[Rock-dev] set up of camera_firewire

[Martin.Azkarate at esa.int]

Hi Janosch,

I changed the overwrites.yml file as you told, autoproj build the package 
again and tried that out but I'm still getting the same error...any other 
ideas?

Thanks for the help,

Hi Martin,
which branch of the driver are you using ?
As the line in the error message does not match
master I assume next or stable. 
We recently fixed bugs in this driver. 
Try switching (only the driver) to master.
To do so add these three lines to 
autoproj/overwrites.yml :
overrides:
    - drivers/camera_firewire:
      branch: master

Greetings
    Janosch

P.S.: We only tested this driver with a AVT guppy. For this camera it is 
working stable.

Hello, 

I have a Bumblebee2 camera that I am trying to use with the 
camera_firewire library package and its corresponding orogen component. I 
am running the following script: 





An getting the following error: 

--------- beginning of terminal output ---------------------- 

lrm at ubuntu:~/rock/drivers/orogen/camera_firewire/scripts$ ruby 
camera_firewire_live.rb 
Found 1 cameras:

Press ENTER to exit

camera::CamFireWire::checkHandleError(dc1394error_t) const) 

--------------------- end of terminal output ------------------- 


Actually the script is completely executed and a vizkit image window is 
opened but without any camera output, just a grey window with the message 
"no image" in the middle. So when I press enter to exit I get the 
libdc1394 error output in the terminal that you can see above. I am 
guessing that the error is in some setting of the libdc1394 library, I 
have tried complying with the BB2 camera specs and edited a couple of 
properties that should be the right ones but I still can't manage to get a 
camera output. The camera works and communicates properly with the 1394 
interface (checked it using Coriander). So, can anyone with experience in 
cameras with firewire interface give me a hint here? I add a couple more 
files in case these are helpful. 



Thanks for the help, 

Martin
