FLIR camera not working

[guiwitz]

In order to benefit from recent changes in the software I tried to run the most recent version from master (46deda8). When starting the software I run into this issue with the FLIR camera:

In the code I see comments about like While we transition to AbstractCamera, we need to do some hacks here to make the non-transitioned drivers still work." so I guess this issue is related to this? I tried to debug but don't know enough about the drivers to figure out the problem.

It's definitely not a problem with the camera as the system works fine with older version of the software.

Yes FLIR camera support for the latest version of software is to be added (all the systems using FLIR cameras are in your lab)

Hi @hongquanli, thanks for the information. I hoped to see commits regarding this issue in the past weeks but didn't see anything (unless I missed it?). Do you have a time-line on when this will be added? We are kind of stuck right now with a "newish" version but can't benefit from the most recent bug fixes and improvements.
