dc1394_format7_set_color_coding
(format7.c, line 195): Format7 color coding setting failure

This error happens when tracker->selectDevice(0); runs.

Just wondering if anybody else has run into this and if anyone has any
clue on how to fix it.

thanks!

P.S.
I am running Linux, I have the Unibrain Fire-i BBW 1.3 camera hooked
into my computer through the FireWire Port, and it is working
perfectly with Coriander(a program that utilizes the libdc1394
library)

Hi Paul, welcome to the list.

I am afraid to say that all the touchkit stuff is slightly specific to
the camera that currently ships with the hardware (point grey firefly
MV monochrome). We haven't gotten around making it work with other
firewire cameras.

If you want to tackle the issue yourself the first file to look at
would be VideoGrabberDc1394.cpp in the vaTouchkit addon. You probably
want to set the "framerate" to 30 and change the "video_mode" to
something supported by the fire-i. Looks like the primary error has to
do with a format7 mode that is not supported.

You can find more info on the firewire lib and format7 settings here:

Stefan,
Thanks so much for your quick response!

We are looking into getting a Firefly MV Camera, but we are not sure
what to get.
I talked with a representative from point grey and told her i needed a
point grey firefly MV monochrome, to which she told me that the
FFMV-03M2M-CS was what I was looking for. She said it was monochrome
and had 640x480 resolution.

I'm guessing that this^ is the camera that we need.
Also, she asked if I needed the dev kit along with it, but do we
really need that? We have all the cables necessary, and the point grey
dev kit comes with the "FlyCapture SDK (C/C++ API and device drivers)
CD" I figured we would not need the "official" drivers, because VA
uses the libdc1394 library, am I correct in assuming that?

thanks for all you help,
-Paul

hey chris,

Each time I check it seems there are more firefly MV models. But yeah,
FFMV-03M2M-CS is the one we are using.

They really like to sell the dev kit but I doubt you will find it
useful. VirtualAwesome/dc1394 will work without any drivers or
software you get in the kit.
