Just in case it can interest someone, I finally solved the problem. The
issue was with my way of using the additional library python-aravis,
which is actually not really required. It is easy to use the aravis
library directly from Python to take snapshot pictures.
Best regards,
Philippe

I have a problem that maybe someone has already met. I use a DMK 23G445 based camera (The Imaging Source) with a GigE interface. My goal is to take snapshot pictures from a Raspberry Pi under Linux Raspian Jessie. I have compiled aravis without problems, I can see the camera and take pictures using the aravis library. However, for a reason I do not understand, the images I get are corrupted (for a short period of time following the install the images were correct then it did not work anymore). It seems I lose packets and I get black strips on the image. Here is an example of what I get (I use the camera to monitor the sky in an observatory -- obviously it was rainy this morning...):

I have tried many different things with the aravis settings without success. I suspected the Raspberry Pi 2 Model B does not have a fast enough Ethernet connectivity so I tried with a Banana Pi which has a GigE Ethernet port, but I get the same result.
Did you try to run arv-camera-test in the test directory ?
What does it say ?
Cheers,
Emmanuel.
