not able to read chunk data using aravis 0.8 (it worked with 0.6)

[weichselbaumj]

Describe the bug
Since upgrade to aravis 0.8 (from 0.6) reading chunk data does not work. I also tried the given example code (https://github.com/AravisProject/aravis/blob/main/tests/arvchunkparsertest.c), it does not work in my configuration.

To Reproduce

• compile https://github.com/AravisProject/aravis/blob/main/tests/arvchunkparsertest.c
• connect camera (FLIR-Blackfly S BFS-PGE-16S2C)
• start the test program

Expected behavior
Getting desired chunk data.

Camera description:

• FLIR
• FLIR-Blackfly S BFS-PGE-16S2C
• GigE

Platform description:

• Aravis version 0.8.30
• OS: Ubuntu 20.04
• x86_64

Additional context
Reading chunk data worked fine with aravis 0.6. Fore some reason we had to upgrade to aravis 0.8 and besides of the chunk data issue, everything works as expected.
Thanks for your help.

Could you attach the genicam data of your device ?
