Chunk Mode Timestamp about pylon-ros-camera

[m-binev]

@FlorianPfab Hi, well, to be honest I am not sure that using chunks on ROS has been implemented yet and I am not sure how it is supposed to work at all. I believe that what you are doing on ROS is not comparable to what is happening in pylon viewer and in the pylon APIs at all. That is, in pylon (or in GigE Vision), you are getting the chucks out of the image and not from the camera (what I believe you are doing). Please have a look at the pylon C++ API and the sample showing how chunks are extraxted out of the image: https://docs.baslerweb.com/pylonapi/cpp/sample_code#grab_chunkimage
As I'm not that big ROS expert, I cannot say if that is supposed to work in ROS like that or at all.
Hope that helps. Cheers

Hello @FlorianPfab
Working on the issue here. I can reproduce the problem. I'll investigate it more deeply after the Christmas holydays.

Hi @FlorianPfab
Thank you for reahing out. Working currently on the issue, it may be due to the way the pylon API is used. Coming back to you as dast as possible.

Hi @FlorianPfab
Did you have the chance to test the new driver version by any chance?
